Definitions

  • the invention relates to a personal cleansing system and a personal cleansing kit, and more specifically wherein an assembly of one or more of skin cleansing, aesthetic, and skin moisturization and benefit bars are selected, and then combined in a customized manner.
  • Toilet bar skin cleaning properties are well known. An ideal bar composition not only cleans, but provides a large quantity of lather and leaves the skin feeling comfortable. Consumers also desire to obtain toilet bars with good hardness, low mush, and that contain appealing fragrances and one or more skin benefit agents and emollients for moisturizing and treating the skin according to individual preferences and needs.
  • JP Patent No. 10137152 also teaches a solid soap in an expansible net.
  • the problem with prior art toilet bar and pouch implements is the lack of a system and a kit to make available a product with a wide range of sensory properties in a convenient format but with excellent physical properties.
  • a "bar” is herein defined as an individual toilet bar or other geometrically or amorphous shaped body that may be selected from and combined with other toilet bars or bodies in a porous holder according to the invention.
  • these separate bars may be presented in a kit and combined in a porous pouch to bring together all the cleansing and skin treatment attributes desired by the consumer and at the same time form a useful cleansing implement with superior lathering properties compared to a single toilet bar formed with the same ingredients. Furthermore it has been found that production efficiency is enhanced by making the bars separately, since such bars if made by the melt cast process have a shorter solidification time. Moreover, the variability of solidification time in melt cast bars may be minimized by separate manufacturing of the bars. With respect to extrusion of such bars, the variability of processing parameters such as extrusion rate and stampability may also be minimized by separate manufacture of the bars.
  • a personal cleansing kit according to claim 1.
  • the aesthetic ingredient is defined as either fragrances, colorants, pigments, cosmetics (without benefit ingredients as hereafter defined), suspended bodies and blends thereof; and the benefit ingredient is defined as either emollients, skin active materials (as defined below) and blends thereof.
  • the present invention consists of a kit comprising two or more solid/semi-solid bars that may be combined in a porous closable pouch by the user and the system for fabricating such a combination.
  • the kit's parts i.e. the cleansing, aesthetic and benefit bars and porous holder advantageously contained in an outer container may also be purchased separately by the consumer, who can use the inventive system to create a customized cleansing article by selecting two or more of the compositions and inserting them into the pouch prior to showering.
  • the bars may serve different functions such as cleansing, benefit delivery etc. They may also have different ingredients that combine together to provide a unique benefit or fragrance.
  • the bars may also consist in whole or part of inert ingredients and provide e.g. a massage or exfoliation type action and the like.
  • the cleansing kit further includes a set of instructions relating to the use of the kit.
  • the first and second compositions in the kit have a rigidity index greater than about 0.2 Mpa at 25°C.
  • the cleansing composition it advantageously includes an amphoteric surfactant, and preferaly about 15 % to 80 % by wt. of a C8 to C24 acyl isethionate, or about 15 % to 80 % by wt. of a soap.
  • the benefit composition advantageously includes an emollient selected from silicone oils and gums, fats, triglyceride oils, waxes, hydrophobic plant extracts, fatty esters, hydrocarbons and blends thereof, as well as other useful emollients listed below.
  • the benefit composition advantageously includes a component selected from vitamins, antimicrobial agents, acne medications, exfoliating agents, astringents, antioxidants, enzymes, sunscreens and ultraviolet radiation absorbing compositions and the like.
  • the closable receptacle and plurality of cosmetic compositions are contained in a container partitioned to separate the receptacle and the plurality of cosmetic compositions for ease in selection by the consumer.
  • the closable receptacle is formed of a polymeric mesh material.
  • FIG. 1 A preferred embodiment of the inventive cleansing kit 60 is depicted in Fig. 1 .
  • the customized cleansing implement may be supplied partially pre-assembled or preferably in components as illustrated in Fig. 1 to be assembled by the user according to instructions supplied with kit 60.
  • the user will select and insert, as desired, one or more of a cleansing bar 24, a fragrance bar 26, a conditioning bar 28, and an active agent bar 30 into bag holder 40 all contained in container 64.
  • pull ties 56 may be pulled so that together with cord locking device 58 will serve to keep the bars inside the bag holder 40 during use until the bars are either exhausted or until such time as the user desires to use a new selection of bars in the kit by either adding, removing or replacing any of the bars in any combination desired.
