Cetearyl Alcohol is not a hormone, it is a fatty alcohol commonly used in the production of cosmetics. Cetearyl alcohol, also known as palmitol, is generally extracted from coconut and palm trees, and is a type of fatty alcohol, which has a white solid, granular, or waxy lumpy appearance, etc., and has an aroma. Thus it is not a type of hormone. Cetearyl Alcohol is mainly used in the production of cosmetics as an osmotic agent to increase the ability of cosmetics to penetrate into the skin, and it also serves as an emulsifier to increase the adhesion and spreading properties of cosmetics on the skin surface, making them easier to rub on. In addition, cetyl stearyl alcohol has a certain degree of resistance to oil, which makes waxes and raw materials less sticky, making it easier to store and so on. However, if cosmetics contain too much cetearyl alcohol, it can easily clog pores and cause inflammation of hair follicles. In addition, people with skin allergies should use cosmetics containing this ingredient with caution.
