The natural moisturizing factor (NMF) exists in the stratum corneum of human epidermis to keep the skin moist. Cosmetics (especially emulsion cosmetics) are products specially used to adjust the skin. Its function should be the same as that of the sebum film, so it is often developed with the sebum film as the standard, so there is also a substance (humectant) that simulates the natural moisturizing factor of the skin. .

(Emulsifier) ​​A base cosmetic is composed of oil and water, and a substance that functions to mix oil in water or water in oil without separating them is a surfactant. The types of surfactants are nonionic active agents, anionic active agents, cationic active agents and amphoteric active agents. The addition of surfactants to cosmetics can achieve various functions such as washing, wetting, emulsifying, dispersing, solubilizing, and foaming.

Acids, alkalis, and salts are often added to cosmetics to adjust pH.
