Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a translucent or transparent cosmetic, and more particularly, to a translucent or transparent cosmetic stably blended with an oil or an oil-soluble drug exhibiting a moisturizing effect on the skin or a skin improving effect. Related to cosmetics.

[0002]

2. Description of the Related Art In recent years,
Cosmetics that are translucent or transparent on the appearance of fine oil particles are giving preference to the skin because they give a gentle feeling to the skin and can also achieve a wide range of use feeling and skin improvement effects that are favorable to tastes. It has been widely used not only for skin care products but also for body care products.

[0003] However, for example, by making the oil component or oil-soluble drug into ultrafine particles, cosmetics that are expected to have higher penetration into the skin and an effect of improving the skin have excellent stability over time and can be easily manufactured. There are no transparent cosmetics with extremely high transparency. Also, in translucent cosmetics,
If a high-pressure emulsifying machine is used to make oil into fine particles to obtain a translucent cosmetic, the high-pressure emulsifying machine must be passed many times, requiring a long production time and a limited amount of production. There is. In addition, for example, Japanese Patent Application Laid-Open No. 63-132814
JP-A-64-47710 and JP-A-64-47710 disclose a method for easily obtaining a translucent cosmetic using a specific surfactant, but even if the long-term stability in a standing state is good, Vibration caused by transportation to the user or shaking during use by the user causes a phenomenon in which the translucency changes, often resulting in a disadvantage of losing commercial value.

[0004] The present invention has been made in view of the above-mentioned conventional circumstances, has excellent long-term stability, vibration and shaking stability, and has a wide use feeling that can respond to diversifying consumer preferences. An object of the present invention is to provide a translucent or transparent cosmetic which has a skin improving effect and can be freely adjusted from translucent, which can be easily produced, to extremely high transparency.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, the oil containing a branched saturated fatty acid which is liquid at room temperature is finely divided using a hydrophilic surfactant. Then it can be freely adjusted from translucent to extremely high transparency, it can be easily manufactured, it has excellent long-term stability and vibration and shaking stability, and it is hardly affected by various ingredients mixed in cosmetics The present inventors have found that a cosmetic having a use feeling and a skin improving effect that can respond to a wide range of tastes can be obtained, and have completed the present invention.

[0006] That is, the present invention is a translucent or transparent cosmetic comprising an oil containing a branched saturated fatty acid which is liquid at normal temperature and a hydrophilic surfactant. In the present invention, transparent or translucent is measured using a digital colorimetric color difference calculator manufactured by Suga Test Instruments Co., Ltd. Say.

[0007]

Embodiments of the present invention will be described below. Examples of the branched saturated fatty acid at room temperature which is used in the translucent or transparent cosmetic of the present invention include 2-

(Preparation method) In the aqueous phase of A dissolved by stirring, 5
The surfactant-oil mixed phase of B uniformly dissolved at 0 ° C. was added with stirring to obtain a translucent medicated whitening lotion.

As is clear from the results shown in Tables 1 and 2, the proportion of the branched saturated fatty acids which are liquid at normal temperature in the oil component is 1%.
If it is less than 0% by weight, good translucency can be obtained, but stability by a shaking test is poor. On the other hand, if it exceeds 80.0% by weight, it becomes difficult to obtain good translucency. Therefore, the ratio of the branched saturated fatty acid that is liquid at a suitable normal temperature to the oil component is 1.0 to 80.0% by weight.

(Preparation method) In the aqueous phase of A dissolved by stirring, 6
The surfactant-oil mixed phase of B uniformly dissolved at 0 ° C. was added with stirring to obtain a translucent moisturizing serum.

As is clear from the results of Tables 4 and 5, when the oil content is not blended or less than 0.01% by weight, the overall evaluation of the use test is low, and when the oil content exceeds 20.0% by weight, the oil content exceeds 20.0% by weight. In order to obtain good translucency, the amount of the surfactant must be increased, and the feeling of use becomes sticky, so that the overall evaluation of the use test is lowered. Therefore, a suitable amount of the oil component is 0.01 to 20.0% by weight.
