Description

Polyglyceryl-3 Soyate/Shea Butterate is an ester primarily used in the cosmetic industry as an emulsifier, skin conditioner, and moisturizer. This ester is formed from the reaction of Polyglycerin-3 with the fatty acids derived from Glycine Soja (Soybean) and Butyrospermum Parkii (Shea) Butter. This unique combination enhances the performance and sensory properties of various skincare and makeup formulations.

Chemical Composition and Structure

This ester combines the moisturizing and conditioning benefits of Polyglycerin-3, a polymer derived from glycerol, with the fatty acids of soybean and shea butter. Glycine Soja provides essential fatty acids, vitamins, and antioxidants, while Butyrospermum Parkii is known for its rich emollient properties and high content of vitamins A and E. The resultant ester is highly effective at stabilizing emulsions, providing a rich, creamy texture, and enhancing the overall feel of cosmetic products on the skin.

Physical Properties

Polyglyceryl-3 Soyate/Shea Butterate typically appears as a viscous, semi-solid substance that is clear to slightly yellowish in color. It is soluble in oils and has limited water solubility, making it ideal for use in both oil-in-water and water-in-oil emulsions, contributing to a rich, non-greasy feel.

Production Process

Esterification: The production involves the esterification of Polyglycerin-3 with the fatty acids derived from Glycine Soja and Butyrospermum Parkii. This process requires precise control of reaction conditions to ensure the formation of a stable and effective ester.
Purification: Following esterification, the product undergoes extensive purification to remove any unreacted materials and by-products, ensuring its purity and suitability for cosmetic use.
Quality Control: Rigorous testing is conducted on the final product to assess its purity, stability, and performance in various cosmetic formulations. These tests often include evaluations of emulsion stability, viscosity, and compatibility with other cosmetic ingredients.

Applications

Cosmetic Products: Widely used in creams, lotions, and serums where it acts as an effective emulsifier and skin conditioner, helping to blend and stabilize the mixture of oil and water components, and improving the product's overall texture and application properties.
Skin Care: Ideal for use in moisturizing and nourishing products, providing a smooth and enriching feel to the skin due to its emollient properties.
Makeup: Employed in foundations and lipsticks to enhance texture, spreadability, and wear, ensuring smooth and even coverage.

Environmental and Safety Considerations

Polyglyceryl-3 Soyate/Shea Butterate is considered safe for use in cosmetic products and is generally well-tolerated by the skin. It is non-irritating and suitable for all skin types, including sensitive skin. Proper use within recommended concentrations is essential to ensure safety and maximize effectiveness.

INCI

In cosmetic labeling, Polyglyceryl-3 Soyate/Shea Butterate is listed under its INCI name, reflecting its chemical identity as the ester of Polyglycerin-3 with the fatty acids of Glycine Soja (Soybean) and Butyrospermum Parkii (Shea) Butter, used for regulatory and commercial purposes in the cosmetics industry.


Surfactant - Emulsifying agent. Emulsions are thermodynamically unstable and are used to soothe or soften the skin and emulsify, so they need a specific, stabilising ingredient. This ingredient forms a film, lowers the surface tension and makes two immiscible liquids miscible. A very important factor affecting the stability of the emulsion is the amount of the emulsifying agent. Emulsifiers have the property of reducing the oil/water or water/oil interfacial tension, improving the stability of the emulsion and also directly influencing the stability, sensory properties and surface tension of sunscreens by modulating the filmometric performance.
