Isododecane is a synthetic aliphatic hydrocarbon with a branched structure. It is a safe, non-irritating, and non-comedogenic cosmetic-grade solvent and emollient with low viscosity, good volatility, spreadability, and drying time. It is a relatively inert, colorless, odorless ingredient suitable for almost all types of skin, hair, sun, and lip care preparations.

Thanks to good solubilizing properties, Isododecane is suitable for cleansing applications which eliminate oil, dirt, and impurities from the skin's surface and effectively remove decorative cosmetics. It is compatible and completely soluble with silicones, hydrocarbons, isoparaffin, and mineral spirits.

Isododecane is highly volatile and is usually used in non-residual products. It has a low density and low viscosity. It can be used as a replacement for oils in emulsions that leave a light non-greasy feeling.

In combination with Isohexadecane or Isoeicosane (which have similar molecular structures), it enables a wide range of skin feel, playtime, and plasticity depending on concentrations and desired results. Thanks to high stability, Isododecane is used as an emollient and solid (UV-filter) carrying agent in many sun care applications.

It is a good ingredient for decorative cosmetics including, mascaras, lipsticks, and eyeliners incorporated as a soft emollient, pigment-carrying agent, or plasticizer. Isododecane is miscible with silicones, other hydrocarbons, mineral oils, and alcohols. In addition, it can be used as a co-solubilizer or co-emulsifier for many non-hydrocarbon materials.

Isododecane is used in mascara, eyeliner, creams, lotions, hair care, conditioners, setting lotions, and hairsprays. It is dermatologically safe and typically used at concentrations of 2-15%.

Isododecane is a clear, color- and odorless, volatile liquid, which makes it perfect for use in color cosmetics like mascara, eyeliner, lip products, or any product where improved wear properties and no residues are wanted. Ideal for make-up removers - no oily residue. It is also used as a lipophilic ingredient for deodorant sprays and hair care products.

Isododecane complies with the regulations in the European Union, the United States of America, and Japan.
