Description

Polyglyceryl-6 behenate is a type of polyglyceryl ester used in cosmetic formulations. It is derived from behenic acid and polyglycerin, and functions primarily as an emulsifier and stabilizer. This ingredient helps to blend oil and water-based components in cosmetic products, improving their texture and consistency.

Chemical Composition and Structure

Polyglyceryl-6 behenate is composed of:

Polyglycerin: A polymer of glycerin, which provides hydrophilic properties and helps stabilize emulsions.
Behenic Acid: A long-chain fatty acid derived from behen oil, which contributes to the emulsifying properties and texture of the formulation.

Physical Properties

Polyglyceryl-6 behenate exhibits the following properties:

Appearance: Typically a white to off-white solid or waxy substance.
Aroma: Generally has a neutral or mild odor.
Texture: Provides a smooth and creamy texture, enhancing the stability and application of cosmetic products.

Production Process

The production process for polyglyceryl-6 behenate involves:

Synthesis of Polyglycerin: Glycerin is polymerized to form polyglycerin through a chemical reaction involving heat and catalysts.
Preparation of Behenic Acid: Behenic acid is obtained from behen oil, which is extracted from the seeds of the Moringa oleifera plant.
Esterification Reaction: Polyglycerin and behenic acid are reacted together to form polyglyceryl-6 behenate. This reaction typically involves the use of catalysts and specific conditions to ensure proper ester formation.
Purification: The resulting compound is purified to remove any unreacted materials and to ensure the quality of the final product.
Formulation: The purified polyglyceryl-6 behenate is incorporated into cosmetic formulations where it acts as an emulsifier and stabilizer.
Quality Control: The final product undergoes quality control testing to ensure it meets safety and performance standards.

Applications

Medical: While not commonly used in medical applications, polyglyceryl-6 behenate may be included in dermatological formulations for its emulsifying and stabilizing properties.
Cosmetic: It is widely used in skincare products such as creams, lotions, and serums, where it helps to create stable emulsions and improves the texture and application of the products.
Other: Its use in non-cosmetic applications is limited, but it may be found in other personal care products that require effective emulsification.

Environmental and Safety Considerations

Polyglyceryl-6 behenate is generally considered safe for use in cosmetics when used according to recommended guidelines. It is derived from renewable sources, and its production involves processes that minimize environmental impact. Adherence to safety and quality control standards ensures the ingredient is safe for consumer use.

INCI


Emulsion stabiliser. Emulsions are thermodynamically unstable. Emulsion stabilisers improve the formation and stability of single and double emulsions. as well as their shelf-life. It should be noted that in the structure-function relationship, the molar mass of the ingredient used plays an important role.
