Description

The present invention relates to cosmetics.

BACKGROUND ART Cosmetics in the form of lotions, milky lotions, mists and the like are used for the purpose of imparting a feeling of moisture to the skin and hair. As such a cosmetic, for example, a moisturizing cosmetic containing trimethylglycine, a water-soluble alkylene oxide derivative that is liquid at 25° C., and a polyhydric alcohol is known (Patent Document 1).

EXAMPLES The present invention will be described in detail below with reference to Examples, but the present invention is not limited to these Examples. In addition, content represents "mass %."

Cosmetics of Examples 1 to 7 and Comparative Examples 1 to 4 were prepared according to the compositions shown in Table 1 and evaluated by the following evaluation methods. The results are also shown in Table 1. In addition, Example 1 is a reference example.

(Evaluation method)
A panel of 10 experts evaluated the "skin compatibility" and "no squeaky feeling" when 1.0 g of the cosmetic was applied to the entire face after washing the face, and the "no stickiness" and "moisturizing feeling of the skin" after application. ” was evaluated according to the following criteria. The results are shown as the average value of 10 people.

(Evaluation criteria)
5 points: very good 4 points: good 3 points: somewhat good 2 points: neutral 1 point: bad 0 points: very bad
