Shellac is a natural resin refined from Lac, the secretion of the tiny red Lac insect, Kerria lacca, which is parasitic on certain host trees in India.

Wax-Containing Bleached Shellac is refined using the Bleaching Process, which involves dissolving Seedlac in an aqueous alkaline solution, such as sodium carbonate. The solution is then filtered to remove any insoluble material before being bleached with sodium hypochlorite to remove the colour. The Shellac is then precipitated from the solution by adding dilute sulphuric acid, before being filtered, washed with water and dried.


SWANLAC® Wax-Containing Bleached Shellac is sold in the form of an off-white powder and typically contains around 5% wax. It is soluble in alcohol and aqueous alkaline solutions.

SWANLAC® Wax-Containing Bleached Shellac is food grade and complies with EU Regulation 231/2012 and its specification for E904 Shellac as a food additive.


SWANLAC® Wax-Containing Bleached Shellac has a milky, honey-coloured appearance when prepared in an alcohol or aqueous alkaline solution, but dries to a clear film when applied as a surface coating.
