Tri(Polyglyceryl-3/Lauryl) Hydrogenated Trilinoleate is a specialized cosmetic ingredient primarily used as an emulsifying, stabilizer, and viscosity enhancer in various skincare and makeup products. It is a mixed ester formed by the reaction of Trilinoleic Acid with Polyglycerin-3 and Lauryl Alcohol, undergoing a hydrogenation process that enhances its oxidative stability and increases its melting point. This makes it particularly effective in formulations requiring a richer, more substantial texture.

Chemical Composition and Structure

This ingredient uniquely combines the moisturizing and barrier-enhancing properties of Trilinoleic Acid, derived from linoleic acid-rich vegetable oils, with the emulsifying and hydrating properties of Polyglycerin-3. Lauryl Alcohol serves as a co-emollient, enhancing the overall sensory attributes of the ester. The hydrogenation of the trilinoleate part increases its stability against oxidation, making it more suitable for longer shelf life cosmetic products.

Physical Properties

Tri(Polyglyceryl-3/Lauryl) Hydrogenated Trilinoleate appears as a waxy solid at room temperature, typically pale yellow in color. It is soluble in oils and has limited solubility in water, making it ideal for use in oil-based formulations and water-in-oil emulsions.

Production Process

Esterification and Hydrogenation: The production process begins with the esterification of Trilinoleic Acid with Polyglycerin-3 and Lauryl Alcohol. This complex esterification is followed by hydrogenation, which solidifies the ester and enhances its stability and usability in various cosmetic applications.
Purification: Following synthesis, the product undergoes thorough purification to ensure removal of any unreacted materials and by-products, achieving high purity and quality.
Quality Control: Extensive quality control testing is conducted on the final product to assess its consistency, stability, and efficacy across a range of cosmetic formulations. These tests typically include evaluations of melting point, viscosity, and compatibility with other cosmetic ingredients.

Applications

Cosmetic Products: Extensively used in lip care products like lipsticks and balms where it provides substantial emolliency, improves product stability, and contributes to a smooth, creamy texture.
Skin Care: Ideal for use in creams, lotions, and body butters, where it enhances product viscosity and provides a rich, moisturizing feel to the skin.
Makeup: Employed in makeup formulations such as foundations and concealers to improve texture, spreadability, and long-lasting wear, ensuring a flawless application.

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 a compound derived from naturally occurring fatty acids and alcohols, it is viewed as a relatively environmentally friendly ingredient. Proper use within recommended concentrations is essential for ensuring safety and maximizing 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.
