Description

Butanedioic Acid, 2,3-Dihydroxy- [R-(R*,R*)]-, C12-14-Branched And Linear Alkyl Esters is a high-purity, non-ionic surfactant and emollient derived from natural tartaric acid and renewable C12-14 fatty alcohols. This compound matters for formulators seeking a versatile, skin-friendly ingredient with excellent emulsifying, solubilizing, and conditioning properties. It is primarily needed by manufacturers in the personal care, cosmetic, and pharmaceutical industries for creating stable, elegant formulations.

Application

• Primary Emulsifier in cosmetic creams, lotions, and sun care products for creating stable oil-in-water emulsions.
• Skin Conditioning Agent and emollient, providing a smooth, non-greasy feel in moisturizers and serums.
• Solubilizer for fragrances, essential oils, and active ingredients in clear gels and aqueous formulations.
• Viscosity Modifier and stabilizer in surfactant-based systems like shampoos and body washes.
• Pharmaceutical Excipient used in topical drug delivery systems for its emulsifying and penetration-enhancing properties.
• Industrial Surfactant in specialty cleaning formulations and agrochemical adjuvants.
