Definitions

  • Modern detergents therefore consist of a combination of detergents as wash-active Substances, bleaching agents and additives that increase washing power, the so-called builders, which on the one hand remove the hardness of the wash liquor and on the other hand deposits of inorganic Prevent salting on the laundry and thereby for a "soft grip" of the laundry care after washing.
  • Polymeric phosphates in particular sodium tripolyphosphate, are considered to be excellent builders. Because of the risk of eutrophication of the rivers and lakes by the phosphate content in the domestic Sewage has been suggested to use zeolites as a builder.
  • EP-A-0 263 520 describes a detergent which, in addition to the usual constituents, contains 0 to 5% by weight of a quaternary ammonium compound and 1 to 30% by weight of a plasticizer system, consisting of 10 to 90% by weight of an alkylamine and 90 to 10% by weight of a crystalline sheet silicate of the formula Me 2 Si x O 2x + 1 .yH 2 O, in which Me contains an alkali metal or H, x is a number less than 7 and y is a number less than 7x.
  • EP-A-0 028 432 describes a detergent composition which contains, inter alia, sodium tripolyphosphate, insoluble silicates, TAED, alkylbenzyl sulfonates, ethoxylated C 15 alcohols, sodium perborate tetrahydrate, brighteners and sodium sulfate.
  • EP-A-0 634 484 describes packaged granular detergent compositions where the packaging has certain water vapor permeability values.
  • the invention is therefore based on the object of providing a detergent which is improved Has storage stability and an increased bleaching effect as well as the "soft" in the laundry Grip 'maintained.
  • a detergent of the type mentioned at the outset characterized in that that the bleach is sodium percarbonate and the amount of Bleaching agent is such that 0.5 to 4% by weight, in particular 1.0 to 2.5% by weight, is more active in washing There is oxygen in the detergent.
  • the crystalline sheet silicates used in the preparation of the detergent according to the invention can be prepared according to DE-34 13 571 A1. Although all of the crystalline sheet silicates listed in DE-34 13 571 A1 can be used in the detergent according to the invention, it has been shown that ⁇ -Na 2 Si 2 O 5 should be given preference if there is an increased bleaching effect in the Washing process arrives.
  • the determination of the wash-active oxygen (AVOX) of the bleach and the detergent was carried out according to Dr. E. Heinerth, Tenside 2 (1965) 180.
  • the sodium perborate tetrahydrate (NaBO 3 .4H 2 O) investigated had an AVOX number of 10% by weight; the sodium perborate monohydrate (NaBO 3 .H 2 O) had an AVOX number of 15% by weight; the sodium percarbonate (2 Na 2 CO 3 .3H 2 O 2 ) had an AVOX number of 13.5% by weight.
  • the washing power (bleaching effect) of the detergent was determined as Whiteness of the test fabrics (WFK polyester / cotton with tea staining, Order code 20 G) determined according to DIN 44983.
  • the storage tests were carried out according to the following forced test conditions:
  • the detergent to be examined was stored in a climatic cabinet at a relative humidity of 70% at a temperature of 37 ° C.
  • the detergent was packed in a wax box.
  • the water vapor permeability of the packaging was 0.4 g / m 2 ⁇ h.
  • Table 1 shows the detergent formulations tested listed.
  • Table 2 shows the degradation values of the bleach in Depends on the time after the forced storage test conditions compiled.
  • 2 were commercially available Detergent based on zeolite and sodium tripolyphosphate included in Table 2.
  • the bleach breakdown, especially sodium percarbonate is present of zeolite very large.
  • the detergent formulations were in accordance with DIN 44983 2 and 4 tested and calculated according to equation I.
  • the washing power (bleaching effect) of the detergent 2 was 30.0%; that of the detergent according to the invention was 4 36.5%.
