Description

C18E6 CAS NO 2420-29-3 is a high-purity, non-ionic surfactant belonging to the polyethylene glycol alkyl ether family, specifically hexaethylene glycol monooctadecyl ether. This compound is valued for its excellent emulsifying, wetting, and solubilizing properties, making it a critical component in the formulation of high-performance industrial and specialty chemical products. It is primarily sought after by manufacturers in the agrochemical, coatings, personal care, and pharmaceutical industries for its ability to stabilize complex mixtures and enhance product efficacy.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticides, herbicides, and fungicides to improve sprayability and active ingredient delivery.
• Coatings and Inks: Used as a wetting agent and flow control additive to enhance pigment dispersion and surface finish quality.
• Personal Care Products: Functions as a non-ionic emulsifier and solubilizer in creams, lotions, and other cosmetic formulations.
• Pharmaceutical Excipient: Employed as a solubilizing agent and stabilizer in drug delivery systems and topical preparations.
• Industrial Cleaners: Serves as a surfactant in heavy-duty degreasers and cleaning concentrates for its effective oil and grease removal.
• Textile Processing: Utilized as a leveling and scouring agent in dyeing and finishing processes.
