Question 1

Is Emulgent O-8 harmful to humans? Does it have an impact on the environment?

Accepted Answer

Emulgent O-8 poses clear health hazards to humans (skin irritation, serious eye damage, harmful if swallowed), and is also harmful to aquatic organisms with long-lasting effects. Strict protective measures must be taken during operation. Detailed Explanation Emulgent O-8 (tty alcohol polyoxyethylene (8) ether) is a nonionic surctant. Although it exhibits excellent performance in industrial applications, its safety classification indicates significant health and environmental risks. According to the GHS classification system, the hazard categories of this product include skin corrosion\/irritation (Category 2), serious eye damage\/eye irritation (Category 1), acute toxicity - oral (Category 4), and hazardous to the aquatic environment - chronic toxicity (Category 3). The signal word is "Danger", and both GHS05 (corrosive) and GHS07 (exclamation mark) pictograms must be used. From a human health perspective, the three core hazards of Emulgent O-8 are: harmful if swallowed (H302), causes skin irritation (H315), and causes serious eye damage (H318). This means that even a small amount of oral intake may cause toxic reactions. Direct skin contact can cause symptoms such as redness, swelling, and itching, while eye contact may lead to irreversible serious damage. Notably, its eye damage classification is the highest Category 1, the most severe level, r exceeding general irritation categories. From an environmental perspective, this product is classified as hazardous to the aquatic environment - chronic toxicity Category 3 (H412), harmful to aquatic organisms with long-lasting effects. This means that once released into natural waters, it not only causes immediate toxic effects but also persists due to its chemical stability, continuously harming aquatic ecosystems such as fish and plankton. Therefore, measures must be taken during operation and disposal to prevent the product from entering sewers, surce water, or soil. Key Safety Operation Points Based on the above hazard assessment, the following protective measures should be implemented during actual operations: Personal Protective Equipment (PPE): Protective gloves, protective clothing, eye protection, or ce shield must be worn (P280). Thoroughly wash skin after handling (P264). Do not take work clothing out of the workplace. Operating Environment: Operations should be carried out in a well-ventilated area. Do not eat, drink, or smoke when using this product (P270). Keep away from heat and ignition sources. Emergency Response: In case of skin contact, wash immediately with plenty of soap and water (P302+P352). In case of eye contact, rinse thoroughly with plenty of running water or normal saline for at least 15 minutes and seek medical attention immediately. Do not use any neutralizing agents. If swallowed, immediately call a poison center or doctor (P301+P312). Rinse mouth but do NOT induce vomiting. Environmental Protection: Avoid release to the environment (P273). Prevent entry into sewers or waterways. Absorb spillage with inert material and collect in closed containers for disposal. Storage Recommendations Store in a cool, dry, well-ventilated dedicated warehouse. Keep the container tightly closed to prevent moisture absorption. The warehouse temperature should not exceed 30°C, and the relative humidity should not exceed 75%. Keep away from oxidizers, acids, and food chemicals.

Question 4

Does Eumulgin O-8 meet environmental protection requirements? Can a test report be provided?

Accepted Answer

Eumulgin O-8 is a conventional industrial nonionic surctant with GHS environmental hazard classification (Hazardous to the aquatic environment - Chronic toxicity, Category 3). It is not a "green" certified product, but it complies with conventional chemical environmental management requirements. For test reports, you can obtain the product COA (Certificate of Analysis) and SDS (Safety Data Sheet) from Guoli Chemical. Detailed Explanation The environmental compliance of Eumulgin O-8 (C12-14 tty alcohol polyoxyethylene (8) ether) needs to be evaluated from multiple dimensions. According to the safety information in the Guoli Chemical product database, this product is classified as Hazardous to the aquatic environment - Chronic toxicity, Category 3, with the hazard statement H412 "Harmful to aquatic life with long lasting effects". This means that the product is not without environmental risk, and waste liquid must be properly treated before discharge. It is strictly prohibited to discharge it directly into sewers, surce water, or soil without treatment (P273). From the perspective of raw material sources, Eumulgin O-8 is produced by ethoxylation of C12-C14 natural tty alcohols. The raw materials themselves come from renewable resources (palm oil, coconut oil, etc.), and chemically, it belongs to linear tty alcohol polyoxyethylene ethers (AEOn). According to general chemical knowledge, this type of linear nonionic surctant typically has good primary and ultimate biodegradability and can be gradually decomposed by microorganisms under aerobic conditions. However, it should be noted that the database does not directly provide specific biodegradation rate data for this product (such as OECD 301B test results). Under the current environmental regulatory framework, Eumulgin O-8 is not classified as a PBT (Persistent, Bioaccumulative, and Toxic substance) or vPvB (very Persistent and very Bioaccumulative) substance, nor is it a Substance of Very High Concern (SVHC) under the EU REACH regulation. As a conventional industrial surctant, it can be used normally in various industrial formulations, provided that operating procedures and waste liquid treatment specifications are strictly followed. Regarding Test Reports According to the Guoli Chemical product database, the following quality documents are typically available upon product shipment: COA (Certificate of Analysis): Contains measured data for key physicochemical indicators such as appearance, active matter content (≥99%), hydroxyl value (90~105), water content (≤1.0%), pH value (5.0~7.0), etc. SDS (Safety Data Sheet/MSDS): Contains complete hazard classification, safe handling guidelines, emergency response, and transport information. If RoHS, REACH, or specific environmental test reports (such as biodegradability test reports, VOC content tests, etc.) are required, this is a special requirement that should be communicated in advance to the sales or technical service team at Guoli Chemical. We can assist in arranging third-party testing or provide existing compliance declaration documents. The database does not contain ready-made data for such specialized environmental test reports.

