Science & Benefits

Ceteareth-20 is a fatty alcohol polyether. While an excellent emulsifier, it carries a logic warning: when combined with Cetearyl Alcohol, its comedogenic potential spikes. For acne-prone users, it is 'Average' because it can be slightly irritating to a compromised barrier. In 2026, it is considered a 'yellow flag'—safe in wash-off products, but potentially congesting in heavy, leave-on creams.
