Recognized as safe by the US FDA and labeled GRAS (Generally Recognized as Safe), shellac is widely used as a coating for various foods, including fruits, coffee beans, chewing gum, chocolates, and candies. In the pharmaceutical industry, it serves as a food-grade pharmaceutical glaze, an alcohol-based solution used to coat pills and other medications.
Shellac is a natural bioadhesive polymer, chemically similar to synthetic polymers, which makes it comparable to a natural form of plastic. Traditionally known as one of the best wood sealers, shellac is frequently used as a wood finish, particularly in the French Polish technique. In addition to its use as a wood coating, shellac and its by-products, such as shellac wax and lac dyes, are used in the cosmetics and garment industries.
