Definitions

• a detergent composition comprising a water-soluble organic anionic (soap or non-soap) or nonionic detergent compound, a water-soluble inorganic oxygen-releasing per compound, a fluorescer which is a derivative of 1,3-diphenyl 'A -pyrazoline, and diethylene triamine pen'taacetic acid to reduce substantially the loss of fluorescer due to the oxidative degradation thereof by the per compound.
• This invention relates to detergent compositions which contain a synthetic detergent and/or a soap, an oxygenreleasing per compound, and a fluorescent brightening agent which is a derivative of 1,3-diphenyl A -pyrazoline. It is especially concerned with particulate compositions.
• X and Y are H, lower alkyl, aryl, CF F, --Cl, Br, CN, SO NH CO R, SO R, CO2NR1R2 0r '-SO2NR1R2 Where R is H, lower alkyl or aryl; and R and R are hydrogen, lower alkyl or aryl.
• these detergent compositions have been unstable both in storage and in use. They have shown a loss in fluorescer content in storage and in use with consequential loss in fabric whitening effect. This loss has been found to be due to the oxidation of the fluorescer by the per compound to give the corresponding pyrazole which is then further oxidised.
• This invention provides a synthetic detergent and/ or soap composition in which the loss of fluorescer is reduced.
• the present invention provides a composition
• a composition comprising -a synthetic detergent and/or a soap, a brightening agent which is a derivative of 1,3-diphenyl A pyrazoline, an oxygen releasing per compound and, as an additive to reduce the loss of the pyrazoline, diethylene triamine penta acetic acid.
• Particularly convenient pyraozoline fluorescers are 1- p sulphonamidophenyl) 3 (p chlorophenyl) A pyrazoline (referred to hereafter as A), l-(p-carboxymethyl phenyl) 3 (p chlorophenyl) A pyrazoline (referred to hereafter as B) and 1-(m-chlorophenyl)-3- p-acety laminophenyl) A pyrazoline (referred to hereafter as compound C).
• fluorescers may be .present in the detergent compositions at concentrations varying from 0.01% to 0.05%.
• Suitable per compounds are alkali metal perborates and alkali metal per carbonates, e.g. sodium perborate and sodium percarbonate. Hydrogen peroxide may be used in liquid formulations.
• detergent compositions may be present in the detergent compositions at concentrations varying from l-50%, preferably 10-20% by weight of the total composition.
• the concentration of diethylene triamine pent-a acetic acid (DETPA) to be used in the compositions depends on the degree of stabilisation required of the composition, the amount and stability of the per compound present and the storage conditions likely to be encountered.
• compositions lose their fluorescer more rapidly when stored under climatic conditions of elevated temperature and humidity and consequently products to be stored under such conditions may require a higher level of DETPA than those to be stored under milder conditions.
• Useful levels of DETPA range from 0.01% to 2% on the final composition. The levels usually found to be successful are 0.ll% by weight of the composition.
• DETPA has the advantage of compatibility with detergent compositions and does not affect the physical properties or the washing performance of the detergent composition to which it is added.
• the synthetic detergent if present, is conveniently an anionic compound, for example an alkyl aryl sulphonate, especially sodium dodecyl benzene su lphonate, an alkyl sulphate, or an alkyl glyceryl ether sulphonate. This is present in amount varying from 5 to 50% by weight of the composition. With the higher amounts of synthetic detergent, less additive may be found necessary for adequate stabilisation to storage.
• an alkyl aryl sulphonate especially sodium dodecyl benzene su lphonate, an alkyl sulphate, or an alkyl glyceryl ether sulphonate.
• a nonionic detergent may be used for example, an alkylene oxide condensate of an alcohol or phenol, such as tallow alcohol/9 ethylene oxide or nonyl phenol/9 ethylene oxide condensates.
• suitable soaps are the sodium, potassium or ammonium salts of tallow fatty acids or coconut fatty acids or the blends customary in the production of particulate soap-based products.
• the invention is also concerned with compositions in which both synthetic detergent and soap are present.
• detergent compositions may be present, viz. builders, perfume, etc.
• fluorescer components may be added, e.g. the cotton fluorescers of the triazinyl stilbene type.
• Example 1 Detergent products were prepared from a slurry of 200 g. active detergent (sodium dodecyl benzene sulphonate), 350 g. of sodium t-ripolyphosphate, 270 g. of builder salt and 400 g. of water. To this slurry was added fluorescer, and DETPA in the amounts shown in the following table. The resultant slurry was then drum dried and a portion of each power except the control portion was dry mixed with 10% sodium perborate. The powders were stored in laminated cardboard containers in a room held at 20 C. and relative humidity.
• DETPA sodium perborate 0. 0.08% B, 0.08% B, 10% sodium perborate, 0.5% DETPA
• Example 13 Sodium dodecyl benzene sulphonate A typical liquid formulation is: Anhydrous soap 4 Percent Sodium tripolyphosphate 25 Sodium dodecyl benzene sulphonate 10.0 Sodium sulphate 10 Potassium pyrophosphate 20.0 Sodium silicate 8 Sodium xylene sulphonate 4.0 Sodium perborate 15 Fluorescer A 0.03 Fluorescer B 0.08 DETPA 0.20 DETPA 0.2 Hydrogen peroxide 4.0
• a detergent composition consisting essentially of (1) a water-soluble organic detergent compound selected from the group consisting of (a) from about 5% to about 50% by weight of (a a nonionic detergent and (a an anionic non-soap detergent and (b) from about 5% to about 75% by weight of a soap, (2) from about 1% to about 50% by weight of a water-soluble inorganic oxygenreleasing per compound, (3) from about 0.01% to about 0.5% by weight of a fluorescer which is a derivative of l,3-diphenyl-A -pyrazoline selected from the group consisting of l-(p-sulphonamidophenyl)-3-(p-chlorophenyl)- A -pyrazoline, l-(p-carboxymethyl phenyl)-3-(p-chloropheny1)-A -pyrazoline and l-(m-chlorophenyl)v3-(p-acetylaminophenyl)-A -pyrazoline
• the detergent composition as defined by claim 1 wherein the water-soluble organic detergent compound is selected from the group consisting of nonionic deter- 5.
