Accepted Answer

600P-85% is a low-toxicity substance, posing a low health risk to humans under normal industrial use, but it may have potential long-term adverse effects on the aquatic environment and is not readily biodegradable. Detailed Explanation 600P-85% tristyrylphenol polyoxyethylene ether phosphate is classified as a low-toxicity substance in toxicological classification. Acute toxicity data shows that the rat oral LD50 is greater than 2000 mg/kg, indicating low acute toxicity from a single ingestion. Under normal industrial conditions, the health risk to humans is low; however, standard protective measures should still be followed during operation to avoid unnecessary direct contact. This product has certain irritating effects on the skin and eyes. Direct contact may cause mild skin irritation, and eye contact can lead to irritant symptoms. Based on evaluation data of similar chemical structures, this product is not a skin sensitizer, and there are currently no known reproductive toxic effects. However, it is still recommended to wear chemical safety goggles, chemical-resistant protective gloves, and protective clothing during operation to avoid prolonged or repeated direct contact. In terms of environmental impact, this product may have low toxicity to aquatic organisms. However, due to its surctant properties, large-scale leakage into water bodies should be strictly avoided, as there is a potential risk of long-term adverse effects on the aquatic environment. It is particularly important to note that this substance is not readily biodegradable, meaning it may persist in the environment. Waste disposal must strictly comply with local environmental regulations, and any leakage must not be discharged directly into sewers, soil, or any water bodies.

Question 4

Does 600P-85% tristyrylphenol ethoxylate phosphate meet environmental requirements? Can a test report be provided?

Accepted Answer

This product is not readily biodegradable, poses potential risks to the aquatic environment, does not belong to green and environmentally friendly surctants, and requires strict emission control. Detailed Explanation of Environmental Compliance According to the safety and ecological information in the Guoli Chemical product database, the environmental performance of 600P-85% tristyrylphenol ethoxylate phosphate is as follows: Biodegradability: This substance is not readily biodegradable, meaning it has high persistence in the natural environment and does not meet the current general requirement of "easy biodegradability" for surctants in green chemistry. After industrial use, if discharged without proper treatment, it may persist in the environment for a long time. Ecotoxicity: The product has low toxicity to aquatic organisms, but the database clearly states: "Due to its surctant properties, large-scale leakage into water bodies should be strictly avoided, as there is a potential risk of long-term adverse effects on the aquatic environment." This indicates that although acute toxicity is low, long-term exposure may still have cumulative effects on aquatic ecosystems. Regulatory Compliance: The product itself is a legally produced industrial chemical and complies with usage specifications in normal industrial applications. However, its environmental compliance is conditional—it is necessary to ensure that the waste liquid after use is professionally treated, strictly prohibited from being directly discharged into sewers, soil, or any water bodies, and disposal must follow local environmental regulations. If the application scenario has clear requirements for biodegradability (e.g., certain eco-certified formulations), its suitability needs to be evaluated. Regarding Test Reports Currently, the Guoli Chemical product database does not contain a complete third-party environmental test report for this product (such as biodegradation rate report, aquatic ecotoxicity test report, ROHS/REACH compliance test report, etc.). If specific test data is required, it is recommended to obtain it through the following channels: Contact the Guoli Chemical sales or technical department directly to apply for an official quality inspection report (COA) and related environmental testing documents Commission a third-party testing institution with CMA/CNAS qualifications to conduct targeted tests based on your specific application scenario Environmental Usage Recommendations In scenarios where the use of this product is necessary, it is recommended to take the following environmental control measures: Ensure that production waste liquid is effectively treated (e.g., chemical oxidation, activated sludge method, membrane separation, etc.) and meets discharge standards before release In formulation development, consider blending with readily biodegradable surctants to reduce the overall environmental burden Establish emergency response plans for leaks to prevent accidental discharge into stormwater pipes or natural water bodies Notes If your application product needs to apply for green certifications such as China Environmental Labeling (Ten-ring Certification) or EU Ecolabel, this product may not meet the biodegradability index requirements When exporting to the EU market, confirm compliance with relevant REACH regulations and SVHC candidate list requirements

Question 5

What are the advantages of 600P-85% tristyrylphenol polyoxyethylene ether phosphate compared to other similar products?

