Description

Peg-27 Lanolin CAS NO 8051-81-8 is a non-ionic surfactant and emollient derived from lanolin, chemically modified with polyethylene glycol (PEG) chains to enhance its water solubility and skin-feel properties. This modification is critical for formulators seeking the rich, occlusive benefits of lanolin in more elegant, easy-to-process, and stable cosmetic and pharmaceutical emulsions. It is an essential ingredient for manufacturers in the personal care, topical pharmaceutical, and high-end cosmetic industries who require a reliable, multifunctional conditioning agent.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier, superfatting agent, and emollient in creams, lotions, and hair conditioners, providing a soft, non-greasy afterfeel.
• Topical Pharmaceutical Ointments: Used as a base ingredient to improve the spreadability, stability, and skin absorption of active pharmaceutical ingredients (APIs).
• Baby Care Products: A key component in diaper rash creams and baby lotions due to its excellent skin compatibility and protective barrier properties.
• Lip Care Products: Provides long-lasting moisture and a protective film in lip balms, sticks, and glosses.
• Sun Care Products: Enhances water resistance and skin substantivity in sunscreens while contributing to a smooth application.
• Color Cosmetics: Improves pigment dispersion and application smoothness in foundations, mascaras, and other makeup products.
• Industrial Emulsions & Polishes: Serves as an emulsifier and lubricant in specialty industrial formulations like leather conditioners and furniture polishes.
