Description

Diisostearyl Malate is a high-purity, non-greasy emollient ester derived from natural fatty alcohols and malic acid. This versatile ingredient is prized for its exceptional skin feel, providing a smooth, silky texture without tackiness or residue. It serves as a key functional component for formulators in the personal care and cosmetics industries, where superior sensory properties and product stability are paramount.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, sunscreens, and decorative cosmetics.
• Lipstick & Lip Gloss: Imparts excellent gloss, spreadability, and a non-sticky feel in lip products.
• Hair Care Products: Used in conditioners, serums, and styling products to reduce frizz, enhance shine, and improve combability.
• Color Cosmetics: Functions as a pigment dispersant and binder in foundations, eyeshadows, and blushes for smooth application and even color payoff.
• Skin Care Emulsions: Enhances the stability and luxurious texture of O/W (oil-in-water) and W/O (water-in-oil) emulsions.
• Sunscreen & SPF Formulations: Improves the spreadability of UV filters and contributes to a pleasant, non-greasy after-feel.
