Description

Polyglyceryl-3 Dicaprate is a specialized cosmetic ingredient primarily used as an emulsifier and skin conditioner in an array of skincare and makeup products. It results from the esterification of polyglycerin-3 with capric acid, producing an ester known as 1,2,3-Propanetriol, homopolymer, decanoates in a 1:2 molar ratio with an average of 3 moles of glycerol. This ingredient is favored for its ability to enhance the texture and stability of cosmetic formulations, as well as for its moisturizing properties.

Chemical Composition and Structure

This ester links the hydrating properties of polyglycerin-3, a polymer of glycerin known for its moisturizing benefits, with the fatty acid capric acid, which is known for its light skin feel and quick absorption. This combination results in a molecule that effectively stabilizes oil-in-water emulsions and improves the spreadability and absorption of cosmetic products.

Physical Properties

Polyglyceryl-3 Dicaprate typically appears as a clear to pale yellow viscous liquid. It is characterized by its solubility in oils and moderate solubility in water, making it highly suitable for use in both hydrophilic and lipophilic phases of emulsions, where it aids in achieving a smooth and non-greasy feel.

Production Process

Synthesis: The synthesis of Polyglyceryl-3 Dicaprate involves the controlled esterification of polyglycerin-3 with capric acid. This process is typically managed under specific conditions to ensure efficient ester bond formation and high product purity.
Purification: After synthesis, the compound is subjected to various purification steps to remove any unreacted materials and impurities, achieving a high level of purity that is required for cosmetic use.
Quality Control: Rigorous testing is performed on the final product to ensure its stability, efficacy, and compatibility with other cosmetic ingredients. These tests typically include viscosity measurements, stability testing under different conditions, and performance evaluations in emulsion systems.

Applications

Cosmetic Products: Widely used in creams, lotions, and serums where it acts as an effective emulsifier, helping to blend and stabilize oil and water components, thereby enhancing the consistency and sensory properties of the product.
Skin Care: Particularly useful in light moisturizing formulations intended for oily or combination skin, as it helps to impart moisture without leaving a heavy residue.
Makeup: Employed in makeup products to improve application properties and enhance the longevity of wear, providing a smooth and even coverage.

Environmental and Safety Considerations

Polyglyceryl-3 Dicaprate 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. Being derived from natural fatty acids, it is also regarded as environmentally friendly. Proper usage within recommended concentrations is crucial to ensure safety and optimal performance.

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.
