Question 2

What should I do if problems occur during the use of Isotridecyl Alcohol Phosphate E-1306P? How to obtain technical support?

Accepted Answer

If you encounter problems during use, please refer to the product safety data sheet for emergency treatment first, and then obtain professional technical support through the official channels of Guoli Chemical. Common usage problems and troubleshooting ideas Isotridecyl Alcohol Phosphate E-1306P, as an anionic phosphate surctant, may encounter the following typical problems in practical applications. It is recommended to check them one by one: 1. Unstable emulsion or working fluid (stratification, demulsification, turbidity) — First, check whether the pH value of the system is within the appropriate range. Although E-1306P has excellent acid-base stability, extreme pH conditions may still affect its emulsifying performance. Secondly, confirm whether the water hardness is too high. Calcium and magnesium ions in hard water may react with anionic phosphate groups. It is recommended to use deionized water or add an appropriate amount of chelating agent (such as EDTA) to improve. Also check whether other surctants or additives in the formulation are compatible with the anionic system. Cationic additives may cause ionic conflicts leading to demulsification. 2. Lubricity or extreme pressure performance is not as expected — Confirm whether the actual amount of E-1306P added is sufficient. In metalworking fluids, the recommended dosage is usually 0.5% to 5% of the total formulation, and the specific amount should be optimized through gradient tests based on processing conditions (material, speed, load). At the same time, check whether the system contains components that cause competitive adsorption or chemical consumption, such as certain active sulfur or chlorine extreme pressure agents that may alter the adsorption behavior of the phosphate ester on metal surces. 3. Severe foaming problem — E-1306P itself has certain foaming properties. If foam affects the operation, an appropriate amount of defoamer (such as silicone or polyether defoamer) can be added in combination, but attention should be paid to the compatibility of the defoamer with the system to avoid shrinkage cavities or surce defects. Lowering the operating temperature and reducing mechanical stirring intensity can also help control foam. 4. Poor cleaning effect or residue — In alkaline cleaning formulations, it is recommended to use E-1306P in combination with a builder (such as sodium metasilicate, sodium gluconate, etc.) to achieve synergistic effects. The cleaning temperature is recommended to be controlled at 50~80°C. Too low a temperature will reduce penetration and emulsification efficiency. If white residue spots appear, rinse thoroughly with warm water or appropriately reduce the concentration of E-1306P. Emergency safety treatment If accidental contact or leakage occurs during use, strictly follow the following emergency measures: Skin contact: Immediately remove contaminated clothing, rinse thoroughly with plenty of running water and soap for at least 15 minutes. If irritation persists, seek medical attention immediately. Eye contact: Immediately open eyelids and rinse continuously with plenty of running water or saline for at least 15 minutes. Seek medical attention as soon as possible. Inhalation discomfort: Move to fresh air quickly, keep airway open, and seek medical attention if necessary. Spill treatment: Collect with inert absorbent material (sand, vermiculite), place in a sealed container, and dispose of as hazardous waste. Do not discharge into water bodies.

Question 4

Is isotridecanol phosphate ester E-1306P compliant with environmental requirements? Can a test report be provided?

