1. A substrate with a particulate cosmetic applied thereto produced by a method comprising the following steps:
(a) forming a slurry of microcapsules of said cosmetic by combining said cosmetic, a liquid carrier and a film forming component, said film forming component provided in an amount effective to microencapsulate and bind said cosmetic to a substrate when said carrier evaporates;
(b) adding a plasticizer in an amount effective to prevent said film forming component from altering the texture of said cosmetic after said carrier has evaporated;
(c) applying said slurry to said substrate;
(d) evaporating said carrier to thereby form a microencapsulated cosmetic adhered to said substrate wherein said cosmetic comprises insert particulate matter, coloring agents and fragrances and wherein said effective amount of the film forming component is less than about 12% based on the total of said film forming component o a solid basis and said inert particulate matter.
2. The article of claim 1 wherein said film forming component is selected from the group consisting of polyvinyl pyrrolidone, polyvinylalcohol, polyurethane, SBR block copolymers, cellulose, methylcellulose, silicone and mixtures thereof.
7. The article of claim 1 wherein said slurry is formed by adding said plasticizer to said carrier with agitation; and
said film forming component is added to said carrier and plasticizer with agitation to form a film forming component containing mixture; and
said cosmetic is added to said film forming component containing mixture with agitation to form encapsulated particles of cosmetic and said final mixture is subsequently homogenized without reducing the particle size of said cosmetic.
8. The article of claim 1 wherein said slurry is extruded onto said substrate.
13. A substrate with a particulate cosmetic applied thereto wherein said cosmetic comprises inert particulate matter, coloring agents and fragrances, produced by a method comprising the following steps:
(a) forming a slurry of microcapsules of said cosmetic by combining said cosmetic, a liquid carrier and a film forming component, said film forming component provided in an amount effective to microencapsulate and bind said cosmetic to a substrate when said carrier evaporates wherein said substrate is a first sheet;
(c) applying said slurry to said first sheet;
(d) evaporating said carrier to thereby form a microencapsulated cosmetic adhered to said first sheet;
(e) binding a second sheet to said first sheet with said microencapsulated cosmetic between said first sheet and said second sheet wherein said film forming component maintains said microencapsulated cosmetic adhered to said first sheet but prevents said microencapsulated cosmetic from adhering to said second sheet.
14. The article of claim 13 wherein said cosmetic comprises 70-90 percent inert particulate matter and said slurry comprises about:
Cosmetic--35-65 PBW
Film Forming Component--0.1-5 PBW
Carrier--1-65 PBW
Plasticizer--0.1-10 PBW.
15. The article of claim 14 comprising:
Cosmetic--49.0 PBW
Polyvinyl pyrrolidone--0.6 PBW
Ethanol--48.2 PBW
Water--1.0 PBW
Polydimethysiloxane--0.6 PBW
Isopropyl myristate--0.6 PBW.
16. A substrate with a non-dry cosmetic applied thereto produced by a method comprising the following steps:
(a) forming discrete microencapsulated particles of said non-dry cosmetic;
(b) forming a slurry by combining said discrete particles of said cosmetic with a liquid carrier and a film forming component, said film forming component provided in an amount effective to microencapsulate said discrete particles and bind said particles to a substrate when said carrier evaporates;
wherein said slurry comprises 30-65 parts by weight
microencapsulated particles, 0.1-10 parts by weight
plasticizer, 0.1-5 parts by weight film forming
component, and 1-65 parts by weight carrier;
(c) applying said slurry to said substrate wherein said substrate comprises a first sheet;
(d) evaporating said carrier to thereby form microencapsulated microcapsules of said cosmetic adhered to said substrate;
(e) covering said first sheet with a cover sheet co-extensive with said first sheet whereby said film forming component acts to adhere said microencapsulated particles of said non-dry cosmetic to said first sheet and acts to prevent said microencapsulated particles of said non-dry cosmetic from adhering to said cover sheet.
17. The article of claim 16 wherein said discrete particles of said non-dry cosmetics are gelatin encapsulated.
