Description

L-Glutamic Acid, n-(1-Oxotetradecyl)-, Potassium Salt (9Ci) is a potassium salt derivative of a long-chain acylated glutamic acid, offering enhanced solubility and stability for specialized formulations. This compound is valued for its role as a high-performance surfactant and emulsifying agent, providing excellent surface activity and compatibility in complex systems. It is primarily needed by manufacturers in the personal care, cosmetics, and specialty chemical industries seeking advanced ingredients for stable emulsions and mild cleansing products.

Application

• Primary Surfactant in mild facial cleansers, shower gels, and shampoos.
• Emulsifying Agent for stabilizing oil-in-water (O/W) emulsions in creams and lotions.
• Foam Booster and Stabilizer in personal care and cosmetic formulations.
• Key Ingredient in high-end skincare products requiring gentle yet effective cleansing.
• Industrial Surfactant for specialty cleaning and wetting applications.
• Intermediate for the synthesis of more complex amphoteric or anionic surfactants.
