No. 86 describes a method of solubilizing a fragrance by blending 3-methoxy-3-methyl-1-butanol (MMB).

[0003]

SUMMARY OF THE INVENTION However, MMB
When trying to prepare a transparent aqueous composition with only the formulation,
A large amount of MMB was required, and the use feeling was sometimes slim. Further, even when a transparent composition is prepared by blending a large amount of MMB, it may become cloudy if left at a low temperature of 0 ° C. or lower or once frozen. The present invention has been made in view of the problems of the prior art, and its object is to
An object of the present invention is to provide a water-based composition in which MB is used in an amount of 20% by weight or less and has high transparency immediately after production and after storage at low temperature.

[0004]

Means for Solving the Problems In order to achieve the above object, the present inventors have conducted intensive studies, and as a result, blended a hydrocarbon as at least a part of an oily component, and together with MMB,
By using a small amount of a surfactant in combination, it was found that a clear aqueous composition having excellent stability was obtained without causing cloudiness even when stored at a low temperature, and the present invention was completed.

That is, the transparent aqueous composition of the present invention contains an oil component, water, 3-methoxy-3-methyl-1-butanol, and a surfactant, and the oil component contains at least a hydrocarbon. It is characterized by the following. In the present invention,
Suitably, the hydrocarbon is from 0.01 to 2% by weight of the composition.

It is preferable that 3-methoxy-3-methyl-1-butanol is contained in the composition in an amount of 0.1 to 20% by weight. It is preferable that the oil component is 0.01 to 10% by weight in the composition. Further, it is preferable that the weight ratio between the surfactant and the oil component is 1: 2 to 2: 1. Further, it is preferable that water is 60% by weight or more in the composition. It is preferable that the composition of the present invention does not substantially contain ethanol.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One feature of the present invention is that it contains at least a hydrocarbon as an oily component.
Examples of the hydrocarbon include liquid paraffin, squalane, pristane, isoparaffin, squalene, petrolatum, microcrystalline wax, and the like, preferably a liquid hydrocarbon oil, and more preferably a saturated hydrocarbon oil.

[0008] The compounding amount of the hydrocarbon is 0.01 to
2% by weight. If the amount of the hydrocarbon is too small, the effect of the present invention cannot be sufficiently obtained. On the other hand, if the amount is too large, the transparency is rather lowered. In the present invention, in addition to the above-mentioned hydrocarbons, oils and fragrances usually used in cosmetics and aroma compositions can be used as the oily component. Examples of oils include oils and fats, higher fatty acids, higher alcohols, ester oils, waxes, silicone oils, and sterols.

The fats and oils include linseed oil, camellia oil, macadamia nut oil, corn oil, mink oil, olive oil, avocado oil, sasanqua oil, castor oil, safflower oil, kyonin oil, cinnamon oil, jojoba oil, grape oil,
Sunflower oil, almond oil, rapeseed oil, sesame oil, wheat germ oil, rice bran oil, cottonseed oil, soybean oil, peanut oil, teaseed oil,
Evening primrose oil, egg yolk oil, beef tallow, liver oil, triglycerin, glycerin trioctanoate, glycerin triisopalmitate and the like. Oleic acid as a higher fatty acid,
Tall oil, isostearic acid and the like. Higher alcohols include lauryl alcohol, oleyl alcohol, isostearyl alcohol, octyldodecanol, and the like.

Esters include isopropyl myristate, isopropyl palmitate, hexyl laurate, octyldodecyl myristate, hexyldecyl dimethyloctanoate, diethyl phthalate, dibutyl phthalate, isopropyl sebacate, diisopropyl sebacate, diisopropyl sebacate. 2-ethylhexyl glycerin triisostearate, trimethylolpropane triisostearate, glycerin tri-2-ethylhexanoate, tri-
Trimethylolpropane 2-ethylhexanoate, neopentyl glycol dicaprate, glycerin di-2-heptylundecate, cetyl 2-ethylhexanoate, myristyl myristate, oleyl oleate, hexyl oleate, decyl oleate, and the like. .

