Question 1

Is low-foam penetrating agent SF harmful to the human body? Does it have an impact on the environment?

Accepted Answer

Under normal use conditions, low-foam penetrating agent SF has very low harm to the human body and is not classified as a hazardous chemical, but direct discharge into environmental waters should be avoided. Detailed Explanation According to the product safety data provided by Guoli Chemical, low-foam penetrating agent SF (alcohol polyoxyethylene ether phosphate) does not ll into the physical, health, or environmental hazard categories defined by the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Toxicological tests show: rat acute oral toxicity LD₅₀ > 2000 mg/kg bw, rat acute dermal toxicity LD₅₀ > 2000 mg/kg bw, both within the low acute toxicity range. In the rabbit skin irritation test, the irritation score was less than 0.5, judged as non-irritating to the skin. Therefore, under industrial production and normal operating conditions, the health risk to operators from this product is controllable. In terms of the environment, low-foam penetrating agent SF is a nonionic surctant (with some anionic characteristics). The tty alcohol chains and polyoxyethylene ether segments in its molecular structure have a certain biodegradability potential in the natural environment. However, it should be noted that this product is strictly prohibited from being directly discharged into environmental waters, as large discharges may have adverse effects on aquatic organisms. The product safety instructions clearly require: avoid leakage into sewers or water bodies, and waste materials must be handed over to qualified waste treatment agencies for disposal; do not discharge at will. This indicates that although the product itself is not a highly toxic chemical, as a surctant industrial chemical, it still requires compliance with waste management responsibilities. In summary, under the premise of standardized operation and proper disposal, the risk of low-foam penetrating agent SF to human health and the environment is low. Wearing basic protective equipment (chemical safety goggles, protective gloves), maintaining ventilation in the workplace, and avoiding prolonged direct contact with skin and eyes can effectively control the use risk.

Emergency Treatment: In case of skin contact, immediately rinse with plenty of water and soap for at least 15 minutes; in case of eye contact, continuously rinse with water or saline for at least 15 minutes and seek medical attention. Environmental Considerations It is strictly prohibited to discharge the product directly into sewers, rivers, or soil. In case of leakage, use inert absorbent materials (such as vermiculite, sand) to collect and hand over to qualified agencies for disposal. Waste packaging must not be discarded arbitrarily and should be properly treated as industrial solid waste.

Question 2

What should I do if problems occur during the use of low-foam penetrant SF? How to get technical support?

