CONSTITUTION:The subject composition, obtained by filling a composition containing (A) 30-98wt.%, preferably 60-90wt.% liquid oil ingredient with (B) 2-40wt.%, preferably 4-30wt.% on or more nonionic surfactants selected from glycerol esters, fatty acid esters, alkyl ethers and alkyl phenyl esters, having 2-10 HLB and containing polyoxyethylene chains in the molecule as essential ingredients in soft capsules and capable of readily mixing the oil ingredient with water or hot water, homogeneously emulsifying the mixture and imparting emollient, skin beautifying, fat-liquoring and medicinal effects, etc., to the face or body with refreshing residue of usability.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention provides an emollient effect, a beautifying effect, a fatliquing effect, a medicinal effect, etc. to the face or body by dissolving it in water or hot water and using it. In more detail, the present invention relates to a composition that has excellent low-temperature stability, and when dissolved in water or hot water, an oil component easily mixes with the water or hot water, resulting in a uniform emulsion.

[Prior Art] Emollients for facial or body use.
Most of these formulations were liquid and were applied directly. Even though the formulation was slightly improved since it was a side dish, the oil tended to feel sticky when used because the oil was applied to the face and body.

Also, emollients that dissolve in water or hot water have been proposed, but they are sharp but have a drawback in their emulsifying properties.

[Problems to be Solved by the Invention] The present inventors have conducted intensive research in order to obtain an emollient agent that has a light feel and has excellent emulsifying properties. The inventors have discovered that these problems can be solved by incorporating specific amounts of these agents into soft capsules, and have completed the present invention.

[Means for Solving the Problems] That is, the present invention provides a solution containing 30 to 98% by weight of one or more liquid oil components, an HLB of 2 to 10, and a glycerin fatty acid containing a polyoxyethylene chain. A composition comprising 2 to 40% by weight of one or more nonionic surfactants such as esters, fatty acid esters, alkyl ethers, and alkylphenyl ethers,
This is an oil-containing soft capsule composition obtained by filling soft capsules.

The configuration of the present invention will be described below.

The liquid oil used in the present invention has a viscosity of 2000p at 30°C.
The following are preferred, such as avocado oil, camellia oil, turdle oil, macadamia nut oil, corn oil, mink oil, olive oil, rapeseed oil, egg yolk oil, sesame oil,
Basic oil, wheat germ oil, sasanquat oil, castor oil, linseed oil, safflower oil, cottonseed oil, eno oil, soybean oil, peanut oil, tea seed oil, kaya oil, rice bran oil, shinakiri oil, Japanese tung oil, jojoba oil , germ oil, liquid oils and fats such as triglycerin, glyceryl trioctanoate, and glycerin triisopalmitate, hydrocarbons such as liquid paraffin, squalene, blistane, and squalane, higher fatty acids such as oleic acid, tall oil, and isostearic acid, lauryl alcohol,
Higher alcohols such as oleyl alcohol, isostearyl alcohol, octyldodecanol, silicone such as methylpolysiloxane, methylphenylpolysiloxane, methylhydrodienepolysiloxane, decamethylpolysiloxane, isopropyl myristate, isopropyl valmitate, hexyl laurate, Octyldodecyl myristate, hexyldecyl dimethyloctanoate, diethyl phthalate, dibutyl phthalate, isopropyl cepatate, diisopropyl cepatate, di-2 cepatate
-ethylhexyl, glyceryl triisostearate,
Trimethylolpropane triisostearate, glycerin tri-2-ethylhexanoate, trimethylolpropane tri-2-ethylhexanoate, neopentyl glycol capriate, glycerin di-2-hebutylundecanoate, cetyl 2-ethylhexanoate, myristyl myristate , oleyl oleate, hexyl oleate,
Examples include esters such as decyl oleate.

The amount of liquid oil used in the present invention is 30 to 98% by weight, preferably 60 to 90% by weight.

The nonionic surfactant used in the present invention has an HLB of 2.
~10, with a polyoxyethylene chain (hereinafter P
Glycerin fatty acid esters containing (referred to as OE),
These are fatty acid esters, alkyl ethers, and alkylphenyl ethers. Examples of these include POE glycerin fatty acid esters such as POE glycerin monostearate, POE glycerin monoisostearate, and POE glycerin triisostearate;
POE fatty acid esters such as OE monooleate, POE distearate, POE monodioleate, POE ethylene glycol distearate, POE lauryl ether, POE oleyl ether, POE stearyl ether, POE behenyl ether, POE 2-octyl dodecyl ether, POE cholestanol ether, etc.
Examples include OE alkyl ethers, POE alkylphenyl ethers such as POE octylphenyl ether, POE nonylphenyl ether, and POE dinonylphenyl ether.

The amount of the nonionic surfactant of the present invention is 2 to 40% by weight, preferably 4 to 30% by weight. If it is less than 2% by weight, when ice crystals are dissolved in water or hot water, the emulsifying power will be weak or they will float on the surface of the water or hot water. 40
Exceeding this percentage by weight is unfavorable from the standpoint of safety.

Note that it is preferable to mix water and/or a lower alcohol with the liquid oil and a nonionic surfactant in the soft capsule of the present invention because stability at low temperatures is improved. The blending amounts of water and lower alcohol are preferably 0.01 to 5% by weight.

It is preferable to blend extracts or extracts of crude drugs into the soft capsules of the present invention from the standpoint of skin protection. These crude drugs are preferably those that are liquid at room temperature, and examples include trumpet root, nebula, chamomile, chinpi, hambofu, loofah, calamus, peach root, and the like. The compounding amount is
In both cases, 101 to 5% by weight of O is preferable.

The soft capsules of the present invention may contain fragrances, pigments, humectants, antioxidants, ultraviolet absorbers, and the like, as long as the effects are not significantly impaired.

From the above, the obtained liquid composition has a jelly strength of 150 to
The viscosity is adjusted to 15,000 cps or more at 60° C. by adding 20 to 60 parts by weight of glycerin and water to 100 parts by weight of gelatin of 250 bloom, and the resulting product is filled into soft capsules.

[Effect of the invention 1] The oil-containing soft capsule composition of the present invention has excellent emulsion dispersibility in water or hot water, leaves a dry residue after use, and has a further skin protective effect due to the combination of herbal medicines, etc. It is something that can be improved.

[Example] Next, a detailed description will be given based on a comparative example and an example. The present invention is not limited to these examples. In addition, the blending amount represents weight %.
