  • Composition and process for gelatin-free soft capsules
    Patent number: 5342626
    Abstract: The present invention relates to a polymer composition comprised of gellan, carrageenan and mannan gums and a process for producing flexible films for encapsulation comprising the gellan, carrageenan and mannan gum composition. The mannan gums include the galactomannans and the glucomannans. Advantageously, soft capsules of the above composition are produced using the novel process. The composition comprises a blend of a gellan gum: (carrageenan/mannan gum) wherein the gellan gum concentration ranges from about 0.1 to 50 weight percent and the ratio of carrageenan/locust bean gum ranges from 3:1 to 1:3. Additional reagents are added to this gum blend to form a film-forming polymer composition useful in the production of gelatin-free capsules or microcapsules.

  • Composition and method for rheology controlled printing of fabric and carpet
    Patent number: 5153317
    Abstract: A composition and its method of use are disclosed for controlling rheology of an aqueous dye, which composition comprises 1-30 parts of a gum selected from the group consisting of xanthan gum, rhamsan gum, welan gum and mixtures thereof and 70-99 parts of a water soluble polysaccharide having aliginate equivalent rheology, preferably an alginate. Also disclosed is a color imparting composition for fabric or carpet printing which comprises 99-99% of an aqueous dye component and 1-10% of the rheology control component. The polysaccharide is preferably an alginate, starch, cellulosic polymer or guar gum or mixtures thereof.

  • Film-forming size composition
    Patent number: 5079348
    Abstract: A film forming composition useful as a paper size is described which includes 1-20 parts, preferably 2-15 parts, by weight of a gum selected from the group consisting of xanthan gum, rhamsan gum, welan gum and mixtures thereof; 3-20 parts, preferably 5-17 parts, by weight of a water soluble alginate; and 60-100 parts, preferably 70-90 parts, by weight of starch, polyvinyl alcohol or carboxymethylcellulose, with the gum:alginate ratio being not greater than 1:1, preferably not greater than 1:2. The balance of the composition will primarily be water. Additives such as sodium hexametaphosphate may also be present.