Accepted Answer

If problems occur during the use of low-foam penetrant SF, it can be resolved through three steps: investigating common causes, checking technical parameters, and contacting the professional team of Guoli Chemical. Detailed explanation Low-foam penetrant SF is a stable nonionic surctant of tty alcohol polyoxyethylene ether phosphate (with anionic characteristics). If problems such as insufficient penetration, abnormal foam, or poor compatibility occur during use, they are usually related to product storage conditions, water quality, working fluid formulation compatibility, or usage concentration. According to the Guoli Chemical product database, this product withstands 300g/L NaOH strong alkaline solution, is resistant to hard water, has a cloud point ≥100°C, and is very stable under normal conditions. Therefore, it is recommended to start troubleshooting from operating conditions one by one. If the above self-check cannot solve the problem, you can directly contact the technical department of Haian Guoli Chemical Co., Ltd. for professional support. Although there is no independent technical support hotline page for this product publicly available in the database, you can obtain the latest technical services through the purchase channel (such as contact information marked on the product packaging or official sales personnel). Generally, Guoli Chemical provides formula guidance, application process optimization, and product quality consistency traceability services for its products. Common problem self-check list The following are typical problems and troubleshooting directions when using low-foam penetrant SF: 1. Insufficient penetration (slow or uneven wetting) Insufficient concentration: The penetration time of a 1% aqueous solution of this product at 25°C by the canvas sinking method is ≤10 seconds. If the treatment effect is poor, it is recommended to re-measure whether the actual addition amount reaches the recommended dosage (generally 0.1%~1.0%). Low temperature: At low temperatures, the activity of surctant molecules decreases. The working fluid can be appropriately heated (the product's cloud point ≥100°C, can be used from room temperature to high temperature). Hard water interference: Although the product is resistant to hard water, extremely high hardness water (e.g., Ca²⁺, Mg²⁺ > 500ppm) may affect some performance. You can test with soft water for comparison. Product ilure: Check whether the product has been exposed to moisture or contaminated by foreign substances due to long-term open storage. The product is slightly hygroscopic and should be sealed and stored in a cool and dry place at 5°C~35°C. 2. Abnormal increase in foam Compatibility issues: Low-foam penetrant SF itself has low and unstable foam, but if other high-foam surctants (such as AES, K12) are compounded in the formula, the foam may come from other components. Mechanical air entrainment: Air leakage from high-speed circulation pumps or excessively violent stirring can introduce air and cause foaming. Check the equipment sealing. Change in alkali concentration: Although resistant to strong alkalis, foam performance may vary slightly in different concentrations of alkali baths, and judgment should be made based on the actual process. 3. Poor compatibility (layering, precipitation, turbidity) Compatibility with other auxiliaries: It has good compatibility with anionic and nonionic auxiliaries, but if the system contains high concentrations of cationic auxiliaries (such as cationic softeners, fixing agents), electrostatic complexation may occur, leading to precipitation. Addition sequence: It is recommended to slowly add SF to water under stirring to dilute, then add other auxiliaries. Avoid directly pouring high-concentration acid or alkali into the SF raw liquid. Technical parameters Check whether there are changes in key product parameters related to the problem: Parameter itemTypical valueDescription AppearanceColorless to light yellow transparent liquidIf the color is significantly darker or turbid, it may have deteriorated Active content≥99%A decrease in solid content directly affects performance pH value (1% aqueous solution)5.0~7.0Deviation from this range may indicate acid or alkali contamination Penetration power (1%, 25°C)≤10 secondsCanvas sinking method; prolonged time indicates decreased product performance Alkali resistance stabilityResistant to 300g/L NaOHIf the required process alkali concentration is not tolerated, check whether the process conditions exceed the product design range Cloud point (1% aqueous solution)≥100°CA decrease in cloud point may reflect a change in product composition Kinematic viscosity (25°C)200~400 mm²/sAbnormal thickening or thinning indicates storage or quality issues Moisture content≤1.0%Excessive moisture may be due to packaging damage and moisture absorption (Source of above parameters: Guoli Chemical product database) Application recommendations For different application fields, the following verifications are recommended: Textile desizing/scouring: The recommended dosage of SF in the working fluid is 0.2%~0.5% (based on bric weight), used with alkali agents and hydrogen peroxide. Add water first, then add SF and stir to dissolve evenly. High-pressure spray cleaning: Due to the dynamic circulation of the system being prone to foaming, the low-foam property of SF is significant in this scenario. Recommended addition amount is 0.1%~0.3%. When compounding with chelating agents, corrosion inhibitors, etc., first perform a small-scale compatibility test. Paper deinking: The deinking temperature is usually 60~80°C, which is within the cloud point range of SF. Recommended dosage is 0.05%~0.2% (based on pulp weight), used with sodium hydroxide, water glass, etc. for flotation deinking. Pesticide adjuvant: As a tank-mix adjuvant, the dosage is generally 0.05%~0.1% of the spray solution. Excessive dosage may cause excessive spreading and runoff. Conduct small-scale field tests to determine the optimal addition ratio. If the problem still cannot be solved after self-check and testing, contact Guoli Chemical to provide batch traceability information (drum batch number and production date), along with a problem description and working fluid conditions (pH, temperature, water quality, formula composition) to allow technical personnel to quickly locate the issue. Notes Although this product is not classified as a hazardous chemical, protective gloves and goggles should still be worn during operation to avoid prolonged skin contact. Waste working fluid and empty drums should be disposed of in accordance with local environmental regulations; do not discharge directly into water bodies. Different batches of product may have slight fluctuations in indicators within the allowable range, but all key parameters should meet the ctory standard of the enterprise. For exact technical support phone number or email, it is recommended to refer to the product inspection report (COA) accompanying the shipment or contact the sales department of Guoli Chemical.

Question 5

What are the advantages of low-foam penetrant SF compared to similar products?

