Polyglyceryl-3/lauryl polydimethylsiloxyethyl dimethicone crosspolymer is a chemical compound, silicone elastomer with characteristics of high heat resistance and elasticity adaptable to both high and low temperatures, consisting of crosslinked dimethicone copolymers with a bifunctional agent. It is produced by hydroxylation by adding silicon hydride bonds with a catalyst, usually platinum. Crosslinked polymer containing polyglyceryl-3 and lauryl polydimethylsiloxyethyl dimethicone.
The name defines the structure of the molecule
- "Polyglyceryl-3". Indicates a polymer derived from glycerol, which is a tri-valent alcohol. The "3" suggests that there are three glycerol units in the polymer.
- "Lauryl". Indicates the presence of a lauryl side chain, which is an alkyl group with the formula C12H25.
- "Polydimethylsiloxyethyl". Refers to a polymer of siloxanes with methyl and ethyl groups attached.
- "Dimethicone". Is a type of silicone used for its lubricating and water-repellent properties.
- "Crosspolymer". Indicates that the polymer has a crosslinked structure, meaning the polymers are bonded together in a three-dimensional network.
Description of raw materials used in production
- Polyglyceryl-3 - A modified glycerol polymer.
- Lauryl Polydimethylsiloxyethyl Dimethicone - A silicone compound modified with a lauryl group.
- Crosslinking Agent - Used to create bonds between the polymer chains (e.g., tetraethoxysilane).
Step-by-step summary of its industrial chemical synthesis process.
- Preparation of Monomers - Polyglyceryl-3 and lauryl polydimethylsiloxyethyl dimethicone are prepared or purchased as raw materials.
- Mixing - The monomers are mixed together in an appropriate solvent to form a homogeneous mixture.
- Polymerization and Crosslinking - The crosslinking agent is added, and the mixture is heated to initiate the polymerization and crosslinking reaction.
- Purification - The polymer is purified to remove impurities and unreacted solvents.
- Drying - The purified polymer is dried to remove residual solvents.
What it is used for and where
Cosmetics
Viscosity Enhancing Agent - non acqueous. Since viscosity is important for increasing the chemical and physical stability of the product, Viscosity Enhancing Agent non acqueous is an important dosage factor in gels, suspensions, emulsions, solutions. Increasing viscosity makes formulations less sedimentary and more homogeneously thickened.
Commercial applications
Thickening Agent. This polymer is used to increase the viscosity of cosmetic products, such as creams and lotions.
Emulsifier. Helps to form stable emulsions by mixing water and oils in cosmetic formulations.
Skin Conditioning Agent. Used in skin care products to improve the appearance and feel of the skin.
Film-Forming Agent. Forms a thin film on the surface of the skin or hair, enhancing appearance and providing protection.
Rheology Modifier. Alters the viscosity of cosmetic products, allowing for better application and feel on the skin.
Safety.
Dimethicone is considered a safe component and impurities, according to the most up-to-date data, are of no health concern. The other chemical compounds present are of no concern.
