What is Shellac?

Shellac is made by the insect Laccifer lacca. Don't confuse shellac made by this insect with the varnish-like product found at hardware stores. Varnish-like shellac contains methanol (wood alcohol) and is very poisonous.

In dentistry, shellac from Laccifer lacca is used to make dentures and other dental products. In the pharmaceutical industry, shellac is used as a tablet coating and for other uses. In manufacturing, shellac is used as a finish for furniture, an ingredient in hair spray and in other cosmetics. Although shellac has been used for years in pharmacy, dentistry, and manufacturing, it has fallen into disfavor for some products because it ages over time.

Shellac does not have any medicinal uses.
