Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to basic cosmetics in which a water-swelled sodium montmorillonite is used as a water base for oil dispersion in creams. This invention relates to the production of cream emulsions for basic cosmetics that do not use surfactants such as.

[Prior Art] The present inventor has been researching sodium montmorillonite and other clay minerals for many years and has continued to do so up to the present time. Among the sodium montmorillonite minerals, in particular, he has found a mineral with low iron content, high whiteness, and water swelling property. For example, those that have swollen 8 to 10 times or more and have high ion exchange ability have good thixotropic properties in areas controlled by slightly acidic conditions, making them excellent materials for basic cosmetics. It is known that it possesses the property.

In addition, the sodium montmorillonite water-swollen gel has excellent thin film-forming properties and is also compatible with various thickening agents, such as guar gum, which is a vegetable thickening agent, and is also compatible with polyvinyl alcohol, carboxymethyl cellulose, etc. Since it has compatibility with both, it can be fully expected to be used as a basic cosmetic material that requires a great skin cleansing effect.

[Problems to be Solved by the Invention] Based on this knowledge, the present invention provides sodium montmorillonite that is compatible with waste components such as amines, proteins, urea, lactic acid, histamine, etc. in the skin and absorbs them in combination. The object of the present invention is to provide basic cosmetics that use a water-swellable gel as a base for oil-dispersed water in creams.

[Means for Solving the Problems] The gist of the present invention is a basic cosmetic product that uses a water-swellable gel of sodium montmorillonite as an oil-dispersed water base for creams. It is intended to be able to be dispersed and to give good thixotropy and unique extensibility to the cosmetics, and the base contains animal fats and oils such as squalene, squalane, pristane, and mink, jojoba, avocado, Good results can be obtained by applying vegetable oils such as castor and olive oils, germ oils such as pearl barley, and oil-based vitamins such as vitamin E.

Furthermore, in the basic cosmetics according to the present invention, vegetable proteins extracted from soybeans, wheat, etc. are added as an oil emulsifying and dispersing agent in an amount of 0.2 to 4% by weight, preferably 0.5 to 2.5% by weight, based on the sodium montmorillonite water-swollen gel. Alternatively, higher fatty acid acyl esters of amino acids such as alginic acid and aspartic acid may also be used as emulsifying and dispersing agents.

In addition, the following formula compound of L-glutamine and natural fatty acid can also be applied to this.

These emulsifying and dispersing agents are more easily stabilized, and basic cosmetics with greater affinity for the skin can be obtained.

In the production of creams, anionic or nonionic activators have traditionally been used to disperse animal oils, vegetable oils, etc. in water, and in particular sorbitan ester or sorbitan ester ether type nonionic activators have been used. The amount is 3
5%, but these active agents permeate through the skin and enter the blood through the capillaries, which is not preferable since it may lower the surface tension of the blood.

The present invention makes it possible to produce creams by dispersing various oils in water instead of using these active agents.

That is, as an emulsifying and dispersing agent for oil, vegetable proteins such as soybean and wheat protein are more effective.
0.2-4%, preferably 0.5-2.5% of sodium-montmorillonite complex can be added.

In the present invention, as an emulsifying and dispersing agent for oil, vegetable protein such as soybean or wheat protein is used as an effective protein of 0.2 to 4%, preferably 0.5 to 2.5%.
It can be added as a composite of montmorillonite.

In addition, a complex of sodium montmorillonite of higher fatty acid acyl esters of amino acids such as alginic acid and aspartic acid can be used instead of conventional activators to enable emulsification and dispersion of oil.

Furthermore, the present invention provides fructose and glucose 30:70 or 70:30 (component ratio of various honeys)
5 to 10% of the mixture is added to impart emulsion stability, wettability, and moisture retention.

In addition, adding an extract extracted with water or oil from shikonin obtained by tissue culture or the purple root of the medicinal herb Murasaki is effective in eliminating sunburn and other inflammation.

Furthermore, the addition of an active ingredient extracted from the medicinal herb Otogilisa using an organic solvent such as ethyl alcohol or ethylene glycol is effective for extinguishing inflammation.
