Ceteth-20

Other names: Polyoxyethylene ( 20 ) Cetyl Ether

Harm score: 4 (Slightly harmful chemistry)

Ceteth-20, also known as Polyoxyethylene (20) Cetyl ether, is a largely used chemical compound in the cosmetic industry. It is a non-ionic tenside derived from cetyl alcohol and ethylene oxide. Ceteth-20 is a colorless liquid with a faint odor, and it evaporates on contact with oxygen and under moisture. The chemical compound is capable of reducing the surface tension between two substances, allowing them to mix with each other. As a result, this substance is commonly used as an emulsifier in cosmetic products.

Ceteth-20 is widely used in body care products such as creams, lotions, shampoos, conditioners, cleansing gels or body washes. The fact that it lowers the surface tension between water and oil allows for the formation of a stable cream or lotion base that is more user-friendly. It is also often included in skin and hair care products as it aids the absorption of active ingredients into the skin or hair. It is also included in some types of make-up. Ceteth-20 is a frequently used ingredient in the cosmetic industry, and despite its synthetic origin, it can be considered a safe and effective ingredient. The level of its use is regulated by the European Union, which sets the maximum concentration allowed in cosmetic products.
