Description

C8E3 CAS NO 19327-38-9 is a high-purity, non-ionic surfactant belonging to the alkyl polyglycol ether (CiEj) family, specifically octyl alcohol ethoxylate with three ethylene oxide units. This compound is valued for its excellent wetting, emulsifying, and dispersing properties in aqueous and non-aqueous systems. It is a critical raw material for formulators in the agrochemical, coatings, textile, and personal care industries seeking reliable performance and batch-to-batch consistency.

Application

• As a key wetting agent and emulsifier in agricultural formulations, including herbicides, insecticides, and fungicides.
• As a dispersant and stabilizer in pigment pastes, latex paints, and other coating systems.
• As an intermediate and surfactant in the synthesis of specialty chemicals and industrial cleaners.
• In textile processing as a scouring, leveling, or dyeing assistant.
• As a co-emulsifier and solubilizer in cosmetic and personal care products.
• In industrial and institutional (I&I) cleaning formulations for hard surface cleaning.
• In the paper and pulp industry as a deinking agent and process aid.
