Description

1,2,3-Propanetriyl Triisooctadecanoate is a high-purity synthetic ester, specifically the triester of glycerol with isostearic acid. This compound is valued for its excellent emollient properties, oxidative stability, and compatibility with a wide range of cosmetic and personal care ingredients. It serves as a key functional ingredient for formulators in the cosmetics, personal care, and pharmaceutical industries seeking superior skin feel and product performance.

Application

• Cosmetic & Personal Care Emollient: Primary function as a non-greasy, fast-spreading emollient in creams, lotions, and sun care products.
• Skin Care Formulations: Used in anti-aging serums, moisturizers, and body butters to enhance skin softness and provide a silky afterfeel.
• Makeup Products: Imparts smooth application and improved pigment dispersion in foundations, lipsticks, and color cosmetics.
• Hair Care Conditioner: Acts as a conditioning agent in shampoos, conditioners, and hair masks to reduce frizz and improve manageability.
• Pharmaceutical Topicals: Employed as a base or carrier in ointments, creams, and topical drug delivery systems.
• High-Performance Lubricants: Used in specialty synthetic lubricants and release agents due to its stability.
