Magnetically-oriented cosmetic fibers
View Patent ↗There is provided a dissolvable film polymer matrix that includes a plurality of magnetically responsive kertin-like fibers for application to an individual's face or head. The dissolvable film polymer matrix product includes hairs that are magnetically oriented in a non-random plain to be applied on an individuals face or head to simulate the appearance of the individual's natural hair. Methods of manufacturing and applying the dissolvable polymer matrix product are also disclosed.
1. A product for creating or enhancing the appearance of keratin fibers comprising:
(a) a solid or semi-solid film composed of one or more water-dissolvable polymers having a plurality of magnetic responsive fibers that have been magnetically oriented, prior to application to an individual's eyebrow, in a non-random direction and embedded in said film, wherein said film is in an eyebrow-like shape; and
(b) a backing sheet on which said film is disposed; and
(c) a peelable cover sheet for protecting said film prior to application;
wherein when applied to the individual's eyebrow, the plurality of magnetic responsive fibers adhere thereto in said non-random direction by said water-dissolvable polymers.
2. The product according to claim 1 , where said magnetic responsive fibers comprise nylon fibers.
3. The product according to claim 2 , where said nylon fibers are coated with iron oxide.
4. The product according to claim 3 , where said iron oxide is magnetite.
5. The product according to claim 1 , where said water-dissolvable polymer is selected from the group consisting of: water-soluble hydroxypropylmethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, polyvinyl pyrrolidone, carboxymethyl cellulose, sodium carboxy methyl cellulose, methyl cellulose, polyvinyl alcohol, sodium alginate, polyethylene glycol, xanthan gum, tragacantha, guar gum, acacia gum, arabic gum, carrageenan, pullulan, chitosan, polyacrylic acid, methylmethacrylate copolymer, carboxyvinyl copolymers, and/or mixtures thereof.
6. The product according to claim 2 , where said magnetic responsive fibers further include a colorant.
7. A method for preparing the product of claim 1 for creating or enhancing the appearance of keratin fibers comprising:
(a) applying an external magnetic field to an aqueous mixture of one or more water-dissolvable polymers and plurality of magnetic responsive fibers in a flat pan so as to orient the fibers in a non-random manner;
(b) removing the aqueous solvent by heating the composition in said flat pan to form a solid or semi-solid film having a plurality of magnetically responsive fibers oriented in a non-random direction and embedded in said film, and
(c) cutting the film into eyebrow-like shape for application to an individual's eyebrows;
wherein when applied, the plurality of magnetic responsive fibers adhere to the individual's eyebrows in said non-random direction by said water-dissolvable polymers.
8. The method according to claim 7 , where the magnetic responsive fibers are pretreated with iron oxide.
9. The method according to claim 8 , wherein the iron oxide is magnetite.
10. A method for applying the keratin fiber enhancing film of claim 1 comprising:
(a) wetting the surface of an area on an individual's eyebrows;
(b) positioning a keratin fiber enhancing film on the wetted surface, said film comprising a plurality of magnetic responsive fibers that have been magnetically oriented, prior to application to the individual's eyebrows, in a non-random direction and a water dissolvable polymer; and
(c) allowing the film to dissolve;
to thereby adhere the plurality of magnetic responsive fibers in said non-random direction to said individual's eyebrows by said water-dissolvable polymer.
11. The method according to claim 10 , where the adhered fibers are oriented in a single direction to simulate the appearance of the individual's hair.
12. The method according to claim 10 , where said fibers are magnetic responsive fibers.
13. The method according to claim 12 , where said magnetic responsive fibers comprise nylon fibers.
14. The method according to claim 13 , where said nylon fibers are coated with iron oxide.
15. The method according to claim 14 , where said iron oxide is magnetite.
16. The method according to claim 10 , where said film comprises a matrix composed of water-dissolvable polymers selected from the group consisting of: water-soluble hydroxypropylmethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, polyvinyl pyrrolidone, carboxymethyl cellulose, sodium carboxy methyl cellulose, methyl cellulose, polyvinyl alcohol, sodium alginate, polyethylene glycol, xanthan gum, tragacantha, guar gum, acacia gum, arabic gum, carrageenan, pullulan, chitosan, polyacrylic acid, methylmethacrylate copolymer, carboxyvinyl copolymers, and/or mixtures thereof.
