Abstract:
The invention provides a novel immediate release, non-tacky film coating composition of PVA that is completely dispersed at ambient temperature and the process for the same.
Abstract:
The present invention is directed towards a dry mix composition that can be used to produce multi coloured tablets. The dry mix composition can be used to achieve a multi colour effect for uncoated and coated tablets. Coated tablets include any and all coatings applied over tablets like film coating, enteric coating, polymeric coats and other similar coatings. The dry mix composition comprises of commonly used excipients incorporating a fixing agent and a suitable pigment colour. A process to manufacture multi coloured tablets using the inventive dry mix composition is also described. The invention can be applied to pharmaceutical, food products, confectionery, agricultural seeds, nutritional feeds etc. Furthermore, the application describes the formulation variances by which the invented technology can easily be implemented on commercial levels.

A liquid coating solution or dispersion for forming a moisture barrier film coating for pharmaceutical tablets and the like comprises polyvinyl alcohol, self emulsifying glyceryl monostearate, water, and optionally a flow aid, a colorant, a plasticizer, a flavoring agent and nor a sweetening agent. A method of coating pharmaceutical tablets and the like with a moisture barrier film coating comprises forming a liquid coating solution or dispersion for forming a moisture barrier film coating for pharmaceutical tablets and the like comprising polyvinyl alcohol, self emulsifying glyceryl monostearate, water, and optionally a flow aid, a colorant, a plasticizer, a flavoring agent and/or a sweetening agent, applying the coating solution or dispersion onto the tablets to form a film coating on the tablets, and drying the film coating on the tablets.
Abstract:
A coating composition comprising sodium alginate and plasticizer, optionally detackifying agents, opacifÊers and colorants. The coating composition of the present invention may be applied to a pharmaceutical and veterinary tablet, caplets, pellets, granules, neutraceuticals, food, confectionery, seeds, animal feed, fertilizers and pesticide tablets and provides an elegant, glossy, prompt release coating which does not retard the release of active ingredients from the coated substrate.
Abstract:
A dry film coating composition for use in coating pharmaceutical tablets, nutritional supplements, food, confectionery forms, agricultural seeds, and the like, comprises polyvinyl alcohol, self emulsifying glyceryl monostearate, and preferably a plasticizer such as polyethylene glycol, glycerin or triethyl citrate, and a pigment/opacifier. A method of coating substrates such as pharmaceutical tablets, nutritional supplements, food, confectionery forms, agricultural seeds, and the like, with a film coating, comprises the steps of mixing polyvinyl alcohol, self emulsifying glyceryl monostearate, and preferably a plasticizer such as polyethylene glycol, glycerin or triethyl citrate, and a pigment/opacifier into hot water to form an aqueous coating dispersion, applying an effective amount of said coating dispersion onto said substrates to form a film coating on said substrates, and drying the film coating on said substrates.
