20110159059 | Oral Care Beadlets - A single unit oral care product comprises an oral care composition comprising a polysaccharide, a secondary polymer, and a sequestrant where an outer surface of the oral care composition is encapsulated by an outer coating comprising the polysaccharide in cross-linked form. The single unit oral care product may be made by combining the gellable polysaccharide, the secondary polymer, and the sequestrant to form an oral care composition and forming at least a portion of the oral care composition into a shaped unit. The shaped unit is then immersed in an aqueous solution of a divalent salt to form a gelled oral care composition. Optionally, the gelled oral care composition may be washed with a second sequestrant. | 06-30-2011 |
20120189559 | Carrageenan Products and Method for Their Production and Use - The present invention is directed to a carrageenan product comprising a semi-refined, alkali treated iota carrageenan wherein the semi-refined, alkali treated iota carrageenan has: (i) a viscosity of 18 cP to 83 cP, (ii) a particle size of at least 90% passing through a #100 US sieve mesh and at least 20% passing through a #230 US sieve mesh, and (iii) a fraction of sodium cations of at least 35%, wherein the fraction of sodium cations is determined by the weight of sodium cations divided by the sum of the weight of sodium cations and potassium cations. This invention is also directed to toothpaste compositions comprising the carrageenan product of the invention. | 07-26-2012 |
20120189561 | Toothpaste Composition - The present invention is directed to a toothpaste composition comprising a binder, an abrasive, a foaming agent, water, and polyethylene glycol, wherein the binder comprises semi-refined carrageenan. The toothpaste composition has improved shelf life. | 07-26-2012 |
