Tristyrylphenol Polyoxyethylene Ether 600-1 (also known as Agricultural Emulsifier 600#-1, Emulsifier 600#-1, CAS No.: 99734-09-5) appears as a light yellow to brownish yellow viscous liquid or semi-solid. With its unique molecular structure design—combining tristyrylphenol with polyoxyethylene ether—this product exhibits excellent interfacial activity in various demanding formulation systems and is widely used in pesticide formulations, coatings and inks, textile dyeing and printing, and industrial cleaning.
As a nonionic surfactant, its greatest feature is "all-around balance"—it possesses strong emulsifying and dispersing abilities, effectively reducing interfacial tension, and shows excellent compatibility with organophosphorus and organochlorine pesticides; it also maintains good activity under acidic, alkaline, and high-hardness water conditions, is not easily hydrolyzed or deactivated, and has strong compatibility. At the same time, it exhibits low foaming characteristics, which is particularly valuable in industrial circulating cleaning and spraying applications.
In terms of safety and environmental protection, this product also performs outstandingly: it is classified as a non-hazardous material, has low toxicity (rat oral LD50 > 5000 mg/kg), is non-irritating to the skin, is readily biodegradable (28-day biodegradation rate > 60%), meets the positioning of an environmentally friendly product, and is convenient for storage, transportation, and use.
