Abstract
The invention provides a concentrated, dilutable cleaning composition which comprises a novel microemulsion comprising a nonionic surfactant oil phase, a predominant, aqueous continuous phase, a polar organic solvent coupling agent, and a combination of surfactants different from the surfactant oil phase as the dispersing agent facilitating formation of the microemulsion.
Claims18
A concentrated, dilutable cleaning composition which comprises a microemulsion comprising a nonionic surfactant oil phase, a predominant, aqueous continuous phase, a polar organic solvent coupling agent, and a combination of surfactants different from the surfactant oil phase as the dispersing agent facilitating formation of said microemulsion, said cleaning composition characterized by exhibiting the feature of blooming upon dilution with water in the absence of a lipophilic oil other than a nonionic surfactant.
A concentrated, dilutable cleaning composition of a clear microemulsion comprising:
- a. an oil phase consisting essentially of a nonionic surfactant, said oil phase dispersed in a predominant, aqueous continuous phase;
- b. at least one polar organic solvent coupling agent;
- and
- c. at least two additional surfactants different from the surfactant of said oil phase, said additional surfactants being the dispersing agent facilitating formation of said microemulsion, said cleaning composition characterized by exhibiting the feature of blooming upon dilution with water in the absence of a lipophilic oil other than a nonionic surfactant.
A concentrated, dilutable cleaning composition of a clear microemulsion comprising:
- a. at least about 60% wt. water, said water being part of a predominant aqueous continuous phase;
- b. about 0.1-25% wt. of a first nonionic surfactant with an HLB of less than about 10, said first nonionic surfactant effectively constituting a sparingly soluble to essentially water insoluble oil phase;
- c. about 0.01-5% wt. of an anionic surfactant;
- d. about 0.05-10% wt. of a second nonionic surfactant having an HLB of greater than 10, the ratio of the total of the first and second nonionic surfactants to the anionic surfactant at least greater than 1:1, the anionic surfactant and the second nonionic surfactant being a dispersing agent for the first nonionic surfactant oil phase;
- and
- e. about 0-25% of a coupling agent comprising a polar organic solvent, said cleaning composition characterized by exhibiting the feature of blooming upon dilution with water in the absence of a lipophilic oil other than a nonionic surfactant.
