Tri(Polyglyceryl-3/Lauryl) Hydrogenated Trilinoleate is an innovative cosmetic ingredient widely utilized as an emulsifier, thickener, and skin-conditioning agent in a variety of skincare and makeup products. This mixed ester is produced by reacting Trilinoleic Acid with Polyglycerin-3 and Lauryl Alcohol, resulting in a compound that enhances the texture, stability, and moisturizing properties of cosmetic formulations.

Chemical Composition and Structure

This complex ester combines the skin-nourishing benefits of Trilinoleic Acid, derived from linoleic acid-rich oils, with the moisturizing effects of Polyglycerin-3 and the emollient properties of Lauryl Alcohol. The hydrogenation process involved in its synthesis improves the oxidative stability and increases the melting point, making it particularly effective in formulations requiring a richer, more substantial texture.

Physical Properties

Tri(Polyglyceryl-3/Lauryl) Hydrogenated Trilinoleate typically appears as a thick, waxy solid at room temperature. It is soluble in oils and has limited water solubility, making it ideal for water-in-oil emulsions and other oil-based cosmetic products where enhanced viscosity and stability are desired.

Production Process

Esterification and Hydrogenation: The production process involves the esterification of Trilinoleic Acid with Polyglycerin-3 and Lauryl Alcohol, followed by hydrogenation. This carefully controlled chemical reaction ensures the formation of a stable, high-quality ester with desired functional properties.
Purification: After synthesis, the product undergoes extensive purification to remove any unreacted starting 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, consistency, and efficacy in various cosmetic formulations. These tests typically include evaluations of melting point, viscosity, and emulsion stability.

Applications

Cosmetic Products: Extensively used in lipsticks, balms, and other lip care products, where it provides excellent emolliency, enhances product structure, and contributes to a smooth, creamy texture.
Skin Care: Ideal for use in rich creams, lotions, and body butters, as it effectively conditions the skin, providing lasting hydration and improving skin barrier function.
Makeup: Employed in foundations and concealers to improve product consistency, spreadability, and adherence, ensuring a flawless, long-lasting finish.

Environmental and Safety Considerations

Tri(Polyglyceryl-3/Lauryl) Hydrogenated Trilinoleate 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. As it incorporates naturally derived ingredients, it is viewed as an environmentally friendly choice. Proper use within recommended concentrations is crucial to ensure safety and maximize effectiveness.

INCI


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.

Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
