Description

Liquid cosmetics

The present invention relates to a liquid cosmetic, and more particularly, to a white lotion-type refreshing lotion-like liquid cosmetic.

In recent years, cosmetics that have become cloudy in appearance with oily fine particles have become popular because they give skin-friendly feeling and can realize a wide range of usage feeling and skin improvement effects that suit your taste. It is becoming widely used for body care products.

For example, in Patent Document 1, a translucent to transparent lotion-like cosmetic is obtained by using isostearic acid and a hydrophilic surfactant. However, this cosmetic tends to increase the amount of the active agent that causes stickiness when the oil content is increased, so that good usability cannot be obtained.
Further, Patent Document 2 discloses a cloudy cosmetic composition in which a hydrophilic nonionic active agent and a lipophilic nonionic active agent are used in combination, and isostearic acid is blended as an essential component in the oil. However, this cloudy cosmetic material has a drawback that it is difficult to mix a semi-solid oil or a solid oil because it is necessary to carry out the emulsification temperature at a low temperature during mass production.
Patent Document 3 discloses an oil-in-water ultrafine emulsion composition using a polyoxyethylene / polyoxypropylene copolymer dialkyl ether. However, this ultrafine emulsion composition has a drawback in that it is difficult to stably mix solid oil and semi-solid oil.
Thus, in the prior art, when trying to mix solid oil or semi-solid oil in order to improve the usability such as moistness, the stability of the system is impaired, or problems in the manufacturing process occur, It was difficult to blend solid oil and semi-solid oil.

Japanese Patent Laid-Open No. 2001-270807 JP 2005-255667 A JP 2007-15972 A

The present invention has been made in response to the conventional circumstances as described above, and is excellent in long-term stability, and gives a moist feel and emollient effect by stably blending solid and semi-solid oil components. An object of the present invention is to provide a cloudy liquid cosmetic that can be easily manufactured.

That is, the present invention
(1) 0.01-5% by mass of polyoxyethylene / polyoxypropylene copolymer dialkyl ether;
(2) 0.01 to 1.0% by mass of a hydrophilic surfactant selected from polyoxyethylene (30) phytosterol, polyoxyethylene octyldodecyl ether, and polyoxyethylene hydrogenated castor oil;
(3) From sorbitan sesquioleate, sorbitan sesquiisostearate, sorbitan sesquistearate, sorbitan trioleate, polyoxyethylene alkyl (carbon number 12 to 15) ether phosphoric acid (2EO), and polyglyceryl diisostearate 0.001 to 0.5% by mass of the selected lipophilic active agent and (4) 0.01 to 2% by mass of oil, and isostearic acid occupies 20% by mass or more of the component (4) oil. A liquid cosmetic is provided.

According to the present invention, conventionally, divalent glycol was used to dissolve the oil, but a part or all of the divalent glycol was replaced with a polyoxyethylene / polyoxypropylene copolymer dialkyl ether. Increases the cloud point of the activator. This makes it possible to increase the temperature in the production process, and it is possible to blend solid oil and semi-solid oil.
In addition, since the polyoxyethylene / polyoxypropylene copolymer dialkyl ether functions as an active auxiliary agent, a high shearing force is not required and the manufacturing process is simplified.

According to the present invention, a cloudy liquid makeup that is excellent in long-term stability and that can provide a moist feel and emollient effect by stably blending solid and semi-solid oil components, and can be easily produced. It can be a fee.

The best mode of the present invention will be described below.
(1) Polyoxyethylene / polyoxypropylene copolymer dialkyl ether As the polyoxyethylene / polyoxypropylene copolymer dialkyl ether used in the present invention, polyoxypropylene / polyoxypropylene copolymer dimethyl ether, polyoxypropylene -A polyoxyethylene copolymer diethyl ether is mentioned, It is especially preferable that it is a random type.
The polyoxypropylene / polyoxyethylene random copolymer dialkyl ether can be produced by a known method. For example, it can be obtained by addition-polymerizing ethylene oxide and propylene oxide to a compound having a hydroxyl group, and then ether-reacting an alkyl halide in the presence of an alkali catalyst.
The average addition mole number of oxypropylene is 1 to 10, the average addition mole number of oxyethylene chain is 9 to 100, and the ratio of the average addition mole number of oxyethylene to the total addition mole number of oxyethylene and oxypropylene [POE / (POE + POP)] is preferably 0.5 to 0.9. Here, POE refers to polyoxyethylene and POP refers to polyoxypropylene.

The blending amount of the polyoxyethylene / polyoxypropylene copolymer dialkyl ether is 0.01 to 5% by mass, preferably 0.3 to 3% by mass, based on the total amount of the liquid cosmetic. If the polyoxyethylene / polyoxypropylene copolymer dialkyl ether is too little or too much, the particle tends to be large and the stability tends to be poor.

(2) Hydrophilic surfactant The hydrophilic surfactant used in the present invention is selected from polyoxyethylene (30) phytosterol, polyoxyethylene octyldodecyl ether and polyoxyethylene hydrogenated castor oil. When a hydrophilic surfactant other than the above components is used, the oil cannot be blended stably and separation occurs at a high temperature.
