Continuation of natural oils

safflower oil where no comedogenic effects have been found. Other examples of natural triglycerides are peanut oil, soy oil, olive oil, wheat germ oil and avocado oil.
A special triglyceride is castor oil, which is obtained from the seed of Ricinus communis. This oil is based on ricinoleic acid, an unsaturated C18 hydroxy fatty acid. Contrary to other triglycerides, it is easily soluble in alcohol. Castor oil is used in lipsticks and also in alcoholic preparations.

Jojoba oil

Unlike the oils described in the previous section, jojoba oil is not a triglyceride. It is a liquid, unsaturated wax from the esters of long carbon-chain fatty acids (C20 to C22) and long carbon-chain unsaturated alcohols (C20, C22). Its source is the jojoba plant, which grows in California and Mexico. Jojoba oil has a very fatty character and shows excellent cosmetic properties.
