Description

C12-13 Pareth-5 Carboxylic Acid is a high-purity, non-ionic surfactant intermediate derived from ethoxylated C12-13 fatty alcohols. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a critical raw material for formulating high-performance industrial and personal care products. It is primarily sought by manufacturers in the detergent, cosmetic, textile, and agrochemical industries for the production of anionic surfactants, specialty cleansers, and emulsion stabilizers.

Application

• Primary raw material for the synthesis of anionic surfactants (e.g., ether carboxylates) used in liquid soaps, shampoos, and shower gels.
• Key intermediate in the production of industrial and institutional (I&I) cleaners and degreasers, offering enhanced soil removal and foam control.
• Emulsifier and stabilizer in agricultural formulations such as pesticide and herbicide emulsions.
• Wetting and dispersing agent in textile processing aids and dyeing auxiliaries.
• Co-emulsifier in cosmetic and personal care products, including creams, lotions, and makeup removers.
• Intermediate for manufacturing specialty surfactants used in oilfield chemicals and enhanced oil recovery.
• Component in metalworking fluids and industrial lubricants for improved surface wetting.
