Abstract

PURPOSE:To prepare a beautifying cosmetic having activating action on bare skin and regenerating effects on the skin by dissolving an ultra-fine powdery eggshell in lactic acid, providing a creamy form and using the resultant creamy substance. CONSTITUTION:An eggshell which is a waste and having amino acids and a sticking collagen membrane is pulverized into ultra-fine powder having <=200 mesh size using a pulverizer such as a ball mill. An adequate amount of a lactic acid solution is then added to dissolve the fine powder and provide a creamy form. The resultant creamy substance is suitably blended with a wetting agent, an oil, a perfume, etc., and prepared into a cosmetic according to a conventional method to afford the objective beautifying cosmetic especially suitable as night cream, etc. The insoluble sticking collagen membrane is emulsified and dissolved to provide also a supply source for amino acids. The aforementioned cosmetic as a pure cream can be applied to bare skin for a long period and the abundantly contained amino acids are permeated thereby.

Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a method for producing beauty cosmetics using eggshell for the beauty of bare skin, face, etc. using ultrafine eggshell powder. It is.

``Conventional technology'' Traditionally, eggshells are in the form of a fine powder, and used as a raw material for directly reinforcing the lucium, mainly by extracting and dissolving the collagen membrane in a food additive or in a pot, and then producing a collagen-containing cream or using the organic components inside the shells. It is recovered in the form of amino acids using methods such as electrodialysis and used as amino acid-containing creams.

[Problem to be solved by the invention] When eggshell is used as a substitute for rhusium carbonate, and when it is ground into fine powder and used directly as a reinforcing agent, the characteristics of the attached collagen membrane and the amino acids it contains cannot be fully utilized. . Moreover, in order to increase added value, various chemical methods are required to separate and utilize these, which is economically disadvantageous.

The present invention solves the above-mentioned drawbacks and relates to the production of beauty cosmetics that take advantage of the properties of all the ingredients of eggshell.

``Means for solving the problem'' Eggshells that have been made into ultrafine powder (200 mesh or less) can be dissolved by adding an appropriate amount of lactic acid solution to both the shell containing amino acids, which is the main component, and the attached collagen membrane. It becomes a creamy homogeneous product at room temperature.

By pulverizing eggshells into ultra-fine powder for a relatively long period of time using a grinder such as a regular ball mill, beauty cosmetics with a high amino acid content can be obtained by making use of all the eggshells.

In order to increase the added value of beauty cosmetics, it is necessary to use conventionally known humectants such as propylene glycol,
Oil agents such as liquid paraffin, fragrances, etc. can be added. A method for producing beauty cosmetics using ultrafine powdered eggshell, which consists of the above production method.

``Effect'' In eggshells with a particle size of about 200 mesh or more, the attached collagen membrane is insoluble in lactic acid, but when it is made into an ultrafine powder of less than 200 mesh, it gradually emulsifies and dissolves. It is thought that this is because the polymeric collagen film, which has grown into fibers, is mechanically cut and becomes relatively single fibers during the frictional process.

Beauty cosmetics using ultra-fine powdered eggshells have a high content of around 10 parts, a total of around 7% amino acids present as organic substances within the shells and around 3% amino acids resulting from emulsification and decomposition of the collagen membrane. These ingredients promote the activation of bare skin and skin regeneration effects.Also, lactic acid and lactic acid lucium have been shown to have bactericidal effects on certain types of bacteria, and are expected to have medicinal effects.

"Example" One aspect of the present invention will be explained below.

1st Step: After washing the eggshell with water and drying, it is made into ultrafine powder particles of 200 mesh or less using a ball mill or the like.

Put 3.5kg of eggshell raw material into a mill with an internal volume of 5dm, and each eggshell has a diameter of 2.5-3.5cm and a weight of 3.
When 35 balls weighing 5-55g are put in and crushed at a speed of 60 revolutions per minute for about 40 hours, it becomes a powder that does not resist when crushed with fingers, and the grain size is less than 200 mesh. becomes.

2nd step Add appropriate amounts of lactic acid and water to the ultra-fine powdered eggshells above at room temperature, stir well until the bubbles disappear, then leave for about 40-50 minutes and stir again when the whole starts to become creamy. to make it uniform. The standard mixing ratio is as follows.

Ultrafine powdered eggshell 10 parts Lactic acid 18 parts Pure water 100 parts 3rd step While stirring the solution that is becoming creamy after the 2nd step, add polyhydric alcohols such as propylene glycol as a wetting agent and liquid paraffin or other oils as an oil agent. Higher fatty acids, esters, potassium hydroxide as a neutralizing agent, polyoxyethylene (20) sorbitan monostearate as a surfactant, and other ingredients such as fragrances and preservatives are blended. The standard mixing ratio is as follows.

Propylene glycol 20 parts Liquid paraffin 20 parts Potassium hydroxide 0.2 parts Polyoxyethylene (20) Sorbitan monostearate 3s 4th step Add a suitable amount of vanishing cream prepared according to the usual recipe to the product that has gone through the 3rd step. By adding this amount, it is possible to enhance the tactile properties such as smoothness on the bare skin when using the present beauty cosmetic, and to ensure appropriate fluidity.

The blending ratio of the Vanishing Cream to be prepared is as follows.

Stearic acid 8 parts Stearyl alcohol 6 parts Butyl stearate 8 parts Glycerin monostearate 2 parts P-paraben 0.5 parts The aqueous layers are each heated to 75-90°C and then thoroughly stirred to emulsify and form a homogeneous cream.

Fifth step After preparing the cosmetic composition of the present invention, when it starts to become creamy, add vanishing cream and stir well to obtain a uniform state. The standard mixing ratio is as follows.

Cosmetic composition of the present invention: 80-90 parts Vanishing cream: 10-20 parts "Effects of the invention" Eggshells are mass-produced by increasing the efficiency of poultry farms. On the other hand, a large amount of food is discarded as food waste in the confectionery manufacturing industry, but its use is only being used by a few large companies. In addition, it is believed that the current usage method does not take full advantage of the characteristics of eggshells.The present invention was invented as a more effective method of using eggshells after careful consideration of the characteristics of these wastes. 6 When eggshells are dissolved in lactic acid under normal conditions, the attached collagen films remain insoluble and dispersed in the product, and these can be utilized as so-called scrub particles when used as cosmetic creams.

However, with scrub facial cleansers, it is not possible to apply them to bare skin and keep them for a long time due to the presence of insoluble scrub particles, so it is not a daily practice for going out, etc. Must be peeled. However, in the beauty cosmetics using the ultrafine powdered eggshell of the present invention, the insoluble attached collagen film is emulsified and dissolved, and it also serves as a source of amino acids, so it can be applied to bare skin as a pure cream for a long time. Therefore, it is expected that the abundant amino acids contained therein will penetrate, and it is considered to have a high activity or regeneration effect on the skin, making it particularly suitable for night creams.
