Description

Polyglyceryl-4 Distearate is a diester of Polyglycerin-4 with Stearic Acid. This compound is widely used in the cosmetic industry for its emulsifying, conditioning, and moisturizing properties, enhancing various skincare and haircare products.

Chemical Composition and Structure

Polyglyceryl-4 Distearate combines the emollient and conditioning properties of Polyglycerin-4 with the stabilizing and emulsifying properties of Stearic Acid. The resulting product improves the stability of emulsions and provides excellent moisturizing and conditioning benefits for the skin and hair.

Physical Properties

Polyglyceryl-4 Distearate typically appears as a viscous or semi-solid substance, with a color ranging from white to pale yellow. 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. It contributes to a rich and non-greasy texture, enhancing the sensory experience of cosmetic products.

Production Process

Esterification: The production involves the esterification of Polyglycerin-4 with Stearic Acid. This process requires precise control of reaction conditions to ensure the formation of stable and effective esters.
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 for its emulsifying and moisturizing properties, improving the texture and feel of the product on the skin.
Skin Care: Ideal for moisturizing and nourishing products, providing a smooth and enriching feel to the skin due to its emollient properties.
Hair Care: Incorporated into conditioners and hair masks, contributing to the nourishment, softening, and conditioning of the hair.

Environmental and Safety Considerations

Polyglyceryl-4 Distearate 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


Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
