Our take
Is Isohexadecane a Good Ingredient?
Rated Good as a highly stable, inert emollient with an extensive use history, offering elegant slip and helping dilute heavier oils, with very low irritation and a low likelihood of clogging pores. Its consistency and volatility profile deliver lightweight textures across product types, solid functional strengths that still keep it in the Good range rather than Great.
