Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bath composition. More specifically, the present invention relates to a bath composition containing macadamia oil and dairy products as active ingredients.

(B) Conventional Technology In recent years, interest in bath agents has increased, and many proposals for bath agents have been made with particular attention to beauty and health. The bath agent is generally a mixture of inorganic salts such as mirabilite, borax, sulfur, salt and carbonate with a fragrance, a coloring agent, a plant extract, an organic acid and the like, and the action and effect thereof may vary depending on the ingredients. To improve blood circulation and increase metabolism,
It has an effect of promoting sweating action to eliminate waste products of the body and keeping the body warm for a long time by covering the skin with salts. In addition to this, it is said to have a skin cleansing effect, a therapeutic effect against various diseases such as skin diseases, a moisturizing effect to moisturize and smooth the skin, and a psychological effect due to color and scent.

The milk bath, which is considered to be a type of bath agent, has long been said to be good for beauty. Actually, the active ingredient in milk brings about a skin-beautifying effect. As a related art related to this, for example, milk ingredients (milk, milk powder, unsweetened condensed milk, fresh cream, etc.) are included in cyclodextrin. As a result, a bath agent having improved storage stability of the milk component has been proposed (JP-A-60-181013).

Further, regarding the use of macadamia oil, a proposal utilizing it as a component of cosmetics is known (JP-A-58-177908,
JP-A-59-21609, JP-A-59-27808). However,
None of the above-mentioned conventional proposals describes or suggests the use of a bath agent for macadamia oil.

Macadamia oil is used in macadamia nuts.
NIFOLIAF.MUELL) is a liquid vegetable oil. And the oil has a fatty acid composition similar to human sebum (palmitic acid, palmitooleic acid, oleic acid, etc.), has a light feel and an excellent affinity, compared to general vegetable oils and fats,
It is known to have an extremely light feel and excellent affinity and spreadability.

(C) Problems to be Solved by the Invention In the above-mentioned conventional proposal of a bath preparation containing a clathrate compound in which the above-mentioned milk components (milk, powdered milk, sugar-free condensed milk, fresh cream, etc.) are clathrated with cyclodextrin, The milk component used here has been improved in terms of storability as compared with the milk component not included in cyclodextrin, but it is still not sufficient.

It is known that milk fat contained in the above-mentioned milk component is hydrolyzed by lipase to produce fatty acids such as butyric acid, which causes rancid odor. In addition, the phospholipids in the above milk components are oxidized by various factors such as temperature, acidity, light, bacteria, and the presence of a trace amount of metal to form various carbonyl compounds, which cause an oxidative odor. It is also known. Furthermore, it is also known that an offensive odor such as an acid odor, a heating odor, and a fish odor is expressed due to various factors.

Thus, the milk fat in the milk components (milk, powdered milk, sugar-free condensed milk, fresh cream, etc.) is extremely unstable, and when the above-mentioned conventionally proposed bath agent was actually used, it was used for inclusion. The cyclodextrin dissolves in hot water and the milk components are directly exposed to hot water in the bath resulting in accelerated oxidation. The bathtub is in a very favorable condition for the change of the milk component, and the milk fats, which are originally effective for the skin, are deteriorated, and troubles such as acrid rancidity are caused.

As described above, in the proposal, although the storability during storage is improved, there is a difficulty in avoiding the above-mentioned troubles in actual use.

(D) Means for Solving the Problems In light of the above circumstances, the present inventors have focused on a milk bath that has long been known to have excellent effects on health and beauty, and found that it is stable and healthy. We have earnestly conducted research on a new type of bath composition that also has beauty.

As a result, they have discovered a new type of bath agent composition that avoids the above-mentioned troubles and has a stable and extremely excellent effect on health and beauty that has never been proposed.

