Description

Liquid cleaning compositions

Description The present invention relates to a process for preventing the reduction of hydrogenperoxide or a precursor of hydrogen peroxide during storage in liquid cleaning compositions, like bleach boosters, detergents, washing or pre-treatment compositions. Further aspects of the invention are liquid cleaning compositions containing hydrogenperoxide or a precursor of hydrogen peroxide, an acylhydrazone compound and a polyalkylene glykol derivative and the use of an acylhydrazone compound together with a polyalkylene glykol derivative in a liquid cleaning composition containing hydrogenperoxide or a precursor of hydrogen peroxide. The liquid compositions essentially cause no spotting.

Today's commercial liquid detergents are formulated without hydrogenperoxide or a precur- sor of hydrogen peroxide because these would be rapidly destroyed in the aqueous medium and other ingredients, such as fragrants or enzymes would be oxidised under these conditions. Hitherto, liquid bleach boosters are only formulated at low pH (pH 3.0 or lower) and only in absence of any bleach activators or catalysts due to similar stability constraints as described above for the liquid detergents.

It has been an object of the instant invention to provide a liquid cleaning composition having an improved stability. That is, the hydrogenperoxide content should remain ideally unchanged after storage for several days even at elevated pH as well as other components, such as bleach catalysts.

Using liquid detergent formulations in household laundry processes it is desirable achieving a high uptake of the active ingredients. The active ingredients should, however, not exhaust in localized (micro)spots. The concentration should be equally distributed over the fabric. This feature is often called levelling property. A good levelling property means that there is no or almost no spectroscopic difference between a spot and the surrounding/background. The extent of leveling depends not only on the way of pre-treatment but also on the detergent formulation, the washing conditions, concentration levels, affinity/substantivity and the kind of active ingredients. A good levelling property is a prerequisite to avoid spotting or staining on the fabrics which may otherwise be caused.

Very commonly, in particular liquid detergents and especially pre-treatment formulations are directly applied on the fabric by the consumer without prior dilution. Due to this consumer habit undesired localized accumulation may occur on the fabric. The instant composition and process avoid also this negative effect. This is particularly important since local spots of, for example, hydrogen peroxide could even lead to a damage of the fibres.

At present it is almost impossible to use a bleach catalyst together with hydrogen peroxide or a precursor of hydrogen peroxide in liquid cleaning compositions, especially at pH values high enough to be applied in the washing machine to exhibit reasonable bleach perfor- mance. It has now been found that liquid cleaning compositions containing hydrogenperoxide or a precursor of hydrogen peroxide, an acylhydrazone compound and a polyalkylene glykol derivative exhibit almost no reduction in peroxide content when stored for a considerable time.

The bleach activity after storage remains almost unchanged compared to the initial bleach activity and essentially no spotting occurs.

Preferably, however, inorganic peroxides are used, for example persulfates, perborates, percarbonates and/or persilicates.

Examples of suitable inorganic peroxides are sodium perborate tetrahydrate or sodium per- borated monohydrate, sodium percarbonate, inorganic peroxyacid compounds, such as for example potassium monopersulphate (MPS). If organic or inorganic peroxyacids are used as the peroxygen compound, the amount thereof will normally be within the range of about 2-30 wt-%, preferably from 4-30 wt-%.

The organic peroxides are, for example, mono- or poly-peroxides, urea peroxides, a combination of a Ci-C4alkanol oxidase and Ci-C4alkanol (such as methanol oxidase and ethanol as described in WO95/07972), alkylhydroxy peroxides, such as cumene hydroperoxide and t-butyl hydroperoxide.

The peroxides may be in a variety of crystalline forms and have different water contents, and they may also be used together with other inorganic or organic compounds in order to improve their storage stability. All these peroxy compounds may be utilized alone or in conjunction with an organic bleach catalyst not containing a transition metal. Generally, the bleaching composition of the invention can be suitably formulated to contain from 0.1 to 30 wt-%, of the peroxy bleaching agent.

As oxidants, peroxo acids can also be used. One example is organic mono peracids of for- O

Instead of the peroxy acid it is also possible to use organic peroxy acid precursors and H2O2. Such precursors are the corresponding carboxyacid or the corresponding carboxy- anhydrid or the corresponding carbonylchlorid, or amides, or esters, which can form the peroxy acids on perhydrolysis. Such reactions are commonly known.

Peroxyacid bleach precursors are known and amply described in literature, such as in the British Patents 836,988; 864,798; 907,356; 1 ,003,310 and 1 ,519,351 ; German Patent

(a) subtilisins (EC 3.4.21.62), including those derived from Bacillus, such as Bacillus lentus, B. alkalophilus, B. subtilis, B. amyloliquefaciens, Bacillus pumilus and Bacillus gibsonii as described in U.S. Pat. No. 6,312,936 B1 , U.S. Pat. No. 5,679,630, U.S. Pat. No. 4,760,025, U.S. Pat. No. 7,262,042 and WO09/021867. The main representatives are the subtilisins from Bacillus amyloliquefaciens (called BPN') and Bacillus licheniformis (called subtilisin Carlsberg), the serine protease PB92, subtilisin 147 and/or 309 (sold under the trade name Savinase® by Novozymes A / S, Bagsvaerd , Denmark) and subtilisin from Bacillus lentus, especially from Bacillus lentus (DSM 5483) and each of the variants available via mutagen- esis of these enzymes Examples as described in WO 89/06276 and EP 0 283 075, WO 89/06279, WO 89/09830, WO 35 89/09819 and W09106637. Proteases of the subtilisin type (subtilases, subtilopeptidases, EC 3.4.21.62, valid as of September 9, 2014) are classed as belonging to the serine proteases, due to the catalytically active amino acids. They are naturally produced and secreted by microorganisms, in particular by Bacillus species. They act as unspecific endopeptidases, i.e. they hydrolyze any acid amide bonds located inside peptides or proteins. Their pH optimum is usually within the distinctly alkaline range. A review of this family is provided, for example, in the paper "Subtilases: Subtilisin-like Proteases" by R. Siezen, pages 75-95 in "Subtilisin enzymes", edited by R. Bott and C. Betzel, New York, 1996. Subtilisins are suitable for a multiplicity of possible technical uses, in particular as ac- tive ingredients of detergents or cleaning agents. The class of serine proteases share a common amino acid sequence defining a catalytic triad which distinguishes them from the chy- motrypsin related class of serine proteases.

(b) trypsin-type or chymotrypsin-type proteases, such as trypsin (e.g., of porcine or bovine origin), including the Fusarium protease described in WO 89/06270 and the chymotrypsin proteases derived from Cellumonasas described in WO 05/052161 and WO05/052146. The subtilisins and chymotrypsin related serine proteases both have a catalytic triad comprising aspartate, histidine and serine. In the subtilisin related proteases the relative order of these amino acids, reading from the amino to carboxy terminus is aspartate-histidine-serine. In the chymotrypsin related proteases the relative order, however is histidine-aspartate-serine. Thus, subtilisin herein refers to a serine protease having the catalytic triad of subtilisin related proteases.

(c) metalloproteases, including those derived from Bacillus amyloliquefaciens described in WO 07/044993A2., neutralprotease NprE (EC:3.4.24.28) described in US 201 1/0104786 A1 and proteinase T (Thermolysin) described in EP 2205732 A2 (Danisco US Inc., now DuPont Nutrition & Health).
