Definitions

  • the present invention relates to low viscosity shower gel compositions (containing mild, high foaming surfactants and optionally emollients) and methods for efficiently delivering such compositions to implements or to the skin. More specifically, the invention relates to low viscosity shower gel compositions (i.e., having viscosity less than 3000 cps at 10s "1 measured by a standard viscometric method (e.g., Brookfield or Haake viscometers) , preferably less than 1000 centipoises (cps) ) which are delivered via a spray, preferably a simple non-aerating pump spray.
  • a standard viscometric method e.g., Brookfield or Haake viscometers
  • centipoises centipoises
  • shower gels are purposely formulated to have a high viscosity, generally greater than 3000 cps. This permits the dispensing of the product, by pouring from a bottle or squeezing from a tube, either onto a showering implement or directly onto the hands .
  • the high viscosity gel is generally then diluted with water and rubbed to form foam and lather.
  • the high viscosity is standard in all commercial shower gel preparations. However, it does present certain problems and creates a number of formulation limitations. In the gel form, for example, it is extremely difficult to achieve even coverage of the material over the surface of the body. Also, there is considerable waste involved as much of the gel is washed away before the gel dissolves to form a cleansing lather and foam. Finally, the gel requirement limits the use of certain agents that may deliver a benefit to the skin. Ethanol, for example, which will cool the skin, and glycerol, which will deliver moisturization, can be used in very limited amounts as they act as hydrotropes, drastically reducing the shower gel viscosity. A shower gel with greatly reduced viscosity can therefore provide a number of advantages unavailable to current forms if it can be efficiently delivered to either an implement or directly to skin.
  • the spray droplets generally have a size from 90 to 1000 microns, preferably from 100 to 300 microns.
  • the present invention provides the combination of a pump applicator for non-aeratmg spray and a surfactant-based composition, designed for showering and bathing together with the delivery of other benefits (e.g., cooling, moisturization).
  • benefits e.g., cooling, moisturization
  • U.S. Patent No. 5,597,792 to Klier et al . discloses a cleansing composition suitable for skin and hair cleansing which may be pumped.
  • the compositions are oils or continuous microemulsions, which are more suitable for hard surface cleansing rather than the mild, high foaming water continuous compositions of the present invention.
  • the present application is specifically concerned with water-continuous compositions.
  • U.S. Patent No. 5,346,639 to Hatfield teaches shampoo compositions dispersed from a spray dispenser wherein the compositions have a viscosity of less than 40 cps.
  • compositions of the invention maintain a low viscosity primarily by being substantially free of neutral thixotropic salts.
  • Compositions of the invention are not free of such salts and generally will comprise at least 0.1%, preferably from 0.1 to 1% of, for example, alkali metal salts.
  • hydrotropes such as are used in the subject invention
  • higher levels of salt e.g., introduced from certain surfactants and/or raw materials

  • Compositions of the invention may contain from 0 to 20% by wt . preferably from 0.5 to 10%, more preferably from 1 to 5% by wt . of such emollients.
  • compositions of the invention require from 5 to 40% of hydrotropes (e.g., glycerin or C 2 -C 6 alkanols) .
  • the compositions of the invention may tolerate higher, non-negligible amounts of salt/electrolyte and preferably contain hydrophobic emollient agents.
  • U.S. Patent No. 3,962,150 to Viola discloses aqueous skin cleansing compositions suitable for non- pressurized, aerated, low density foam cleansers.
  • foam is created as it is dispensed from the bottle. Foam is thus formed over only a finite area rather than throughout the entire area where it is sprayed (as is the case using the compositions of the present invention) .
  • the present invention relates to the combination of a low viscosity, hydrotrope-containmg personal wash composition (generally undesirable because it is "runny" and disperses too quickly) and a spray dispenser which allows the low viscosity liquid to be evenly dispersed without aeration (e.g., by using expending gases) .
  • the liquid s dispersed in small droplets (from 90 to 1000 microns) directly to the skin and without excessive waste.
  • efficient delivery allows desirable hydrotropes, which are often avoided (again, because they would make the composition too thin) , to incorporated into the compositions of the invention. It is believed that use of hydrotropes also permits higher levels of thixotropic salts to be tolerated, if desired.
  • the present invention provides a combination of a dispenser and a shampoo or personal wash composition, said combination comprising: (1) a non-aerating spray dispenser; and
  • a shampoo or personal wash composition having a viscosity of less than 3000 cps measured at 10 s"1 and comprising:
  • At least one surfactant selected from the group consisting of anionic, nonionic, amphoteric, and cationic surfactants and mixtures thereof;
  • the viscosity of the compositions is preferably less than 750 cps, preferably from about 5 to 500 cps, more preferably from about 5 to 200 cps measured at 10s "1 .
  • Suitable compositions include shampoos and personal wash compositions such as shower cleansers.
  • compositions of the invention can generally tolerate levels of thixotropic salts not tolerable in, for example, compositions without hydrotrope (generally the compositions may comprise from 0.1 to 10 salts, preferably from 0.1 to 5%, depending on choice and level of hydrotrope used) .
  • the level of oil/emollient is typically from 0 to 20%, preferably from 1 to 10%.
  • the liquid is spread smoothly and evenly across large cross-section of skin, yet does not foam only at site of first contact but over the entire skin cross-section.
  • the composition is evenly and rapidly dispersed over an area to which it is sprayed and provides a desired attribute over that area.
  • the present invention relates to low viscosity, hydrotrope-containing shampoo/personal wash shower composition in combination with a spray dispenser or applicator for non-aerating spray. While low viscosity spray compositions are known, they have previously been formed by minimizing concentration of neutral salt thixotropes (see column 2, line 62 of U.S. Patent No. 5,346,639 to Hatfield, for example), rather than through use of at least about 5% by wt . , preferably from 10 to 35%, more preferably from 15% to 35% by wt . of a hydrotrope.
  • the low viscosity compositions of the invention it is possible to efficiently dispense shampoo/personal wash compositions, which may contain relatively high levels of thixotropic salts and/or relatively high levels of oils/emollients through a non-aerating spray dispenser.
  • the thin shower cleansers or shampoos are evenly and readily dispersed (unlike thicker gel shampoos or shower cleansers which may be more difficult to apply) while still delivering desirable consumer attributes (e.g., moisturizer, feel) .
  • the non-aerated spray is believed to disperse over a wider area such that the surfactants create lather or foam much more rapidly than would happen in a gel composition.
