  • Patent number: 6025311
    Abstract: A stable fluid polymer suspension is composed of at least one water soluble polysaccharide polymer in an aqueous carrier fluid in which the polysaccharide polymer does not significantly swell or dissolve where the polysaccharide polymer in the aqueous carrier fluid has the measured properties of:i) rendering the polymer(s) insoluble, resulting in a cloudy dispersion,ii) limiting the swelling of insolubilized polymer(s), leading to a polymer sediment volume of a 1 weight percent polymer dispersion to less than 1%, andiii) preventing phase separation for at least one week.This invention also Includes a method of preparing the stable fluid polymer suspension having the above mentioned measured properties. The stable aqueous fluid suspension of this invention is a clear, odorless, and stable formulation and is used in cosmetics, personal care, and household products.
