Abstract

Compositions and methods of this disclosure include liquid cosmetic compositions, for example, an eyeliner, that is applied to the surface of a user (e.g., a person), the surface including, for example, an eyelid, the liquid cosmetic product including a ferromagnetic component that is capable of being attracted by and attached to a magnet, the magnet part of a false eyelash.

Claims (37)

1. A liquid eyeliner composition, comprising:

a. a styrene/acrylates copolymer in an amount of from about 15 wt % to about 25 wt %; and

b. iron oxide in an amount of from about 35 wt % to about 45 wt % sufficient to being attracted by and attached to a magnet and wherein a point of attachment for a false eyelash including a magnetic element is provided,

wherein the composition has a viscosity of from about 950 cps to about 1300 cps at about 25° C. and a pH of from about 7.5 to about 8.5.

2. The liquid eyeliner composition of claim 1 , wherein the styrene/acrylates copolymer is in an amount of about 20 wt %.

3. The liquid eyeliner composition of claim 1 , wherein the iron oxide is in an amount of about 40 wt %.

4. The liquid eyeliner composition of claim 1 , wherein the composition has a viscosity of about 1100 cps at about 25° C.

5. The liquid eyeliner composition of claim 1 , further including a dispersing agent in an amount of from about 0.5 wt % to about 1 wt %.

6. The liquid eyeliner composition of claim 1 , further including a dissolvent in an amount of from about 1 wt % to about 3 wt %.

7. The liquid eyeliner composition of claim 1 , further including a preservative in an amount of from about 0.5 wt % to about 1 wt %.

8. The liquid eyeliner composition of claim 1 , further including a skin coloring agent.

9. A false eyelash prosthetic combination, comprising:

a false eyelash prothesis comprising:

a base including at least one magnet element; and

eyelash elements extending from the base, and

an eyeliner composition attracted by and attached to the at least one magnet element of the false eyelash prothesis comprising:

a styrene/acrylates copolymer in an amount of from about 15 wt % to about 25 wt %; and

iron oxide in an amount of from about 35 wt % to about 45 wt % sufficient to being attracted by and attached to the at least one magnet element and providing at least one point of attachment for the false eyelash to the eyeliner composition, wherein the composition has a viscosity of from about 950 cps to about 1300 cps at about 25° C. and a pH of from about 7.5 to about 8.5.

10. The false eyelash prosthetic combination of claim 9 , wherein the styrene/acrylates copolymer and iron oxide are cosmetically-acceptable.

11. The false eyelash prosthetic combination of claim 9 , wherein the styrene/acrylates copolymer is in an amount of about 20 wt %.

12. The false eyelash prosthetic combination of claim 9 , wherein the iron oxide is in an amount of about 40 wt %.

13. The false eyelash prosthetic combination of claim 9 , wherein the eyeliner composition has a viscosity of about 1100 cps at about 25° C.

14. The false eyelash prosthetic combination of claim 9 , wherein the iron oxide is milled iron oxide.

15. The false eyelash prosthetic combination of claim 14 , wherein the milled iron oxide is in an amount of about 40 wt %.

16. The false eyelash prosthetic combination of claim 9 , wherein the eyeliner composition further includes a dispersing agent in an amount of from about 0.5 wt % to about 1 wt %.

17. The false eyelash prosthetic combination of claim 9 , wherein the eyeliner composition further includes a dissolvent in an amount of from about 1 wt % to about 3 wt %.

18. The false eyelash prosthetic combination of claim 9 , wherein the eyeliner composition further includes a preservative in an amount of from about 0.5 wt % to about 1 wt %.

19. The false eyelash prosthetic combination of claim 9 , wherein the eyeliner composition further includes a skin coloring agent.

20. A liquid eyeliner composition, comprising:

a. water in an amount of 31.2 wt %;

b. a styrene/acrylates copolymer in an amount of 20 wt %;

c. butylene glycol in an amount of 5.0 wt %; and

d. PEG-40 hydrogenated castor oil in an amount of 2.0 wt %;

e. alcohol denatured in an amount of 1.0 wt %;

f. phenoxyethanol in an amount of 0.8 wt %; and

g. iron oxide in an amount of 40 wt %,

wherein the composition has a viscosity of from about 950 cps to about 1300 cps at about 25° C. and a pH of from about 7.5 to about 8.5.
