Abstract
Low concentration surfactant emulsions and methods of making and using the same are disclosed herein. The emulsions have the benefit of employing less surfactant than conventional emulsions. Further, the emulsions are dilutable and retain their stability upon dilution. A benefit of the emulsions is that they leave a low residue, preferably no residue, on a surface after contact.

A composition comprising:
- a carrier, an alkalizing agent, and an emulsion in the carrier, wherein the emulsion comprises a hydrophobic component and a surfactant and the carrier comprises water,
- wherein the surfactant forms an interfacial film;
- wherein the surfactant is present in a concentration between about 0.1 wt. % and about 1 wt. % of the composition, wherein the surfactant comprises a cross-linked copolymer of acrylic acid C10-C30 alkyl acrylate;
- and
- wherein the surfactant has an HLB of at least about 6;
- wherein the carrier is present in an amount between about 80 wt. % and about 98 wt. % of the composition;
- wherein the hydrophobic component is in a concentration between about 0.1 wt. % and about 5 wt. % and comprises an oil;
- wherein the oil comprises mineral oil;
- between about 0.01 wt. % and about 5 wt. % of the alkalizing agent;
- wherein the emulsion encapsulates a fragrance, a dye, or a mixture thereof;
- and
- wherein the emulsion is stable at temperatures between about 10° C. and about 40° C. and stable for 24 hours upon dilution within the composition.
