Science
Mechanism of Action
Isohexadecene primarily functions as an emollient, effectively softening and soothing the skin by creating a protective barrier that helps lock in moisture without leaving a greasy sensation. Its solvent properties are crucial for dissolving other ingredients and ensuring uniform dispersion of pigments and active compounds within formulations. Furthermore, it acts as a texture enhancer, providing excellent slip and spreadability, and its volatile nature allows for a fast-absorbing, dry-touch finish, making it ideal for delivering active ingredients and improving the longevity of long-wear products.

Key findings
- 01 Concentrations from 2% to 25% are commonly utilized to improve cosmetic texture, slip, and spreadability, with lower levels enhancing slip and higher concentrations prevalent in anhydrous formulations like cleansing balms and foundation sticks.
- 02 At 2% to 20%, Isohexadecene effectively enhances film formation and water resistance, particularly beneficial in long-wear makeup and sunscreens, simultaneously imparting a light, silky feel in serums and gels.
