JPS62207206A - Nail enamel remover - Google Patents

Abstract

PURPOSE:The titled remover in a jelly form that is mainly, composed of gamma- butyrolactone, benzyl alcohol or their mixture, when needed, contains a jelly- forming agent, a skin or nail-protecting agent, a humectant and jelly-stabilizing agent. CONSTITUTION:Gamma-butyrolactone, benzyl alcohol or benzyl benzoate or their mixture is used as major constituents and the objective agent is prepared from these constituents or from the mixture thereof with a jelly-forming agent such as diethyl phthalate, a skin or nail-protecting agent such as squallan, a humectant for skin or nail such as DMSO or gel-stabilizer such as dibenzylidene sorbitol to give the objective remover in a jelly form. Since the nail enamel remover can be used by coating it on the nails with hands, there is no danger of spilling, further it is free from unpleasant smell and inflamma tion, and it caused no nail-whitening and cracking.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a nail enamel remover that does not damage (do not roughen) fingertips or nails even when used.

<Prior Art> Conventional nail enamel removers include
! Most of them were manufactured using a solvent as the main ingredient, so using them had the disadvantage of causing the nails to lose their claws or making the tips of the fingers rough. Therefore, it is necessary to treat rough nails and fingers separately, and there are other problems such as the smell of the solvent being too strong, and if accidentally spilled, the paint on the mirror table may peel off. I was in trouble.

<Problems to be Solved by the Invention> Therefore, it has been desired to develop a nail enamel remover that is less irritating, does not damage nails or fingers (skin), and is less likely to spill.

<Means for solving the problem> The present application uses (a) γ-butyrolactone and (b) γ-butyrolactone as the main ingredient.
Benzyl alcohol (or penzyl henzoate)
, (c) Using a mixture of γ-butyrolactone and Hensyl alcohol (or benzyl benzoate), the base ingredient alone or these base ingredients are combined with the jelly-forming agent described in the following (1) to (4), skin 1id The invention consists of a total of six inventions, which are manufactured by adding a (nail) protective agent, a skin (nail) moisturizing/protecting agent, and a jelly (gel) stabilizing nucleating agent.

(1) A jelly-forming agent whose main component is diethyl fucorate, hydroxypropylcellulose, or polyvinylpyrrolidone. (2) A skin (nail) protectant whose main component is natural or synthetic squalane. (3) A skin (nail) protectant whose main component is urea, or dimethyl sulfoxide (D
Moisturizing and protecting agent for the skin (nails) consisting of MSO
Gel) Stabilizing Nucleating Agent γ-Butyrolactone is produced by hydrogenating maleic anhydride.

The aforementioned jelly (gel) stabilizing nucleating agent, dibenzylidene sorbitol, is dissolved in dimethyl sulfoxide, which is a skin moisturizing and protective agent, in a range of 1 to 40%, and then this solution is added to a concentration of 5 to 40% of the total amount of the enamel remover. It is usually added within a range of 20%.

Moreover, the jelly-forming agent consisting mainly of hydrodipropylcellulose or polyvinylpyrrolidone is usually prepared as a 1 to 20% ethanol solution and added in an amount of 1 to 20% of the total amount of the enamel remover.

By adding an alcoholic solution of hydroxyproylcellulose and esters, the entire enamel remover becomes a viscous jelly, which can be filled into a tube and taken out in the required amount.

All of the substances described above have passed cosmetic raw material standards and are guaranteed to be safe for the human body.

The nail enamel remover according to the present application is sufficiently effective as an enamel remover with just the base ingredient, but in order to further enhance the effectiveness of use, the above-mentioned substances 8 having various functions are added.

An example of a method for producing a nail enamel remover by adding the above-mentioned substances is as follows.

