Polyglyceryl-3 Triolivate is a cosmetic ingredient that acts as an emulsifier and skin conditioner. It is the triester formed by the reaction of polyglycerol-3 with oleic acid, derived from olive oil. This ingredient is primarily used to enhance the stability, texture, and moisturizing effect of cosmetic formulations.

Chemical Composition and Structure

This ester combines the emollient properties of polyglycerol-3 with the nourishing qualities of oleic acid, a monounsaturated fatty acid typical of olive oil. The result is a molecule that not only stabilizes emulsions but also enhances the absorption and effectiveness of moisturizing ingredients on the skin.

Physical Properties

Polyglyceryl-3 Triolivate typically appears as a viscous, clear to slightly yellow liquid. It is soluble in oils and has good compatibility with various types of cosmetic ingredients, facilitating the formation of stable and homogeneous emulsions.

Production Process

Synthesis: The triester is synthesized through an esterification process where polyglycerol-3 reacts with oleic acid. This reaction is usually facilitated by a catalyst and conducted under controlled temperature conditions to ensure efficient ester bond formation.
Purification: After synthesis, the product is purified through techniques such as distillation or filtration to eliminate impurities and residual reagents.
Quality Control: The finished product undergoes rigorous testing to verify its purity, stability, and functionality, ensuring it meets the quality standards for cosmetic use.

Applications

Cosmetic Products: Used in creams, lotions, and other skincare products, Polyglyceryl-3 Triolivate helps to emulsify and stabilize formulations, improving the feel on the skin and the longevity of the product.
Skin Care: Thanks to its moisturizing and nourishing properties, it is particularly suitable for products aimed at dry or sensitive skin, where it helps to maintain hydration and protect the skin barrier.
Makeup Products: Also employed in makeup formulations to improve the spreadability and durability of products on the skin.

Environmental and Safety Considerations

Polyglyceryl-3 Triolivate is considered safe for use in cosmetic products and is generally well-tolerated by the skin. It is derived from renewable resources, making it a sustainable choice for cosmetic formulations. It is important to use this ingredient within the recommended concentrations to avoid possible skin sensitivities.

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.
