Water-Soluble Cellulose Derivatives Uses as Primary Emulsifyinga Gents. Part 1

Abstract

Abstract The ability of methyl-, methylethyl-, and sodium carboxymethyl-cellulose to promote emulsions with liquid paraffin and arachis oil is largely independent of the viscosity of their mucilages. Methyl- and methylethyl-cellulose are more efficient emulsifying agents than is sodium carboxymethylcellulose. Emulsifying efficiency increases with the concentration of the derivative, and low viscosity grades are more efficient than high viscosity grades. Mixtures of these derivatives have little advantage as emulsifying agents over methyl- and methylethyl-cellulose used singly.
