Description

Laureth-3 Carboxylic Acid is a nonionic surfactant and emulsifying agent derived from lauric acid and ethylene oxide. This compound is valued for its excellent surface-active properties, mildness, and good compatibility with a wide range of cosmetic and industrial formulations. It is primarily utilized by manufacturers in the personal care, home care, and specialty chemical industries as a key ingredient for creating stable emulsions and enhancing product performance.

Application

• Primary Emulsifier in cosmetic creams, lotions, and sun care products.
• Foam Booster and Stabilizer in mild cleansing formulations such as facial washes and shower gels.
• Co-emulsifier and Dispersing Agent in household and industrial cleaning products.
• Intermediate for the synthesis of more complex ester-based surfactants.
• Wetting Agent in textile processing and agrochemical formulations.
• Additive in metalworking fluids and lubricants for its emulsifying and anti-corrosion properties.
