Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a transparent cosmetic,
More specifically, the present invention relates to a cosmetic which has reduced stickiness of a water-soluble L-ascorbic acid derivative and is excellent in transparency.

[0002]

2. Description of the Related Art Conventionally, cosmetics having a transparent appearance have been marketed in order to provide a visually and tactile refreshing feeling and freshness. These transparent cosmetics are generally composed of only an aqueous component or those obtained by solubilizing an oil component using a surfactant. On the other hand, various water-soluble L-ascorbic acid derivatives have been used for the purpose of imparting a whitening effect and an antioxidant effect.

[0003]

However, when an attempt is made to apply a water-soluble L-ascorbic acid derivative to a transparent cosmetic, there is a problem that a sticky feeling is caused by simply dissolving the derivative in an aqueous system. Therefore, there was a difference in the refreshing sensation and freshness from the appearance and the feel when actually used, and a transparent cosmetic having the sensation of use according to the image could not be obtained. Also, when trying to suppress the sticky feeling by blending oil, good transparency cannot be obtained,
When a large amount of a surfactant is blended and solubilized to make it transparent, there has been a problem that the solubilizing agent intensifies the stickiness. Therefore, there has been a demand for the development of a transparent cosmetic having less sticky feeling, excellent feeling in use, and good transparency even when a water-soluble L-ascorbic acid derivative is blended.

[0004]

[Means for Solving the Problems] In view of such problems,
The present inventors have conducted intensive studies and found that by adding a specific modified dimethylpolysiloxane, it was possible to obtain a transparent cosmetic in which the sticky feeling of a water-soluble L-ascorbic acid derivative was reduced, and the present invention. It was completed.

That is, the present invention comprises the following components (A) and (B); (A) a water-soluble polyether-modified dimethylpolysiloxane; (B) a water-soluble L-ascorbic acid derivative; Is 0.1% by weight or less. Further, the transparent cosmetic is characterized in that the HLB of the water-soluble polyether-modified dimethylpolysiloxane of the component (A) is 10 or more. Furthermore, the transparent cosmetic is characterized in that the compounding weight ratio of the component (A) to the component (B) is (A) :( B) = 1: 0.1 to 1:10. The details will be described below.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Component (A) used in the present invention
Is a polyether-modified dimethylpolysiloxane in which a part of the methyl groups of the dimethylpolysiloxane is modified with a polyether such as (poly) oxyethylene and / or (poly) oxypropylene. Any of them can be used, but those having an HLB of 10 or more are preferred. Specifically, KF351A, KF35
3A, KF354A, KF615A, KF618, KF
6011, KF6013 (Shin-Etsu Chemical Co., Ltd.),
SILWET L-77, L-7604, L-760
5, L-7607, FZ-2104, FZ-2161,
FZ-2162, FZ-2163, SS-2801, S
S-2802, SS-2804 (both manufactured by Nippon Unicar), SH3746, SH3771 (both manufactured by Toray Dow Corning Silicone Co., Ltd.) and the like, and one or more of these may be appropriately selected depending on the purpose. Can be used.

The amount of component (A) is not particularly limited and can be appropriately selected according to the dosage form.
The content is 1 to 30% by weight (hereinafter simply referred to as "%"), and more preferably 0.1 to 20%.

The water-soluble L-ascorbic acid derivative of the component (B) used in the present invention is not particularly limited as long as it is water-soluble. Specifically, sodium L-ascorbate, potassium L-ascorbate and L-ascorbate -Magnesium ascorbate, sodium L-ascorbate,
Magnesium L-ascorbate, calcium L-ascorbate, sodium L-ascorbate, magnesium L-ascorbate, calcium L-ascorbate, and the like. One or more of these may be appropriately selected. Can be blended.
Among these, magnesium L-ascorbate, sodium L-ascorbate and sodium L-ascorbate are preferred.

The amount of component (B) is not particularly limited, but is preferably 0.01 to 5%, more preferably 1 to 5%.
~ 5%. In addition, the above-mentioned component (A) and component (B)
(A) :( B) = 1: 0.1 to 1:10
When it is blended, the feeling of stickiness is further reduced and the transparency is good, and the effect of the present invention is remarkable.

Further, in the transparent cosmetic of the present invention,
It is essential that the content of the oil agent is 0.1% or less,
What does not substantially contain an oil agent may be used. If the oil content exceeds 0.1%, it is difficult to obtain good transparency, and even if a large amount of a solubilizing agent is blended to impart transparency, a sticky feeling is caused by this. Good cosmetics cannot be obtained. The oil agent is not particularly limited as long as it is generally used in cosmetics, and natural animal and vegetable oils, hydrocarbon oils, higher fatty acids, higher alcohols,
Ester oils, glyceride oils, silicone oils, fluorinated oils and the like can be mentioned, and one or more of these can be used in the amounts described above.

The transparent cosmetic in the present invention means a transparent cosmetic having a transparency of 90 to 100 when the transparency of distilled water is 100 as a control. If the transparency is less than 90, the system becomes translucent to cloudy, which is not preferable in appearance.

[0012] In the transparent cosmetic of the present invention, in addition to the above essential components, components generally further incorporated into cosmetics, for example, surfactants, powders, water-soluble polymers, organic acid salts, humectants, preservatives , Fragrances, various chemicals and the like can be blended within a range that does not impair the effects of the present invention.
