Description

Peg-8 Stearate is a non-ionic surfactant synthesized from polyethylene glycol and stearic acid, functioning as an effective emulsifier, opacifier, and viscosity modifier. Its balanced hydrophilic-lipophilic properties make it a versatile ingredient for creating stable, high-quality formulations. This compound is essential for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking reliable performance and skin-friendly characteristics.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and opacifying agent in creams, lotions, and hair conditioners.
• Pharmaceutical Topicals: Used as an excipient in ointments, creams, and topical emulsions for its stabilizing and non-irritating properties.
• Industrial Emulsions: Serves as an emulsifier and dispersant in textile processing aids, leather finishing products, and polishes.
• Household & Institutional Products: Employed in the production of liquid soaps, detergents, and cleaning formulations for enhanced viscosity and stability.
