Definitions

  • the present invention is concerned with improvements relating to fabric cleaning and in particular, with an improved foam control using a concentrated detergent.
  • WO2009/153184 (Unilever) describes a method of laundering fabrics that uses very low levels of in- wash surfactant, preferably comprising anionic surfactant. Wash performance is boosted by inclusion of high levels of specific polymers and enzymes. The skilled person would expect that compositions delivering such low in-wash levels of anionic surfactant would be more affected by the carry over of cationic on the fabric from previous washes/rinses than compositions and laundry processes which deliver higher levels of in-wash anionic surfactant.
  • a first aspect of the present invention provides a method of reducing the number of rinse steps in a fabric washing process which comprises the steps of:
  • nonionic and/or anionic and/or zwitterionic surfactant which 10-40% wt of surfactant preferably passes the Calcium Tolerance Test described herein, and in addition, from 0.1 to 2% wt., fatty acid,
  • the wash liquor contains less than 10%, more preferably less than 5% and most preferably less than 2% of the foam present before any rinse step.
  • the liquid detergent composition described in this invention has a pH of from 7.0 to 8.0.
  • the fabric washing process of the current invention is carried out at from 10 to 40 degrees Celsius.
  • pourable means that it can be poured.
  • it has a shear viscosity (at 25 Celsius) of below preferably below 2 Pa.s at a shear rate of 21 s "1 .
  • Preferred viscosities are in the range 1.0 - 0.1 Pa.s.
  • the composition may be shear thinning.
  • the dose is less than 35 ml, more preferably less than 30 ml, and most preferably less than 25 ml per wash, even being 20 ml or less per wash.
  • the wash liquor obtained comprises 0.25 to 0.55 g l of non-soap surfactant, for example 0.4 g L or lower.
  • Doses may be measured by hand, more preferably metered by a suitable device or provided as pre-measured unit doses. The use of a container with metering means to deliver a dose with a dose to dose variability of less than 20 %wt and preferably less than 10 %wt is preferred.
  • the Calcium Tolerance Test used herein is that defined in EP1771543.
  • a surfactant blend is prepared at a concentration of 0.7 g l in water containing sufficient calcium ions to give a French Hardness of 40 degrees.
  • Other electrolytes such as sodium chloride, sodium sulphate, sodium hydroxide are added as necessary to adjust the ionic strength to 0.5M and the pH to 10.
  • the absorption of light of wavelength 540 nm through 4 mm of sample is measured 15 minutes after sample preparation. Ten measurements are made and an average value is calculated. Samples that give an absorption value of less than 0.08 are deemed to be calcium tolerant.
  • the dilution factor in the method of the first aspect of the present invention is by a factor of at least 500, by which is meant that one volume of composition is mixed with at least 500 volumes of water.
  • the dilution factor is preferably less than 2500.
  • Particularly preferred dilution factors fall in the range of 500 to 1500, most preferably 500 to 1000.
  • the detergent composition comprises not more than 25 %wt, even more preferably not more than 20 %wt, of non-soap surfactant.

  • the method of the invention is conducted in a washing machine, more preferably in a non-vertical axis machine, most preferably in a horizontal-axis machine with a drawer dispensing system.
  • compositions in the method according to the invention may be further improved by the presence of one or more of enzymes, polymers and shading dyes. It is particularly preferable that at least one enzyme is present in the compositions of the invention. Lipase is a particularly preferred enzyme.

This means that the amount in the composition is higher than typically found in liquid detergents. This can be seen by the ratio of non-soap surfactant to lipase enzyme in particular.
  • a particularly preferred lipase enzyme is available under the trademark LipocleanTM from Novozymes.
  • a range of possible polymers may be employed to improve the performance of the compositions used in the method of the present invention. Again, the efficacy of these polymers is much improved by the reduction in the level of surfactant present in the wash.

Dans le procédé, la composition est diluée d'un facteur supérieur à 500 pour obtenir une liqueur de lavage qui comprend de 0,8 à 0,05 g/l de tensioactif, et la liqueur de lavage est mise en contact avec des tissus. La composition peut en outre comprendre un ou plusieurs éléments parmi une lipase, une polyéthylèneimine, un colorant bleu violet présentant de préférence un pic d'adsorption optique dans la plage de 540 à 600 nm, un agent fluorescent, un polymère d'inhibition de transfert de colorant, un agent polycarboxylate anti-redéposition, un polymère facilitant le lavage et un parfum (de préférence encapsulé), et de préférence des combinaisons ceux-ci.
