Abstract

A liquid, non-aqueous cleaner composition that is well suited for removing finger nail polish, the composition comprising d-limonene, N-methyl pyrrolidone and cetyl acetate.

Claims

1. A fingernail polish remover and a finger artificial nail tip remover non-aqueous composition consisting essentially of the following ingredients:

a) d-limonene

b) about 25 to 45 weight percent of N-methyl-2-pyrrolidone

c) about 1 to 15 weight percent cetyl acetate, the d-limonene being at least 50% by weight of the composition.

6. A composition as defined in claim 1 that is effective as a fingernail polish remover and as artificial fingernail tip remover, there being at least about 3 weight percent cetyl acetate.

8. A composition as defined in claim 1 in which 0.5 to 10 weight percent of the d-limonene is substituted for by an equal weight percent of ethyl lactate.

9. A composition as defined in claim 1 in which 0.5 to 10 weight percent of the d-limonene is substituted for by an equal weight percent of a mixture of ethyl lactate and methyl lactate wherein said mixture consists of about 3 to 55 weight percent methyl lactate, the balance of said mixture being ethyl lactate.

15. A method of removing a coating from a fingernail comprising:

a) applying the cleaning composition defined in claim 1 or claim 2 to the coating on the nail;

b) allowing the coated nail and composition to remain in contact for a time sufficient to loosen the coating from the nail, and

c) separating the coating and the composition from the nail.

2. A non-aqueous cleaning composition consisting essentially of the following ingredients in approximate percent by weight:

space="preserve" listing-type="tabular">______________________________________ Ingredients % by weight ______________________________________ 1. d-limonene 40-70 2. N-methyl pyrrolidone 25-45 3. cetyl acetate 3-10 ______________________________________

3. A composition as defined in claim 2 in which the following ingredients are present in approximate percent by weight:

space="preserve" listing-type="tabular">______________________________________ Ingredients % by weight ______________________________________ 1. d-limonene 55-65 2. N-methyl pyrrolidone 30-40 3. cetyl acetate 4-6 ______________________________________

4. A composition as defined in claim 2 consisting essentially of containing about 60 weight percent d-limonene, 35 weight percent N-methyl pyrrolidone, and 5 weight percent cetyl acetate.

5. A composition as defined in claim 2 in which 0.5 to 10 weight percent of the d-limonene is substituted for by an equal weight percent of ethyl lactate.

7. A composition as defined in claim 2 in which the d-limonene is the major component in the composition.

10. A composition as defined in claim 2 in which 0.5 to 10 weight percent of the d-limonene is substituted for by an equal weight percent of a mixture of ethyl lactate and methyl lactate wherein said mixture consists of about 3 to 55 weight percent methyl lactate, the balance of said mixture being ethyl lactate.

11. A non-aqueous liquid composition consisting essentially of about 50% by weight of d-limonene, about 25% by weight of N-methyl pyrrolidone, about 5% by weight of a mixture of cetyl acetate and acetylated lanolin alcohol wherein said mixture consists of from about 0.5 to 30% by weight of acetylated lanolin alcohol, the balance of said mixture being cetyl acetate, about 10% by weight of ethyl lactate, and about 10% be weight of methyl lactate.

12. A non-aqueous cleaning composition consisting of about 5 to 75% by weight of d-limonene, about 5 to 95% by weight of N-methyl-2-pyrrolidone, and about 1 to 15% by weight of a mixture of cetyl acetate and acetylated lanolin alcohol wherein said mixture consists of from about 0.5 to 30% by weight of acetylated lanolin alcohol, the balance of said mixture being cetyl acetate.

13. A non-aqueous cleaning composition consisting of about 5 to 75% by weight d-limonene, about 5 to 95% by weight of N-methyl-2-pyrrolidone and about 1 to 10% by weight of cetyl acetate.

14. A non-aqueous cleaning composition consisting of the following ingredients in approximate percent by weight:

space="preserve" listing-type="tabular">______________________________________ Ingredient % by weight ______________________________________ d-limonene 40-70 N-methyl-2-pyrrolidone 25-45 mixture of cetyl acetate and 3-10 acetylated lanolin alcohol ______________________________________
