Science & Benefits

Oleth-3 is a polyethylene glycol ether of oleyl alcohol. It is one of the most aggressive comedogens in cosmetic chemistry (Rating 5). Its structure is highly 'bio-available' to the sebaceous follicle, where it promotes the formation of impactions. It should be strictly avoided by anyone with acne-prone skin, particularly in leave-on products like moisturizers or primers.
