Claims
- 1. A fluid cleaning composition comprising:a) a tertiary amine oxide having the formula: wherein R1 is a C10-C25 linear or branched alkyl group, and R2 and R3 are independently selected from C1-C4 alkyl groups and C2-C4 hydroxy alkyl groups;b) an alkyl ethoxy sulfate surfactant; c) a diamine; and d) optionally, a detergent adjunct ingredient wherein the molar ratio of amine oxide (a) to surfactant (b) is from about 5:4 to about 9:1.
- 2. The composition according to claim 1 wherein said composition is substantially free of halide bleaching agents.
- 3. The composition according to claim 1 wherein the composition further comprises a solvent.
- 4. The composition according to claim 3 wherein the solvent comprises butoxy propoxy propanol.
- 5. The composition according to claim 1 wherein the composition comprises from about 0.01% to about 20% by weight of the composition of the amine oxide.
- 6. The composition according to claim 1 wherein the composition comprises from about 0.01% to about 5% by weight of the composition of the surfactant.
- 7. The composition according to claim 1 wherein the composition further comprises magnesium ions.
- 8. The composition according to claim 1 wherein said molar ratio of the amine oxide to the surfactant is from about 3:2 to about 5:1.
- 9. The composition according to claim 1 wherein in said R2 and R3 and C1-C2 alkyl and R1is C12-C18 alkyl.
- 10. The composition according to claim 1 further comprising an anionic surfactant selected from the group consisting of alkyl sulfate, alkyl ethercarboxylates, methyl ester sulfonates, and alkyl glycerol sulfonates and mixtures thereof.
- 11. The composition according to claim 10 wherein said anionic surfactant is selected from alkyl sulfates.
- 12. The composition according to claim 1 wherein said detergent adjunct ingredient is selected from the group consisting of water, solvents, chelants, malodor control agents, and silicone wetting agents.
- 13. The composition according to claim 1 wherein the diamine comprises a low molecular weight organic diamine having a pK1 and a pK2, wherein the pK1 and the pK2 of said diamine are both in the range of from about 8.4 to about 11.5.
- 14. The composition according to claim 13 wherein the diamine is selected from the group consisting of: wherein R1-4 are independently selected from H, methyl, ethyl, and ethylene oxides; Cx and Cy are independently selected from methylene groups or branched alkyl groups where x+y is from about 3 to about 6; and A is optionally present and is selected from electron donating or withdrawing moieties chosen to adjust the diamine pKa's to the desired range; wherein if A is present, then x and y must both be 1 or greater.
- 15. The composition according to claim 13 wherein said diamine is selected from the group consisting of:Dimethyl aminopropyl amine 1,6-Hexane diamine 1,3-Propane diamine 2-Methyl 1,5-pentane diamine 1,3-Pentadiamine 1-Methyl-diaminopropane or 1,3-Diaminobutane 1,2-bis(2-aminoethoxy)amine Isophorone diamine 1,3-bis(methylamine)-cyclohexane or 1,3-cyclohexanebis(methylamine) and mixtures thereof.
- 16. The composition according to claim 15 wherein said diamine is 1,3-cyclohexanebis(methylamine).
