Definitions

  • the invention relates to pourable bleaching compositions comprising a solid, substantially water-insoluble organic peroxy acid stably suspended in an aqueous medium.
  • the present invention relates to bleaching compositions of the above type characterized in that the aqueous medium also comprises at least two polymers wherein the first polymer is one or more natural gums, preferably xanthan gum, and the second polymer is selected from the group consisting of polyvinyl alcohol, cellulose derivatives and mixtures thereof.
  • the bleaching composition may additionally be comprised of an electrolyte, such as Na2SO4.
  • the bleaching compositions of the current invention may be used alone or in combination with other bleaches. Additionally, the current bleaching compositions may be included as part of detergent, bleaching, cleaning and/or disinfecting formulations.
  • Bleaching compositions comprising a solid, substantially water-­insoluble organic peroxy acid stably suspended in an aqueous medium are generally known from British Patent Specification 1 535 804. It claims fabric bleaching compositions having a viscosity from 200 to 100,000 cp. and a non-alkaline pH, the compositions comprising an aqueous carrier, 1-40 weight % particulate organic substantially water-insoluble peroxygen compound and a thickening agent.
  • thickening agents are inorganic thickeners, such as clays, and organic thickeners, such as water-soluble gums, mucilaginous materials, starches, polyacrylamides and carboxylpolymethylene.
  • British Patent Specification 1 535 804 discloses the use of cellulose derivatives such as carboxymethyl celluloses, hydroxypropyl cellulose and methyl hydroxybutyl cellulose, hydrolyzed proteins such as hydrolyzed keratins, glutens, polyvinyl alcohol and polyvinylpyrrolidone, and natural gums such as gum arabic, carrageen and various agars.
  • cellulose derivatives such as carboxymethyl celluloses, hydroxypropyl cellulose and methyl hydroxybutyl cellulose
  • hydrolyzed proteins such as hydrolyzed keratins, glutens, polyvinyl alcohol and polyvinylpyrrolidone
  • natural gums such as gum arabic, carrageen and various agars.
  • non-prepublished European Patent Application No. 283 792 discloses storage-stable, pourable aqueous bleach suspensions having a pH value in the range of 1 to 6 and containing (a) particulate, water-­insoluble peroxy-carboxylic acid (e.g., diperoxydodecanedioic acid), (b) xanthan gum or agars, (c) hydratable neutral salt (e.g., Na2SO4), (d) optionally an acid for pH regulation (e.g., H2S04), and (e) aqueous liquid.
  • a particulate, water-­insoluble peroxy-carboxylic acid e.g., diperoxydodecanedioic acid
  • xanthan gum or agars e.g., xanthan gum or agars
  • hydratable neutral salt e.g., Na2SO4
  • optionally an acid for pH regulation e.g., H2S04
  • liquid bleaching compositions rather than solid bleaching compositions in automatic clothes washers and dryers.
  • liquid bleaching compositions there is no need for cost-increasing shaping steps, such as granulating and drying.
  • liquid bleaching compositions are more easily dispersed in wash liquor or in an automatic clothes dryer so the fabrics are more rapidly and evenly bleached. Uneven bleaching can damage fabric as a result of localized high concentrations of bleaching agent.
  • the bleaching compositions of GB 1 535 804 at least as far as they are pourable, have the disadvantage that they are not physically stable.
  • Composition 7 in EP 176 124 after prolonged storage, pourable bleaching compositions of GB 1 535 804 undergo phase separation, producing a thick bottom layer which is difficult to disperse or homogenize. Consequently, the aforementioned advantage of even fabric distribution may be partly eliminated.
  • GB 1 535 804 does not disclose or suggest the use of more than one thickening agent in a single fabric bleaching composition. Indeed, it is clear from Example III of GB 1 535 804 that the cellulose derivatives tested as thickening agents were tested in individual, separate bleach compositions. Additionally, the bleach composition of Example III of GB 1 535 804 is a "thick, semi-gelatinous composition" (see page 11, lines 32-35 of GB 1 535 804) rather than a pourable composition of the present invention.
