Description

Peg-4 Polyglyceryl-2 Distearate CAS NO 72828-11-6 is a non-ionic, high-performance surfactant and emulsifier derived from polyglycerol and stearic acid. This compound is valued for its excellent stability, skin compatibility, and ability to form stable oil-in-water emulsions across a wide pH range. It is primarily sought after by formulators in the personal care, cosmetics, and pharmaceutical industries for creating creams, lotions, and other topical preparations with a luxurious, non-greasy feel.

Application

• Primary emulsifier and co-emulsifier in cosmetic and personal care formulations such as creams, lotions, and sunscreens.
• Stabilizing agent for oil-in-water (O/W) emulsions, providing enhanced texture and long-term shelf stability.
• Key ingredient in makeup products, including foundations and BB creams, for smooth application and even coverage.
• Used in pharmaceutical topical ointments and dermatological preparations for its mildness and emulsifying properties.
• Functional additive in hair care products like conditioners and styling creams to improve manageability and shine.
• Base material for the production of specialized emulsifiers with tailored HLB values for specific industrial applications.
