Description

Polyglyceryl-3 Cetyl Ether is a high-purity, non-ionic surfactant and emollient derived from renewable resources, offering excellent skin compatibility and mildness. Its primary value lies in its ability to provide stable emulsification, rich texture, and effective moisturization in demanding personal care formulations. This makes it an essential ingredient for manufacturers in the cosmetics and personal care industry seeking to develop premium skin creams, lotions, sunscreens, and color cosmetics with a luxurious feel.

Application

• Primary Emulsifier in oil-in-water (O/W) systems for creams and lotions.
• Co-emulsifier & Stabilizer to enhance the texture and long-term stability of cosmetic emulsions.
• Skin Conditioning Agent in moisturizers, anti-aging serums, and body butters for a smooth, non-greasy afterfeel.
• Viscosity Modifier to build rich, creamy consistencies in personal care products.
• Base Ingredient in sunscreen formulations, helping to stabilize UV filters.
• Key Component in makeup products like foundations and BB creams for improved spreadability and wear.
• Hair Care Conditioner in conditioners and hair masks to impart softness and manageability.
• Pharmaceutical Ointments as a non-irritating emollient base for topical drug delivery systems.
