Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a bath agent containing chitin as an active ingredient.

[Prior Art/Problems] Bath preparations are external preparations, and as a general rule, they are used by being poured into a bathtub. Effective for heat rash, rough skin, stiff shoulders, neuralgia, chilblains,
Examples include sensitivity to cold and recovery from fatigue.

Conventionally used bath additives include sulfur agents,
They were mainly formulated with alkaline agents such as soda carbonate, soda carbonate, and sodium tripolyphosphate as a base. Examples of its formulation are described below.

Mixing example () (parts by weight) Sodium polyphosphate 5 Sekis Sodium Carbonate 20 Borax 5 Blue No. 2 0.1 Fragrance 0.1 Add purified water to make 100 parts by weight.

Combination example () Sulfur or Yunohana 2 Neutral white clay 10 Benzoic acid 0.2 Uranin Conf 0.1 Fragrance 0.1 Add purified water to make 100 parts by weight.

Compounds such as those described above are approved for use in the form of powders, granules, tablets, soft capsules, liquids, and the like.

However, almost all conventional bath additives are alkaline and cannot be used on infants because they are too irritating and can damage the skin. Additionally, if swallowed, there is a problem of toxicity, and furthermore, the medicinal effects were not as high as expected.

Therefore, an object of the present invention is to provide a bath additive that is harmless to the human body and has the same or better efficacy than conventional products.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present inventors have conducted intensive research and found that bath preparations containing chitin as an active ingredient are effective, and in order to complete the present invention. I've reached it.

That is, the present invention resides in a bath agent characterized by containing chitin.

[Action] The shells of crustaceans such as crabs and shrimps and the outer skins of arthropods contain a substance called chitin that forms a complex with protein and calcium carbonate. Chitosan is obtained by hydrolyzing chitin. Chitosan is a linear polysaccharide in which 2-amino-2-dioxy-D-glucol (D-glucosamine) is linked with β-(1→4) bonds. Chitin and chitosan have almost no toxicity concerns for humans and animals, are highly biocompatible, and are biodegradable.They are used in medicine and the medical field, such as candy, wound treatment agents, wound dressings after skin abrasion, and surgical threads. It is a substance for which applied research is actively being conducted.

As mentioned above, chitin is a substance that is being used in the medical and pharmaceutical fields, and is highly safe.If chitin is used as an active ingredient in bath additives, it will be harmless to the human body and will be as effective as or better than conventional products. A bath agent with efficacy can be provided.

Note that chitin is soluble in inorganic acids, organic acids, solvents, etc., and can be blended as solutions of these.

In the bath preparation of the present invention, as an active ingredient,
It should be understood that as long as it contains 0.1 to 30% by weight of chitin and can be used as a bath additive, it is possible to provide a bath additive that is harmless to the human body and exhibits excellent efficacy.

Furthermore, the pigments and fragrances to be used in combination with chitin are not particularly limited, and commonly used ones can be used.

The bath agent of the present invention can be used by dissolving 1 g of the bath agent in a bathtub at a ratio of about 10 to 100, and various effects can be obtained.

[Example] The present invention will be further explained with reference to Examples below.

Example 1 Sodium bicarbonate 55% by weight Sodium tripolyphosphate 33% by weight Sodium chloride 3% by weight Carboxymethyl chitin 1% by weight Disodium ethylenediaminetetraacetate 2% by weight Egg yolk powder 6% by weight Fragrance Trace amount 20 people randomly selected Bath additives with the above formulation
25g was dissolved in about 300 baths.
The results are described below.

Rough skin: No rough skin. My heat rash and chilblains have healed.

Skin feel: Smooth, smooth and shiny.

Looseness: The water never gets cold and stays warm forever.

Nocturnal enuresis: The child's nocturnal enuresis has been cured.

Fatigue recovery: Faster recovery from fatigue.

Ringworm and athlete's foot: cured after 3 to 5 days of continuous use.

Example 2 Carboxymethyl chitin 0.5% by weight Citric acid 5% by weight Propylene glycol 3% by weight Uraninkov pigment 0.1% by weight Fragrance Slightly purified water Balance A bath agent having the above formulation was used in the same proportion as in Example 1. , similar results were obtained.

[Effects of the Invention] The bath agent of the present invention has medicinal effects that have not been observed in conventional bath agents, such as preventing skin roughness, roughness, heat rash, chapped skin, acne, etc., tightening the skin,
It has effects such as cleaning. It can also moisturize and protect the skin, preventing it from drying out, and can also prevent body odor and sweat odor.

Furthermore, when the bath preparation of the present invention is used as a hair rinse, it is expected to have effects such as preventing dandruff and itchiness, making hair supple, and preventing the generation of static electricity.