Accepted Answer

The core advantage of low-foam penetrant SF lies in its unique molecular structure with "nonionic + anionic characteristics", achieving comprehensive performance that is difficult for similar products to balance simultaneously in four dimensions: extremely low foam, super strong alkali resistance (300g/L NaOH), rapid penetration, and wide chemical compatibility. Its advantages are most prominent in applications requiring low foam and strong alkaline environments. Detailed Explanation Compared to anionic penetrants (such as rapid penetrant T series), low-foam penetrant SF has the greatest differentiated advantage in its perfect combination of low-foam characteristics and alkali resistance. Although penetrant T (sodium diisooctyl sulfosuccinate, CAS: 577-11-7) has extremely st penetration speed, it generates a large amount of foam in dynamic circulation systems, easily causing overflow and equipment ilure; in contrast, low-foam penetrant SF maintains excellent penetration power (canvas sinking method ≤10 seconds) while having low and unstable foam, fundamentally solving the foam problems in spray cleaning and high-speed circulation processes. Compared to similar tty alcohol polyoxyethylene ether phosphate ester products (such as alkali-resistant penetrant AEP, OEP-70), low-foam penetrant SF has a more refined molecular design—its hydrophobic group is a C12-14 alkyl chain, EO polymerization degree is about 9, and monoester content ≥60%. This makes it particularly excellent in strong alkali resistance (withstanding 300g/L NaOH solution), significantly outperforming conventional alkali-resistant penetrants. At the same time, its HLB value is 11~13, and its cloud point is ≥100°C, so it does not precipitate or il due to temperature increase in high-temperature processes, ensuring process stability in high-temperature scouring, desizing, and other steps. In terms of safety and environmental protection, low-foam penetrant SF also demonstrates competitive advantages: the product is not classified as a dangerous chemical, acute oral/dermal toxicity LD50 is >2000 mg/kg bw, skin irritation score is Technical Parameters Performance IndicatorLow-Foam Penetrant SFComparison with Typical Industry Penetrants Ion TypeNonionic (with anionic characteristics)Penetrant T is purely anionic, limited in alkali resistance and compatibility Penetration Power (1% aqueous solution)≤10 seconds (canvas sinking method)At the same level as rapid penetrant T, st penetration Foam CharacteristicsLow foam, low and unstable foamRapid penetrant T produces large amounts of foam, requiring additional defoamer Alkali ResistanceResists 300g/L NaOH solutionPenetrant T easily hydrolyzes and ils in high-concentration alkali HLB Value11~13Combines emulsifying and wetting functions, wide application range Cloud Point (1% aqueous solution)≥100°CSuitable for high-temperature processes, no precipitation or ilure Surce Tension (0.1%, 25°C)Approx. 30 mN/mStrong wetting and spreading ability Chemical Medium ResistanceAcid-resistant, alkali-resistant, hard water-resistantStable over a wide pH range, strong process adaptability Skin IrritationNon-irritating (rabbit score Some anionic penetrants are significantly irritating Dangerous Goods ClassificationNon-dangerous chemicalLow storage, transportation, and compliance costs Application Recommendations Based on the comprehensive advantages of low-foam penetrant SF, it is recommended to prioritize it in the following scenarios: Strong alkali pretreatment processes: In processes requiring high-concentration caustic soda (100~300g/L NaOH), such as cotton bric mercerizing and scouring, SF is an ideal mercerizing penetrant, ensuring uniform penetration of the alkali solution into the fiber and avoiding uneven surce treatment. High-pressure spray/circulation cleaning systems: In CIP online cleaning, high-pressure spray cleaning of metal parts, etc., the low-foam characteristic prevents foam overflow and ensures normal equipment operation. High-temperature processes: Cloud point ≥100°C, stable performance in high-temperature (80~95°C) processes such as desizing and scouring, without precipitation due to cloud point limitations. Applications with high safety requirements: Cleaning of food processing equipment, scenarios with possible human contact, leveraging its low toxicity and non-irritating properties to reduce usage risks. Blending for synergistic effects: Can be blended with anionic, cationic, and amphoteric surctants, used as an agricultural adjuvant to improve the spreading and penetration ability of pesticide solutions. Notes This product is slightly hygroscopic. After opening, it should be sealed and stored, avoiding prolonged exposure to humid air. Recommended storage temperature range is 5°C~35°C, avoid direct sunlight, and keep away from strong oxidizing agents. Although it has excellent alkali resistance, it is recommended to conduct small-scale tests to verify compatibility in special high-concentration electrolyte formulations. This product is nonionic (with anionic characteristics); when blending with cationic systems, sufficient verification of compatibility stability should be performed.

