Chemical structure of ceteareth-n, where n is variable from 2 to 100 and m is 15 or 17. The INCI names ceteareth-n (where n is a number) refer to polyoxyethylene ethers of a mixture of high molecular mass saturated fatty alcohols, mainly cetyl alcohol (m = 15) and stearyl alcohol (m = 17).
Isoceteth-20 is a polyethylene glycol ether formed by the ethoxylation of iso-cetyl alcohol; with the general formula HO(C 2 H 4 O) n C 16 H 33 where n has an average value of 20. It is a nonionic surfactant used as an emulsifier in some personal care products. [1] However, as iso-cetyl alcohol is rare in nature isoceteth-20 does not see ...
Common examples include emulsifying wax, polysorbate 20, and ceteareth 20. [25] Sometimes the inner phase itself can act as an emulsifier, and the result is a nanoemulsion, where the inner state disperses into "nano-size" droplets within the outer phase.
Acne cosmetica is a type of contact acneiform eruption caused by or aggravated by cosmetics. [1] Signs and symptoms include a dense group of similar sized closed comedones and scattered small bumps, typically over the skin where the cosmetic has been applied. [1]
