DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiping agent, in particular, a nail polishes remover (nail enamel remover) and a wiping agent for skin.

[0002]

2. Description of the Related Art A cleaning agent such as a nail enamel remover contains a large amount of an organic solvent, and has a pungent odor due to its volatility and also has an irritating property to the skin. Degreasing of nails and skin occurred.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to develop a wiping agent having the same effect with a smaller amount of organic solvent used than conventional products. The present inventors have conducted intensive studies and found that when the dosage form of the wiping agent is changed from a conventional liquid mainly composed of an organic solvent to a mousse-like (creamy foam) in which water is mixed at a specific ratio with an organic solvent, an irritating odor is reduced. In addition, the present inventors have found that the skin is less irritating, does not cause degreasing of nails and skin, and has the same wiping effect as a conventional product.

[0004]

SUMMARY OF THE INVENTION The present invention is based on the above findings, and comprises 40 to 60 parts by weight of water, 60 to 40 parts by weight of an organic solvent,
5 to 10 parts by weight of surfactant and 0.5 to 5 of higher alcohol
70-95 % by weight of a stock solution containing parts by weight and liquefied petroleum gas and / or dimethyl ether 30-5 as a propellant
Removal of foam-like wipes or nail polish by weight
Provide the agent.

[0005] Examples of the organic solvent used in the present invention include aliphatic ketones such as acetone and methyl ethyl ketone. The present invention is further a method for removing organic substances using the wiping agent. Examples of the surfactant used in the present invention include nonionic surfactants such as sorbitan monolaurate (NIKKOL SL-10) and polyoxyethylene (20) sorbitan monolaurate (NIKKOL TL-1).
0), polyoxyethylene (20) stearyl ether (N
IKKOL BS-20), polyoxyethylene (2) cetyl ether (NIKKOL BC-2), polyoxyethylene (40) lanolin alcohol (NIKKOL BWA-40), polyoxyethylene (40) hydrogenated castor oil (NIKKOL HCO-40) ). As a zwitterionic surfactant, there is an aqueous solution of betaine lauryldimethylaminoacetate (35%) (NIKKOLAM-301).

[0006] Higher alcohols generally have a carbon number
Sixteen or more are used, for example, cetanol, stearyl alcohol, behenyl alcohol, oleyl alcohol and the like. The proportion of each component in the stock solution of the wiping agent of the present invention is generally 40 to 60% by weight, preferably 42 to 52% by weight of an organic solvent, 2 to 12% by weight of a surfactant, preferably 4 to 10% by weight, and 0.5% of a higher alcohol. -5% by weight, preferably 1-4
Wt%, and the balance water.

The stock solution comprises 70-95 % by weight of the product and 30-5 % by weight of liquefied petroleum gas and / or dimethyl ether as propellant. When the organic solvent is less than 40% by weight, the wiping effect is low, and when it exceeds 60% by weight, a mousse-like (creamy foam) cannot be obtained. The surfactant is
2 in stock in combination the active agent one or more
Use up to 12 % by weight . If it is less than 2% by weight, good quality mousse-like (creamy foam) is unlikely to be formed, and even if it is added in an amount of 12% or more, the effect does not change and adverse effects such as stickiness occur.

[0008] The higher alcohol is added to stabilize the foam quality, and a mousse can be obtained without necessarily adding it. However, it is necessary to prevent foam sagging and stably adhere to nails and skin. It is preferable to add 1 to 4 parts by weight.
The ratio between the stock solution and the propellant is suitably 30 to 5 parts by weight as the propellant. If the amount is less than 5 parts by weight, the foam quality is reduced during use or at a low temperature. The blending ratio of liquefied petroleum gas and dimethyl ether can finely adjust the foam quality according to the intended use.

[0009] In addition to the above-mentioned components, the wiping agent of the present invention includes, for example, a nutrient for nails, a nutrient for skin, hydrolyzed collagen,
It can contain additives such as various vitamins, preservatives, abrasive particles, pigments, fragrances, antioxidants and the like. To produce the wiping agent of the present invention, the above-mentioned stock solution is filled in a container,
Attach the valve and fill with propellant. Further, a spout or an actuator is attached for spraying to obtain a product.

When using the wiping agent of the present invention, a mousse-like wiping agent is placed on an organic substance to be removed, for example, a nail enamel on a nail, oil stains on the skin such as hands and arms, and the like. After leaving for a while, paper, cotton,
Wipe the mousse with a rag. In this case, compared to the conventional liquid products, the cleaning agent can be applied directly without soaking into cotton or the like, so that there is no waste and there is no liquid dripping. Is prevented from occurring.

[0011]

The present invention will be described in more detail with reference to the following examples.

[0012]

Example 1 Nail enamel remover mousse The following components are filled in an aerosol container, and a valve and a spout are attached to obtain a product.

[0013]

Example 2 The following components are filled in an aerosol container, and a valve and a spout are attached to obtain a product.

[0014]

Example 3 The following components are filled in an aerosol container, and a valve and a spout are attached to obtain a product. [Comparative Examples 1 and 2] The components shown in Table 1 were used in Examples 1 and 2,
Fill the container in the same manner as in 3, and attach a valve and a spout to obtain a product. Example 1 shows the foam state, the degree of irritating odor, the effectiveness, and the defatting prevention effect of nails and skin of these products.
The results are shown in Table 1 together with the cases of 2 and 3.

The degree and effectiveness of the irritating odor were evaluated in comparison with a conventional organic solvent-based nail enamel remover.

[0016]

[Table 1]

[0017]

According to the present invention, the same cleaning effect can be obtained with a smaller amount of the organic solvent used as compared with the conventional product. This small amount of organic solvent reduces irritating odor and irritation to the skin, and is particularly preferable in terms of occupational safety and environmental protection. The mousse-like wiping agent of the present invention can be directly applied to nails or the like, is easy to use, and does not drip.