  • United States Patent 4 232 141 discloses, inter alia, grinding coarser particles of a polymerization initiator in an aqueous medium containing a dispersing agent to form an aqueous dispersion of the polymerization initiator.
  • the polymerization initiator may be, inter alia , a peroxy dicarbonate or a benzoyl peroxide.
  • Some vinyl chloride polymerization suspensions of the examples of US 4 232 141 contain a mixture of polyvinyl alcohol and methyl cellulose. Mowever, as demonstrated herein below, an aqueous suspension acceptable under bleaching conditions (pourability, physical stability and chemical stability) and prepared as suggested by US 4 232 141 is not physically stable.
  • the bleaching compositions of the current application are physically stable when the compositions undergo insignificant, and preferably no, phase separation during a reasonable storage time.
  • the solid, substantially water-insoluble organic peroxy acids which may be used in the bleaching compositions of the current invention are generally known in the art.
  • the solid organic peroxy acids disclosed in European Patent Applications 160 342, 176 124 and 267 175, US Patents 4 681 592 and 4 634 551 and GB Patent Specification 1 535 804 may be used and are all herein incorporated by reference.
  • organic peroxy acids which may be used in the compositions of the current invention are (1) diperoxy acids, such as 1,12-diperoxydodecanedioic acid (“DPDA”), diperazelaic acid and 1,13 diperoxytridecanedioic acid, (2) peroxy acids which have a polar amide link in the hydrocarbon chain, such as N-decanoyl-6-amino-peroxyhexanoic acid, N-dodecanoyl-6-aminoperoxyhexanoic acid, 4-nonylamino-4-oxoperoxybutyric acid and 6-nonylamino-6-oxoperoxyhexanoic acid, and (3) alkyl sulphonyl peroxycarboxylic acids, such as heptyl sulphonyl perpropionic acid, octyl sulphonyl perpropionic acid, nonyl sulphonyl perpropionic acid and decyl sul
  • the solid organic peroxy acid may be coated with a water-impermeable material, such as the fatty acids lauric acid, myristric acid and mixtures thereof, as known from European Patent Application 254 331.
  • the amount of organic peroxy acid in the current bleaching formulations depends on criteria such as the active oxygen (“A.O.") content of the peroxy acid and the intended use of the bleaching composition.
  • the preferred amount of peroxy acid is that which will provide effective washing, bleaching, cleaning and/or disinfecting in a diluted use liquor.
  • the current bleaching compositions have a peroxy acid concentration which will provide an A.O. content of between about 1 and about 200 ppm, and preferably between about 2 and about 100 ppm in a typical diluted liquor for use in washing, bleaching, cleaning and/or disinfecting.
  • the first polymer is one or more natural gums.
  • the natural gums may be xanthan gum, guar gum, gum arabic, carrageen and agars obtained from seaweed. Xanthan gum is the preferred natural gum.
  • the amount of natural gum desired in the current bleaching formulations is the amount which is effective to provide a physically and chemically stable, pourable aqueous formulation. Generally, though non-limiting, natural gum is present as about 0.1 to about 1 wt.% of the bleaching composition.
  • the second polymer is selected from the group consisting of polyvinyl alcohol, one or more cellulose derivatives and mixtures thereof.
  • a group of cellulose derivatives particularly useful are cellulose ethers.
  • Cellulose ethers are known from, for example, Ullmann's Encyclopedia of Industrial Chemistry , Fifth Edition, Vol. A5, pages 461-487.
  • Of particular use in the current bleaching compositions are methyl cellulose, methyl hydroxypropyl cellulose, methyl hydroxybutyl cellulose, hydroxyethyl cellulose and carboxymethyl cellulose.
