DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to laundry detergent compositions containing amine detersive surfactants and specially selected perfume components which reduce the malodor of the amine.
BACKGROUND OF THE INVENTION
It has long been known that certain amines are effective detergent surfactants. However, a problem associated with many amines is an unattractive odor resembling fish which remains present in detergent compositions containing the amine and even in fabrics which have been washed with the amine-containing detergent.
It has now been found that including a certain amount of specially selected perfume components in the laundry detergent can markedly reduce or eliminate this malodor.
SUMMARY OF THE INVENTION
The present invention concerns laundry detergent compositions comprising: amine detersive surfactant; perfume component selected to have the following characteristics: non-amine detersive surfactants selected from anionic, nonionic, ampholytic, cationic, zwitterionic, and mixtures thereof.
These perfume components act to reduce the malodor associated with amine surfactants. Preferably the perfume components is selected from the group consisting of dodecahydro-3a,6,6,9A-tetramethylnaphtho (2,1-B) furan, 3,3-dimethyl-5-(2,2,3 trimethyl-3 cyclopenten-1-yl)-4 pentenol, methyl ionone, cis 3 hexenyl iso butyrate, undecalatone, phenyl ethyl phenyl acetate, hexyl-ortho-hydroxbenzoate, and mixtures thereof; and
The compositions of this invention preferably further comprise a performance enhancing amount of a detergent-compatible enzyme selected from the group consisting of protease, lipase, amylase, cellulase, peroxidase, and mixtures thereof.
All parts, percentages and ratios used herein are expressed as percent weight unless otherwise specified. All documents cited are, in relevant part, incorporated herein by reference.
DESCRIPTION OF THE INVENTION
The laundry detergent compositions herein comprise an effective amount of a perfume component which acts to reduce the malodor associtated with the amine surfactant. By "effective amount" means an amount sufficient to reduce the amine-type odor of the detergent compositions. Preferably, the detergent compositions herein will comprise from about 0.00001% to about 5, more preferably about 0.00001% to about 2%, most preferably about 0.0001% to about 0.5%, by weight, of specially selected perfume components. The perfume components which have been found to reduce the amine malodor are those with a low solubility in water, i.e., they have a partition coefficient value, (clogP), equal to or higher than 2.0, at standard conditions of 25.degree. C. and 760 mm Hg in a water/octanol system. Additionally the perfume components of this invention should have a boiling point greater than 200.degree. F. The perfume components also have a unique property of having a low odor detection threshold (ODT) lower than about 300 PPB, preferably equal to or lower than about 0.1 PPB. These parameters are fully explained in "Compilation of Odor and Taste Threshold Value Data. (ASTM DS 48 A)". Edited by F. A. Fazzalari, International Business Machines, Hopewell Juntion, N.Y.
Examples of preferred perfume components are those selected from the group consisting of dodecahydro-3a,6,6,9A-tetramethylnaphtho (2,1-B) furan, 3,3-dimethyl-5-(2,2,3 trimethyl-3 cyclopenten-1-yl)-4 pentenol methyl ionone, cis 3 hexenyl iso butyrate, undecalatone, phenyl ethyl phenyl acetate, hexyl-ortho-hydroxybenzoate, and mixtures thereof.
It is preferred that the specially selected perfume components herein be mixed together prior to addition to the laundry detergent composition. These perfume components may be combined with other perfume ingredients before addition to the composition.
The perfume containing these specially selected perfume components is preferably sprayed onto the final granular detergent composition or mixed into the final liquid laundry detergent in a manner which does not adversely affect the perfume.
The amine--Although certain amines are effective surfactants, when present i