Accepted Answer

600P-85% possesses the dual characteristics of "nonionic backbone + anionic phosphate ester group" among similar tristyrylphenol polyoxyethylene ether series products, with an active content ≥85%, showing outstanding performance in electrolyte tolerance, emulsification efficiency, low foaming properties, and formulation compatibility. Detailed Explanation Compared to the nonionic products in the same tristyrylphenol polyoxyethylene ether series in the Guoli Chemical database ( such as agricultural emulsifier 600, 600-1, 600-2, etc. ), the greatest differentiating advantage of 600P-85% lies in the introduction of phosphate anionic groups into its molecular structure. While ordinary 600 series products are pure nonionic surctants, 600P-85%, after phosphation modification, combines the dual properties of nonionic surctants (excellent emulsification and dispersion abilities) and anionic surctants (strong electrolyte tolerance, excellent wetting and spreading performance), demonstrating stronger intercial control capabilities in complex formulation systems. Its HLB value is approximately 12.5, lling within a range with good versatility for oil-water emulsification, and the reasonable ratio of monoester content 40%~60% and diester content 20%~40% achieves a good balance between emulsification efficiency and stability. Compared to the anionic product in the same series, XPO-5 tristyrylphenol polyoxyethylene ether ammonium sulte, 600P-85% adopts a phosphate group which has better thermal stability and hydrolysis resistance than the sulte group, making it particularly suitable for high-temperature operating environments (such as high-temperature leveling in textiles, downhole operations in oil fields, etc.). In addition, the free phosphoric acid content of 600P-85% is ≤0.5% (calculated as H₃PO₄), much lower than general industrial phosphate ester products, effectively reducing the risk of corrosion to metal equipment, while also playing a synergistic role of emulsification and rust prevention in metalworking fluids, an additional function that is difficult for ammonium sulte type products to achieve. From the perspective of application breadth, the critical micelle concentration (CMC) of 600P-85% is only 0.01%~0.05%, and the surce tension can be reduced to 30~35 mN\/m (1% aqueous solution), meaning it can exhibit high intercial activity at low usage concentrations, with prominent economic efficiency. Meanwhile, its low to medium foaming characteristics are significantly superior to the high foaming tendency of conventional anionic surctants, offering greater practical value in scenarios with strict foam control requirements, such as industrial cleaning and textile dyeing and printing. In terms of formulation compatibility, 600P-85% can be flexibly compounded with nonionic, anionic, cationic, and amphoteric surctants, with a scope r exceeding that of ordinary single ionic type products.

Question 8

How to use 600P-85% tristyrylphenol polyoxyethylene ether phosphate? What is the recommended dosage?

Accepted Answer

600P-85% has no fixed dosage standard. It should be added during the acid or alkali adjustment stage of the formulation, and the optimal amount should be determined through gradient tests. Detailed Explanation 600P-85% tristyrylphenol polyoxyethylene ether phosphate is an anionic surctant with high active matter content (≥85%), appearing as a light yellow to yellow high-viscosity liquid. Its unique phosphate ester structure imparts both nonionic and anionic surctant characteristics, with an HLB value of approximately 12.5. It is readily soluble in water and various organic solvents, and is a low-to-medium foaming product. In terms of usage, it is recommended to add this product during the acid or alkali adjustment stage of formulation development, when the pH of the system has not yet been finalized, allowing the phosphate ester groups to fully disperse and participate in intercial regulation. After addition, thorough stirring and mixing are required to ensure complete dissolution or emulsification in the system. Due to the varying requirements for emulsification, dispersion, wetting, and other properties in different application scenarios, Guoli Chemical officially recommends determining the optimal addition ratio through gradient tests, while optimizing synergy with other auxiliaries (such as other nonionic surctants, thickeners, antifreeze agents, etc.). This product contains 40%–60% mono-phosphate ester, 20%–40% di-phosphate ester, and ≤0.5% free phosphoric acid. The pH of a 1% aqueous solution is 2.0–3.5, indicating acidity, so neutralization adjustment is necessary if the formulation system is alkaline.

With a unique molecular structure of "multi-aromatic ring lipophilic backbone + polyoxyethylene chain + phosphate ester group," it combines the dual characteristics of nonionic and anionic surctants, exhibiting excellent intercial control ability in complex systems. The product has an HLB value of 12.5, belonging to a hydrophilic emulsifying dispersant, easily soluble in water and various organic solvents. Its phosphate ester structure endows the product with excellent electrolyte and hard water resistance, maintaining stable activity in high-salt systems. The foam properties range from low to moderate foam, making it more suitable than traditional anionic surctants for industrial operations requiring foam control. It also has good formulation compatibility and can be compounded synergistically with nonionic, anionic, cationic, and amphoteric surctants.
