Dewaxed bleached shellac is a hard, wax-free shellac that provides a bright shine. It is non-toxic and FDA-approved for use in food and pharmaceutical products. The bleaching process involves dissolving shellac in an alkaline solution, then precipitating and washing a bleached powder. Dewaxed bleached shellac has many industrial uses, including as a coating for fruits, vegetables, tablets, confections, and more. It performs functions like enhancing gloss, providing a moisture barrier, and extending shelf life.

1. Dewaxed Bleached Shellac
Dewaxed white shellac is used the same way as you would any
other grade of shellac. The major difference between this shellac
and the others is that it is a bit harder, shines a bit brighter, is
completely free from wax.
Bleached shellac is non-toxic, edible and used widely in different
industries including Food, food packaging and allied industries.
Bleached lac has super characteristics and qualities i.e. adhesive,
binding, hardening, gloss, odorless.
Fast drying, extending shelf life. And most clear, transparent or very light colored Alkali solutions can
be obtained from it. Bleached shellac is available in two grades: waxy and dewaxed bleached shellac.
Process of Bleached Shellac
The basic procedure in the bleached process consists in dissolving lac in aqueous sodium carbonate
solution at 90-100 degree celcius, stirring off the dissolved materials and treating the solution with
sodium hydrochloride solution and the start filtration after cooling down the temperature of solution.
The bleached lac is reclaimed from the filtered solution with sulphuric acid. The precipitated bleached
lac is then filtered and washed from water for removal of acid and dried.
The dewaxed bleached shellac powder is approved by FDA USA for application in food and
pharmaceutical products and conforms to specification according to usp-21 nf 18.
Packing: 25 kgs packed in 5 ply craft paper bags.
Storage: Must be stored below 10 degree celcius in cool and dark place.