Green formulation development: If the product needs to pass green certifications such as Ecocert or EU Ecolabel, Eumulgin O-8 may not be fully applicable due to the presence of petrochemical-derived ethylene oxide segments. It is recommended to consult the certifying body for confirmation. Wastewater treatment: Wastewater containing Eumulgin O-8 after use should be directed to the enterprise's wastewater treatment system, undergo biochemical treatment, and be discharged up to standard. It must not be directly discharged into natural water bodies. Precautions During operation, it is essential to prevent product leakage into the environment (P273). Spills should be absorbed with inert materials and collected in sealed containers for disposal by qualified units. Although the product has biodegradation potential, this does not mean it can be directly discharged. High concentrations of surctants still impose a shock load on aquatic ecosystems. If formal environmental test reports or compliance declarations are required, please contact the Guoli Chemical sales department directly. We will provide corresponding support based on your specific needs.

Question 5

What are the advantages of Labiling/O-8 compared to other similar products?

Accepted Answer

Labiling/O-8 achieves an excellent balance between emulsifying power, permeability, and chemical stability through the precise EO chain length (n≈8) and the golden ratio of HLB value 11~12, with outstanding comprehensive performance among similar tty alcohol polyoxyethylene ethers. Detailed Explanation The core advantage of Labiling/O-8 (tty alcohol polyoxyethylene (8) ether, C12~14) lies in the precise match between the ethylene oxide addition number (EO=8) in its molecular structure and the C12-14 carbon chain. Among AEO series products on the market, those with lower EO numbers (e.g., AEO-3, AEO-5) are more oil-soluble, with HLB values between 6 and 10, mainly used for W/O emulsification or as lipophilic penetrants; while products with higher EO numbers (e.g., AEO-12, AEO-15) have strong hydrophilicity and high cloud points, but their penetrability and oil removal efficiency decrease. The EO number of Labiling/O-8 is exactly at the "inflection point": the HLB value of 11~12 endows it with excellent emulsification and solubilization capabilities for mineral oils, animal and vegetable oils, and various organic solvents, while maintaining a low surce tension of about 28~32 mN/m, and a penetrability (canvas settling method) of 15~30 seconds, balancing the two core properties of emulsification and permeability. Compared with similar products, another major advantage of Labiling/O-8 is its excellent chemical stability and compatibility in compounding. According to data from the Guoli Chemical database, this product has an effective content of ≥99% and a free alcohol content of ≤1.0%. High purity means minimal interference from side reactions in formulations. It remains stable in acid, alkali, and high-concentration electrolyte salt solutions, with outstanding hard water resistance and no formation of calcium soap precipitates. This makes Labiling/O-8 perform excellently under harsh conditions such as high-temperature scouring in textile pretreatment (alkali resistance), industrial hard surce cleaning (salt resistance), and pesticide formulation emulsification (electrolyte resistance), while some similar low-EO products or those with more impurities may experience precipitation or reduced surce activity under the same conditions. In addition, the cloud point (50~70°C, 1% aqueous solution) of Labiling/O-8 is just right—higher than that of low-EO products such as AEO-5 (usually 80°C). This means that in processes requiring a certain temperature, such as high-temperature washing and textile scouring, Labiling/O-8 will not easily precipitate and lose activity, while also having moderate foam characteristics, avoiding overflow problems and cilitating industrial operation and rinsing. Technical Parameters Parameter Labiling/O-8 (Guoli Chemical) AEO-7 (Typical Counterpart) AEO-9 (Typical Counterpart) CAS Number 68439-49-6 68439-50-9 68439-50-9 EO Number ≈8 ≈7 ≈9 HLB Value 11~12 About 10~11 About 12~13 Cloud Point (1% Aqueous Solution) 50~70°C About 40~55°C About 60~75°C Effective Content ≥99% Common