Description

Caprylyl Trimethicone CAS NO 187593-69-7 is a high-performance organomodified silicone fluid, specifically a caprylyl-substituted trimethylsiloxy-terminated polydimethylsiloxane. This unique structure provides exceptional emolliency, spreading properties, and compatibility with a wide range of cosmetic oils and esters. It is a key ingredient for formulators seeking to enhance the sensory profile and performance of personal care products. Primary users include manufacturers in the cosmetics, skincare, and haircare industries.

Application

• As a volatile emollient and sensory enhancer in facial foundations, primers, and color cosmetics.
• To impart a dry, silky, non-greasy afterfeel in sun care products, moisturizers, and body lotions.
• As a conditioning and glossing agent in hair care products like serums, conditioners, and styling creams.
• To improve spreadability and texture in anhydrous formulations such as lipsticks, balms, and makeup removers.
• As a solubilizer and carrier for active ingredients and fragrances in various cosmetic systems.
• Used in water-resistant and long-wear formulations due to its hydrophobic nature.
• To reduce the whitening effect and tackiness of sunscreen actives and other film-forming agents.
