Description

Laureth-4 Carboxylic Acid is a non-ionic surfactant and an important intermediate in the synthesis of anionic surfactants, specifically alkyl ether carboxylates (AEC). This compound matters for formulators seeking mild, high-foaming, and stable surfactants with excellent compatibility across a wide pH range. It is primarily needed by manufacturers in the personal care, home care, and industrial cleaning sectors for creating high-performance formulations.

Application

• Primary Intermediate: Key raw material for the production of Sodium Laureth-4 Carboxylate and other alkyl ether carboxylate salts.
• Personal Care Cleansers: Used in the manufacture of mild facial cleansers, shower gels, shampoos, and liquid soaps due to its excellent skin compatibility.
• Home & Institutional Cleaning: Formulated into high-foaming, low-irritation dishwashing liquids, all-purpose cleaners, and hard surface cleaners.
• Industrial & Institutional (I&I) Cleaners: Employed in formulations for vehicle washes, food processing plant cleaners, and dairy detergents where mildness and stability are required.
• Cosmetic Emulsification: Acts as a co-emulsifier and stabilizer in various cosmetic creams and lotions.
• Textile & Leather Processing: Serves as a wetting agent, emulsifier, and dispersant in auxiliary formulations for textile and leather treatment.
