Accepted Answer

Tristyrylphenol Polyoxyethylene Ether 600-1 is a low-toxicity, environmentally friendly, and widely used high-performance nonionic surctant, excelling in emulsifying power, safety, and environmental friendliness. Detailed Description The greatest advantage of Tristyrylphenol Polyoxyethylene Ether 600-1 lies in its excellent safety and environmental performance. Compared to many similar products on the market, its toxicological profile is outstanding: oral LD50 for rats is greater than 5000 mg/kg, classifying it as a low-toxicity substance; skin irritation index is 0.0, completely non-irritating; and the 28-day biodegradation rate exceeds 60%, making it an easily biodegradable and environmentally friendly product. This characteristic of "high efficiency and low toxicity" makes it more friendly to operators and end users in fields such as pesticides and textiles, where usage is high and contact with the human body is frequent. In terms of application performance, the product's intercial activity and chemical stability are also superior to most general-purpose nonionic surctants. Thanks to its unique "tristyryl" macromolecular hydrophobic head and low EO addition number (n≈1), it possesses strong lipophilicity and a low HLB value (approximately 6), enabling efficient emulsification of various pesticides such as organophosphates and organochlorines, with high compatibility with "problematic oil phases" that are difficult to emulsify. At the same time, it exhibits strong stability against acids, alkalis, and hard water, and is not easily hydrolyzed, ensuring reliable performance in complex formulation systems. In contrast, some bio-based or common tty alcohol ether products often experience significant activity decline under harsh conditions. Additionally, this product combines low foaming and strong wetting penetration dual characteristics, which offers great advantages in applications. In certain industrial cleaning and textile processing, excessive foam is a serious process obstacle, while this product is inherently low-foaming, eliminating the need for additional defoamers. Meanwhile, its surce tension is about 35 mN/m, significantly enhancing the spreading ability of liquids on solid surces, allowing active ingredients to quickly penetrate the target surce. In scenarios such as paint wetting and pesticide spreading, it achieves the ideal effect of "sufficient wetting without foaming," which is difficult for many traditional NP series or AEO series surctants to achieve simultaneously.

What are the physicochemical and technical parameters of tristyrylphenol polyoxyethylene ether 600-1?

Accepted Answer

Tristyrylphenol polyoxyethylene ether 600-1 is a low-foaming nonionic surctant with an HLB value of approximately 6. At room temperature, it appears as a light yellow to brownish yellow liquid or paste, with strong lipophilicity and stable chemical properties. All core indicators meet the high-purity industrial standards. Detailed Description Tristyrylphenol polyoxyethylene ether 600-1 (CAS: 99734-09-5) is a nonionic surctant with a molecular weight of approximately 449. Its molecular structure has a low ethylene oxide addition number (n≈1), resulting in strong lipophilicity – it is readily soluble in oils and organic solvents but only dispersible in water. The product has an extremely high active content, with solid content and active substance content both ≥99%, free alcohol content controlled below 1%, and very few impurities. In terms of physical form, it has a low melting point (≤0°C). At room temperature (25°C), it appears as a light yellow to brownish yellow viscous liquid or semi-solid paste with a density of 1.05 g/cm³. Its acid-base properties are mild; the pH of both 1% and 5% aqueous solutions ranges from 5.0 to 7.0, near neutral, showing good compatibility with other components in the formulation system. The surce tension is approximately 35 mN/m, indicating good intercial activity. In terms of weathering resistance and stability, the product has a flash point above 200°C, does not undergo dangerous decomposition reactions under room temperature storage conditions, and is chemically stable. However, it should be noted that the product is not resistant to strong alkaline environments; avoid combining with high-concentration strong alkaline substances during formulation design. Additionally, its cloud point ranges from 45 to 55°C, and attention should be paid to the effect of temperature on phase behavior during use.

It is particularly suitable as an emulsifier monomer in pesticide emulsifiable concentrate systems and works better when combined with anionic emulsifiers (such as the agricultural emulsifier 500# series). In the coatings and inks industry, its low acid value and low iodine value mean minimal interference with the pigment system; it will not affect the color of the coating due to self-oxidation and discoloration. Due to its relatively low cloud point (45~55°C), attention should be paid to controlling the operating temperature in industrial cleaning or textile printing and dyeing processes that require heating, to avoid the surctant separating from the aqueous phase and losing efficacy when the temperature exceeds the cloud point. Its low-foaming property provides significant advantages in dynamic cleaning scenarios such as circulating spraying and high-pressure spraying. Precautions Strong alkali contraindication: This product is not resistant to strong alkalis. If alkaline components need to be added to the formulation, perform compatibility pre-tests or replace with alkali-resistant surctants. Temperature control: The recommended usage and storage temperature should be below 45°C to avoid approaching the cloud point and affecting dispersion performance. For long-term storage, keep sealed in a cool, dry place away from strong oxidizers and strong acids. Low-temperature fluidity: The product may solidify into a paste or semi-solid at temperatures below 0°C in winter. This is a normal physical change. Before use, slowly heat it in a warm water bath until it flows, then stir evenly; performance will not be affected. Parameter notes: Parameters such as kinematic viscosity, critical micelle concentration, permeability, and hygroscopicity have not been precisely measured. If detailed rheological or intercial chemical data are required, please contact the Guoli Chemical Technical Department for a special test report.
