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 dimethicone..
The name describes the structure of the molecule:
- Dimethicone refers to dimethicone, a type of silicone used in cosmetics for its emollient and protective properties. Dimethicone is known for creating a barrier on the skin that retains moisture and provides softness and shine.
- crosspolymer indicates that the compound is a crosslinked polymer. Crosslinked polymers have a three-dimensional structure that can improve the stability, strength, and viscosity of the product.
Raw Materials and Their Functions
Silicon Hydride. Used as a reactant in the crosslinking reaction to introduce crosslinks into the dimethicone.
Platinum Catalyst. A catalyst used to facilitate the crosslinking reaction between dimethicone molecules and silicon hydride.
Industrial Chemical Synthesis of Dimethicone Crosspolymer
- Hydroxylation. The process begins with the addition of silicon hydride bonds to dimethicone in the presence of a platinum catalyst. This reaction introduces crosslinks into the molecular structure of dimethicone.
- Reaction Control. The hydroxylation reaction is carefully controlled to ensure the correct formation of crosslinks and to achieve the desired properties in the final product.
- Purification. After the reaction, the dimethicone crosspolymer is purified to remove impurities and by-products.
- Quality Control. The purified dimethicone crosspolymer undergoes quality checks to ensure it meets the required standards. After quality control, it is packaged for use in cosmetic products, where it utilizes its properties as a film-forming agent and to enhance the texture of products.
Form and Color
Dimethicone Crosspolymer is typically an elastic solid or a paste. This compound is usually colorless or very light in color.
What it is used for and where
Dimethicone Crosspolymer is widely used in cosmetic and skincare products, such as creams, lotions, foundations, and sun care products.
Cosmetics
Dispersing agent - Non surfactant. Ingredient that can change and stabilize the surface characteristics of the suspension, covering the surface. It also works as a hair fixative.
Emulsion stabilizer. Emulsions are thermodynamically unstable. Emulsion stabilisers improve the formation and stability of single and double emulsions. It should be noted that in the structure-function relationship, molar mass plays an important role.
Hair fixative. This ingredient has the ability to create, with its protective film, stiffness and hold in the hair, and also has the ability to form, with its hydrophilic and elastic properties, bonds between the hair fibres, to keep the hair in a particular shape for a certain time.
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.
