Description

Polyglyceryl-10 Behenate/Eicosadioate is a chemical compound formed by the esterification of polyglycerin-10 with behenic acid and eicosadioic acid. This compound is valued for its emollient, emulsifying, and thickening properties, making it useful in various cosmetic and pharmaceutical applications.

CHEMICAL COMPOSITION AND STRUCTURE

Chemically, polyglyceryl-10 behenate/eicosadioate consists of a polyglycerol backbone with ten glycerin units esterified with a mixture of behenic acid and eicosadioic acid. this structure imparts unique thickening and emulsifying properties to the compound:

Polyglycerol Backbone: a polymer of glycerin that imparts hydrophilic (water-attracting) properties.
Behenic and Eicosadioic Acids: fatty acids that provide hydrophobic (water-repelling) properties, enhancing the compound’s ability to blend oil and water phases and contribute to thickening.

PHYSICAL PROPERTIES

Appearance: generally a solid or semi-solid with a smooth texture.
Odor: characteristic mild odor.
Solubility: insoluble in water, but dispersible in oils and some organic solvents.
Density: varies based on specific formulation and concentration of the esters.
Viscosity: moderate to high, depending on concentration, contributing to its thickening properties in formulations.

PRODUCTION PROCESS

Preparation of Polyglyceryl-10: glycerin is polymerized to form polyglyceryl-10.
Esterification: polyglyceryl-10 is reacted with behenic acid and eicosadioic acid under controlled temperature and pressure conditions to form the esters.
Filtration and Purification: the resulting esters are filtered and purified to remove impurities and obtain a high-quality product.
Packaging and Storage: the final product is packaged and stored in a cool, dry place to maintain its properties.

APPLICATIONS

Medical: used in topical formulations for its emollient and thickening properties, helping to improve skin health and provide a barrier function.
Cosmetics: commonly found in creams, lotions, emulsions, and hair care products as an emollient, emulsifier, and thickening agent. enhances the texture, spreadability, and stability of cosmetic products.
Skin Care: improves hydration and texture in products like moisturizers, serums, and creams.
Hair Care: provides conditioning effects and improves the consistency of hair care formulations.
Makeup: used in foundations, lipsticks, and other color cosmetics for improved application and feel.
Industrial: utilized as a non-toxic, biodegradable thickener and stabilizer in various industrial formulations, including lubricants and surface treatment agents.

ENVIRONMENTAL AND SAFETY CONSIDERATIONS

Biodegradability: polyglyceryl-10 behenate/eicosadioate is biodegradable, making it environmentally friendly and suitable for eco-conscious formulations.
Toxicity: generally considered non-toxic and safe for use in personal care and pharmaceutical products. however, it is essential to ensure that the product is free from contaminants and complies with regulatory standards.
Allergenicity: as with all chemical and natural compounds, individual reactions of intolerance or allergy cannot be excluded.

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.

Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
