Description
A vegetable wax obtained from the leaves of the palm tree, Cocos coronapa, found in northeastern Brazil. Ouricury wax is very similar to carnauba, except that it has a greenish brown color that is difficult to bleach. Ouricury wax contains about 6% triterpenes. It is used as an inexpensive substitute for carnauba and is blended with carnauba to increase gloss.
