The natural foundation of shellac: A sustainable product built in an environmentally responsible environment.
Seedlac is the raw, unrefined resin excreted by the Kerria lacca insect. Naturally containing resin, wax, and other organic substances, Seedlac is the key starting material for refined Shellac and a wide range of lac-based derivatives. Owing to its versatile properties, it finds extensive use in industries such as food, pharmaceuticals, cosmetics, woodworking, and more. At India Shellac, we source and supply premium Seedlac in multiple grades to cater to specific application requirements.