In a temperature-adjustable reaction tank (set so that the product temperature is 50°C), put the base ingredients such as γ-butyrolactone and benzyl alcohol (mix them in advance when using both), and add them separately while stirring. Add a cerifying agent (1-20% ethanol solution) made of hydroxypropyl cellulose, polyvinyl pyrodone, etc., and stir thoroughly.
Mix. Furthermore, squalane, which is a skin protective agent, is added, and a 1-40% solution of dibenzylidene sorbitol, which is the jelly (gel) stabilizing nucleating agent described above, in dimethyl sulfoxide (skin moisturizing/protecting agent) is prepared separately. Gradually add/inject. After stirring for about 30 minutes, the flavoring agent is added, stirring and heating are stopped, and the mixture is left at room temperature to cool.

<Example 1> 30 parts of γ-butyrolactone and 25 parts of Hensyl alcohol
After stirring at 50 rpm for about 10 minutes in a reaction tank (temperature set at 50°C), NPC was prepared in a separate dissolution tank.
Add 20 parts of a 10% alcohol solution of. After stirring for another 10 minutes, 2 parts of synthetic suffuran was added, the stirring speed was increased to 1500 rpm, and 15 parts of a 20% DMS solution of dibenzylidene sorbitol prepared in a separate dissolution tank was poured into the mixture. do. At the same time, 5 parts of urea was added, and 3 parts of orange as a flavoring agent were added, and the stirring was continued for about 30 minutes, and when no free liquid was observed at the top, all operations were stopped. Serve freely at room temperature. The resulting product was transferred to a storage tank, and a portion was filled into tubes using a dispenser to become a commercial product.

Place one drop of the jelly-like liquid in this tube onto each of your five fingernails that have manicure enamel, and apply five drops to each nail using your other fingers.
Apply evenly and do the same to the other nail 5 times, 1
After ~2 minutes, I wiped my nails with a tissue or gauze and was able to remove the enamel cleanly. Although I did not wash my hands after dropping the enamel, no abnormalities were observed.

<Example 2> 25 parts of γ-butyrolactone and 30 parts of benzyl alcohol
The sample was placed in a reaction tank (temperature set at 50°C) and stirred at 80 rpm for about 10 minutes. To this, 20 parts of a 10% alcohol solution of a mixture of NPC and PvP (2:1) prepared separately in a dissolution tank was added, and after stirring for another 10 minutes, 2 parts of souffuran was added, and the stirring speed was increased to 2000 rpm. To this, add 5 parts of urea and 15 parts of a 20% DMSO solution of dibenzylidene sorbitol prepared in a separate dissolution tank.
Finally, 3 parts of strawberry as a flavoring agent were added, and the mixture was heated and stirred for about 30 minutes, and then brought to room temperature at lIMLt and filled into tubes to prepare a product.

Place one drop of the jelly-like liquid in this tube onto each of your five fingernails that have manicure enamel, and apply five drops to each nail using your other fingers.

Add 20 parts of P T 5% ethanol solution 1Fr, and add 1
After stirring for 0 minutes, 2 parts and 8 parts of sulfuran were added and stirred rapidly at a stirring speed of 2000 rpm, and to this was added 5 parts of urea, and 20 parts of a 15% DMSO solution of dibenzylidene sorbitol prepared in a separate dissolution tank. At the same time, 3 parts of coumarin, a flavoring agent, was added to the final product. Stir this at a stirring speed of 2
The mixture was rapidly heated and stirred at 000 rpm for about 30 minutes, and then allowed to cool to room temperature, filled into tubes, and used as a commercial product.

Smash it evenly and apply 60,000 evenly on the other nail in the same way, 1
After ~2 minutes, I wiped my nails with a tissue or gauze and was able to remove the enamel cleanly. Although I did not wash my hands after removing the enamel, no abnormalities were observed.

<Effects of the Invention> As is clear from the above examples, the nail enamel remover of the present application has the following characteristics compared to conventional products.

(1) It can be used by applying it directly to your nails. It is easier than conventional products, which required applying with absorbent cotton.

(2) Since it is not a liquid, there is no spillage when applying it; if you spilled the conventional product, the paint on the mirror stand would peel off.

(3) No unpleasant odor like conventional products.

(4) It is safe as it is hardly flammable.

(5) Preserves your nails without turning them white or cracking like with conventional products! Do i1[.
