Lac is a natural resin produced by certain insects, primarily the lac insect found in tropical and subtropical regions. This resin is secreted by the insects as a protective coating for their eggs and is harvested for various uses, including the production of shellac, a popular wood finish and food glaze.
The harvesting process involves collecting the resin from tree branches where the lac insects reside. Once collected, the resin is processed to remove impurities and can be used in various applications, such as in cosmetics, pharmaceuticals, and as a dye. Lac has been utilized for centuries in different cultures around the world.
