Definitions

  • Protease enzymes are used in laundry detergent formulations to remove protein containing stains from fabrics.
  • amyloliquefaciens Bacillus pumilus and Bacillus gibsonii described in US7262042 and WO09/021867 , and subtilisin lentus, subtilisin Novo, subtilisin Carlsberg, Bacillus licheniformis, subtilisin BPN', subtilisin 309, subtilisin 147 and subtilisin 168 described in WO89/06279 and protease PD138 described in WO 93/18140 .
  • Other useful proteases may be those described in WO92/175177 , WO01/016285 , WO02/026024 and WO02/016547 .
  • trypsin-like proteases are trypsin (e.g.
  • two or more anionic surfactant are present, preferably linear alkyl benzene sulphonate together with an alkyl ether sulphate.
  • precipitating builder materials examples include sodium orthophosphate and sodium carbonate.
  • the laundry detergent formulation is a non-phosphate built laundry detergent formulation, i.e., contains less than 1 wt% of phosphate.
  • the powder laundry detergent formulation is carbonate built.
  • the composition preferably comprises a fluorescent agent (optical brightener).
  • fluorescent agents are well known and many such fluorescent agents are available commercially. Usually, these fluorescent agents are supplied and used in the form of their alkali metal salts, for example, the sodium salts.
  • the total amount of the fluorescent agent or agents used in the composition is generally from 0.005 to 2 wt %, more preferably 0.01 to 0.1 wt %.
  • Preferred classes of fluorescer are: Di-styryl biphenyl compounds, e.g. Tinopal (Trade Mark) CBS-X, Di-amine stilbene disulphonic acid compounds, e.g. Tinopal DMS pure Xtra and Blankophor (Trade Mark) HRH, and Pyrazoline compounds, e.g.
  • the composition comprises a perfume.
  • the perfume is preferably in the range from 0.001 to 3 wt %, most preferably 0.1 to 1 wt %.
