Description

Polyethyleneglycol Diisostearate is a non-ionic surfactant and emollient ester derived from polyethylene glycol and isostearic acid. This versatile compound is valued for its excellent emulsifying, solubilizing, and skin-conditioning properties, making it a key ingredient in formulations requiring stability and a smooth, non-greasy feel. It is primarily utilized by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating stable emulsions and enhancing product texture.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary or co-emulsifier, solubilizer, and emollient in creams, lotions, sunscreens, and makeup products.
• Pharmaceutical Topicals: Used in ointments, creams, and gels as an emulsifying agent to ensure uniform drug delivery and a pleasant skin feel.
• Industrial Lubricants & Release Agents: Serves as a component in synthetic lubricants, mold release agents, and textile processing aids.
• Plasticizer & Dispersant: Functions as a plasticizer in polymer systems and a dispersing agent for pigments and fillers.
• Household & Institutional Products: Employed in the formulation of cleaning products, polishes, and waxes for its emulsifying power.
