Abstract

Abstract An improved cosmetic lotion having desirable rheology is disclosed as comprising a dissolved mannogalactan gum and as a dispersed phase swollen hydrated particles of algin salt containing cations selected from the group consisting of calcium and aluminum. The ratio by dry weight of the algin salt to the gum is from about 5:1 to about 3:1 and desired rheology is obtained by controlling the cation content selected from the group calcium and aluminum relative to the content of the algin salt so that the viscosity of the lotion at 25* C. is from about 5,000 to about 20,000 cps. when the concentration of the algin salt in the lotion is from about 0.5 percent to about 1.1 percent. The gum concentration is from about 0.14 percent to about 0.24 percent. The lotion may contain beneficiating materials such as glycerine and alcohol. It preferably contains boric acid which has a modifying effect on the gum and, in addition, an acid such as fumaric. The invention relates to the lotion and for use in making it a solid composition and a glycerine base slurry. Its production involves equilibrating cation concentration from suitable cation sources for obtaining desired rheology.
