Abstract

The composition includes a pigment and a binder; the pigment being present in a pigment volume concentration of between 69% to 75% of the non-volatile portion of the composition to create a physical action upon drying of a layer of the composition applied to fingernails and toe nails, wherein a lack of cohesive strength between the pigment and binder results in shrinking of the applied layer to form cracks, thereby visibly exposing a previously applied underlying nail polish through the formed cracks.

Claims

1. A cosmetic lacquer composition for application to fingernails and toe nails comprising:

a binder consisting of non-toxic, skin compatible ingredients;

a pigment consisting of non-toxic, skin compatible ingredients; and

the volume of concentration of said pigment in said composition causing the formation of random cracks in a layer of said composition when applied to a surface and upon drying of said applied layer.

2. A lacquer composition for application to fingernails and toe nails comprising:

a first mixture comprising n-butyl acetate, petroleum naphtha, 70 sec nitrocellulose (70%), isopropyl alcohol, maleated-rosin, propylene glycol methyl ether acetate, dipropylene glycol methyl ether, mineral spirits, amorphous silica, magnesium silicate, and ethyl acetate; and

a second mixture comprising color component, maleated-rosin, n-butyl acetate, acrylic resin, dipropylene glycol methyl ether, and ethyl acetate.

3. A lacquer composition as recited in claim 2 wherein a pigment in said composition comprises the color component, amorphous silica, and magnesium silicate.

4. A lacquer composition as recited in claim 3 wherein the pigment is present in a pigment volume concentration of between 69% to 75% of a non-volatile portion of said composition.

5. A cosmetic preparation for application to fingernails and toe nails comprising:

a base composition comprising petroleum naphtha, n-butyl acetate, 1/4 sec nitrocellulose (70%), isopropyl alcohol, 2-ethylhexyl diphenyl phosphate, #15 castor oil, propylene glycol methyl ether acetate, and ethyl acetate; and

a crackle lacquer composition comprising;

a first mixture comprising n-butyl acetate, petroleum naphtha, 70 sec nitrocellulose (70%), isopropyl alcohol, maleated-rosin, propylene glycol methyl ether acetate, dipropylene glycol methyl ether, mineral spirits, amorphous silica, magnesium silicate, and ethyl acetate; and

a second mixture comprising a color component, maleated-rosin, n-butyl acetate, acrylic resin, dipropylene glycol methyl ether, and ethyl acetate.

6. A cosmetic preparation as recited in claim 5 wherein a pigment in said composition comprises the color component, amorphous silica, and magnesium silicate.

7. A cosmetic preparation as recited in claim 6 wherein the pigment is present in a pigment volume concentration of between 69% to 75% of a non-volatile portion of said composition.

8. A method of manufacturing a cosmetic lacquer composition comprising the steps of:

providing a binder portion consisting of non-toxic, skin compatible ingredients;

providing a pigment portion consisting of non-toxic, skin compatible ingredients; and

combining said binder portion and said pigment portion so that said pigment portion is present in a volume of concentration which causes the formation of random cracks in an applied layer of said cosmetic lacquer composition upon drying thereof.

9. A method of decorating fingernails and toe nails comprising the steps of;

providing a cosmetic lacquer composition comprising;

a binder portion consisting of non-toxic, skin compatible ingredients;

a pigment portion consisting of non-toxic, skin compatible ingredients;

applying a layer of said cosmetic lacquer composition to a surface on a nail;

drying said applied layer; and

allowing random cracks to form in said applied layer.
