Abstract

Compositions (1) that provide a carrier (2) to covey a plurality of capsules (3) containing materials) (4) released to generate perceivable sensorial indicia discrete event occurrence and which can further provide perceivable sensorial reinforcers as incentives or disincentives to composition use coincident with such discrete events.

Claims

1. A composition, comprising:

a. an aqueous carrier;

b. a plurality of capsules entrained in said aqueous carrier, wherein each of said capsules contain an amount of material, and wherein said each of said capsules has a capsule wall with at least one adjustable capsule rupture characteristic to vary delay of release of said material; and

c. a perceivable sensorial indicia generated by release of said material from said plurality of capsules coordinated with occurrence of a discrete event.

2. A composition as described in claim 1, wherein said plurality of capsules comprise a plurality of non-aqueous soluble capsules.

32. A composition as described in claim 2, wherein said at least one adjustable capsule rupture characteristic comprises a capsule wall thickness.

33. A composition as described in claim 32, wherein said at least one adjustable capsule rupture characteristic comprises a capsule size.

37. A composition as described in claim 33, wherein said capsule wall thickness is between about 10 microns and about 30 microns.

38. A composition as described in claim 37, wherein said capsule size is between about 60 microns and about 240 microns.

39. A composition as described in claims 38, wherein said composition comprises a hand washing agent.

45. A composition as described in claim 39, wherein said at least one capsule rupture characteristic of said plurality of capsules adjusts to release said material between about 5 seconds and about 30 seconds after commencement of a hand washing event.

46. A composition as described in claim 39, wherein said at least one capsule rupture characteristic of said plurality of capsules adjusts to release said material between about 5 seconds and about 15 seconds after commencement of a hand washing event.

47. A composition as described in claim 45, wherein said capsules are greater than about 100 microns in size.

48. A composition as described in claim 46, wherein said capsules are less than about 100 microns in size.

49. A composition as described in claim 46, wherein said perceivable sensorial indicia generated by release of said material from said plurality of capsules comprises color change of said aqueous carrier.

50. A composition as described in claim 49, wherein said discrete event comprises achievement of a therapeutic hand wash event.

51. A composition as described in claim 50, wherein said discrete event comprises elapse of a hand wash event of pre-determined duration.

52. A composition as described in claim 51, wherein said discrete event comprises elapse of a hand wash event having duration of time selected from the group of:

between about 5 seconds and about 10 seconds, between about 6 seconds and 11 seconds, between about 7 seconds and about 12 seconds, between about 8 seconds and about 13 seconds, between about 10 seconds and about 14 seconds, between about 111 seconds and about 15 seconds, about 5 seconds, about 6 seconds, about 7 seconds, about 8 seconds, about 9 seconds, about 10 seconds, about 11 seconds, about 12 seconds, about 13 seconds, about 14 seconds, about 15 seconds.

58. A composition as described in claims 52, wherein said aqueous carrier further comprises an amount of color change material responsive to pH change of said aqueous carrier.

59. A composition as described in claims 58, wherein said material within said plurality of capsules comprises an aqueous carrier pH alteration material.

60. A composition as described in claim 59, wherein said an amount of color change material responsive to pH change of said aqueous carrier comprises phenolphtalein.

61. A composition as described in claim 60, wherein said carrier comprises a mixture of polyethylene glycol, tridecyl polyoxyethylene ethanol, nonyl phenol polyoxyethylene ethanol, and phenolphthalein.

62. A composition as described in claim 61, wherein said carrier comprises a mixture of about 100 parts polyethylene glycol, about 15 parts tridecyl polyoxyethylene ethanol, about 5 parts nonyl phenol polyoxyethylene ethanol, and about 0.06 parts of a 1% (w/v) solution of phenolphthalein.

63. A composition as described in claim 62, wherein said carrier comprises a mixture of glycerin, tridecyl polyoxyethylene ethanol, dodecy phenol polyoxyethylene ethanol, and phenolphthlein.

64. A composition as described in claim 63, wherein said carrier comprises a mixture of about 150 parts glycerin, about 18 parts tridecyl polyoxyethylene ethanol, about 10 parts dodecy phenol polyoxyethylene ethanol, and about 0.08 parts of a 1% (w/v) solution of phenolphthlein.

65. A composition as described in claim 64, wherein said amount of material contained by said plurality of capsules comprises trisodium phosphate.

66. A composition as described in claim 65, wherein said capsules are formed from a capsule material selected from the group consisting of a urea-formaldehyde, a polyvinyl acetate, a vinylidene chloride-methyl acrylate copolymer, a Daran 159 Latex, a polyvinyl methyl ether/maleic anyhydride colpolymer, a cellulose acetate butyrate, Celvol 107, a fully hydrolyzed polyvinyl alcohol, and a cellulose acetate propionate.
