Description

The invention relates to the field of decorative cosmetology, and in particular to means for removing varnish from nails.

Known means for removing manicure varnish from nails, which are mixtures of various volatile solvents, which are an active principle, with targeted additives of fatty substances.

Known nail polish remover (US 5866104, 1999) that does not contain acetone. As a solvent, the product contains glycol esters and glycol ethers, and may also contain cosolvent (a co-solvent that increases the solubility of basic solvents). As the cosolvent, dihydric alcohols are used, in particular propylene glycol or 2-methyl-1,3-propanediol (preferably). The composition also includes water and targeted additives to soften, fragrance and give, if necessary, the desired color. Water is used to increase the adsorption and moisturizing ability of a liquid, and to reduce the cost of a product.

The disadvantage of the described tool is that it effectively removes only varnishes, the main components of which are cellulose derivatives - nitrates and acetates, while modern varnishes contain a wide range of different polymers.

Known nail polish remover (patent UA 42375, published March 15, 2005), containing an organic solvent of 15-70%, distilled glycerin of 1-3 wt.%, A biologically active additive based on ginseng 0.4-0 biomass, 5 wt.%, The rest is water.

Also known is a tool for removing nail polish from nails (RU 2201744, published April 10, 2003), containing glycol ether, dihydric alcohol or its derivatives as cosolvent, water, γ-butyrolactone and target additives in the form of fatty components as solvent (in including oil extracts of biologically active substances, for example, fir oil) and fragrances from extracts of natural products, in the following ratio of components, wt.%:

Glycol ether (ethyl, propyl - or butyl cellosol) 5-70 γ-butyrolactone 10-75 Dihydric alcohol or its derivatives 8-20 Water 10-20 Targeted Supplements 0.5-2

The disadvantage of these tools is that they are not universal enough, since they effectively remove varnishes that contain only some types of polymers, while the spectrum of modern manicure varnishes contains a much larger number of polymers. The disadvantage is that for the restoration of nails, only the fat component in the form of a biologically active additive is used. In the absence of an unpleasant odor, the likelihood of accidentally using the product in food increases.

The technical result to which the invention is directed is to provide a means for removing nail polish without an unpleasant odor, with a wide range of effective effects on various types of manicure varnishes, and also characterized by a restoring effect on the nails, and the inability to accidentally use the product in food.

The technical result is achieved in a nail polish remover containing propylene glycol as the main solvent, and cosolvents (cosolvents that increase the solubility of the main solvent) as ethyl alcohol, ethyl acetate, propylene carbonate, dimethyl glutarate, dimethyl adipate and isopropyl alcohol, and as additives for mitigation and restoration of nails a mixture of glycerin, gelatin, jojoba seed oil (close to natural skin fat, softens and soothes the skin) and toko Eryl acetate (vitamin E, which slows down the aging process of cells due to oxidation, accelerates the healing of burns), in addition, it contains water to increase the adsorption and moisturizing ability of the liquid, as well as the most bitter substance denatonium benzoate known in the world to prevent accidental use of the product in food. The tool is characterized by the following composition, wt.%:

water 25 propylene glycol 63 ethanol one ethyl acetate one propylene carbonate one dimethyl glutarate one dimethyl adipate one glycerol one gelatin one perfume one isopropyl alcohol one denatonium benzoate one jojoba oil one tocopheryl acetate (vitamin E) one

The technological process for the preparation of nail polish removers consists of the following operations.

In the calculated recipe quantities, the solvents, water and target additives are mixed, sequentially feeding them to the reactor. The composition is mixed for a predetermined time with a given intensity at room temperature. Then the resulting product is packaged in traditional containers or impregnated with sponges, napkins or tampons, which are placed in special containers with a tightly closed lid.

Example

The prepared product was tested when removing varnishes of various companies, differing in compositions containing only cellulose derivatives, as well as compositions additionally containing various polymers. Varnishes were applied to glass substrates, aged at 40 ° C for three hours, then a second layer of varnish was applied. This two-layer coating was aged for two days. After that, a test was conducted on the effectiveness of varnish removal. Tests have shown that a wide variation in solvents within the indicated limits does not significantly change the properties of the claimed agent.

All women who regularly used the proposed formulations for three months noted the mild action of the product, the absence of white coating on the nails after its use, the absence of inflammation of the nail roll, drying of the skin and nails, and delamination of the nail plates.

The proposed tool for removing varnish from nails effectively removes various types of varnishes, gently acts without damaging or drying nails and skin and without leaving a white coating after its use.
