Description

Polyglyceryl-3 Hydroxylauryl Ether is a cosmetic ingredient extensively used as an emulsifier, surfactant, and skin conditioner in a range of skincare and cosmetic products. It is synthesized by reacting 2-hydroxydodecyl alcohol with polyglycerin-3. This combination forms a unique compound that enhances the moisturizing, stability, and tactile properties of cosmetic formulations.

Chemical Composition and Structure

This compound combines the beneficial properties of 2-hydroxydodecyl alcohol, which is known for its emollient and skin-conditioning abilities, with polyglycerin-3, a polymer derived from glycerol known for its excellent moisture retention capabilities. The interaction between these components results in a polymer that is effective at stabilizing emulsions and improving the feel of skin care and makeup products on the skin.

Physical Properties

Polyglyceryl-3 Hydroxylauryl Ether typically appears as a viscous, clear to slightly yellowish liquid at room temperature. It is soluble in oils and has limited solubility in water, which makes it particularly useful in oil-based cosmetic formulations where it can enhance the product’s stability and provide a rich, moisturizing feel.

Production Process

Synthesis: The production of Polyglyceryl-3 Hydroxylauryl Ether involves the esterification of polyglycerin-3 with 2-hydroxydodecyl alcohol. This process requires precise control of reaction conditions to ensure the formation of a stable and effective polymer.
Purification: Following synthesis, the compound 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 consistency, stability, and performance in various cosmetic formulations. Tests often include evaluations of viscosity, emulsion stability, and compatibility with other cosmetic ingredients.

Applications

Cosmetic Products: Widely used in creams, lotions, and serums where it acts as an effective emulsifier and surfactant, helping to blend and stabilize the mixture of oil and water components, and improving the product's overall texture and application properties.
Skin Care: Ideal for use in moisturizing and hydrating products, providing a smooth and enriching feel to the skin due to its emollient properties.
Makeup: Employed in foundations and concealers to enhance their moisturizing properties and ensure smooth, even coverage.

Environmental and Safety Considerations

Polyglyceryl-3 Hydroxylauryl Ether 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 - 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.