Accepted Answer

Under normal conditions, isotridecanol phosphate ester E-1306P has good chemical stability and extremely low levels of harmful impurities such as heavy metals. However, because it is harmful to aquatic life, it is not considered a 'green and harmless' chemical. Its environmental compliance needs to be evaluated in conjunction with specific regulations. Test reports (such as SDS, TDS, COA, etc.) can be obtained by contacting Guoli Chemical. Detailed Description The environmental characteristics of isotridecanol phosphate ester E-1306P (CAS: 9043-30-5) need to be viewed dialectically from two dimensions: On one hand, according to Guoli Chemical's product database, the product has heavy metal content ≤10 mg/kg, arsenic content ≤2 mg/kg, free phosphoric acid ≤0.5%, and no amine value detected, indicating high purity and extremely low risk of persistent organic pollutants and heavy metal residues. On the other hand, its safety instructions clearly state 'harmful to aquatic life,' and the leakage emergency treatment requires 'avoid entering water bodies, treat as hazardous waste,' so it is not a product without environmental risk. Regarding 'whether it meets environmental requirements,' the answer to this question is highly dependent on the specific regulatory framework and application scenario (such as EU REACH regulations, China's 'Measures for the Environmental Management Registration of New Chemical Substances', textile industry ZDHC MRSL, etc.). Guoli Chemical's product database currently does not provide specific regulatory compliance declarations for this product (such as REACH registration number, MRSL compliance statement, biodegradation rate data, etc.). It is recommended that you compare the product parameters such as heavy metal and arsenic limits based on your industry and export destination requirements, or directly contact Guoli Chemical for confirmation. Regarding test reports, the database shows that the product has detailed theoretical parameters and physicochemical indicators. Usually, Guoli Chemical will provide a Certificate of Analysis (COA) and Safety Data Sheet (SDS). If you need specific test reports issued by third-party authoritative organizations (such as SGS RoHS testing, ZDHC compliance report, biodegradability test report, etc.), you need to directly apply to Guoli Chemical's sales or technical department for verification. Technical Parameters (Environment/Safety Related Indicators) Parameter ItemSpecification/ValuePotential Environmental/Safety Significance Total Heavy Metals≤10 mg/kgExtremely low limit meets the initial requirements of most environmental regulations Arsenic (As) Content≤2 mg/kgBelow the strict limits for general industrial chemicals Free Phosphoric Acid≤0.5%Low free acid reduces the risk of eutrophication contribution to water bodies pH Value (1% Aqueous Solution)5.0~7.0Near neutral to slightly acidic, with less impact on pH during treatment Chemical StabilityStable under normal conditionsNot easy to decompose to produce currently unknown highly toxic by-products Aquatic HazardHarmful to aquatic lifeStrictly prohibited from direct discharge into water bodies, wastewater treatment required Iodine Value (Unsaturation)≤0.5Low unsaturation, chemically stable, not easy to oxidize and deteriorate Application and Compliance Recommendations When using or compounding, if the end product requires 'environmentally friendly' or 'green' labeling, it is recommended that you take the following steps: Request compliance documents: Contact Guoli Chemical, clearly inform them of the environmental standards you need to meet (such as OEKO-TEX, GOTS, USDA BioPreferred, etc.), ask whether E-1306P is included in the corresponding certification list, or request the latest compliance statement letter. Review Sections 12-15 of SDS: Carefully check the ecotoxicological information, disposal considerations, and regulatory information in the Safety Data Sheet to determine whether its classification meets project expectations. End-of-pipe treatment support: Because it is harmful to aquatic life, industrial cleaning or metalworking fluids must be equipped with effective wastewater treatment cilities after use to ensure discharge compliance. Notes This response is based on the existing information in Guoli Chemical's product database. Specific certification status not present in the database (such as ZDHC Level, REACH registration number, readily biodegradable %, etc.) is considered 'no data available', and the official test report shall prevail. Even if the content of harmful impurities is extremely low, it must never be classified as a 'non-toxic and harmless' chemical. Operational procedures must still be followed to prevent leaks and spills that could cause water pollution.

Question 5

What are the advantages of Isomeric Tridecanol Phosphate E-1306P compared to other similar products?

