Abstract
The present application provides high solids film coating compositions comprising a water-soluble cellulose ether, hydroxy propyl cellulose (HPC), a poly (N-vinyl pyrrolidone-co-vinyl acetate) copolymer, a film-forming agent based on D-glucose, plasticizer, medium chain triglycerides (MCT) and an anti-tack agent. The invention further provides a process for preparing the above described film coating compositions and method of coating solid substrate with such coating compositions.

- (iii) from 0.1 wt. % to 20 wt. % of polydextrose, a film forming agent;
- (iv) from 0.0 wt. % to 15 wt. % of polyethylene glycol, a plasticizer;
- and
- (v) from 1 wt. % to 10 wt. % of medium chain triglycerides (MCT).
A non-colorant film coating composition having total solids content of from about 20 wt. % to about 32 wt. %, the composition comprising:
- (i) from 0.1 wt. % to 20 wt. % of hydroxypropyl cellulose (HPC), a water soluble cellulose ether;
- (ii) from 0.1 wt. % to 40 wt. % of N-vinyl-2-pyrrolidone-co-vinyl acetate (PVP/VA) copolymer;
- (iii) from 0.1 wt. % to 20 wt. % of polydextrose, a film forming agent;
- (iv) from 0.0 wt. % to 15 wt. % of polyethylene glycol, a plasticizer;
- and
- (v) from 1 wt. % to 10 wt. % of medium chain triglycerides (MCT).