Question 6

How should low-foam penetrant SF be stored? What is its shelf life?

Accepted Answer

Low-foam penetrant SF should be stored in a cool, dry, and well-ventilated warehouse, with the temperature controlled between 5°C and 35°C, and kept sealed. Official data has not yet provided a clear shelf life, but similar nonionic surctants under compliant storage conditions can typically be stably stored for 12 to 24 months. Detailed Explanation Low-foam penetrant SF (tty alcohol polyoxyethylene ether phosphate) is a nonionic surctant with relatively stable chemical properties. The core objectives of its storage are to prevent moisture absorption and deterioration, avoid molecular structure degradation caused by high temperatures, and prevent contamination by impurities. As long as it is stored strictly according to the recommended conditions, the product can maintain its key properties such as low foaming and penetrating power for an extended period. Regarding the shelf life, the Guoli Chemical product database has not yet provided a clear shelf life for this product. This is a common situation in the chemical industry—many industrial surctants have good chemical stability and do not have obvious ilure points under ideal storage conditions. However, from the perspective of industry practice and quality control, it is recommended that users prioritize use of the product within 12 months after receipt, and it should not exceed 24 months at most. If this period is exceeded, samples should be tested for appearance, pH, and penetrating performance before use to ensure they are qualified. If during storage the product is found to have abnormal phenomena such as stratification, turbidity, significant color deepening, or unpleasant odor, even if it is still within the recommended period, it should be stopped and quality verification should be carried out. This usually means the product may have been dampened or contaminated. Storage Condition Requirements Storage ElementSpecific Requirement Ambient TemperatureShould be controlled between 5°C and 35°C, avoiding high temperature and low-temperature freeze-thaw cycles Storage EnvironmentCool, dry, well-ventilated dedicated warehouse, avoiding direct sunlight Container StatusKeep sealed to prevent moisture absorption or entry of foreign objects Substances to AvoidKeep away from heat sources, ignition sources, and incompatible materials (such as strong oxidizers) Segregation RequirementsStrictly prohibit mixed storage with food, feed, and drinking water Protective cilitiesShould be equipped with spill containment cilities such as leak-proof trays Inspection FrequencyRegularly check packaging integrity; if leakage is found, transfer immediately and handle properly Application Recommendations To maximize product service life, it is recommended to follow the first-in, first-out principle and prioritize using inventory from earlier batches. After each use, the drum lid should be immediately closed to reduce product exposure to air. If large quantities are purchased and need to be stored for a long time, consider repackaging large drums into small, sealed containers to reduce the risk of contamination from repeated opening of the same container. Precautions This product is not a flammable liquid and has relatively high storage and transport safety. However, it may decompose when heated in a fire, producing harmful gases. It should still be kept away from fire sources. Empty containers may have product residue; they must not be used to hold other substances without professional cleaning. Waste products and contaminated packaging should be disposed of as industrial solid waste by qualified waste treatment agencies. Do not discharge into the environment. If you need to confirm the usability of a product that has exceeded its storage period, it is recommended to contact Guoli Chemical technical support for sample evaluation.

