Abstract:
An emulsion comprising:(a) from about 0.3% to about 15% by weight, based on the total weight of the emulsion, of an emulsification system comprising: i) from about 0.1% to about 8% by weight, based on the total weight of the emulsion, of a cationic surfactant; ii) a from about 0.1% to about 8% by weight, based a on the total weight of the emulsion, of an anionic surfactant; iii) from about 0.1% to about 8% by weight, based on the total weight of the emulsion, of a bridging surfactant; (b) from about 3% to about 70% by weight, based on the total weight of the emulsion, of an oil; and (c) from about 15% to about 97% by weight, based on the total weight of the emulsion, of water; wherein the emulsion is stable for at least 30 days at 25Â° C. in the absence of auxiliary co-emulsifiers.
