Abstract

PURPOSE:To obtain a wiping and cleaning agent for removing nail enamels, etc., with hardly any irritant smell and skin irritation and capable of moderating degreasing of nails or the skin by blending a stock solution containing water, an organic solvent, a surfactant and a higher alcohol with a propellant such as liquefied petroleum gas. CONSTITUTION:The objective cleaning and wiping agent is obtained by blending (A) 70-95 pts.wt. stock solution containing (i) 40-60 pts.wt. water, (ii) 60-40 pts.wt. (preferably 42-52 pts.wt.) organic solvent such as acetone or methyl ethyl ketone, (iii) 5-10 pts.wt. (preferably 4-10 pts.wt.) surfactant such as sorbitan monolaurate or an aqueous solution of lauryldimethylaminobetaine and (iv) 0.5-5 pts.wt. (preferably 1-4 pts.wt.) higher alcohol such as >=16C cetanol with (B) 30-5 pts.wt. propellant composed of liquefied petroleum gas and/or dimethyl ether.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing agent, especially a nail enamel remover (nail enamel remover) and a skin cleansing agent.

[0002]

2. Description of the Related Art A wiping agent, for example, a nail enamel remover contains a large amount of an organic solvent, which has a pungent odor due to its volatility and also has an irritating effect on the skin. Degreasing of nails and skin occurred.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to develop a wiping agent having an equivalent effect with a small amount of organic solvent used as compared with a conventional product. As a result of intensive studies, the present inventors have found that when the dosage form of the wiping agent is changed from a conventional organic solvent-based liquid form to a mousse type (creamy foam) in which water is mixed in an organic solvent at a specific ratio, the irritating odor is alleviated. The inventors have found that the skin is less irritating, degreasing of nails and skin does not occur, and that the wiping effect is equivalent to that of the conventional product, and the above-mentioned problems have been solved.

[0004]

The present invention is based on the above knowledge, and 40 to 60 parts by weight of water, 60 to 40 parts by weight of an organic solvent,
Surfactant 5 to 10 parts by weight, and higher alcohol 0.5 to 5
70-95 parts by weight of stock solution containing 10 parts by weight and liquefied petroleum gas and / or dimethyl ether as propellant 30-5
Foam-type cleaning agent consisting of wt%.

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 of removing organic substances using this cleaning agent. The nonionic surfactants used in the present invention include sorbitan monolaurate (NIKKOL SL-10), 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) ) Etc. As a zwitterionic surfactant, there is lauryldimethylaminoacetic acid betaine aqueous solution (35%) (NIKKOLAM-301).

Higher alcohols generally have carbon numbers
16 or more are used, and examples thereof include cetanol, stearyl alcohol, behenyl alcohol, and oleyl alcohol. The proportion of each component in the wiping solution stock solution of the present invention is generally 40 to 60% by weight of an organic solvent, preferably 42 to 52% by weight, a surfactant of 2 to 12% by weight, preferably 4 to 10% by weight, and a higher alcohol 0.5. ~ 5% by weight, preferably 1-4
% By weight and the balance water.

70 to 95 parts by weight of the above-mentioned stock solution in a product and 30 to 5 parts by weight of liquefied petroleum gas and / or dimethyl ether as a 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 (creamy foam) cannot be obtained. The surfactant is
One to two or more of the above active agents are combined and used in an undiluted solution in an amount of 2 to 12 parts by weight. If it is less than 2% by weight, a good quality mousse (creamy foam) is unlikely to be formed, and if it is added in an amount of 12% or more, the effect does not change and stickiness such as stickiness occurs.

[0008] Higher alcohol is added to stabilize the foam quality and a mousse can be obtained without necessarily adding it, but in order to prevent foam dripping and to keep it stably attached to the nail or skin. It is preferable to add 1 to 4 parts by weight.
The ratio of the stock solution to the propellant is appropriately 30 to 5 parts by weight as the propellant. If it is 5 parts by weight or less, the foam quality is deteriorated during use or at a low temperature, and if it is 30 parts by weight or more, only the injection gas remains as it is used, which is uneconomical. Further, the blending ratio of liquefied petroleum gas and dimethyl ether can finely adjust the foam quality according to the intended use.

In addition to the above-mentioned components, the wiping agent of the present invention includes, for example, nail nutrients, skin nutrients, hydrolyzed collagen,
Additives such as various vitamins, preservatives, abrasive fine particles, pigments, fragrances and antioxidants can be contained. In order to produce the wiping agent of the present invention, the above-mentioned formulation stock solution is filled in a container,
Install valve and fill with propellant. Further, a spout or an actuator is attached for injection to obtain a product.

When the cleaning agent of the present invention is used, the mousse-type cleaning agent is placed on the organic substance to be removed, for example, nail enamel on the nails, oil stains on the skin such as hands and arms, and the like for a while. After leaving it for a while, paper, cotton,
Wipe off the mousse with a rag. In this case, compared with conventional liquid products, the cleaning agent can be applied directly without soaking into cotton etc., and there is no waste, and since liquid does not drip, liquid drip near the place of use and stains etc. Is prevented from occurring.

[0011]

The present invention will be described in more detail by 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 make 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]
Fill a container in the same manner as 3 and attach a valve and a spout to obtain a product. The foam state of these products, the degree of irritating odor, the efficacy, and the effect of preventing degreasing of nails and skin from Example 1,
It is shown in Table 1 together with the cases of 2 and 3.

The degree and effect of irritating odor were evaluated by comparing 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 irritation odor and skin irritation, and is particularly preferable from the viewpoint of occupational safety and environmental protection. The mousse-type cleaning agent of the present invention can be directly applied to nails and the like, is convenient and does not drip.
