Definitions

  • This invention relates to alkaline peroxide liquid detergent compositions for fabric washing.
  • Borax and sesquicarbonate are frequently incorporated into liquid detergent formulations. Both help to maintain a high wash liquor pH. We have found that each of these materials is incompatible with hydrogen peroxide. Sesquicarbonate gives the required buffering but it also gives rise to rapid decomposition of peroxide. Borax gives lower, but still unacceptably high, levels of peroxide decomposition.
  • WO 93/13012 discloses general purpose alkaline bleaching or disinfecting compositions comprising less than 1% of optional amine oxide surfactant, 0.5% borax, and 5 or 10% hydrogen peroxide.
  • the pH of the formulations tested is adjusted with sodium hydroxide to the relatively low initial value of 8.5 and the 12 week stability data for the 5% hydrogen peroxide formulation without any surfactant stored at about 30°C shows low loss of peroxide, but it is clear that the buffering is not adequate because the pH drops. There is no suggestion to use anything other than disodium tetraborate decahydrate (borax) as the buffer.
  • WO 93/01270 discloses an alkaline aqueous liquid washing agent comprising surfactant, hydrogen peroxide and a water soluble borate chosen from borax and sodium borate, the mole ratio of peroxide : borate being greater than 1.5: 1 and the composition having an initial pH of less than 8 in all the examples.
  • the invention resides in the ability of the water soluble borate and other ingredients to give a pH rise to about 9 when the composition is diluted. All formulations contain solvents such as ethanol and propylene glycol. Sodium perborate is not used or suggested.
  • an alkali metal perborate or percarbonate salt as a buffering additive in the manufacture of an alkaline peroxide- containing liquid detergent composition, characterised in that the level of the persalt added, based on peroxide equivalent content, is less than 90%, preferably less than 75% and most preferably less than half of the total peroxide equivalent in the composition.
  • the buffering additive is dissolved in the Uquid detergent composition as this avoids the problem of suspending a solid component. This is especially advantageous if the composition is isotropic.
  • buffering additive is perborate, preferably sodium perborate tetrahydrate or monohydrate.
  • an alkaline peroxide liquid detergent composition comprising surfactant, a peroxygen bleach and a soluble buffer, characterised in that the peroxygen bleach is hydrogen peroxide and the buffer is an inorganic persalt selected from alkali metal or alkaline earth salts of perborate and percarbonate, wherein the available oxygen from the hydrogen peroxide exceeds that from the persalt, preferably by at least 2: 1 and most preferably by at least 3: 1.
  • compositions of the present invention comprise 5-60% by weight surfactants.
  • Peroxide reacts with many surfactants to give reaction products which cause a lowering of the composition pEL
  • a wide range of surfactants which may be selected from anionic, cationic, nonionic, zwhterionic and amphoteric surfactants and blends thereof, may be used.
  • they may be chosen from any of the classes, sub-classes and specific materials described in "Surface Active Agents" VoL I, by Schwartz & Perry, Interscience 1949 and "Surface Active Agents” Vol.
  • Suitable nonionic surfactants include, in particular, the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.
  • Specific nonionic detergent compounds are alkyl primary or secondary linear or branched alcohols with ethylene oxide, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and emylenediamine.
  • Other so-called nonionic detergent compounds include long chain tertiary amine oxides, long chain tertiary phosphine oxides and dialkyl sulphoxides.
  • salting out resistant active materials such as described in EP 328 177, especially the use of alkyl poly glycoside surfactants, such as disclosed in EP 70 074.
  • Suitable anionic surfactants are usually water-soluble alkali metal salts of organic sulphates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term alkyl being used to include the alkyl portion of higher acyl radicals.
  • suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher (C 8 - 18 ) alcohols produced for example from tallow or coconut oil sodium and potassium alkyl (C 9 - 20 ) benzene sulphonates, particularly sodium linear secondary alkyl (C 10 - 15 ) benzene sulphonates; sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived from tallow or coconut oil and synthetic alcohols derived from petroleum; sodium coconut oil fatty monoglyceride sulphates and sulphonates; sodium and potassium salts of sulphuric acid esters of higher (C 8 - tg ) fatty alcohol-alkylene oxide, particularly ethylene oxide, reaction products; the reaction products of fatty acids such as coconut fatty acids esterified with isethionic acid and neutralised with sodium hydroxide; sodium and potassium salts of fatty acids amides of methyl taurine;
  • an alkali metal soap of a fatty acid especially a soap of an acid having from 12 to 18 carbon atoms, for example oleic acid, ricinoieic acid, and fatty acids derived from castor oil, alkylsuccinic acid, rapeseed oil, groundnut oil coconut oil, palmkernel oil or mixtures thereof.
  • the sodium or potassium soaps of these acids can be used.
  • the total detergent active material may be present at from 0.5% to 60% by weight of the total composition, for example from 1% to 40% and typically from 2% to 20% by weight. However, one preferred class of compositions comprises from 3-12% of detergent active material based on the weight of the total composition.
  • the actual amount of surfactant used will depend on the application, a hard surface cleaner will have a low amount, a fabric pre- treatment composition a rather higher amount and a concentrated detergent a high amount.

They were compared against a control without buffer and comparative example A which contamed 2% sesquicarbonate. Table 1 shows the results. Sodium percarbonate does not give such effective peroxide retention as the sodium perborate. Nevertheless the percarbonate buffering system could be used either alone or in admixture with perborate for detergents with short shelf-life requirements. The sesquicarbonate gave good buffering but the peroxide loss is unacceptable. Further experiments showed that borax gave buffering which was margmaUy worse than Examples 1 and 2, but the peroxide loss was much worse.
  • Chlorine is added to mains water for disinfection. Sometimes the level of chlorine is so high that it can lead to fabric dye damage when clothes are repeatedly washed in it.

  • Peroxide also provides enhanced bleaching in solution to give reduced damage from dye transfer during the wash.
  • Such a "colour safe" formulation requires the use of a buffer for pH stability on storage if it is to deliver satisfactory removal of fatty soil in the wash.

  • the initial pH of the Uquids was adjusted to 10 using 50%w/w sodium hydroxide (containing 0.5%w/w Dequest 2066).
  • Peroxide was added either as 60% w/w H 2 O 2 solution alone (in the controls) or with 0.5% w/w sodium perborate tetrahydrate as a buffer, to give 1% w/w total hydrogen peroxide equivalents in the controls and the examples.
  • the order of addition of the components was perborate, then peroxide solution, then sodium hydroxide.

  • Example 4 0.85% H j O 2 + 0.5%w/w sodium perborate buffer
  • Examples 3 A and 3B were prepared as identical dupUcates to check the reproducibiUty of the buffered system. Reproducible stabiUty is a key requirement for a commercial system Many of the prior art systems are capable of giving good stabiUty on a one off basis but the effect is not reproducible.
  • Buffering is significantly improved in dupUcate examples 3A and 3B containing 0.5% w/w sodium perborate tetrahydrate in solution as a buffer.
  • AU examples show similar peroxide stability after 4 weeks storage at 37°C. It is known that peroxide is inherently more stable when the pH is lower. The stabiUty of the two examples containing sodium perborate tetrahydrate is reproducible especiaUy for longer test periods. The beneficial effect of using the soluble persalt as a buffer is obtained for both sequestrant systems.
