ISOSTEARICACID - Introduction
Isostearic acid (Isostearic Acid) is a fatty acid with the chemical formula C18H36O2. It is a colorless or pale yellow liquid with a high melting point and viscosity. It is obtained by hydroisomerization of stearic acid and contains mainly 2 stereoisomers, namely S and R isomers.
Isostearic acid has many applications. It can be used as a lubricant and stabilizer, especially in personal care products such as skin creams, lipstick and shampoo. Due to its viscosity and stability, isostearic acid is also used as a grease and can be used in products such as candles, inks and coatings. In addition, it can also be used in the manufacture of emulsifiers, drugs and plastics.
A common method for preparing isostearic acid is to react stearic acid with hydrogen at high temperature and pressure, using a suitable catalyst, such as palladium or nickel catalyst. This reaction results in hydrogenation of multiple double bonds of stearic acid to produce isostearic acid.
Regarding the safety of isostearic acid, it is considered to be a relatively safe substance. According to related research, isostearic acid is less permeable to human skin and can be excreted after being metabolized in the body. However, individuals may be allergic to isostearic acid, so use should be aware of possible allergic reactions. Use should follow the correct operating procedures, and avoid excessive contact and inhalation. In case of contact with skin or eyes, rinse immediately with water and seek medical help.
