Technical Field

[0001] The invention relates to the technical field of cosmetic compositions, in particular to a composition capable of adjusting the conductivity of skin care products and a preparation method thereof. Background Art

[0002] With the improvement of people's living standards, skin care has received more and more attention, and various skin care products have been widely used. Although skin care products contain various ingredients that are effective for the skin, only a part of them can be actively absorbed by the skin, and the absorption is slow.

[0003] In recent years, the development and promotion of home beauty equipment has won the favor of more and more people due to its excellent physical effects. In the contact between human body and skin care products and beauty equipment, electric current beauty equipment can effectively promote the penetration of nutrients of skin care products into the skin through the conduction of skin care products. In order to increase its care effect, it is often necessary to apply skin care products on the surface of the skin and the beauty equipment probe; this can promote the skin's absorption of nutrients and improve the care effect.

[0004] However, according to research experiments, the conductivity of most skin care products on the market is less than 1000μs / cm. If used directly with current beauty devices, it will increase the resistance of current penetrating the skin surface, which will affect the care effect of the beauty device.

[0005] Therefore, developing broad-spectrum highly conductive preparations that can improve the conductivity of skin care products and meet the requirements for use in current-type beauty devices is one of the important areas in the current skin care field.

[0006] Based on the diversity of skin care products on the market, the following conditions must be met to formulate a universal high-conductivity medium: 1) Biosafety, all ingredients must be green and safe raw materials; 2) Non-irritating to the skin, suitable for most skin types; 3) Compatible with existing skin care products, no biochemical reaction occurs, and no reduction in the efficacy of skin care products. According to the research, there is still a blank of related products on the market. Summary of the invention

[0008] According to an embodiment of the present application, the chloride salt is implemented as a mixture of potassium chloride and sodium chloride.

[0009] According to an embodiment of the present application, the chloride salt is a mixed solution of 0.2-0.7% sodium chloride and 0.02-0.4% potassium chloride.

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0020] The present invention provides a composition capable of improving the conductivity of skin care products, comprising the following components by weight percentage: Chloride 0.22~1.1%; Sodium alginate 0.05-0.8%; Citric acid 0.05~0.4%; Trisodium citrate 0.02~0.2%; Sodium succinate 0.01~0.4%; Disodium ethylenediaminetetraacetate 0.01~0.6%; Glycerin 1.0~10.0%; Diethylene glycol monoethyl ether 0.01~5%; The remaining ingredient is deionized water.

[0021] In a preferred embodiment, the chloride salt is a mixture of sodium chloride and potassium chloride. More preferably, the chloride salt is a mixture of 0.2-0.7% sodium chloride and 0.02-0.4% potassium chloride.

[0022] It is worth mentioning that the chloride salt component needs to be controlled at 0.22-1.1%. If the content is too high, although the conductivity of the final compound liquid can be improved, the osmotic pressure of the skin will cause the precipitation of water, which will cause excessive irritation to human skin, making the final compounded cosmetics fail to meet user requirements; if the content is too low, the conductivity of the compounded cosmetics cannot be effectively adjusted.

[0023] It is worth mentioning that the added sodium alginate and glycerol are used to increase the viscosity of the aqueous solution and act as moisturizers. The two can buffer the transmission of ions and reduce the irritation of the skin under the action of electric current.

[0024] It is worth mentioning that the added trisodium citrate and citric acid compound acts as a buffer, reducing the impact of acid-base changes on skin care products.

[0025] Preferably, the added sodium succinate and disodium edetate interact with the ions in the mixture to achieve a sustained release of ions, thereby reducing irritation of the ions to the skin; the mixture is particularly suitable for users with allergic skin.

[0026] As a preferred method, diethylene glycol monoethyl ether, as an organic nutrient component and a benign solvent, helps dissolve and disperse nutrients and promotes the skin's intake of nutrients. All raw materials have been used in various skin care products and have been proven to be green and safe reagents. At appropriate concentrations, they are non-irritating to the skin; at the same time, they are relatively stable in nature and will not react adversely with existing water-based skin care product ingredients, and can be evenly mixed with them to form a stable mixed solution.

[0027] After the complex is prepared, it is directly added to the regular skin care lotion in a certain proportion as a whole. It not only significantly improves the conductivity of the original skin care lotion and promotes its application in pulse current formula, but also promotes the skin's absorption of nutrients.

[0028] The conductivity of the composition prepared in the present application can be adjusted within the range of 5000 to 8000 μS / cm as the formula changes.

[0029] In addition, after the composition of the present application is compounded and fused with a conventional skin care liquid in a volume ratio of 1:5 to 5:1 (V complex / V skin care liquid) and fully mixed, the conductivity of the obtained new complex can be adjusted within 1200 - 6000 μS / cm.

[0030] The present application also provides a method for preparing a composition capable of adjusting the conductivity of skin care products, which includes the following steps: S1, adding deionized water with a mass percentage of 85 - 95%, 0.22 - 1.4% of chloride salt, 0.05 - 0.4% of citric acid, 0.05 - 0.8% of sodium alginate, 0.02 - 0.2% of trisodium citrate, 0.0 - 0.4% of sodium succinate, 0.0 - 0.6% of disodium ethylenediaminetetraacetate, 1.0 - 10.0% of glycerol, and 0 - 5% of diethylene glycol monoethyl ether; adding various salts and deionized water into a container equipped with a stirring device in a certain proportion successively, stirring until completely dissolved, then adding the above-mentioned predetermined amount of glycerol and diethylene glycol monoethyl ether, and continuing to stir until uniform to prepare the composition capable of adjusting the conductivity of skin care products.
