Description

Polyglyceryl-10/Sebacic Acid/Shea Butter Crosspolymer is a chemical compound, specifically a crosslinked polymer obtained by the reaction of polyglycerin-10, sebacic acid, and Butyrospermum parkii (shea) butter. This compound is valued for its emollient, film-forming, and stabilizing properties, making it useful in various cosmetic and personal care applications.

CHEMICAL COMPOSITION AND STRUCTURE

Chemically, polyglyceryl-10/sebacic acid/shea butter crosspolymer is formed through a crosslinking reaction between polyglycerin-10, sebacic acid, and shea butter. this structure provides a network that enhances the stability, texture, and moisturizing properties of formulations:

Polyglycerol Backbone: a polymer of glycerin that imparts hydrophilic (water-attracting) properties.
Sebacic Acid: a dicarboxylic acid that acts as a crosslinker, contributing to the polymer network and enhancing the compound's structural integrity.
Shea Butter: a natural emollient that adds hydrophobic (water-repelling) properties, contributing to the moisturizing and protective qualities of the polymer.

PHYSICAL PROPERTIES

Appearance: generally a creamy or solid material with a smooth texture.
Odor: mild, characteristic of shea butter.
Solubility: insoluble in water, but dispersible in oils and some organic solvents.
Density: varies depending on the specific formulation and crosslinking density.
Viscosity: can range from moderate to high, contributing to the thickening and film-forming properties in formulations.
PRODUCTION PROCESS

Preparation of Polyglyceryl-10: glycerin is polymerized to form polyglyceryl-10.
Crosslinking Reaction: polyglyceryl-10 is reacted with sebacic acid and butyrospermum parkii (shea) butter under controlled temperature and pressure conditions to form the crosslinked polymer.
Filtration and Purification: the resulting polymer is filtered and purified to remove impurities and ensure 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 film-forming and protective properties, helping to improve skin health and create a barrier against environmental stressors.
Cosmetics: commonly found in creams, lotions, emulsions, and hair care products as a thickening agent, film former, and stabilizer. enhances the texture, spreadability, and stability of cosmetic products.
Skin Care: improves hydration and provides a protective barrier in products like moisturizers, serums, and creams.
Hair Care: adds conditioning effects and improves the consistency of hair care formulations.
Makeup: used in foundations, primers, and other products for its film-forming and texturizing effects.
Industrial: utilized as a biodegradable stabilizer and film-forming agent in various industrial formulations, including surface treatments and coatings.

ENVIRONMENTAL AND SAFETY CONSIDERATIONS

Biodegradability: polyglyceryl-10/sebacic acid/shea butter crosspolymer 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


Humectant. Hygroscopic compound used to minimise water loss in the skin and to prevent it from drying out by facilitating faster and greater absorption of water into the stratum corneum of the epidermis. The epidermis is the most superficial of the three layers that make up human skin (epidermis, dermis and hypodermis) and is the layer that maintains hydration in all three layers. In turn, the epidermis is composed of five layers: horny, the most superficial, granular, spinous, shiny, and basal. Humectants have the ability to retain the water they attract from the air in the stratum corneum and have the function of moisturising the skin. They are best used before emollients, which are oil-based.

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.
