Description

Non-toxic and odorless nail polish and hair spray

The invention belongs to a chemical formula, according to which a completely non-toxic, odorless nail polish and hair gel can be produced, belonging to a cosmetic.

Nail polish, which is currently widely sold on the market, is an organic polymer such as nitrocellulose, polymeric acrylate (polyacrylic acid), alkyd resin, and the like; as ethyl acetate, trichloroethane, Butyl acetate, amyl acetate, toluene, as a solvent, plasticizer as a brightener, wherein the colorant contains lead chromate, cadmium yellow, and other toxic substances. Moreover, the organic solvent will volatilize into an odor. According to media reports, several nail painting workers, who died of cancer, are suspected to be related to the chemical composition of nail polish.

Once the nail polish is applied to the nail, if it is to be removed, it is necessary to use "Glass Water", which is similar to the "pine perfume" used by the painter to dissolve, causing secondary damage.

The invention uses sodium citrate, the molecular formula Na ₂ O. nSiO _{2 (aq)} (where n = 2, commonly known as No. 2 water glass) as an adhesive, using non-toxic colorants, such as titanium dioxide, ultramarine blue powder, yellow iron oxide, red iron oxide, black iron oxide, edible yellow, edible Red, edible green, edible purple, and the like are coloring agents. The above-mentioned color developing agents are mixed and ground with water glass to form red orange yellow green blue purple white black and white nail polish. Apply nails to the nails and apply them to the nails for about 2 minutes. If the customer feels dissatisfied after seeing the pattern, they can immediately wash them off with warm water. If the customer is satisfied, apply the cooking oil and the hardening reaction will occur. . The actual trial results are feasible, and the excess cooking oil provides a glossy effect. The reaction formula is as follows: sodium citrate + edible oil → sodium fatty acid + cerium oxide + glycerol Na ₂ O. nSiO _2(aq) +2RCOOR' _(l) +H ₂ O → 2RCOONa _(aq) +nSiO _2(s) +2R'OH _(l) But the nail polish is applied to the nail and has fine cracks after drying, which is commercialized. , is a disadvantage.

The above sodium citrate is changed to potassium citrate, and the molecular formula K ₂ O. nSiO _{2 (aq)} type n, commonly known as "modulo", try to find the highest available on the market, get n = 3.5 ~ 4.0, redo the above experiment, painted on the nail, the crack becomes very fine after drying, Very few. The reaction formula is as follows: potassium citrate + edible oil → fatty acid potassium + cerium oxide + glycerol K ₂ O. nSiO _2(aq) +2RCOOR' _(l) +H ₂ O → 2 RCOOK _(aq) +nSiO _2(s) +2 R'OH _(l)

The above potassium citrate will be changed to citric acid gum, and its molecular formula H ₂ O. When nSiO _{2 (aq) was} redoed for the above experiment, the crack completely disappeared. The reaction formula is as follows: citric acid gel + edible oil → fatty acid + cerium oxide + glycerol H ₂ O. nSiO _2(aq) +RCOOR' _(l) → RCOOH _(l) +nSiO _2(s) +R'OH _(l)

In the above experiment, the ruthenium soil was added to increase the viscosity, and the thickness of each application was increased.

Roll the hair on the styling equipment, brush the nail polish, and after drying it, brush the hardener and remove the styling equipment, then fix the hair.

(The invention is a chemical formula, so there is no pattern)

The RS-30 bismuth gel produced by the domestic manufacturer Rongxiang Chemical Co., Ltd. (a mixture of H ₂ Si ₂ O ₅ , H ₂ Si ₃ O ₇ , H ₂ Si ₂ O ₅ , H ₂ Si ₄ O ₉ The molecular formula is H ₂ O.nsiO _{2 ,} wherein the average value of n is about 3 to 4) 98 g and 2 g of bentonite are pre-ground, and then mixed with 20 g of titanium dioxide (commonly known as titanium dioxide) to become white nail polish, other color nails. The oil formula is as follows:

Take the above-mentioned nail polishes, draw on the customer's nails according to the pattern selected by the customer, and let the film dry after standing for 2 minutes. (If you encounter wet and cold weather, blow it with a hair dryer) and then show it to the customer. If the customer does not Satisfied, wash off with warm water, if the customer is satisfied, then let the customer choose the following cooking oil: salad oil, peanut oil, flax oil, olive oil, sunflower oil, lard, and On the nail, the edible oil and the citric acid gel react slowly, and after about 30 minutes, the water glass hardens into a water-insoluble cerium oxide film. The pattern on the nail is insoluble in water and the transaction is completed. After the customer returns, the pattern can last for about two weeks.

The hair is moistened with a customer-specified color of citric acid, and then wound on a styling equipment. After it is dried, the edible oil is used as a hardening agent to fix the hair. Finally, the styling equipment is removed, and the hair presents the shape and pattern desired by the customer.

On the skin specified by the customer, paint the customer-designed pattern with nail polish. After drying, apply the cooking oil as a hardening agent, and the pattern required by the customer will appear on the skin.
