Description

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

(b) Prior Art In recent years, interest in bath additives has increased, and many proposals have been made for bath additives that are particularly focused on beauty and health. Bath preparations are
Generally, it is a mixture of inorganic salts such as mirabilite, silt, sulfur, salt, carbonate, etc., combined with fragrances, colorants, plant extracts, organic acids, etc., and its actions and effects vary depending on the ingredients, but it improves blood circulation. It has the effect of improving metabolism and increasing metabolism, promoting sweating to eliminate waste products from the body, and keeping the body warm for a long time by coating the skin with salts. In addition, it is said to have a skin cleaning effect, a therapeutic effect on various diseases including skin dandruff disease, a moisturizing effect that makes the skin moist and smooth, and a psychological effect due to its color and scent.

Milk baths, which are considered a type of bath additive, have long been said to be good for beauty. In fact, the active ingredients in milk have a beautifying effect on the skin, and conventional techniques related to this include, for example, the inclusion of milk ingredients (milk, powdered milk, evaporated milk, fresh cream, etc.) with cyclodextrin. Therefore, a bath additive with improved storage stability of the milk component has been proposed (Japanese Patent Application Laid-Open No. 60-181013).

Regarding the use of macadamia oil, there is a known proposal to use it as an ingredient in cosmetics (Japanese Patent Laid-Open No. 58-1779).
08, JP 59-21609, JP 59-2780
8). However, the above-mentioned conventional proposals neither describe nor suggest the use of macadamia oil as a bath additive.

Macadamia oil is made from macadamia nuts (MA CADEM).
It is a liquid vegetable oil obtained from IA TERNIFOLIAF, MUELL). Crude oil has a fatty acid composition similar to human sebum (palmitic acid, palmitoleic acid, oleic acid, etc.), has a light feel and excellent affinity, and is extremely light compared to general vegetable oils. It is known to have excellent texture, affinity and spreadability.

(C) Problems to be solved by the invention Milk ingredients mentioned above (milk, powdered milk, evaporated milk, fresh cream, etc.)
In the above-mentioned conventional proposal of a bath agent containing an clathrate compound clathrated with cyclodextrin, the milk ingredient used here has not been improved in terms of storage stability compared to a milk ingredient not clathrated with cyclodextrin. However, it is still far from sufficient.

Milk fat contained in the above-mentioned milk components is hydrolyzed by lipase to produce fatty acids such as butyric acid,
It is known to cause rancid odor. In addition, the phospholipids in the milk components mentioned above undergo oxidation due to various factors such as temperature, acidity, light, bacteria, and the presence of trace amounts of metals, producing various carbonyl compounds, which cause oxidized odor. It is also known that Furthermore, it is known that various factors can cause malodors such as acid odor, heating odor, and fish odor.

As described above, the milk fat in the milk components (milk, powdered milk, evaporated milk, fresh cream, etc.) is extremely unstable, and when the conventionally proposed bath additives mentioned above are actually used, Cyclodextrin dissolves in hot water, and milk components are directly exposed to hot water in the bathtub, resulting in accelerated oxidation. A bathtub is an extremely favorable condition for the milk components to change, causing troubles such as deterioration of the milk fat, which is originally effective for the skin, and development of a rancid odor.

As mentioned above, in this proposal, although the preservability during storage has been improved, there are problems in actual use that make it difficult to avoid the above-mentioned troubles.

(d) Means for Solving the Problems In view of the above circumstances, the present inventors focused on milk bath, which has been known for a long time to have excellent effects on health and beauty. We have been conducting intensive research on a new type of bath additive composition that has both beauty benefits.

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

Therefore, the object of the present invention is to provide a stable dairy product with a fatty acid composition similar to human sebum, which is free of or reduces the milk fat that causes the above-mentioned problems, and which is significantly superior to general vegetable oils. By using macadamia nut oil, which has excellent oxidation stability, as an active ingredient, it supplements the removed or reduced milk fat, and in addition to the benefits of macadamia oil, the active ingredients of dairy products work together to provide stability. To provide a new type of bath salt composition that has both health promotion and beauty effects.

The bath agent composition of the present invention is characterized in that it contains dairy products and macadamia nut oil as active ingredients, and is further mixed with other known bath agent raw materials if desired.

Macadamia nut oil used in the present invention is a subtropical fruit tree (MAC) belonging to the Proteaceae family native to Australia.
ADEMIA TERNIFOLIAF, MUELL
) is a liquid vegetable oil obtained from the nuts of the tree.

Macadamia nut oil is easily available in the market,
Although it does not require special quality, it is preferable to use refined macadamia nut oil, which is almost colorless and odorless, has a high content of palmitooleic acid, which is the same as human sebum, and has good oxidation stability. It's so good that I use -q4.

In addition, as the dairy products used in the present invention, any product with milk fat removed or reduced can be used, such as skim milk, skim concentrated milk, skim milk powder, whey powder, sodium caseinate, and casein enzyme decomposition. Examples include things.

By mixing other known bath agent raw materials into the bath agent composition containing the dairy product and macadamia nut oil of the present invention as active ingredients, a layer effect can be achieved. Such bath agent raw materials include, for example, sodium chloride, sodium hydrogen carbonate, sodium carbonate, sodium sulfate, sodium thiosulfate, calcium carbonate, magnesium carbonate, potassium sulfide, potassium bromide, calcium oxide, aluminum sulfate, and iron acid. Inorganic salts; for example, boric acid,

, Yellow oak), Chamomile, Cinnamon bark, Touki, Hatsuka, Calamus, Peony, Seed coat (Spruce), Juyaku (Juyaku)
Herbal medicines such as , Sansho, and Dennou; For example, oils and fats such as olive oil, soybean oil, bran oil, and liquid paraffin; For example, ethanol, stearyl alcohol, isopropyl alcohol, cetyl alcohol, etc. Alcohols; Polyhydric alcohols such as glycerin, propylene glycol, and sorbitol; Known synthetic fragrances and natural fragrances; Known pigments; Other examples include sulfur, mineral sand, sodium salicylate, vitamins, egg yolk powder, Examples include polyvinylpyrrolone, sodium carboxymethyl cellulose, and the like.

The above-mentioned raw materials for bath additives may be selected and used as appropriate depending on the purpose of the bath additive, and there are no particular restrictions on their form, such as powder, granules, tablets, paste, extracts for crude drugs, or appropriately chopped You can use the one in the condition. Moreover, the amount of these bath agent raw materials to be used can be appropriately selected depending on the purpose of use.

The bath agent composition of the present invention can be prepared into various dosage forms such as powder type, granule type, and liquid type (transparent, emulsion) depending on the purpose.

The amounts of dairy products and macadamia nut oil used in the bath agent composition of the present invention are not particularly limited and can be appropriately selected and used; however, in the case of dairy products, for example, An example range is about 0.01 to about 50% based on the bath agent composition. In addition, in the case of macadamia nut oil, for example, about 0.01
The range is approximately 50%.

To produce the bath agent composition of the present invention, powder type,
It depends on the type and form of macadamia nut oil, dairy products, and other bath additive ingredients used, such as granule type, liquid type, or the above-mentioned ingredients, but in general, the above-mentioned ingredients suitable for powder or liquid type are selected. It can be easily manufactured by simply mixing. Alternatively, the bath agent composition of the present invention can be prepared by preparing the above-mentioned raw materials in advance into various dosage forms and then mixing them.