Accepted Answer

According to the technical data of Guoli Chemical, as an anionic surctant, the core advantage of Isomeric Tridecanol Phosphate E-1306P (E-1306P) lies in the efficient combination of **excellent extreme pressure lubricity, outstanding penetrating wetting ability, and superior chemical stability**. This makes it exhibit stronger comprehensive performance than many conventional nonionic or anionic surctants in several key fields such as metalworking, industrial cleaning, and textile auxiliaries. ### Detailed Description E-1306P is designed to have significant advantages in high-intensity application scenarios: 1. **Excellent Extreme Pressure Lubricity**: This is its most prominent advantage in the field of metalworking fluids. Under harsh boundary lubrication conditions such as cutting and grinding, E-1306P can quickly form a tough chemical protective film on the metal surce, significantly reducing the friction coefficient and processing temperature, thereby effectively reducing tool wear, extending tool life, and improving the machining accuracy and surce finish of the workpiece. Compared to ordinary lubricants or emulsifiers, the extreme pressure protection it provides is more direct and efficient. 2. **Outstanding Penetrating and Wetting Ability**: Benefiting from the branched chain structure of isomeric tridecanol and the balance of polyoxyethylene chains, E-1306P can extremely quickly lower the surce tension of liquids. This allows it to rapidly penetrate into fiber bundles, tiny gaps on metal surces, or deep holes in complex workpieces, ensuring uniformity of treatment. In textile pretreatment, this means higher cotton wax removal efficiency and greater capillary effect (whiteness); in industrial cleaning, it means stronger stripping ability for heavy oil stains. 3. **Excellent Chemical Stability**: As a phosphate ester anionic surctant, E-1306P exhibits good compatibility and stability over a wide pH range (acidic and alkaline) and in hard water systems, and is not prone to hydrolysis or precipitation. This ensures its effectiveness in complex formulations such as high-alkaline cleaners and acidic electroplating baths, an advantage that many nonionic surctants, which are not resistant to acids and alkalis, do not have. Its outstanding alkali resistance, especially its stability in a 100g/L NaOH solution, makes it a key component of high-performance pretreatment auxiliaries and industrial cleaners. ### Specific Data Although this query did not provide all quantitative comparison values, the following technical parameters can partially explain its performance advantages: | Parameter | Specification | Advantage Explanation | | :--- | :--- | :--- | | **Appearance** | Light yellow transparent viscous liquid | Suitable for high-value-added formulations with good appearance. | | **Ionic Type** | Anionic | Excellent compatibility with anionic components in the system (e.g., alkali agents, corrosion inhibitors). | | **Chemical Stability** | **Alkali resistant, stable in 100g/L NaOH solution** | Gives it excellent adaptability in high-alkalinity industrial cleaners and scouring agents, reducing auxiliary dosage. | | **Penetration Power** | **≤10 seconds (standard canvas sedimentation method)** | Directly reflects its rapid spreading and penetrating ability, key to its high efficiency in textile and cleaning fields. | | **Solubility** | Easily soluble in water | Convenient for preparing water-based formulations and easy to use. | ### Application Suggestions Based on its advantages, E-1306P is competitive in the following application scenarios: - **Metalworking Fluids (especially recommended)**: Used as a core extreme pressure anti-wear agent and corrosion inhibitor in emulsified oils, semi-synthetic, and fully synthetic cutting fluids. It is recommended to add **3% - 15%** in the concentrate to significantly improve lubrication and anti-rust performance. - **High-Performance Industrial Alkaline Cleaners**: As a penetration enhancer component. In heavy-duty cleaning formulations, it is recommended to add **1% - 5%** to enhance the stripping and emulsification effect on metal surce grease and carbon deposits. - **Textile and Dyeing Pretreatment Auxiliaries**: As the main component of scouring agents and penetrants. In scouring agent formulations, it is recommended to add **5% - 20%** to achieve excellent capillary effect and whiteness, superior to conventional penetrant JFC (tty alcohol polyoxyethylene ether). - **Electroplating Bath Additives**: As a dispersing wetting agent and auxiliary brightener. In nickel, zinc, and other plating baths, adding **0.01 - 0.1g/L** helps reduce pinholes and pits in the coating and improve throwing power. ### Precautions - **Irritation**: This product is an acidic phosphate ester and has **significant irritation** to the skin and eyes. During operation, personal protective equipment such as impermeable gloves and chemical safety glasses must be strictly worn. - **System Compatibility**: As an anionic surctant, thorough compatibility tests must be conducted before compounding with a large amount of cationic substances (e.g., quaternary ammonium salt fungicides) to avoid precipitation or ilure. - **Storage**: It is recommended to store in a cool, dry, well-ventilated environment at 5-40°C, and keep the packaging drum sealed to prevent moisture absorption or contamination.