  • the amount of second polymer incorporated in the current bleaching formulations is the amount which will provide a physically and chemically stable, pourable aqueous bleaching composition. Generally, though non-limiting, the second polymer is present as about 0.02 to about 2 wt.% of the bleaching composition.
  • An electrolyte may also be present in the aqueous medium to help provide a useful, pourable bleaching composition.
  • the electrolyte may result from the residual acid present in the peroxy acid as a result of the peroxidation reaction.
  • the electrolyte may also be added deliberately to enhance the physical stability of the current suspensions and increase their safe handling (See European Patent Application 176 124).
  • suitable electrolytes are Na2SO4, K2SO4, MgSO4, Al2(SO4)3, NaNO3 and borate salts.
  • the amount of electrolyte present depends, inter alia , on the peroxy acid and the polymers employed and on the intended use of the suspension. However, in general, though non-limiting, the electrolyte may be up to about 30 wt.% of the composition.
  • the current bleaching compositions may also comprise antifreezing agents, such as glycol.
  • the bleaching compositions of the current invention are further illustrated by the following non-limiting examples.
  • test suspensions 500 grams were prepared by mixing 274 grams organic peroxy acid (1,12-diperoxydodecandioic acid (“DPDA”) in wet filter cake form, having an active oxygen (A.O.) content of 5.47%) with a solution of 15 grams Na2SO4 and 1 gram test polymer (if present) based on active material in 210 grams water. This produced test suspensions having an active oxygen content of 3.0%.
  • the viscosity of each test suspension was measured (Brookfield RV, 20 r.p.m.) and the physical stability (in terms of phase separation) was monitored during an 8 week 20°C storage period.
  • Table 1 Test Suspension Water-soluble Polymer Viscosity (mPa.s) Phase Separation 1A None 2400 None 1B Xanthan gum (Rhodigel 23 from Rhone Poulenc) 1700 Small amount 1C Hydroxyethyl cellulose (Natrosol 250 L from Hercules) 50 Large amount
  • Test Suspension 1B is not physically stable as indicated by the phase separation.
  • the suspensions of the current invention must be chemically stable as well as pourable and physically stable. That is, the bleaching compositions of the current invention must retain their ability to bleach while they are being stored prior to use.
  • the chemical stability of a peroxy acid is indicated by the retention of active oxygen (A.O.). Mowever, active oxygen is affected by the presence of H2O2 as well as peroxy acid (such as DPDA). H2O2 is formed by the decay reactions of peroxy acids. Therefore, a more accurate indication of chemical stability after storage is the "residual peroxy acid", or in this case, "residual DPDA”.
  • Residual DPDA is the active oxygen content (A.O.) minus H2O2 formed by the decay of the peroxyacid.
  • the H2O2 content was determined by extraction with a mixture of diethyl ether and water, separation of the water layer, addition of Ti(IV) reagent and spectrophotometric measurement of the yellow complex formed.
  • the first suspension was completed by adding 15 grams Na2SO4 and 0.25 gram Dequest 2010 (a sequestering agent available from Monsanto).
  • the second suspension was completed by adding 15 grams Na2SO4, 0.25 grams Dequest 2010, 1 gram hydroxyethyl cellulose (Natrosol 250 L) and 1 gram xanthan gum (Rhodigel 23).
  • the initial active oxygen content and viscosity of each suspension were measured.
  • Each suspension was divided in half. One half of each suspension was stored for 8 weeks at 20°C and the other half stored for 8 weeks at 30°C.
  • suspensions of the current invention were conveniently pourable as well as being chemically and physically stable over the 8 week test period.
  • a bleaching composition comprised of components suggested by the disclosure in US Patent 4 232 141 was prepared as a comparative example.
  • a bleaching composition was prepared in accordance with the composition of Example 3 modified by the addition of 1.0 gram xanthan gum, placing the test suspension of this Example 4 within the scope of the current invention.
  • the viscosity of the test suspension was 938 mPa.s (Brookfield LTV, 30 r.p.m.). After 8 weeks storage at 20°C, only an insignificant 4 ml of water separated from the test suspension.
