Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a bath-side composition, particularly a bath-side composition that provides moisturization to the skin after bathing, is not sticky, and does not deteriorate in quality even after long-term storage. The present invention relates to a composition.

[Prior art]

Conventionally used bath-side compositions are mainly composed of a mixture of inorganic salts such as sodium to lithium sulfate, sodium to lithium chloride, borax, and alkali carbonate as bath agent components, and contain oil, fragrance, and coloring. It is a mixture of auxiliary ingredients such as water, which gives scent and color to the bath water, makes you feel more comfortable while bathing, promotes blood circulation, activates metabolism, and has effects on cold sensitivity, recovery from fatigue, etc. and is widely used in general. However, conventional commercially available bath compositions are mainly aimed at making you feel more comfortable while taking a bath and relieving fatigue. At present, little consideration is given to so-called skin care effects.

〔the purpose〕

An object of the present invention is to provide a bath-side composition that has skin care effects that are appreciated by users, unlike conventional bath-side compositions.

〔composition〕

According to the present invention, in a bath side composition containing a granular bath agent component, the composition contains an encapsulated substance containing one or more compounds selected from terpene hydrocarbons as a core substance. A bath agent composition is provided.

The bath agent composition of the present invention is characterized by containing an encapsulated material containing one or more compounds selected from terpene hydrocarbons as a core material. Terpene hydrocarbons are chain or cyclic compounds represented by (C10HI6)n, most of which are present in plants, form the main component of essential oils, and are volatile and aromatic. In the case of the present invention, it is preferable to use monoterpene hydrocarbons (n=1), such as those that are liquid at room temperature such as pinene, limonene, myrcene, and sabinene. Such terpene hydrocarbons may be used alone or in the form of a mixture of two or more.

In the present invention, the terpene hydrocarbon is used as an encapsulated product, and the encapsulated product in this case is
It can be produced according to conventionally known methods, and exhibits dissolution or disintegration properties upon use.

That is, the encapsulated terpene hydrocarbon used in the present invention is used by being put into bath water, and is subjected to the dissolving power and heating by the bath water, but in the case of the present invention, the capsule containing the terpene hydrocarbon is The terpene hydrocarbons contained in the capsules are released into the bath water by being dissolved by the dissolving power of the bath water, or disintegrated by the increase in internal pressure due to evaporation of the terpene hydrocarbons caused by heating with hot water.

In the encapsulated product containing a terpene hydrocarbon used in the present invention, the material forming the capsule can be various conventionally known materials, including water-soluble polymers as shown below.

(1) Protein; for example, gelatin, etc.

(2) Polysaccharides; for example, pectin, carrageenan, alginic acid, glucan, guar gum, etc.

(3) Cellulose derivatives; for example, carboxymethyl cellulose, hydroxyethyl cellulose, etc.

(4) Other water-soluble polymers; for example, polyvinyl 3- Alcohol, polyacrylic acid, poly Ethoxy ether etc.

When such a capsule made of a water-soluble polymer is placed in bath water, it dissolves in the bath water, and the terpene hydrocarbons contained therein are released into the bath water. In the case of the present invention, among the capsules made of the water-soluble polymer, gelatin capsules are preferred from the viewpoint of ease of availability and ease of manufacturing encapsulated terpene hydrocarbons.

Furthermore, in the present invention, as the capsule material, in addition to the above-mentioned water-soluble polymers, hydrophobic polymers can also be used, and for example, polystyrene, polyvinyl ester, polyvinyl ether, polypropylene, polyethylene, etc. can be used. .

Capsules made of such hydrophobic polymers, unlike the water-soluble capsules mentioned above, do not show solubility in bath water;
When placed in bath water, the encapsulated terpene hydrocarbons are heated and evaporated by the hot water, creating pressure inside the capsule, which causes the capsule to collapse and the terpene hydrocarbons inside to be released. As shown in the figure, the thickness of the capsule was partially reduced.

In the encapsulated material used in the present invention, the capsule diameter is not particularly limited, and the capsule diameter (diameter) may be, for example, 0.
．． In addition to being able to make it as large as 2 to 5 ml,
It can also be made into microcapsules with a capsule diameter of less than 0.2+nm. The polymer forming the capsule wall may be used in a proportion that is not easily destroyed by storage impact, and the amount is not particularly limited, but generally the ratio of the content to the polymer is 575. - 9/1, preferably about 7/3 - 8/2, and in the case of items that show disintegration when placed in hot water, 7/3 - 9/1, preferably 8/2
It is best to set it to about 2 to 9/1.

When obtaining the encapsulated product used in the present invention, the capsule diameter is 0.
．． In the case of 2 to 5 m long, in general, a sheath made of liquid polymer is extruded from a double nozzle so as to surround the liquid terpene hydrocarbon used as the core material, and then it is made into droplets. It can be obtained by solidifying the polymer that forms the capsule (Japanese Patent Application Laid-Open No. 47-391
Publication No. 11). In addition, capsules with a diameter of 0.2 m or less can be manufactured by the above-mentioned double nozzle method, as well as by ordinary microencapsulation methods such as coacervation method.
Organic phase separation method. It can be obtained by a polymerization method or the like.

The contents of the encapsulated product used in the present invention contain terpene hydrocarbons as an essential component, but can also contain essential oils and oils as auxiliary components for bath use, if necessary. In this case, the essential oils include, for example, peppermint oil, jasmine, artificial jam incense, camphor, calamus oil, cypress oil, spruce oil, rhubarb oil, turpentine oil, cinnamon oil, bergamot oil, tangerine oil, calamus oil, Examples include pine oil, lavender oil, Pei oil, orange oil, cinnamon oil, cedar oil, clove oil, cypress oil, rose oil, eucalyptus oil, lemon oil, and the like.

In addition, oils include olive oil, soybean oil, almond oil, fallen beef oil, castor oil, coconut oil, palm oil, tardle oil, bran oil, avocado oil, mink oil, egg yolk oil, beef tallow, lanolin, squalene, liquid Paraffin, vaseline, paraffin, etc. can be mentioned.

The bath agent composition of the present invention may contain conventional bath agent components, such as inorganic salts and oils, in addition to the encapsulated product containing the terpene hydrocarbon described above. A bath agent composition consisting of an inorganic salt and the encapsulated product exhibits sufficient bath effects, but a more preferable bath agent composition can be obtained by adding an oil component. In this case, the inorganic salts include, for example, sulfur chloride, potassium iodide, ammonium chloride, sulfur sulfate, aluminum sulfate, potassium sulfide, potassium sulfate, sodium hydrogen carbonate, sodium carbonate, sulfur lithium sesquicarbonate, Magnesium carbonate, magnesium bicarbonate, borax, boric acid, silicic anhydride, metasilicic acid, sodium polyphosphate, calcium hydrogen phosphate,
Examples include 1-lium phosphate, sulfur, and Yunohana. In addition, oils include olive oil, soybean oil, almond oil, fallen beef oil, castor oil, coconut oil, palm oil,