Accordingly, the object of the present invention is to have a stable dairy product with the removal or reduction of milk fat that causes the above-mentioned troubles and a fatty acid composition similar to human skin oil, and to a marked extent compared to general vegetable oils and fats. By using macadamia nut oil, which has excellent oxidative stability, as an active ingredient, it supplements the removed or reduced milk fat, and in addition to the advantages of macadamia oil, the active ingredients of dairy products work together and stabilize. Another object of the present invention is to provide a new type of bath agent composition having both health promotion and beauty effects.

The bath agent composition of the present invention is characterized by containing a dairy product and macadamia nut oil as active ingredients, and if desired, further mixed with other known bath agent raw materials.

The macadamia nut oil used in the present invention is a subtropical fruit tree (MACA
DEMIA TERNIFOLIAF.MUELL) is a liquid vegetable oil obtained from nuts.

Macadamia nut oil is readily available on the market and does not require any particular quality, but preferably refined macadamia nut oil is more colorless and odorless,
In addition, the content of palmitooleic acid, which is the same as human skin oil, is high,
It is also more suitable for use because it has excellent oxidative stability.

Further, as the dairy product used in the present invention, any one can be used as long as milk fat is removed or reduced, for example, skim milk, skim concentrated milk, skim milk powder, whey powder,
Examples thereof include casein sodium and casein enzyme decomposition products.

The effect can be further enhanced by mixing other known bath material with the bath composition containing the dairy product and macadamia nut oil of the present invention as active ingredients. Examples of such bath material include sodium chloride, sodium hydrogen carbonate, sodium carbonate, sodium sulfate, sodium thiosulfate, calcium carbonate, magnesium carbonate,
Inorganic salts such as potassium sulfide, potassium bromide, calcium oxide, aluminum sulfate, iron sulfate; inorganic acids such as boric acid, silicic acid anhydride, metasilicic acid; for example, benzoic acid, citric acid, fumaric acid, tartaric acid, pyrrolidone Organic acid salts such as carboxylic acids; for example, fragrant scented peach, yellow oak, chamomile, cinnamon bark, toki, mint, iris, peony, orange peel (Spruce), ten medicines (juyaku), sansho (sansho), dragon brain (ryuno)
Crude oils such as; oils and fats such as olive oil, soybean oil, nuka oil, liquid paraffin; alcohols such as ethanol, stearyl alcohol, isopropyl alcohol, cetyl alcohol; many such as glycerin, propylene glycol, sorbitol Examples of the polyhydric alcohols: known synthetic fragrances, natural fragrances, known pigments, and others, for example, sulfur, mineral sand, sodium salicylate, vitamins, egg yolk powder, polyvinylpyrrolidone, carboxymethylcellulose sodium, etc. it can.

The above-mentioned bath raw materials may be appropriately selected and used according to the purpose of the bath, and the form thereof is not particularly limited, and examples thereof include powders, granules, tablets, pastes, herbal medicines, and extracts or appropriately shredded. You can use the one in the ready state. Further, the amount of these bath raw materials to be used can be appropriately selected depending on the purpose of use.

The bath composition of the present invention is, for example, a powder type, a granule type, a liquid type (transparent or emulsion) depending on the purpose.
Can be prepared in various dosage forms such as.

The amounts of dairy products and macadamia nut oils used in the bath composition of the present invention can be appropriately selected and used without particular limitation, but in the case of dairy products, for example, a bath The range of about 0.01 to about 50% can be exemplified with respect to the agent composition. In the case of macadamia nut oil, for example, about 0.01 to about 50% based on the bath composition.
The range can be increased.

In order to produce the bath composition of the present invention, powder type, granule type, liquid type or macadamia nut oil used above, dairy products, and other types of bath agent raw materials are different, Can be easily manufactured by simply selecting and mixing the above-mentioned raw materials suitable for powder or liquid type. Further, the above-mentioned raw materials can be prepared in various dosage forms in advance and then mixed to prepare the bath agent composition of the present invention.

Thus, the bath composition of the present invention has, in addition to the health and beauty effects that milk originally has, a fatty acid composition similar to human skin oil of macadamia nut oil and an extremely light feel and excellent affinity compared to general natural oils and fats. Spreadability can further contribute to health and beauty effects.
