Rice bran wax is edible and can serve as a substitute for carnauba wax in most applications due to its relatively high melting point.
It is used in paper coatings, textiles, explosives, fruit and vegetable coatings, confectionery, pharmaceuticals, candles, moulded novelties, electric insulation, textile and leather sizing, waterproofing, carbon paper, typewriter ribbons, printing inks, lubricants, crayons, adhesives, chewing gum and cosmetics.
[1] In cosmetics, rice bran wax is used as an emollient, and is the basis material for some exfoliation particles.
It has been observed that rice bran wax at concentrations as low as 1 wt% in triglycerides can crystallize to form stable gels.
