Cosmetics are widely used in people’s lives. As a raw material for cosmetics, fatty acids play an important role. They are mainly used as oily raw materials for creams such as creams and cold creams. They can also be used as emulsifiers for cream products. In addition, they can also be used as fat enrichers, softeners, Solvents for skin cleansing, gloss agents for pastes, etc.
There are many kinds of fatty acids used as cosmetic raw materials, such as lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, Grease etc. The following supply of fatty acids briefly introduces the four types of fatty acids commonly used in cosmetic raw materials:
Lauric acid (lauric acid):White crystalline waxy solid, one of the main ingredients of soap. It is obtained from natural vegetable oils through saponification, decomposition under high temperature and pressure, or separation from synthetic fatty acids. The raw materials used for synthetic perfumes, shampoos and ointments in cosmetics are obtained. As emulsifiers and dispersants in the manufacture of cosmetics, it has good foaming properties and stable foam, so it is also used in products such as facial cleansers and shaving creams.
Myristic acid (myristic acid): White to yellowish white hard solid or powder, from coconut oil, palm oil Mixed fatty acids or methyl esters of mixed fatty acids obtained from kernel oil can be obtained by vacuum fractionation to obtain tetradecanoic acid. Like lauric acid, it is mainly used as a raw material for facial cleansers and shaving creams, and as a surfactant in soaps, soaps, detergents, and cosmetics.
Palmitic acid (hexadecanoic acid): White solid, mixed fatty acids or fatty acid methyl esters obtained from coconut oil and palm oil Obtained by vacuum fractionation. It is a raw material for creams, lotions, surfactants and oils.
Stearic acid (octadecanoic acid): It is a white flake, bead or block solid at room temperature. Stearic acid is a fatty acid widely found in nature. Almost all oils contain stearic acid in varying amounts. The content is higher in animal fats. For example, the content in butter can reach 24%, and in vegetable oils it is less. , tea oil is 0.8%, palm oil is 6%, but the content of cocoa butter is as high as 34%. Stearic acid is an indispensable raw material for dairy cosmetics and is commonly found in creams and lotions. It is mainly used for emulsification in skin care products such as snow cream and cold cream, thereby turning it into a stable and white paste. Stearic acid is also the main raw material for manufacturing almond honey and milk.
