WHAT IS ISOSTEARIC ACID USED FOR?
Isostearic Acid has multiple benefits to offer to the world of cosmetics.
Isostearic acid acts as a skin-conditioning agent, providing long-lasting moisture and helping to smooth the skin.
In emulsions like creams and lotions, Isostearic acid enhances texture and improves product stability by preventing the separation of oil and water.

ORIGIN OF ISOSTEARIC ACID:
Isostearic acid is made through the hydrogenation and isomerization of stearic acid, which is derived from natural sources such as vegetable oils (e.g., palm oil or soybean oil) or animal fats.
In the production process, stearic acid undergoes hydrogenation, where unsaturated bonds are converted to saturated ones.
Then, the stearic acid is isomerized, a process that rearranges the molecular structure to create a branched-chain fatty acid, resulting in isostearic acid.
