Definitions

  • the present invention relates to detergent compositions based on hypochlorite.
  • the present invention relates to the use of hypochlorite comprising compositions.
  • hypochlorite-comprising compositions have a strong odour related to them. This odour is due to the presence of bleach in the composition. The consumer considers this a highly undesirable feature of such compositions.
  • the alodour is noticeable in all compositions comprising hypochlorite. Indeed, even when only small concentrations of hypochlorite are present in a composition the odour is noticeable.
  • compositions themselves have an undesirable odour all articles and surfaces treated with a hypochlorite-comprising composition suffer from malodour as well.
  • hypochlorite-comprising composition the consumer's person may also be subject to a residual bleach odour, particularly on the hands. This odour may remain for a number of hours, in spite of washing.
  • the odour is also very persistent and the odour tends to linger at and around the point of application. Often the odour can still be detected a number of hours after the composition has been used. The pungent odour is considered unpleasant by the consumer and indeed in some cases even nauseous.

A dry sponge is placed in the container and left until all the solution has been soaked up. A tile is then wiped lightly five times with the sponge. The tile is then placed in another glass container with the lids slightly ajar. The tile is then smelt without removing it from the glass container at intervals of 0, 15, 30, 45, 90 and 120 minutes. A rating for the odour is then given using the above scale. The test is then repeated.
  • the hypochlorite comprising composition is diluted, 1 part to 25 parts water. Sufficient solution is made to fill a container to a level to submerge the hands and wrists of the tester. The tester places one hand into each of the solutions to be tested for 30 seconds. The hands are then removed from the solution and placed under cold running water for 5 seconds. Each hand is patted dry with paper towels. The hands are ' then smelt at time intervals of 0, 15, 30, 45, 60, 90 and 120 minutes. A rating for odour is then given using the above scale. After 3 hours the hands are rewetted and smelt. The test is then repeated.
  • 5grms of the hypochlorite-comprising composition is placed on a damp sponge.
