Description

Polyglyceryl-3 Lactate/Laurate is a cosmetic ingredient that acts as an emulsifier and skin conditioner. It is a monoester formed from the reaction of polyglycerol-3 with a mixture of lactic and lauric acids. This ingredient is commonly used in various cosmetic formulations to enhance texture, stabilize emulsions, and provide moisturizing and skin-softening benefits.

Chemical Composition and Structure

This compound combines the hydrophilic properties of polyglycerol-3 with the fatty acid characteristics of lauric acid and the hydrating properties of lactic acid. The resulting monoester is effective in improving the solubility of other cosmetic ingredients and helps in the formation of stable, creamy emulsions.

Physical Properties

Polyglyceryl-3 Lactate/Laurate typically appears as a clear to slightly yellowish viscous liquid. It is soluble in water and some oils, making it versatile for use in both aqueous and anhydrous cosmetic formulations. It has good skin compatibility and contributes to a pleasant skin feel.

Production Process

Synthesis: The ester is synthesized through an esterification process where polyglycerol-3 is reacted with a blend of lactic and lauric acids. This usually involves heating the reactants in the presence of a catalyst to promote ester linkage formation.
Purification: After synthesis, the product is purified through filtration and distillation processes to ensure the removal of unreacted acids and other impurities.
Quality Control: The final product undergoes a series of quality control tests, such as HPLC and viscosity measurements, to ensure it meets the required purity and performance specifications.

Applications

Cosmetic Products: Used in creams, lotions, sunscreens, and makeup foundations, where it serves as an emulsifier to blend oil and water phases effectively and as a moisturizer to improve skin hydration.
Skin Care: Its inclusion in skin care products helps to soften the skin and maintain its natural moisture barrier.
Personal Care Products: Also found in personal care items such as shampoos and conditioners, where it aids in the manageability and softness of hair.

Environmental and Safety Considerations

Polyglyceryl-3 Lactate/Laurate is considered safe for use in cosmetics and personal care products, with a good safety profile in terms of skin irritation and sensitivity. It is biodegradable, which reduces environmental impact. However, like all cosmetic ingredients, it should be used within the recommended concentrations to prevent any potential adverse reactions.

INCI


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.
