Description

Trideceth-4 Carboxylic Acid is a high-purity, non-ionic surfactant intermediate derived from ethoxylated tridecyl alcohol. This compound is valued for its excellent emulsifying, dispersing, and mild surfactant properties, making it a versatile building block for specialty formulations. It is primarily used by manufacturers in the personal care, cosmetics, and industrial cleaning sectors seeking to enhance product performance and stability.

Application

• Primary Surfactant & Emulsifier in mild facial cleansers, shower gels, and shampoos.
• Key Intermediate for the synthesis of amphoteric and anionic surfactants (e.g., betaines, sarcosinates).
• Stabilizing Agent in cosmetic creams, lotions, and sun care products.
• Industrial Dispersant in agrochemical formulations and pigment preparations.
• Foam Booster & Viscosity Modifier in liquid soaps and detergents.
• Coupling Agent for fragrances and oils in aqueous systems.
