Octadecanoic acid, also known as stearic acid, is a saturated fatty acid with an 18-carbon chain and the CAS number 7691-02-3. It is found in the form of white, waxy, crystalline powder. Stearic acid is insoluble in water, but soluble in most organic solvents.
Stearic acid is a common component of many personal care products, such as lotions and creams, as well as industrial products, such as lubricants, candles, soaps, and cosmetics. It is used to add texture and hardness to products, to act as a lubricant and to prevent ingredients from separating.
In the food industry, stearic acid is used as an emulsifier and stabilizer in candy and chocolate products, as well as in margarine and shortening. It is also used as a release agent in baking, as a thickener in soups and sauces, and as a texturizer in many foods.
In the pharmaceutical industry, stearic acid is used as a binder and disintegrant in tablet formulations, as well as a lubricant in the manufacturing process. It is also used as a vitamin supplement, as it can help the body absorb vitamins A, D, and E.
In the rubber industry, stearic acid is used as an activator and accelerator in the manufacturing process. It is also used as an antistatic agent for rubber products, to reduce the surface friction of rubber, and to increase its flexibility.
More recently, stearic acid has been used in the production of biodiesel, as a fuel additive, and in various other industrial applications.
Overall, the versatility of this substance makes it a valuable component in many industries. Stearic acid is an important raw material in many products, and its CAS number of 7691-02-3 makes it easy to identify and track.
