Science & Benefits

Cetearyl Isononanoate is a dry-touch emollient ester that provides a sophisticated, silky skin feel without the heavy, occlusive nature of traditional oils. In modern formulation, it is used to reduce the 'greasiness' of sunscreens and heavy creams. Its molecular structure allows it to spread rapidly across the skin surface, forming a thin, breathable layer that prevents water loss without trapping heat or bacteria. With a comedogenic rating of 1, it is considered very safe for acne-prone skin. It is an 'intellectual' alternative to pore-clogging esters like Isopropyl Myristate, providing the same luxury feel with a significantly lower risk of inducing acne cosmetica.