Question 8

How to use isotridecyl phosphate ester E-1306P? What is the recommended dosage?

Accepted Answer

Isotridecyl phosphate ester E-1306P is an acidic anionic phosphate ester surctant, easily soluble in water. It is usually added directly or pre-diluted into the formulation system. The recommended dosage varies greatly depending on the application area, generally ranging from 1% to 15% of the total system amount. The optimal dosage should be determined through orthogonal experiments. Detailed Description Isotridecyl phosphate ester E-1306P (CAS: 9043-30-5) is an anionic surctant produced by phosphation of isotridecyl polyoxyethylene ether (n≈6). It appears as a pale yellow transparent viscous liquid with an active content ≥95% and is easily soluble in water. It combines the extreme pressure lubricity of phosphate ester groups with the penetrating and wetting properties of EO chains, making it a multifunctional additive. According to the Guoli Chemical product database, the HLB value of this product is between 7.0 and 9.0, classifying it as a lipophilic-hydrophilic balanced surctant. It can serve both as a co-emulsifier in O/W emulsification systems and as a lubrication and corrosion inhibition component in concentrates. The pH of a 1% aqueous solution is 5.0~7.0 (near neutral), but at 5% concentration, the pH drops to 2.0~4.0 (acidic). Therefore, attention must be paid to the acid-base compatibility of the system when preparing high-concentration premixes. In terms of usage, E-1306P can be directly added to the formulation via cold blending or warm mixing (recommended operating temperature not exceeding 40°C), or it can be pre-diluted with deionized water to 10%~20% concentration before addition to cilitate uniform dispersion. It is recommended to add slowly under stirring to avoid local high concentration leading to gelation or precipitation.

Question 10

What are the physicochemical technical parameters of isomeric tridecanol phosphate E-1306P?

Accepted Answer

Isomeric tridecanol phosphate E-1306P is an anionic phosphate ester surctant with excellent extreme pressure lubricity, penetration wettability, and chemical stability. Multiple physicochemical parameters have been fully measured. Detailed Description Isomeric tridecanol phosphate E-1306P (CAS No.: 9043-30-5) is an anionic surctant produced by Guoli Chemical using isomeric tridecanol polyoxyethylene ether (n≈6) as raw material through phosphation. The product appears as a light yellow transparent viscous liquid, easily soluble in water, with a molecular weight range of approximately 800~1000, and an HLB value between 7.0 and 9.0. It belongs to the lipophilic-hydrophilic balanced emulsifier, combining good emulsifying dispersion ability and wetting permeability. The phosphate ester composition of this product mainly consists of monoesters (50%~70%) and diesters (25%~40%). The high monoester content ensures excellent water solubility and emulsifying power, while the appropriate amount of diester imparts outstanding extreme pressure lubricity and anti-rust/corrosion inhibition ability. The product has a free phosphoric acid content ≤0.5%, free alcohol ≤3.0%, active matter content ≥95%, high purity, and few by-products, resulting in minimal interference with the system in practical applications. In terms of surce activity, the surce tension of a 1% aqueous solution of E-1306P can be reduced to 35~40 mN/m, with a critical micelle concentration (CMC) in the range of 1×10⁻⁴~1×10⁻³ mol/L. It has moderate foaming ability but performs as a low-foaming product, making it especially suitable for industrial formulations sensitive to foam. The product has strong alkali resistance and can maintain stable wetting and penetration activity in high-alkalinity industrial cleaning and textile pretreatment systems.
