DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-based cosmetic composition formed by shaping a water-soluble component into a stick, and more particularly to one or more dihydric alcohols and an average molecular weight of 10,000. One or more selected from polyalkylene glycols of up to 20,000;
An aqueous stick cosmetic comprising an aqueous component.

[0002]

2. Description of the Related Art Stick-shaped cosmetics in the form of sticks are easy to use and convenient to carry.
It has been widely provided as an antiperspirant and deodorant cosmetic such as a deodorant stick, and a makeup cosmetic such as a lip balm, a lipstick, a stick-type eye color, a stick-type cheek color and the like.

[0003] However, conventional stick-shaped cosmetics are mainly composed of an oily component and solidified with a solid wax or an oil gelling agent, or solidified after mixing fatty acid soap with ethanol. Oily components solidified with solid wax etc. have a strong oily feeling in use,
Also, it was difficult to contain a considerable amount of water-soluble components such as humectants. On the other hand, in the case of soap and alcohol-based stick cosmetics, the pH of the cosmetic
And when used on the skin, there is a problem that a gentle feeling of use is lacking.

[0004]

Accordingly, in the present invention, in order to eliminate the oily feeling and to allow a water-soluble component to be contained, an aqueous stick-like cosmetic formed by shaping the water-soluble component into a stick is provided. The purpose was to provide.

[0005]

As a result of various studies to solve the above problems, one or more dihydric alcohols and a polyalkylene glycol having an average molecular weight of 10,000 to 20,000 were selected. One or two or more,
By containing an aqueous component in a specific weight ratio,
It has been found that a stable aqueous stick having sufficient strength and moldability can be obtained, and the present invention has been completed.

[0006]

With respect to Examples 1 to 4, the stick formability, hardness and stability were evaluated. At that time, Comparative Examples 1 to 6 shown in Table 2 were also evaluated at the same time. These comparative examples were also prepared in the same manner as in the above example.

[Table 2]

The moldability of the stick was evaluated immediately after the preparation of each example and comparative example.
“Somewhat bad; △” and “Bad; ×”. The hardness was measured with a penetrometer and expressed as “moderate; ○”, “somewhat too hard or too soft; Δ”, “too hard or too soft; ×”. Regarding the stability, each of the examples and comparative examples was allowed to stand at 5 ° C., 25 ° C. and 50 ° C. for one month, and it was observed whether or not any change in state such as a change in hardness, precipitation or exudation of the compound components was observed. , "Good;○",
“Somewhat bad; △” and “Bad; ×”. Table 3 shows the results of the evaluation.