market ≥98% Common market ≥98% Penetrability (0.1%, Canvas Settling Method) About 15~30 seconds About 20~35 seconds About 30~50 seconds Surce Tension (1%, 25°C) About 28~32 mN/m About 27~31 mN/m About 30~34 mN/m Free Alcohol Content ≤1.0% Usually ≤2% Usually ≤2% Chemical Stability Stable in acid, alkali, and salt solutions Generally stable in acids and alkalis Generally stable in acids and alkalis Application Recommendations For textile printing and dyeing: Labiling/O-8, with its excellent alkali resistance and permeability, is particularly suitable for high-temperature scouring processes of cotton and blended brics. The recommended dosage is 0.5%~2% (based on bric weight), which can effectively remove cotton wax and sizing, improving whiteness and capillary effect. For post-dyeing washing processes, a recommended dosage of 0.3%~1% is suggested, with strong ability to remove floating color without affecting the shade. For industrial cleaning: In heavy oil degreasing formulations, Labiling/O-8 can be used as the main surctant or compounded with anionic surctants (e.g., sulfonic acid, AES), accounting for 20%~40% of the active matter in the formulation, balancing oil removal efficiency and rinsability. Compounding with AEO-5 can further enhance oil removal power. For pesticide formulations: Used in emulsifiable concentrates, oil-in-water emulsions, and microemulsions, the recommended dosage is 3%~8% (based on total formulation), which can significantly improve the emulsification dispersion performance and dilution stability of the technical material. Better results are achieved when compounded with anionic emulsifiers (e.g., calcium salts). Precautions Labiling/O-8 is hygroscopic; keep the container sealed during storage, with a warehouse temperature not exceeding 30°C and relative humidity not exceeding 75%. Wear protective gloves and goggles during operation. This product is classified as a hazardous chemical (GHS05 corrosive), which can cause serious eye damage and skin irritation. It is recommended to use at a temperature below the cloud point (50~70°C). During high-temperature operations, note that the product may precipitate if the cloud point is exceeded, affecting surce activity. When compounding with anionic surctants, it is recommended to first conduct a small-scale compatibility test. Nonionic and anionic types generally have good synergistic effects, but the specific ratio needs to be adjusted according to formulation targets.

In formulation design, it is recommended to adjust the dosage according to specific process requirements: when used as an emulsifier, it typically accounts for 2%~8% of the total formulation; when used as a wetting and penetrating agent, the dosage can be appropriately reduced to 0.5%~3%. Compounding with anionic surctants (e.g., LAS, AES) can produce synergistic effects and enhance overall formulation performance. In pesticide formulations, Rubbing Alcohol/O-8 is suitable for preparing various dosage forms such as EC (emulsifiable concentrate), EW (oil-in-water emulsion), ME (microemulsion), etc., significantly improving the dilution stability of the formulation in hard water. In emulsion polymerization, it is recommended to be used in combination with nonionic-anionic composite emulsifier systems to achieve better polymerization stability and particle size control.

In formulation design, it can be compounded with other nonionic or anionic surctants to flexibly adjust the HLB value of the system to meet the emulsification requirements of different oil phases. Typical applications include: textile scouring agents and detergents (dosage 2%~8%), pesticide emulsifiable concentrate emulsifiers (dosage 5%~15%), industrial hard surce cleaners (dosage 3%~10%), emulsion polymerization emulsifiers (dosage 1%~5% based on monomer mass), and base components of metalworking fluids (dosage 5%~20%). Since the congelation point of the product is approximately 10~15°C, solidification or stratification may occur at low temperatures in winter, which is a normal physical phenomenon. Before use, rewarm at 20~30°C and stir evenly to restore performance, without affecting product quality. In processes requiring high-temperature operation, its cloud point of 50~70°C ensures that surce activity is not lost. Precautions
