Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cosmetic composition obtained by solubilizing a formulation component that is poorly soluble in water, such as a lotion, as a solubilizing agent for the formulation component that is poorly soluble in water. , An invention belonging to the technical field relating to cosmetics containing a combination of specific surfactants.

[0002]

2. Description of the Related Art Among cosmetics, for example, like lotion,
Generally, ingredients that are hardly soluble in water, such as fragrances and oils, which are added to cosmetics which are supposed to be transparent, are solubilized by an appropriate solubilizing agent. As the solubilizing agent, polyoxyethylene alkyl ether, which is a non-ionic surfactant having a large hydrophilicity, particularly polyoxyethylene octyldodecyl ether having 10 to 25 mol of ethylene oxide added is generally used. (Japanese Patent Publication No. 60-33806).

However, polyoxyethylene octyldodecyl ether, which has been widely used as a solubilizing agent, is relatively excellent in solubilizing power, but if it is attempted to be sufficiently solubilized, a cosmetic composition containing it will be obtained. It tends to have a sticky feel. In particular, for cosmetics that require a refreshing feel such as lotion, it is required to remove this sticky feel as much as possible.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention provides a cosmetic composition obtained by solubilizing a poorly water-soluble formulation component such as a lotion and the like. It is to provide a means for solubilizing without sticky feeling.

[0005]

Means for Solving the Problems The inventors of the present invention have made extensive studies to solve the above problems. As a result, a polyoxyethylene type nonionic surfactant, which has been widely used as a solubilizer, has been added to "polyoxyethylene octyldodecyl ether having 10 to 25 moles of added ethylene oxide". When combined with a polyhydric alcohol ester type nonionic surfactant, "polyoxyethylene hydrogenated castor oil having the same addition mole number of 40 moles or more and 80 moles or less", the solubilizing power is dramatically improved. As a result, even if the amount of solubilizer added is small,
It has been found that it is possible to sufficiently solubilize a formulation component that is poorly soluble in water, and as a result, it is possible to provide the above-mentioned cosmetic composition in which the sticky feeling associated with the formulation of the solubilizer is removed. .

That is, the present inventor provides the following inventions in the present application.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. The present invention is an invention relating to a cosmetic composition obtained by solubilizing a formulation component that is sparingly soluble in water (hereinafter, also referred to as a sparingly soluble component). Say.

First, "polyoxyethylene octyldodecyl ether having 10 to 25 moles of added ethylene oxide (hereinafter also referred to as POE (10 to 25) octyldodecyl ether") to be added to the solubilized cosmetic composition of the present invention. Will be described.

The POE (10-25) octyldodecyl ether is a polyoxyethylene type nonionic surfactant which is usually produced by addition-polymerizing 10 to 25 mol of ethylene oxide with 2-octyldodecyl alcohol. , Its manufacturing method is established.

POE (10-25) octyldodecyl ether is usually due to its excellent solubilizing power and emulsifying power,
It is widely used as an emulsifier or solubilizer for cosmetics.

POE blended in the solubilized cosmetic of the present invention
As the (10 to 25) octyldodecyl ether, it is possible to use those manufactured by the established manufacturing method, but it is of course possible to use commercially available products. POE
Examples of commercially available products of (10 to 25) octyldodecyl ether include "Emalex" manufactured by Nippon Emulsion Co., Ltd.
Examples include OD-16, the same 20, the same 25 ", and" Nonion IP-220 "manufactured by NOF Corporation.

This POE in the solubilized cosmetic of the present invention
The compounding amount of (10 to 25) octyldodecyl ether is
0.1% by weight or more and 2.0% by weight based on the total amount of cosmetics
It is the following. When the amount is less than 0.1% by weight based on the total amount of the cosmetic, the poorly soluble component cannot be sufficiently solubilized and it is difficult to achieve the object of the present invention, which is not preferable. On the other hand, if it is blended in an amount of more than 2.0% by weight with respect to the total amount of the cosmetic, it tends to have a sticky feeling.
The use of polyoxyethylene hydrogenated castor oil, which will be described later, in combination is unfavorable because it is less meaningful.

Next, the PO is added to the solubilized cosmetic composition of the present invention.
"Polyoxyethylene hydrogenated castor oil having an added mole number of ethylene oxide of 40 moles or more and 80 moles or less (hereinafter, also referred to as POE (40-80) hydrogenated castor oil)" blended with E (10 to 25) octyldodecyl ether Will be described.

POE (40-80) hydrogenated castor oil, which is a polyhydric alcohol ester type nonionic surfactant, is
Hydrogenated castor oil obtained by curing hydrogen by adding hydrogen to the double bond of castor oil is obtained by addition-polymerizing 40 to 80 mol of ethylene oxide, and is mainly used as a solubilizer or an emulsifier.

POE incorporated in the solubilized cosmetic of the present invention
As the (40 to 80) hydrogenated castor oil, it is possible to use the one produced by the established production method, but it is of course possible to use a commercially available product. Examples of commercially available POE (40-80) hydrogenated castor oil include "Emalex HC-40, 50, 60, 8" manufactured by Nippon Emulsion Co., Ltd.
0 "," NIKKOL HCO- "made by Nikko Chemicals
40, 50, 60, 80 ″ and the like.

This POE in the solubilized cosmetic of the present invention
The blending amount of (40-80) hydrogenated castor oil is 0.1% by weight or more and 2.0% by weight or less based on the entire cosmetic.
When the amount is less than 0.1% by weight based on the total amount of the cosmetic, the poorly soluble component cannot be sufficiently solubilized and it is difficult to achieve the object of the present invention, which is not preferable.
On the other hand, if it is blended in an amount of more than 2.0% by weight with respect to the total amount of the cosmetic, it tends to be accompanied by a sticky feeling, and the meaning of blending it in combination with the aforementioned polyoxyethylene octyldodecyl ether is diminished. Not preferable.

Further, POE (10 to 25) octyldodecyl ether and PO which can be incorporated into the solubilized cosmetic composition of the present invention.
The total of E (40 to 80) hydrogenated castor oil is in the range of 0.2% by weight or more and 2.1% by weight or less with respect to the entire cosmetic. If the blending amount is less than 0.2% by weight with respect to the total amount of the cosmetic, the poorly soluble component cannot be sufficiently solubilized, and it is difficult to achieve the object of the present invention, which is not preferable. On the contrary, if it is blended in an amount of more than 2.1% by weight with respect to the total amount of the cosmetic, it tends to be accompanied by a sticky feeling, and it becomes difficult to achieve the intended purpose of the present invention.

In this way, POE is used as the solubilizing agent.
(10-25) Octyl dodecyl ether and POE (4
(0 to 80) By adding hydrogenated castor oil in combination to the solubilized cosmetic composition of the present invention, the solubilization power is dramatically improved as compared with the case where each of them is mixed in an equal amount, and as a result, solubilization is performed. It is possible to reduce the compounding amount of the above-mentioned nonionic surfactant as an agent. As a result, it is possible to provide a solubilized cosmetic composition that does not cause a sticky feeling, even though the poorly soluble component is sufficiently solubilized.
