Shellac is an alcohol soluble natural resin of animal origin. The shellac is produced by female scallop lice, thousands of which live as parasites on certain shrubs in East India and Thailand. The secretion of these lice covers the branches in thick layers, which are harvested twice a year, to protect the brood.
In addition to dead lice, the dried secretion contains about 60 – 80% pure shellac and 4 – 6% wax. Shellac of different qualities is obtained by cleaning and bleaching.
Areas of application for shellac can be found e. g. in the pharmaceutical industry (dragee glazes), in insulating paints, wood polishes, finishes, chewing gum and inks.