  • the composition was conveniently pourable.
  • organic peroxy acids may be prepared in such a manner that the resulting organic peroxy acid also comprises a water-impermeable material, such as fatty acid.
  • the fatty acid may, among other things, increase the safe handling and use of organic peroxy acids.
  • the lauric acid-coated DPDA was prepared substantially in accordance with the method of European Patent Application 254 331 by heating and stirring a suspension of DPDA at 50°C, adding lauric acid in a weight ratio of 3:1 DPDA to lauric acid, stirring for 10 minutes, cooling and separating the DPDA and lauric acid combination from water on a filter.
  • Test Suspension 3A does not contain a water-soluble polymer. It does not separate over the 8 week period but it is not conveniently pourable.
  • Test Suspensions 3B, 3C and 3D contain the water-soluble polymer PVA (as suggested by US Patent 4 232 141). They are conveniently pourable but have unacceptable phase separation.
  • Test Suspension 3E containing both xanthan gum and PVA according to the present invention, shows no phase separation, is as chemically stable as Test Suspension 3A and is conveniently pourable.
  • the current bleaching compositions are suitable for use with organic peroxy acids which also comprise a water-impermeable material.
  • the bleaching compositions of the current invention are capable of containing substantially increased amount of organic peroxy acid on a weight percent basis.
  • aqueous suspensions of the organic peroxy acid DPDA are capable of a maximum of about 32 wt.% DPDA and have an active oxygen content of about 3.5%.
  • the active oxygen content may be reduced to about 2.5%.
  • aqueous suspensions have been prepared using the polymer system of the current invention to produce bleaching compositions with substantially increased DPDA (with and without lauric acid) concentration and substantially increased active oxygen content. The details of these compositions are contained in Table 4.
  • Suspensions having relatively high peroxy acid concentrations are preferred for industrial purposes, such as bulk transportation and handling.
  • relatively low peroxy acid concentrations e.g., about 5-10 wt.% for peroxyacids such as DPDA for U.S. consumers
  • the previously described pourable, storage-stable concentrated suspensions can be diluted to form pourable, storage-stable dilute suspensions.
  • Suspension 5A is a comparative example containing peroxy acid and sodium sulfate.
  • Suspension 5B is a two polymer formulation within the current invention. Comparative Suspension 5A was used to prepare 500 ml dilute Comparative Suspension 5C. Suspension 5B was used to prepare 500 ml dilute Suspension 5D according to the current invention. As reported in Table 5, dilute Suspension 5D is physically and chemically stable over a 4 week period while Suspension 5C separates after 3 weeks at 40°C. Chemical stability is reported in terms of "Residual DPDA".
  • This Example 8 demonstrates, inter alia , the effect of temperature on suspensions of the current invention. Temperature effects are particularly important in that industrial processing and transportation is likely to occur at lower temperatures (e.g., about 10°C-30°C) while consumer storage and usage is likely to occur at higher temperatures (e.g., about 20°-40°C).
  • Suspension 8A is identical to Suspension 2A.
  • Suspension 8B is identical to Suspension 2B.
  • Portions of the suspensions were stored for 8 weeks at 20°C, 30°C and 40°C then tested for chemical stability (residual DPDA), phase stability and rheological stability ("pourability"). Additionally, these characteristics were also monitored after 4 weeks for suspensions stored at 40°C. The results are provided in Table 6. It should be noted that “pourability” was determined by pouring (or attempting to pour) each suspension from a 500 ml container. Suspensions giving a streaming behavior similar to that of commercially available heavy duty detergents were "pourable".
  • suspensions of the current invention are chemically, physically and rheologically stable over time and temperature. Additionally, the chemical stability and physical stability of the suspension of the current invention (Suspension 8B) are equal, or substantially equal, to those of Suspension 8A while Suspension 8B has the advantage of rheological superiority and stability.
