Description

Glyceryl/Polyglyceryl-6 Isostearate/Behenate Esters are a mixture of esters formed by the reaction of glycerin and polyglycerin-6 with isostearic acid and behenic acid. these esters are known for their emollient, stabilizing, and moisturizing properties, making them valuable in various cosmetic and pharmaceutical applications.

CHEMICAL COMPOSITION AND STRUCTURE

chemically, glyceryl/polyglyceryl-6 isostearate/behenate esters consist of 1,2,3-propanetriol, homopolymer (6 mol glycerol average), esterified with 1,2,3-propanetriol, isoocatdecanoic acid, and docosanoic acid. this complex structure provides unique solubility and stability properties.

PHYSICAL PROPERTIES

Appearance: generally a clear to pale yellow liquid.
Odor: characteristic mild odor.
Solubility: soluble in oils and various organic solvents.
Density: varies based on specific formulation and concentration of the esters.

PRODUCTION PROCESS

Preparation of Glycerin and Polyglycerin-6: glycerin is polymerized to form polyglyceryl-6.
Esterification: glycerin and polyglyceryl-6 are reacted with isostearic acid and behenic acid under controlled temperature and pressure 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, aiding in skin health improvement.
Cosmetics: commonly found in creams, lotions, emulsions, and hair care products as an emollient and stabilizer. enhances texture, spreadability, and stability of cosmetic products.
Others: used as a stabilizer and solubilizer in various industrial formulations.

ENVIRONMENTAL AND SAFETY CONSIDERATIONS

Biodegradability: glyceryl/polyglyceryl-6 isostearate/behenate esters are biodegradable, making them environmentally friendly.
Toxicity: generally considered non-toxic and safe for use in personal care and pharmaceutical products. however, it is essential to ensure 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


Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
