Definitions

  • the present invention relates to a kit or cleansing system comprising a personal cleansing hand held bath sponge;, and a liquid cleanser for bath or shower, comprising a halogenated biocide or bacteriostat.

  • U.S. Patent No. 5,295,280 to Hudson et al . teach a washing device for scrubbing the body.
  • the washing member i.e., sponge
  • the washing member has a substantial uniform cross-section and a substantially porous inner structure which is said to allow water and soap to permeate the surface and interior thereof (column 2, lines 28-31)
  • U.S. Patent No. 5,144,744 to Campagnoli also teaches sponges (specifically diamond-mesh polyethylene sponge) clearly designed for bath usage (see claim 1) .
  • WO 95/00116 (assigned to Procter & Gamble) relates to a personal cleansing system comprising a diamond-mesh bath sponge used in combination with a liquid cleanser comprising a moisturizer.
  • the diamond-mesh sponge is said to enhance lather profile of a cleanser containing such moisturizer.

  • the invention comprises a method for enhancing deposition of halogenated bacteriostat in a liquid composition comprising an effective amount of surfactant which method comprises applying said bacteriostat containing cleanser to the sponge and/or desired surface (i.e., body) and applying the sponge (with or without bacteriostat depending on whether cleanser was added to sponge or to body) to the desired surface. That is, the cleanser can be applied to the sponge and then applied to the body with the sponge; or the cleanser can be applied to the body and then rubbed on the body with the sponge.
  • Figure 1 is a perspective representation of a diamond-mesh polymeric sponge.
  • Figure 2 is a picture showing how the sponge can be held in the hand
  • Figure 3 shows netting mesh which can be used to make the sponge.
  • the present invention is directed to the discovery that when certain bacteriostat containing liquid cleansers are applied to the body/skin using a light weight polymeric meshed hand held sponge, there is greater deposition/delivery of these bacteriostats than if they had been delivered by a regular sponge. That is, the sponge synergistically interacts with the liquid cleanser plus bacteriostat to enhance delivery of the bacteriostat.
  • the liquid cleanser containing bacteriostat and the mesh sponge are packaged together as a kit.
  • the liquid cleanser is usually in a separate container in an amount large enough for several uses with the sponge. More specifically, the personal bath or shower body cleansing system comprises:
  • a bacteriostat preferably a halogenated bacteriostat, more preferably selected from the group of halogenated bacteriostats described below.
  • the combination of polymeric mesh sponge and cleanser plus bacteriostat enhance the deposition of the bacteriostat. That is the sponge interacts with the bacteriostat to enhance delivery/deposition in a manner superior to other types of sponges.
  • the cleansing polymeric mesh sponge can be prepared from readily available raw materials or with specially designed mesh materials.
  • the polymeric mesh sponge is preferably prepared from extruded tubular netting mesh which has been prepared from special strong and flexible polymeric material.
