- Example 10 Formulation 10 of the coating film Example 11. Formulation 11 of the coating film
- Example 18 shows the viscosities of a number of commonly used coatings and also those of some coatings that include Isomalt in their composition. It is evident that some formulations containing Isomalt can allow its preparation in concentrations from 35% solids content or higher.
- Example 18 the viscosities were determined with a Brookfield-type viscometer, W&J Instrument Co. Model RV-2M brand. Considering that coating dispersions are generally non-Newtonian type fluids, where the measured viscosity depends on of the measurement conditions, the needle and its rotational speed are shown in square brackets when carrying out the respective measurement.
- Example 19 shows the gloss of films with formulations that do not include Isomalt, compared to the gloss of compositions with Isomalt-added film-forming polymers. Measurements were made with the KSJ brand Glossmeter instrument, model MG6-SA with a 60o angle of incidence. It is evident that the inclusion of Somali promotes increased brightness in movies, increasing on average by 15 GU, increasing brightness by more than 300%. In order for the comparisons to be objective without intervention of the color factor, the gloss was determined on white colored films.
- Example 20 shows the glossiness of films of compositions where only one smoker is involved. It can be seen that the Isomalt component alone generates greater brilliance, however, when comparing with the results of table 19, a synergy effect is observed where the brilliance of coatings of mixtures of film-forming agents mixed with Isomalt is greater. than the brilliance generated by any of the individually tested filmmakers.
- Example 20 Applied Film Gloss Measurement Comparison Table
- Optimal coating processing conditions ie those required to apply a thin-film film on tablets, granules, pellets or capsules, are dependent on the composition of the film.
- compositions that include Isomalt as an ingredient it has been found that, in some cases, the optimum application temperature ranges are broader, this signifying an advantage, given that many substrates, due to instability or various causes, can require to be processed at relatively low temperatures.
- the table in Example 21 shows optimal application temperature ranges for various types of film coating formulations. It is noteworthy that some of the compositions that include isomait can be applied at moderately lower temperatures than traditional coatings.
- Example 21 Comparison table of optimum process temperatures in coating application. Tablet bed temperature
- the term "increased gloss” refers to the gloss exhibited by the coating film and is in the range of 10 to 30 or more Gloss Units (GU), measured with a KSJ brand Glossmeter instrument, model MG6-SA with a 60o angle of incidence.
- GUI Gloss Units
- Isomalt or “isomaitulose derivative” are used interchangeably and refer to the mixture of 6-O-a-D-gluopyranosyl-D-mannitol dihydrate with 6-O-a-D-glucopyranosyl-D-sorbitol.
- film-forming polymer is used interchangeably as film-forming or adherent polymer to denote polyvinyl alcohol, Hypromellose, ethylene glycol and vinyl alcohol graft copolymer, with polyvinyl alcohol, copovidone, polyvinyl alcohol, methacrylate derivatives, Isomalt and cellulosic derivatives
