Description

Polyglyceryl-5 Stearate is a non-ionic, multifunctional surfactant derived from the esterification of polyglycerol-5 with stearic acid. This compound is highly valued for its excellent emulsifying, stabilizing, and conditioning properties, making it a versatile ingredient in sophisticated formulations. It is primarily used by manufacturers in the personal care, cosmetics, and food industries seeking effective, mild, and compliant ingredients.

Application

• Cosmetic & Personal Care Emulsions: Acts as a primary or co-emulsifier in creams, lotions, and sunscreens, providing stable oil-in-water (O/W) systems.
• Hair Care Products: Used in conditioners and styling products for its emulsifying and hair-conditioning benefits, improving manageability and feel.
• Skin Care Formulations: Functions as an effective stabilizer and emollient in moisturizers and anti-aging products, enhancing skin texture.
• Food Industry: Serves as an emulsifier and stabilizer in certain food products, contributing to texture and shelf-life stability.
• Pharmaceutical Topicals: Employed in ointments, creams, and medicinal emulsions as a non-irritating emulsifying agent.
• Industrial Applications: Can be utilized as a dispersing agent or emulsifier in various specialty chemical and agrochemical formulations.
