Description

Polyglyceryl-4 Triisostearate is the triester formed from the reaction of Isostearic Acid and Polyglycerin-4. 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 Triisostearate combines the beneficial properties of Isostearic Acid, known for its excellent emollient and conditioning characteristics, with Polyglycerin-4, which provides superior emulsifying and hydrating capabilities. The resulting triester improves the stability of emulsions and offers superior conditioning and moisturizing benefits for the skin and hair.

Physical Properties

Polyglyceryl-4 Triisostearate typically appears as a viscous or semi-solid substance, with a color ranging from clear 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, non-greasy texture, enhancing the sensory experience of cosmetic products.

Production Process

Esterification: The production involves the esterification of Polyglycerin-4 with Isostearic Acid. This process requires precise control of reaction conditions to ensure the formation of a stable and effective triester.
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 Triisostearate 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


Surfactant - Foam booster. It has the effect of introducing gas bubbles into the water and affects the cleaning process by helping to spread the cleanser. Since sebum has an inhibiting effect on the bubble, more foam is produced in the second shampoo.
