Abstract
The present invention relates to bleaching and detergent compositions comprising conventional detergent ingredients, bleaching systems with one or more bleach activators. Preferred bleaching activators are amido-derived bleach activators and/or N-acyl caprolactam bleach activators. The invention also relates to methods of using the detergent compositions.
Claims30
A bleaching system composition comprising at least about 0.1% by weight of a peroxygen bleaching compound capable of yielding hydrogen peroxide in an aqueous liquor and at least 0. 1% by weight of one or more bleach activators, wherein said bleach activators are members selected from the group consisting of:
- a) a bleach activator of the general formula:
- ##STR16## or mixtures thereof, wherein R.sup.1 is an alkyl, aryl, or alkaryl group containing from about 1 to about 14 carbon atoms, R.sup.2 is an alkylene, arylene or alkarylene group containing from about 1 to about 14 carbon atoms, R.sup.5 is H or an alkyl, aryl, or alkaryl group containing from about 1 to about 10 carbon atoms, and L is a leaving group selected from the group consisting of:
- ##STR17## and mixtures thereof, wherein R.sup.1 is an alkyl, aryl or alkaryl group containing from about 1 to about 14 carbon atoms, R.sup.3 is an alkyl chain containing from 1 to about 8 carbon atoms, R.sup.4 is H or R.sup.3, and Y is H or a solubilizing grou selected from the group consisting of:
- --SO.sub.3.sup.- M.sup.+, --CO.sub.2.sup.- M.sup.+, --SO.sub.4.sup.4 M.sup.4, --N.sup.+ (R.sup.3).sub.4 X.sup.- and O<--N(R.sup.3).sub.3 wherein R.sup.3 is an alkyl chain containing from about 1 to about 4 carbon atoms, M is a cation which provides solubility to the bleach activator and X is an anion which provides solubility to the bleach activator;
- b) a benzoxazin bleach activator of the formula:
- ##STR18## wherein R.sub.1 is H, alkyl, alkaryl, aryl, arylalkyl, and wherein R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are the same or different substituents selected from H, halogen, alkyl, alkenyl, aryl, hydroxyl, alkoxyl, amino, alkylamino, --COOR.sub.6, wherein R.sub.6 is H or an alkyl group and carbonyl functions;
- c) a N-acyl caprolactam bleach activator of the formula:
- ##STR19## wherein R.sup.6 is H or an alkyl, aryl, alkoxyaryl, or alkaryl group containing from 1 to 12 carbons provided that said N-acyl caprolactam activator comprises a hydrophilic N-acyl caprolactam activator where R.sup.6 contains from about 1 to about 6 carbon atoms and a hydrophobic N-acyl caprolactam activator where R.sup.6 contains at least 6 carbon atoms wherein said hydrophilic and hydrophobic are different N-acyl caprolactam activators;
- and
- d) mixtures of a), b) and c).
A detergent composition comprising:
- a) at least about 0.001% of enzymes selected from the group consisting of proteases, amylases, lipases, cellulases, peroxidases and mixtures thereof;
- and
- b) a bleaching system comprising at least about 0.1% by weight of a substantially insoluble organic peroxyacid having the general formula:
- ##STR23## wherein R.sup.1 is an alkyl, aryl, or alkaryl group containing from about 1 to about 14 carbon atoms, R2 is an alkylene, arylene or alkarylene group containing from about 1 to about 14 carbon atoms, R.sup.5 is H or an alkyl, aryl, or alkaryl group containing from about 1 to about 10 carbon atoms.
A bleaching system composition comprising at least about 0.1% by weight of a peroxygen bleaching compound capable of yielding hydrogen peroxide in an aqueous liquor and at least 0.1% by weight of one or more bleach activators selected from the group consisting of:
- nonanoyl caprolactam, 3,5,5-trimethylhexanoyl caprolactam, decanoyl caprolactam, undecenoyl caprolactam, nonanoyl caprolactam, (6-octanamidocaproyl)oxybenzenesulfonate, (6-nonanamidocaproyl) oxybenzenesulfonate, (6-decanamidocaproyl)oxybenzenesulfonate and mixtures thereof.
