Then the application of the composition becomes difficult, especially because the high volatility allows the polish remover to reside on the applicator only for a short period of time. This means that the types of suitable applicators are very limited.
Furthermore, the acetone based nail polish removers can dry out the fingernails. The acetone itself may penetrate through the skin and is known to be harmful to the liver. A wide variety of nail polish removers are known in the art. These products include conventional solvents such as acetone and ethyl acetate, and also include creams, paste, or gels containing suitable polish removal chemicals. Conventional products, as such, cannot remove the polish efficiently without causing additional harm.
Additionally, acetone and ethyl acetate along with a nail polish remover containing the same are flammable and dangerous to transport. The flammable problem continues into the consumer end product. It is clearly desired that this problem be avoided.
Thus it may be seen that acetone, which forms a base for most nail polish removers, is a constituent capable of causing a number of problems. Also, acetone has an odor which is very obnoxious and cannot be breathed in an enclosed space without damage to lungs. Generally, the acetone based removers with or without ethyl acetate are extremely volatile, flammable, harsh, drying, and irritating to the nails and surrounding cuticles. It is desirable to eliminate these problems. SUMMARY OF THE INVENTION

These and other objectives (which other objectives. become clear by considering the specification and claims as a whole) of this invention are met by providing a composition for removing nail polish including at least one mono or di glycol ether, at least one mono or di glycol ether ester, and a mixture thereof.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The low volatility solvents of mono and di glycol ethers, mono and di glycol ether esters, or mixtures thereof provide an effective compostion for removing nail polish. Typical of the esters used are cellosolve acetate, butyl cellosolve acetate, and methyl propasol acetate. Typical of the ethers used are cellosolve, propyl cellosolve, butyl cellosolve, and methyl propasol. Mixtures of these ingredients remove nail polish
completely and effectively. This removal by the compositions herein is accomplished while at the same time being gentle to nails and cuticles. The cuticles and nails are not dried out by the composition — but instead are softened and moisturized. Furthermore, the composition does not make nails brittle.
Generally speaking, the ethers are present in the amount of 1% to 99% by weight of the nail polish remover. Likewise, the esters are present in an amount of 1% to 99% by weight of the nail polish remover. More preferred, the ether is present in the amount of 30% to 70% by weight of the nail polish remover and the ester is present in the amount of 30% to 70% by weight of the nail polish remover. Even more preferred, the ether is present in the amount of 40% to 60% by weight of the nail polish remover and the ester is present in the amount of 40% to 60% by weight of the nail polish remover.
In a most preferred formulation, the ester is present in the amount 45% to 55% by weight of the nail polish remover. By the same token, the the ether is present in the amount of 45% to 55% by weight of the nail polish remover.
Other ingredients for the nail removal composition of this invention include conventional cosmetically acceptable excipients. Typical of these excipients are coloring agents, perfumes, fragrances, viscosity raising agents, emollients, and additives. It is feasible to add at least one excipient to the nail polish remover in the amount of 0% to about 5% percent by weight of the nail polish remover. More preferably, the amount of excipient is up to about 5% percent by weight of the nail polish remover.
Typical emollients are propylene glycol, block
copolymers of propylene glycol, polyoxypropylene, and polyoxyeth lene, generic polyglycols, and mixtures thereof. It is also permitted to add an amount of fragrance suitable to provide a pleasant odor to the product. Such fragrances are well known in the art. Typical of the other additives are mineral oil, collagen, hydrolyzed animal protein, dibutyl phthalate, isopropyl alcohol, and color. The appropriate amounts are a matter of choice and selection and easily determined.
Preferred of the mono and di glycol ethers are propyl cellosolve, butyl cellosolve, methyl propasol and mixtures thereof. Preferred of the mono and di glycol ether esters are butyl cellosolve acetate, cellosolve acetate, methyl propasol acetate and mixtures thereof. Of the ethers, the most preferred ether is propyl cellosolve. The most preferred ester is methyl propasol acetate. It is this combination of propyl cellosolve and methyl propasol acetate that gives the most desired results.
The nail polish remover may be applied in any suitable fashion. It may be in the form of saturated pads stacked and stored in a jar, which pads may be rubbed on the nails. The composition of the nail polish remover also may be brushed on, or applied by a sponge or sponge-like applicator. It may further be packaged in a bottle and used to saturate a cotton ball, which is then rubbed on the nails.
Typical other application devices and methods are shown in U.S. Patent Number 4,022,228 to Ropp et al; U.S. Patent Number 4,466,452 to Ferrari; U.S. Patent Number 4,440,181 to Scherer; U.S. Patent Number 4,474,195 to Warner; U.S. Patent Number 4,282,891 to Duceppe; U.S. Patent Number 3,369,553 to Keesee; U.S. Patent Number 4,321,936 to Chaconas; U.S. Patent Number
4,397,324 to Thomas; U.S. Patent Number 4,699,161 to Smith et al. Also U.S. Patent Number 4,530,726 to Montiel shows an application of nail polish remover.. Thus it may be seen that this composition is suitable for application by any appropriate method or device.
This composition may also be applied by saturated pads or absorbent sheets. The sheet applicators may be of the pull up type typical of baby wipes and hand/face wipes. These additional packaging forms and application methods, heretofore not practical prior to the disclosed formulation due to the high volatility of existing formulations, are now feasible because of the low volatility of the disclosed formulation.
The following examples are intended to illustrate without unduly limiting the invention. All parts and percentages are defined by weight of the total composition unless otherwise specified.
