Aleuritic acid is a major ingredient in shellac,
constituting about 35% of it. Aleuritic acid is also known as red lac acid,
shellac acid Red lac resin is a polyester compound made by multi - hydroxyl
fatty acid and sesquiterpene acid, among which multi-hydroxyl fatty acid is lac
acid. Shellac acid is the main component of the composition of natural shellac,
and a part of lac resin, it is a white crystalline that takes 20% -30%,
molecular formula is C16H32O5, contains three free hydroxyl and one free
carbonxyl, and its also called 9,10,16 - trihydroxy palmiticacid. It is used as
a starting material in the perfume industry for the preparation of musk aroma.
Aleuritic acid has a wide range of applications, not only can be used as macro
cyclic musk fragrance compounds, prostaglandin, insect pheromones, cyclic
ureide, nutritional energy material, it also can be applied in UV resistance,
radiation resistance, heat-resistant aeronautic/aerospace materials and
equipment. Its traits are soluble in hot water, methanol, ethanol, and
isopropanol; insoluble in cold water, ether, petroleum ether, and carbon
disulfide. Aleuritic acid is pretty odorless and is physically detectable as a
fine white powder
