Crotonic acid/vinyl C8-12 isoalkyl esters/VA/bis-vinyldimethicone 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 crotonic acid, vinyl C8-12 isoalkyl esters, vinyl acetate and bis-vinyldimethicone.
It appears as a colourless to yellowish liquid.
Safety
Dimethicone is considered a safe component and impurities, according to the most up-to-date data, are of no health concern.
What it is used for and where
Cosmetics
Film-forming agent. It produces a continuous ultra-thin film with an optimal balance of cohesion, adhesion and stickiness on the skin or hair to counteract or limit damage from external phenomena such as chemicals, UV rays and pollution.
Hair conditioning agent. A large number of ingredients with specific purposes can co-exist in a hair shampoo: cleansers, conditioners, thickeners, mattifying agents, sequestering agents, fragrances, preservatives, special additives. However, the indispensable ingredients are the cleansers and conditioners as they are necessary and sufficient for hair cleansing and manageability. The others act as commercial and non-essential auxiliaries such as: appearance, fragrance, colouring, etc. Hair conditioning agents have the task of increasing shine, manageability and volume, and reducing static electricity, especially after treatments such as colouring, ironing, waving, drying and brushing. They are, in practice, dispersing agents that may contain cationic surfactants, thickeners, emollients, polymers. The typology of hair conditioners includes: intensive conditioners, instant conditioners, thickening conditioners, drying conditioners.
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.
