What is Isohexadecane?

Isohexadecane is a high-purity, branched-chain hydrocarbon. It is derived from petroleum sources and is a part of the group known as alkanes. Due to its process of purification, it is often used in cosmetics and personal care products.

This ingredient is used primarily as an emollient and texture enhancer. It provides a silky, non-oily feel to formulations, which is why it's popular in sunscreens, moisturizers, and other skin care products. Studies suggest it's generally non-irritating and safe for use on the skin, but individual reactions can vary.

When you see isohexadecane on a label, it's usually there to improve the product's texture and application. Consumers looking for non-greasy, light formulations might appreciate its inclusion.

Commonly found in: sunscreens, moisturizers, makeup removers, foundations, lipsticks
