Description

Polyglyceryl-3 Dilaurate is a cosmetic ingredient used primarily as an emulsifier and skin conditioner. It is the diester formed by the esterification of lauric acid with polyglycerol-3. This ingredient is favored for its ability to enhance the texture and stability of cosmetic formulations while providing moisturizing and skin-softening benefits.

Chemical Composition and Structure

The compound results from combining the multi-functional properties of polyglycerol-3 with lauric acid, a medium-chain fatty acid known for its lightweight and moisturizing properties. The diester structure of Polyglyceryl-3 Dilaurate enhances its emulsifying capabilities, making it effective in blending oil and water phases in cosmetic products.

Physical Properties

Polyglyceryl-3 Dilaurate typically appears as a clear, viscous liquid at room temperature. It is soluble in oils and has limited solubility in water, which makes it suitable for use in water-in-oil or oil-in-water emulsion systems. It lends a smooth, non-greasy feel to formulations.

Production Process

Synthesis: The diester is synthesized by reacting polyglycerol-3 with lauric acid. This reaction often involves a catalyst and controlled conditions to ensure complete esterification and high yield.
Purification: After synthesis, the compound undergoes purification to remove any unreacted materials and by-products. This step may involve distillation or filtration to achieve high purity.
Quality Control: Rigorous quality control tests are conducted on the final product, including assessments of purity, viscosity, and emulsification properties, to ensure compliance with cosmetic industry standards.

Applications

Cosmetic Products: Polyglyceryl-3 Dilaurate is widely used in creams, lotions, and makeup, where it helps to create stable emulsions and improves product texture and application experience.
Skin Care: It is employed in skincare formulations for its moisturizing properties, helping to keep the skin hydrated and soft.
Hair Care: Also used in hair care products such as conditioners and styling aids, it assists in detangling and smoothing hair without leaving a heavy residue.

Environmental and Safety Considerations

Polyglyceryl-3 Dilaurate is considered safe for use in cosmetic products and is generally well-tolerated by the skin. It is non-irritating and non-toxic, making it suitable for sensitive skin formulations. Being derived from renewable resources, it is viewed as an environmentally friendly choice. Proper usage within recommended concentrations is advised to ensure safety and 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.
