Description

4-o-β-D-Galactopyranosyl-D-Glucitol Stearate is a high-purity, non-ionic surfactant derived from lactose and stearic acid, combining the hydrophilic properties of a sugar with the lipophilic character of a fatty acid ester. This unique structure makes it an exceptionally mild and effective emulsifier, stabilizer, and conditioning agent, prized for its biocompatibility and skin-friendly profile. It is primarily sought after by manufacturers in the personal care, cosmetic, and pharmaceutical industries for formulating high-end, gentle products.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary or co-emulsifier in creams, lotions, and milky cleansers, providing stable emulsions with a luxurious, non-greasy feel.
• Skin Care Products: Valued for its mildness and skin-conditioning properties in sensitive skin formulations, baby care products, and moisturizers.
• Hair Care Products: Functions as an effective conditioner and emulsifier in shampoos, conditioners, and hair styling products, improving manageability and shine.
• Pharmaceutical Topicals: Used as an excipient in ointments, gels, and medicated creams where a non-irritating, stable emulsion base is required.
• Food-Grade Applications: Can serve as an emulsifier in certain food products, leveraging its origin from sugar and fatty acids (subject to specific grade and regulatory approval).
• Advanced Drug Delivery Systems: Investigated for use in lipid-based nano-carriers and microemulsions to enhance the solubility and bioavailability of poorly soluble active ingredients.
