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.
Abstract:
The present invention discloses a novel film coating composition of polyvinyl alcohol (PVA) in combination with sugar, and a plasticizer or a combination of plasticizers resulting in a composition which is non tacky and easily dispersible in water at high solids content. The coating compositions help in achieving higher spray rates, disperse in less solvent i.e water, and helps in reduction of coating process time. Further the resultant film which when coated onto substrates exhibits good adhesion and provides smooth surface to substrates.
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:
A coating composition based on sodium alginate, is designed to release the active ingredient of pharmaceutical substances, veterinary substances, nutraceutical products, and food and confectionery products after a pre-determined lag period, and a method of preparing the coating composition is also provided.
Abstract:
A dry moisture barrier film coating composition for forming a moisture barrier film coating for pharmaceutical tablets and the like comprises polyvinyl alcohol, self emulsifying glyceryl monostearate, and optionally a flow aid, a colorant, a plasticizer, a flavoring agent and/or a sweetening agent. 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 dry film coating composition and a method for preparing the same. The coating composition comprises a polymer, a waxy emulsifier, a plasticizer, a wetting agent, a hydrophobic agent and optionally other pharmaceutically acceptable excipients such as opacifier, pigment, diluent, lubricant, flavoring agent, sweetener, and the like. The coating composition is used for coating of substrate such as pharmaceutical tablet, nutritional supplement, food, confectionery forms, agricultural seed, and the like.
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.
