    Stearic acidoccurs in many animal and vegetable fats and oils,but it is more abundant in animal fat (up to 30%) than vegetable fat (typically <5%).The important exceptions are cocoa butter and shea butter where thestearic acidcontent (as a triglyceride) is 28–45%.[3]

    Stearic acidis prepared by treating these fats and oils with water at a high pressure and temperature (above 200 °C),leading to the hydrolysis of triglycerides.
