Laundry detergent composition containing a transition metal bleaching catalyst

The present research disclosure describes laundry detergent- and laundry bleach compositions containing the transition metal complex of the formula (1):

(1)

These compound of formula (1) catalyze bleaching processes with peroxides, present in the laundry detergent- or laundry bleach composition.

The detergent composition disclosed comprise:

i) 5-70% of an anionic surfactant and/or a nonionic surfactant;

ii) 5-70% of a builder;

iii) 0.5-30% of a peroxide;

iv) 0.01-1% of the compound of formula (1);

v) 0-3% of a polymeric dye transfer inhibition agent;

vi) 0-5% of at least one enzyme selected from the group consisting of cellulase, protease, amylase and lipase; and

vii) 0-10% of a peroxide activator.

Further, a laundry additive composition for bleaching and/or disinfecting is disclosed comprising:

i) 0-20% of an anionic surfactant and/or a nonionic surfactant;

ii) 0-60% of a builder;

iii) 1-99% of a peroxide;

iv) 0.005-2% of the compound of formula (1);

v) 0-5 % of a peroxide activator

vi) 0-5% of at least one enzyme selected from the group consisting of cellulase, protease, amylase and lipase; and

In general, amounts given in percent are to be understood as being percent by weight, based on the total weight, unless otherwise stated.

The detergent or bleaching laundry additive may be formulated as a solid, as an aqueous liquid comprising, e.g., 5-50, preferably 10-35% water or as a non-aqueous liquid detergent, containing not more than 5, preferably 0-1 wt.% of water, and based on a suspension of a builder in a non-ionic surfactant, as described, e.g., in GB-A-2158454.

The anionic surfactant component may be, e.g., an alkylbenzenesulfonate, an alkylsulfate, an alkylethersulfate, an olefinsulfonate, an alkanesulfonate, a fatty acid salt, an alkyl or alkenyl ether carboxylate or an a-sulfofatty acid salt or an ester thereof. Preferred are alkylbenzenesulfonates having 10 to 20 carbon atoms in the alkyl group, alkylsulfates having 8 to 18 carbon atoms, alkylethersulfates having 8 to 18 carbon atoms, and fatty acid salts being derived from palm oil or tallow and having 8 to 18 carbon atoms. The average molar number of ethylene oxide added in the alkylethersulfate is preferably 1 to 20, preferably 1 to 10. The salts are preferably derived from an alkaline metal like sodium and potassium, especially sodium. Highly preferred carboxylates are alkali metal sarcosinates of formula

R-CO(R1)CH2COOM1 in which R is alkyl or alkenyl having 9-17 carbon atoms in the alkyl or alkenyl radical, R1 is C1-C4 alkyl and M1 is alkali metal, especially sodium.

The nonionic surfactant component may be, e.g., primary and secondary alcohol ethoxylates, especially the C8-C20 aliphatic alcohols ethoxylated with an average of from 1 to 20 moles of ethylene oxide per mole of alcohol, and more especially the C10-C15 primary and secondary aliphatic alcohols ethoxylated with an average of from 1 to 10...