Detailed Description The chemical nature of low-foam penetrant SF (CAS number: 26468-86-0) is tty alcohol polyoxyethylene ether phosphate, with a molecular weight of approximately 676 (calculated as monoester). It appears as a colorless to light yellow transparent liquid. This product belongs to nonionic surctants, but due to the introduction of phosphate ester groups in its molecular structure, it actually exhibits some anionic characteristics. Its HLB value is between 11 and 13, providing a balanced hydrophilic-lipophilic property, capable of effectively reducing the surce tension of an aqueous solution to about 30 mN/m (0.1% aqueous solution, 25°C). The critical micelle concentration is approximately 150 mg/L, demonstrating excellent wetting and spreading ability. The core physicochemical characteristic of this product lies in its excellent low-foaming property and rapid penetrating power. According to the data from GUOLI Chemical, the penetration time measured by the canvas sedimentation method for a 1% aqueous solution at 25°C does not exceed 10 seconds, with extremely low foam generation and unstable foam, making it highly suitable for dynamic circulation cleaning or high-pressure spraying systems. At the same time, the product exhibits excellent chemical stability, resisting acids, alkalis, and hard water, especially tolerating NaOH strong alkali solutions at concentrations up to 300 g/L, which is at the top level among similar surctants, making it an ideal choice for high-concentration alkali processes such as mercerizing. The product has an active content ≥ 99%, moisture content ≤ 1.0%, density of 1.05~1.10 g/cm³ (25°C), dynamic viscosity of 200~400 mm²/s (25°C), flash point > 150°C, pour point Technical Parameters Parameter CategoryParameter NameTechnical IndicatorRemarks Basic InformationChemical Nametty alcohol polyoxyethylene ether phosphateMonoester + diester mixture CAS Number26468-86-0— AppearanceColorless to light yellow transparent liquid— Molecular PropertiesMolecular WeightApproximately 676Calculated as monoester Ion TypeNonionic (with anionic characteristics)— Physical PropertiesDensity (25°C)1.05~1.10 g/cm³— Dynamic Viscosity (25°C)200~400 mm²/s— Low Shear Viscosity (25°C)300~500 mPa·s— Refractive Index (25°C)1.450~1.460— Melting Point / Pour PointLiquid at room temperature Flash Point> 150°CNon-flammable liquid HygroscopicitySlightly hygroscopic— SolubilityEasily soluble in water— Cloud Point (1% Aqueous Solution)≥ 100°C— Surce Activity ParametersHLB Value11~13— Surce Tension (0.1% Aqueous Solution, 25°C)About 30 mN/m— Critical Micelle Concentration (CMC)About 150 mg/L— Penetrating Power (1% Aqueous Solution, 25°C, Canvas Sedimentation Method)≤ 10 secondsCore performance Foaming CharacteristicLow foam, few and unstable bubblesCore performance Alkali ResistanceResistant to 300 g/L NaOH solutionExcellent Chemical StabilityResistant to acids, alkalis, and hard water— pH Value1% Aqueous Solution5.0~7.0— 5% Aqueous Solution6.0~8.0— Active Ingredient Content≥ 99%— Chemical IndicatorsAcid Value80~120 mgKOH/g— Saponification Value120~150 mgKOH/g— Hydroxyl Value≤ 10 mgKOH/g— Iodine Value≤ 1— Amine Value≤ 1 mgKOH/g— Moisture Content≤ 1.0%— Monoester Content≥ 60%— Diester Content≤ 40%— Free Phosphoric Acid≤ 1.0%— Free Alcohol≤ 3%— Combined Phosphorus (calculated as P₂O₅)8~10%— Safety and Limit IndicatorsUnsaturation≤ 0.1 mmol/g— Tertiary Amine Content≤ 0.5%— Total Heavy Metals≤ 20 mg/kg— Packaging Specifications50 kg/200 kg plastic drums, IBC tote tank— Application Recommendations Based on the above physicochemical parameters, low-foam penetrant SF is particularly suitable for the following scenarios: ① In the textile industry for desizing, scouring, mercerizing, and dyeing pretreatment processes, its resistance to 300 g/L strong alkali and rapid penetrating power of ≤ 10 seconds can greatly enhance processing efficiency and leveling; ② In industrial high-pressure spray cleaning and CIP inline cleaning, the low-foam characteristic effectively avoids foaming overflow issues; ③ In pesticide formulations as a wetting and penetrating synergist, utilizing its low surce tension and low CMC value to enhance the spreading ability of the liquid on plant leaves. It is recommended to use a conventional concentration range of 0.1%~1%, with specific dosages optimized through gradient experiments based on process conditions and penetration requirements. Precautions This product is slightly hygroscopic. After opening, it should be sealed and stored promptly to prevent moisture absorption that may affect quality.
