Abstract
This disclosure relates to a method for making a dispersion, comprising preparing an aqueous phase comprising water and a surfactant; combining a hydrophobic substance and a plurality of particles comprising cellulose to form a concentrate; and mixing the aqueous phase and concentrate to provide a dispersion. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
Claims18
A method for making a dispersion, the method comprising:
- (a) preparing an aqueous phase comprising water and a surfactant in an amount of from 30 to 40 wt % based on the total weight of the aqueous phase, wherein the surfactant is a sulfate, sulfonate, isethionate, carboxylate, sarcosinate, amino acid-based surfactant, non-ionic surfactant, soap, sulfoacetate, or a combination thereof;
- (b) preparing a hydrophobic phase at ambient temperature, wherein the hydrophobic phase comprises:
- comprising
- (i) a hydrophobic substance in an amount of from 40 to 60 wt % based on the total weight of the hydrophobic phase,
- (ii) water in an amount of from 20 to 50 wt % based on the total weight of the hydrophobic phase, and
- (iii) a plurality of particles comprising cellulose in an amount of from 20 to 30 wt % based on the total weight of the hydrophobic phase,
- wherein the hydrophobic substance comprises an oil, a silicone, a fat, an emollient, a triester of glycerol, or a combination thereof, and
- wherein the particles have:
- (i) a mean particle size of from about 0.1 to about 100 microns;
- (ii) an aspect ratio of from about 1 to about 1.5;
- and
- (iii) a non-spherical shape,
- wherein at least a portion of the cellulose is type-II cellulose, thereby providing a concentrate;
- and
- (c)-mixing the aqueous phase and the concentrate at ambient temperature, thereby providing the dispersion.
