The blend produces a new ingredient that offers emollient, binding, and film-forming properties. Polyamide-8 is often used in sunscreens, lipsticks, lip glosses, and eyeshadows due to its water- and transfer-resistant properties which improve wear time. It is compatible with a wide range of oils, where it helps provide better structure. The molecular weight of this ingredient prohibits penetration into skin. Usage levels of polyamide-8 range from 1-10%, though lower amounts may be used depending on the intended results. It is considered safe as used in cosmetics.
