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] Most emollients for facial or body use are in liquid form and are applied directly. Therefore, even if the formulation was slightly improved, the oil tends to feel sticky when used because the oil is applied to the face and body.

Additionally, emollients that dissolve in books or hot water have been proposed, but although they are light, the composition has a drawback in low-temperature stability, and when left at low temperatures, the system becomes cloudy or gels. was there.

[Problems to be Solved by the Invention] “The present inventors have conducted intensive research in order to obtain an emollient agent that has a sharp feeling of use and has excellent low-temperature stability. It has been discovered that these problems can be solved by blending specific amounts of an activator and water, respectively, and the present invention has been completed.

[Means for Solving the Problems] That is, the present invention comprises 30 to 98% by weight of one or more liquid oil components and 2 or more of one or more nonionic surfactants having an HLB of 2 to 10. 40% by weight and 0.01 to 5% by weight of water.

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, tardle 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, pristane, 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, silicones such as methylpolysiloxane, methylphenylpolysiloxane, methylhydrodienepolysiloxane, decamethylpolysiloxane, isopropyl myristate, isopropyl palmitate, hexyl laurate, Octyldodecyl myristate, hexyldecyl dimethyloctanoate, diethyl phthalate, dibutyl phthalate, isopropyl cepatate, diisopropyl cepatate, di-2 cepatate

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

The amount of water blended is 0.01 to 5% by weight, preferably 0.
．． It is 1 to 3% by weight. If it is less than 0.01% by weight, the system becomes cloudy or gels, and if it exceeds 5% by weight, the system separates, which is not preferable.

It is preferable to incorporate extracts or extracts of crude drugs into the present invention from the viewpoint of skin protection effects. These crude drugs are preferably those that are liquid at room temperature, and examples thereof include Angelica japonica, Nebula japonica, Chamomile, Chinpi, Hamabofu, Loofah, Calamus, and Momotsuba. The blending amount is 0.
01 to 5% by weight is preferred.

In the present invention, fragrances, pigments, humectants, antioxidants, ultraviolet absorbers, etc. can be added to the extent that the effects are not significantly impaired.

[Effect of the invention] The oil-containing composition of the invention has excellent stability at low temperatures,
It has excellent emulsifying and dispersing properties in water or hot water, leaves a dry residue after use, and when combined with crude drugs, etc., the skin protection effect is further improved.
