What Palmitic Acid does

Thickens creams, lotions and body butters
Gives bars and cleansers a firm body
Adds structure to mascara and sticks

Palmitic acid is one of the most common fatty acids in nature. It is found in palm oil, shea butter, cocoa butter and animal fats. Manufacturers usually get it from these oils and refine it into a purer form.

Formulators use it because it is solid at room temperature and gives a creamy, slightly waxy structure. It helps thicken lotions and creams, and it adds firmness to bars and sticks. In soap bars, it reacts with an alkali to form a soap, which is why it appears in many cleansers. In mascara, it helps build body. On skin, it feels smooth and cushiony rather than greasy.
