Description

Polyglyceryl-10 Dimer Dilinoleate/Stearate/Hydroxystearate is a chemical compound formed by the esterification of polyglycerin-10 with a mixture of dimerized linoleic acid, stearic acid, and hydroxystearic acid. This compound is valued for its emollient, emulsifying, and moisturizing properties, making it useful in various cosmetic and pharmaceutical applications.

CHEMICAL COMPOSITION AND STRUCTURE

Chemically, polyglyceryl-10 dimer dilinoleate/stearate/hydroxystearate consists of esters formed from the reaction of polyglycerin-10 with a mixture of dimerized linoleic acid, stearic acid, and hydroxystearic acid. this combination imparts unique moisturizing and emulsifying properties to the compound:

Polyglycerol Backbone: a polymer of glycerin that imparts hydrophilic (water-attracting) properties.
Dimerized Linoleic Acid: provides enhanced emollient properties and helps to improve the stability of the final product.
Stearic Acid and Hydroxystearic Acid: fatty acids that add hydrophobic (water-repelling) properties, enhancing the compound’s ability to blend oil and water phases.

PHYSICAL PROPERTIES

Appearance: generally a clear to pale yellow liquid or semi-solid.
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 dimerized linoleic acid, stearic acid, and hydroxystearic 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 moisturizing properties, helping to improve skin health and repair the skin barrier.
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 skin texture in products like moisturizers, serums, and creams.
Hair Care: provides conditioning effects and improves the spreadability 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 emulsifier and stabilizer in various industrial formulations, including lubricants and surface treatment agents.

ENVIRONMENTAL AND SAFETY CONSIDERATIONS

Biodegradability: polyglyceryl-10 dimer dilinoleate/stearate/hydroxystearate 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


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.

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.
