Definitions

  • the present invention relates to a stabilization system for detergent enzymes. More particularly, it relates to a stabilization system for detergent enzymes in an aqueous liquid detergent composition having a pH of at least 8.5, which further contains a peroxygen bleach.
  • EP-A-293 040 discloses aqueous liquid detergent compositions containing a peroxygen bleach. The compositions are designed to limit the amount of available oxygen in solution. Enzyme-containing compositions are disclosed which alls comprise stabilization systems for the enzymes.
  • EP-A-28 865 discloses a stabilization system for enzymes in a liquid detergent composition comprising formic acid or a salt thereof and calcium ions.
  • the disclosed composition have a pH of from 6.5 to 8.5.
  • US-A-4,381,247 discloses a dry, powdered, enzyme containing, bleaching compositions; stabilizers including magnesium sulphate are disclosed.
  • Liquid detergent compositions containing enzymes and stabilization agents including magnesium salts are disclosed in US-A-3,676,374 and US-A-4,443,355
  • the present invention relates to aqueous liquid detergent compositions having a pH of at least 8.5, containing an organic surfactant, a peroxygen compound, a detergent enzyme, characterized in that it further contains, as an enzyme stabilizing system, from 10 ppm to 10 000 ppm of magnesium ions.
  • compositions also contain a certain amount of chelants.
  • Such compositions contain higher levels of magnesium ions, from 100 ppm to 10 000 ppm.
  • compositions according to the invention have a pH at room temperature of at least 8.5, more preferably at least 9.0, most preferably at least 9.5 .
  • the peroxygen compound preferably is a perborate, most preferably perborate tetrahydrate.
  • compositions contain a water-miscible organic solvent such as ethanol. This reduces the solubility of any dispersed peroxygen compound, resulting in a low level of available oxygen in the liquid phase that is controlled to be under 0.5 %, preferably below 0.1 %.
  • Suitable detergent enzymes include detergent proteases, detergent amylases, detergent lipases and detergent cellulases.
  • Preferred detergent compositions herein are those that contain a detergent protease, preferably a high alkaline protease, from 0.01 % to 5 % on 8 KNPU/g basis, most preferably from 0.05 % to 2.5 %
  • liquid detergent compositions do not fully match the performance profile of high quality granular detergent; this is a reason why liquid detergent compositions containing detergent enzymes have appeared over the past years.
  • compositions which further contain peroxygen bleaches which further contain peroxygen bleaches. It is still well known that peroxygen bleach containing compositions at higher pH, i.e. above 8.5, perform better in the wash.
  • compositions are very stressing to detergent enzymes and autolysis becomes more of a problem as the pH of the compositions increases. It has been found that calcium salts are no longer efficient in stabilizing the detergent enzyme in such pH conditions, they even inhibit the enzyme's performance upon storage.
  • magnesium ions provide an efficient stabilizing system for the enzyme, in bleach containing, high pH compositions when added in an amount ranging from 10 ppm to 10 000 ppm.
  • any magnesium source capable of supplying free (water soluble) magnesium ions can be used. Preferred, for reasons of availability, are magnesium sulfate, magnesium chloride, magnesium acetate and magnesium formate, most preferred are magnesium acetate and magnesium chloride. Such compounds can be added in the composition as such.
  • the magnesium source may be "premixed" with the enzyme, hereinafter described, before being introduced into the composition. Said premix may also be evaporated or lyophilised so as to obtain solid particles. Such particles may then be coated with e.g. silicone oil.

  • Perborate bleaches in the present composition can be in the form of small particles i.e. from 0,1 to 20 micrometers, said particles having been formed by in situ crystallization of the perborate.
  • in situ crystallization relates to processes whereby perborate particles are formed from larger particles or from solution, in the presence of the water/anionic surfactant/detergent builder matrix. This term therefore encompasses processes involving chemical reactions, as when sodium perborate is formed by reacting stoichiometric amounts of hydrogen peroxide and sodium metaborate or borax. It also encompasses processes involving dissolution and recrystallization, as in the dissolution of perborate monohydrate and subsequent formation of perborate tetrahydrate. Recrystallization may also take place by allowing perborate monohydrate to take up crystal water, whereby the monohydrate directly recrystallizes into the tetrahydrate, without dissolution step.

  • borate compounds including e.g., borax and boric acid can be used. If borax is used as the boron compound, a stoichiometric amount of a base, e.g. sodium hydroxide, is added to ensure reaction of the borax to metaborate. The process then proceeds as described hereinabove for metaborate conversion.
  • a base e.g. sodium hydroxide
  • hydrogen peroxide other peroxides may be used (e.g., sodium peroxide), as known in the art.
  • Preferred liquid detergent compositions contain, in addition to water, a water-miscible organic solvent.
