Carrageenan products and method for their production and use

摘要

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.

主权项

1. A toothpaste composition comprising a binder, an abrasive, a humectant, a foaming agent, and water, said binder comprising a carrageenan product comprising a semi-refined, alkali treated iota carrageenan, wherein said 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 sodium cation content of at least 35%, wherein said sodium cation content is determined by the weight of sodium cations divided by the sum of the weight of sodium cations and potassium cations in said semi-refined, alkali treated iota carrageenan; and wherein said toothpaste composition tested on twelve week stability tests at 40° C. has Cuban values of from 3-9 and viscosity of from 15-40 torque %.
