Shellac is a natural resin refined from Lac. It is used as a coating agent, glazing agent, surface finishing agent. It is European Union Approved Food Additive: E904 - Glazing Agent.

DEFINITION
Shellac is obtained by the purification of lac, the resinuous secretion of the insect Kerria lacca (Kerr) Lindinger (Laccifer lacca Kerr) (Fam. Coccideae). Shellac is a polyester resin consisting of inter- and intra-esters of polyhydroxyl carboxylic acids formed from certain hydroxyl acids and sesquiterpenic acids, and also contains variable amounts of wax. There are four types of Shellac depending on the nature of the treatment of crude secretion (seedlac).
1. Orange Shellac is produced by a process of filtration in the molten state and/or by a process of solvent extraction. Orange Shellac retains most of its wax.
2. Refined (Dewaxed) Orange Shellac is produced by filtration of the wax in a solvent process. It may also be decolorized by activated carbon.
3. Regular Bleached (white) Shellac is prepared by dissolving the lac in an alkaline solution and bleaching the solution with sodium hypochlorite. It is precipitated by dilute acid and dried.
4. Refined Bleached Shellac is prepared by dissolving the lac in an alkaline solution and bleaching the solution with sodium hypochlorite. During the process, wax is removed by filtration. It is precipitated by dilute acid and dried.

Table 1 Shellac conforms to the specifications as under:
Orange Shellac: Acid Value (on dried basis) 68–76; Loss on Drying (%) NMT 2.0; Wax (%) NMT 5.5
Refined Orange Shellac: Acid Value (on dried basis) 68–79; Loss on Drying (%) NMT 2.0; Wax (%) NMT 0.2
Regular Bleached Shellac: Acid Value (on dried basis) 73–89; Loss on Drying (%) NMT 6.0; Wax (%) NMT 5.5

Labeling: Label it to indicate the type of Shellac.

DEFINITION
Purified material obtained from the resinous secretion of the female insect Kerria lacca (Kerr) Lindinger (Laccifer lacca Kerr). There are 4 types of shellac depending on the nature of the treatment of crude secretion (seedlac): wax-containing shellac, bleached shellac, dewaxed shellac and bleached, dewaxed shellac.
Wax-containing shellac is obtained from seedlac: it is purified by filtration of the molten substance and/or by hot extraction using a suitable solvent.
Bleached shellac is obtained from seedlac by treatment with sodium hypochlorite after dissolution in a suitable alkaline solution, precipitation by dilute acid and drying.
Dewaxed shellac is obtained from wax-containing shellac or seedlac by treatment with a suitable solvent and removal of the insoluble wax by filtering.
Bleached, dewaxed shellac is obtained from wax-containing shellac or seedlac by treatment with sodium hypochlorite after dissolution in a suitable alkaline solution; the insoluble wax is removed by filtration. It is precipitated by dilute acid and dried.

CHARACTERS
Appearance: Brownish-orange or yellow, shining, translucent, hard or brittle, more or less thin flakes (wax-containing shellac and dewaxed shellac), or a creamy white or brownish-yellow powder (bleached shellac and bleached, dewaxed shellac).
Solubility: Practically insoluble in water, gives a more or less opalescent solution (wax containing shellac and bleached shellac) or a clear solution (dewaxed shellac and bleached, dewaxed shellac) in anhydrous ethanol. When warmed it is sparingly soluble or soluble in alkaline solutions.

IDENTIFICATION
A. Thin-layer chromatography.
B. Examine the chromatograms obtained in the test for colophony.
Results For wax-containing shellac, in the chromatogram obtained with the test solution, a more or less strong bluish-grey zone is visible, just above the zone due to thymolphthalein in the chromatogram obtained with the reference solution; for dewaxed shellac, no such zone is visible just above the zone due to thymolphthalein in the chromatogram obtained with the reference solution.

TESTS
Acid value: 65 to 95 (dried substance).
Colophony: Thin-layer chromatography.
Arsenic: Maximum 3 ppm.
Loss on drying: Maximum 2.0 per cent for unbleached shellac and maximum 6.0 per cent for bleached shellac, determined on 1.000 g of the powdered substance (500) by drying in an oven at 40-45C for 24 h.

STORAGE
Protected from light. Store bleached shellac and bleached, dewaxed shellac at a temperature not exceeding 15C.

DESCRIPTION
Shellac, Bleached, occurs as an off white to tan, amorphous, granular resin. Shellac is obtained from lac, the resinous secretion of the insect Laccifer (Tachardia) lacca Kerr (Fam. Coccidae). Shellac, Bleached, is obtained by dissolving the lac in aqueous sodium carbonate, followed by bleaching with sodium hypochlorite, precipitation of the bleached lac with a dilute sulfuric acid solution, and drying. It is freely (though very slowly) soluble in alcohol, insoluble in water, and slightly soluble in acetone and in ether. Shellac, Bleached, is usually dissolved in a suitable solvent for application to food products.
Function: Coating agent; surface-finishing agent; glaze.

REQUIREMENTS
Identification: Create a solution of 1 g of ammonium molybdate in 3 mL of sulfuric acid. Add a few drops of this solution to 50 mg of sample. A green color appears and changes to lilac when the solution is neutralized with 6 N ammonium hydroxide.
Acid Value: Between 73 and 89.
Lead: Not more than 2 mg/kg.
Loss on Drying: Not more than 6.0%.
Rosin: Passes test.
Wax: Not more than 5.5%.
