Description

Polyglyceryl-8 C12-20 Acid Ester is an ester formed by the reaction of polyglyceryl-8 with a synthetic mixture of saturated acids containing 12 to 20 carbon atoms in the alkyl chain. these esters are valued for their emollient and emulsifying properties, making them useful in various cosmetic and pharmaceutical applications.

CHEMICAL COMPOSITION AND STRUCTURE

Chemically, polyglyceryl-8 C12-20 acid ester consists of a polyglycerol backbone with eight glycerol units esterified with a synthetic mixture of saturated acids containing 12 to 20 carbon atoms. this structure provides the compound with unique moisturizing and emulsifying properties.

PHYSICAL PROPERTIES

Appearance: generally a clear to pale yellow liquid.
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.

PRODUCTION PROCESS

Preparation of Polyglyceryl-8: glycerol is polymerized to form polyglyceryl-8.
Esterification: polyglyceryl-8 is reacted with a synthetic mixture of saturated acids containing 12 to 20 carbon atoms 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 moisturizing properties, helping to improve skin health.
Cosmetics: commonly found in creams, lotions, emulsions, and hair care products as an emollient and emulsifier. enhances texture, spreadability, and moisturizing effects of cosmetic products.
Others: used as a non-toxic, biodegradable emulsifier and stabilizer in various industrial formulations.

ENVIRONMENTAL AND SAFETY CONSIDERATIONS

Biodegradability: polyglyceryl-8 C12-20 acid ester is biodegradable, making it environmentally friendly.
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.
