POLYGLYCERYL-6 STEARATE.

Valuable CAS 95461-65-7 / SKIN CONDITIONING - EMOLLIENT

Polyglyceryl-6 Stearate is a multifunctional ester primarily recognized for its emulsifying properties, enabling the stable fusion of oil and water in cosmetic formulations. Beyond its role in product structure, it functions as a skin conditioning agent, delivering moisturization, softening the skin, and improving the uptake of other active ingredients. Its robust profile makes it a highly versatile component across a wide array of skincare and cosmetic products.

Science

Mechanism of Action

This non-ionic surfactant effectively acts as an emulsifier, facilitating the blend of immiscible oil and water phases to create stable emulsions. On the skin, Polyglyceryl-6 Stearate operates as an emollient and skin conditioning agent, contributing to a smoother and softer skin texture. It assists in maintaining the skin's moisture balance by forming a protective barrier and is noted for its capacity to enhance the penetration of active compounds into the skin's deeper layers, simultaneously improving product feel.

Stability

Polyglyceryl-6 Stearate effectively forms stable oil-in-water (O/W) emulsions within a pH range of 4.0 to 8.5. It exhibits excellent stabilization properties, even in challenging systems such as sun care formulations with high loads of water-soluble UV filters, insect repellents, electrolytes, urea, or ethanol. It demonstrates good compatibility with other substances and is resistant to salt and acid. For optimal stability, the product should be sealed and stored in cool, dry, and ventilated conditions due to its moisture absorption properties.
