Abstract: This invention relates to the field of aqueous and non-aqueous film coating of substrates like pharmaceutical tablets, nutritional supplements, food, confectionery items, agricultural seeds, and the like, and is specifically concerned with coating substrates with a coating based on low molecular weight hydroxypropyl methyl cellulose having low viscosity. The invention provides a composition where it provides a relatively faster rate of coating than those known in the prior art. The invention also relates to method of preparing such rapid film coating composition.