[0011] Examples of the wax include beeswax and spermaceti. Examples of the silicone oil component include dimethylpolysiloxane, methylphenylpolysiloxane, and methylhydrogenpolysiloxane. Sterols include cholesterol, sitosterol, phytosterol, lanosterol and the like.

If the amount of these oily components is too large, it is difficult to solubilize the composition transparently.
It is. The amount of 3-methoxy-3-methyl-1-butanol (MMB) is 0.1 to 20% by weight in the composition.
Preferably it is 2 to 15% by weight. If the MMB is too small, the effect of the present invention cannot be sufficiently obtained. On the other hand, if the amount is too large, the feeling of use may be slim.

[0013] The surfactant used in the present invention is not particularly limited, and the surfactant usually incorporated in cosmetics may be appropriately selected depending on the type and amount of the oily component to be solubilized. It is an ionic surfactant. The amount of the surfactant is preferably 0.5 to 2 times, more preferably 0.8 to 1.5 times the weight of the oil component. If the amount of the surfactant is too small, the effect of the present invention cannot be sufficiently obtained, and even if the surfactant is excessively added, the effect cannot be expected to increase, and the use feeling may be adversely affected.

The composition of the present invention contains a large amount of water. The amount of water is 60% by weight in relation to other components.
Or more, preferably 70% by weight or more. Hereinafter, the present invention will be further described with reference to specific examples. The appearance was evaluated immediately after production (25 ° C.) and at a low temperature of −10 ° C.
The appearance after storage for a week was observed with the naked eye and indicated as transparent 、, translucent △, and cloudy x. In addition, regarding the sliminess when the sample was applied to the back of the hand, none ○, slight presence △, presence ×
As shown. First, rose-type floral-like fragrance as an oily component, liquid paraffin as a hydrocarbon,
The study was conducted using POE (20) glycerin monoisostearate as a surfactant. Unless otherwise specified, the amounts are shown in% by weight.

As shown in Table 1, it is difficult to prepare a transparent composition using only a small amount of MMB alone or surfactant alone. When MMB and a surfactant are used in combination, the transparency immediately after production is slightly improved, but the transparency after low-temperature storage is not improved. Further, it is difficult to obtain a transparent and stable composition in the case of only hydrocarbon, in the case of hydrocarbon and MMB, and in the case of hydrocarbon and surfactant. In contrast, MMB, hydrocarbons and surfactants
In a system using both of them, a highly transparent composition could be obtained, and no white turbidity occurred even after storage at low temperature. Therefore, the amount of each component was further studied.

As shown in Table 2, the transparency after low-temperature storage is improved as the blending amount of the hydrocarbon increases. In addition, since transparency decreases rather when hydrocarbons increase, the compounding amount of the hydrocarbon in the present invention is 0.01 to 0.01% in the composition.
2% by weight is preferred.

As shown in Table 3, if the amount of the surfactant is too small relative to the oil component, transparency may not be maintained. On the other hand, even if the surfactant is excessively added, an increase in the effect cannot be expected. Therefore, the amount of the surfactant is preferably 0.5 to 2 times, more preferably 0.8 to 1.5 times the weight of the oil component.

As shown in Table 4, even when the amount of MMB is reduced by using a surfactant and a hydrocarbon together,
Transparency after low-temperature storage can be maintained. However,
If the amount of MMB is too small, the transparency is not improved. On the other hand, if it is excessively mixed, slimming may occur. Therefore, the amount of MMB is 0.1 to 20% by weight, further 2 to 15% by weight.
Is preferred.

By using a combination of a surfactant and a hydrocarbon as at least a part of the oily component, it is possible to obtain an aqueous composition which is transparent, does not become cloudy after storage at low temperature, and has a good feeling in use.
