Description

[Detailed description of the invention] <Industrial application field> The present invention relates to bath preparations with excellent cosmetic effects.

<Conventional technology> Conventional bath additives include concentrated hot spring water, mixtures of various chemical bath additive ingredients such as sodium carbonate and sodium hydrochloride, and beverages such as alcohol and milk. is known, and its efficacy is as follows:
It is well known for its effects on recovery from fatigue, reduction of pain sensations such as stiff shoulders and lower back pain, healing of wounds and diseases, and beauty effects.

<M's that the invention seeks to solve> However, conventional bath additives made from concentrated hot spring water can only be produced in specific areas, are therefore expensive, and are difficult to use every day. Bath additives containing chemical bath additives are easily available, but they lack beauty effects.

Furthermore, since the amount of drinks such as alcohol and milk used is significantly larger than that of other bath additives, they are expensive and difficult to use on a regular basis.

As mentioned above, bath additives that are said to have excellent beauty effects are difficult to obtain and use regularly, and bath additives that are easily available currently lack beauty effects.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a bath additive that has excellent cosmetic effects, is inexpensive, and can be used every day.

Means for Solving the Problems> The bath layer agent according to the present invention for achieving the above object is characterized by containing eggshell membrane.

In the present invention, the eggshell membrane refers to the membrane that exists inside the eggshell of the egg of a bird such as a chicken, quail, or duck. It also includes powdered eggshell membranes obtained by collapsing and pulverizing eggshell membranes, and soluble eggshell membranes obtained by chemically treating eggshell membranes. Here, soluble eggshell membranes refer to eggshell membranes that are dissolved in water by being decomposed by the action of acid/alkaline agents, redox agents, oxygen, etc.

In addition, in the present invention, bath additives refer to substances added to the bath during bathing, and the active ingredients contained in these substances promote blood circulation, provide stimulation, or provide mental stability to the body, resulting in recovery from fatigue. , which exhibits effects such as stress relief, reduction of physical pain, healing of wounds and diseases, and beauty effects.

In the bath agent of the present invention, the eggshell membrane contains an unknown active ingredient that exerts a cosmetic effect, and can be used as a single product as a bath agent. , sodium bicarbonate, sodium chloride, sodium sulfate, borax, etc.), fragrances, pigments, excipients, etc., to form a bath agent.

Therefore, in the present invention, the term "containing" eggshell membranes applies not only to cases in which 100% (by weight) eggshell membranes are contained, but also to cases in which eggshell membranes are contained in a portion of the bath additive. The blending ratio of eggshell membranes can be set arbitrarily depending on the intended use in the bath additive. In addition, when the bath agent is in liquid form, "containing" includes those in which eggshell membranes are dissolved in the liquid.

Typical formulation examples include: a) The above-mentioned general bath agent raw materials (sodium a, sodium hydrogen carbonate, etc.) 99-9
5% b) Eggshell M1-5% C) Flavoring agent Appropriate amount can be given.

Next, an example of a method for producing eggshell membranes and decomposed eggshell membranes used in the present invention will be shown.

(2) Method for Obtaining Eggshell Membranes The eggs with shells may be broken and the egg liquid removed from the eggshells, and then dried as appropriate) to obtain eggshell membranes.

(2) Method for Obtaining Powdered Eggshell Membranes After drying the eggshell membranes obtained in (2), they are crushed by a conventional method to obtain a powder with a particle size of about 0.01 to 100 μm, and this powder is used as a bath additive.

The particles obtained by this method have the advantage that if they have a particle size within this range, they will not easily settle when dispersed in a bath, and the production cost will be low.

■ Method for obtaining soluble eggshell membranes Soluble eggshell membranes obtained by decomposing eggshell membranes separated from eggshells with acids, alkalis, enzymes, etc. can also be used as bath additives. Eggshell membranes are added to a solution containing an alkaline agent and an organic solvent such as methanol or ethanol in a ratio of 20:80 to 90:10 (alkali concentration: 02 to 3, about ON) and heated at 30 to 60°C for 3 to 8 hours. Upon treatment, a solution of eggshell membranes is obtained, and this solution is filtered and dried if necessary in an oven to obtain powdery, odorless, white, soluble eggshell membranes.

The eggshell membranes, powdered eggshell membranes, and soluble eggshell membranes obtained as described above may be used as bath additives as they are; It can also be used as a bath additive by adding sand, etc.

The bath additive of the present invention can be made into any desired form, such as liquid, powder, or granule.

Further, it may be used by enclosing it in a paper or cloth bag or net, if necessary.

The bath additive of the present invention has eggshell membranes in the bath water of Q,
001ppm~101000pp per bath water II 0.0
01 to 1000 g).

When the bath preparation of the present invention obtained as described above is used, excellent cosmetic effects are exhibited as shown in the test examples below.

In addition, the eggshell membrane used in the present invention is currently discarded without being used together with the eggshell, but it can be easily and inexpensively produced from eggshell membranes at large-scale egg breaking farms. Therefore, the bath additive of the present invention can be produced at low cost by using the eggshell membrane of Otsu.

Effect> When using the bath preparation containing the eggshell membrane of the present invention, it is thought that the unknown active ingredient contained in the eggshell membrane activates epidermal cells and fibroblasts to produce a cosmetic effect.

Examples (1) Adjustment of soluble eggshell membrane After cracking chicken eggs with shells and removing the egg fluid, the resulting eggshells with eggshell membranes are placed in clean water, and the eggshells are manually removed. Eggshell membranes were obtained. Next, the obtained eggshell membranes were immersed in a 1% aqueous hydrochloric acid solution for 1 hour to dissolve minute eggshells adhering to the eggshell membranes, washed with water, and dried in the sun to obtain dried eggshell membranes.

Dried eggshells obtained in this way! 1100 g of 2N sodium hydroxide aqueous solution 1200 mj and absolute ethanol 8
00 mj was added and treated at 40° C. for 5 hours with stirring to solubilize the eggshell membranes.

Next, the obtained liquid was filtered through a cloth filter, neutralized and desalted, and then freeze-dried to obtain 53 g of powdered soluble eggshell membrane.
