Description

Sodium Laureth-5 Carboxylate is a high-performance, mild anionic surfactant derived from ethoxylated lauryl alcohol. 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 critical ingredient for formulators in the personal care, home care, and industrial cleaning sectors seeking effective, skin-friendly, and biodegradable surfactant solutions.

Application

• Personal Care Cleansers: A primary surfactant in mild facial cleansers, shower gels, shampoos, and hand soaps, offering rich lather and low irritation.
• 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 hard surface cleaners due to its grease-cutting ability and compatibility with other ingredients.
• Industrial & Technical Cleaners: Employed in formulations for vehicle wash, dairy cleaners, and metal degreasers where high detergency and foam are required.
• Textile & Leather Processing: Acts as a wetting agent, scouring aid, and emulsifier in various processing baths.
