Description

Sodium Capryleth-9 Carboxylate is a high-performance, mild anionic surfactant derived from caprylic acid and ethoxylated to enhance its water solubility and compatibility. This compound is valued for its excellent foaming, cleansing, and emulsifying properties, even in hard water and across a wide pH range. It is a key ingredient for formulators in the personal care, home care, and industrial cleaning sectors seeking effective, skin-friendly surfactants.

Application

• Personal Care Cleansers: A primary surfactant in facial cleansers, shower gels, shampoos, and hand soaps for its mildness and rich lather.
• Cosmetic Emulsions: Used as an emulsifier and stabilizer in lotions, creams, and makeup removers.
• Household & Institutional Cleaners: An effective component in liquid dish soaps, all-purpose cleaners, and floor care products.
• Industrial & Technical Cleaners: Employed in formulations for vehicle wash, dairy cleaners, and metal degreasers.
• Textile Processing: Functions as a wetting agent, scouring aid, and emulsifier in textile auxiliaries.
