examples

[0069]The present invention will now be described in further detail with reference to examples, but is not limited to such examples. In the following examples, the terms part(s) and % denote part(s) by mass and % by mass, respectively, unless otherwise specified.

[0070]In the examples, lip cosmetics were evaluated as follows:[0071](1) Appearance

[0072]Lip cosmetics were observed by the naked eye and evaluated according to the following criteria:

[0073]O: having uniform appearance and being in a gel or solidified form,

[0074]X: having nonuniform appearance, being in a liquid form, or exhibiting separation.[0075](2) Application

[0076]Ten monitors used the lip cosmetics and evaluated them according to the following evaluation criteria. The results are shown as average of evaluation by the ten monitors.

[0077]O: being smoothly applied on lips without any problem,

[0078]X: being too hard or too soft and having difficulty in applying the lip cosmetic on lips.[0079](3) Makeup Lasting Quality

[0080...

examples 1 to 3

[0090]Lip cosmetics having the formulae shown in Table 1 were produced. First, the ingredients of the oil phase were weighed in a beaker at the ratio shown in Table 1 to prepare a mixture solution. This mixture solution was heated to 70° C. The unit of numerals in Table 1 is %.

[0091]At the same time, the ingredients of the polyol phase were weighed in a beaker, and the resulting mixture solution was heated to 70° C. as in the oil phase. Then, the heated polyol phase was gradually added to the oil phase over 20 min under propeller stirring at 1000 rpm. After the completion of the addition, the mixture was further stirred for 5 min. Then, the mixture was poured into a jar container and was cooled to room temperature to obtain a lip cosmetic in a gel form. The resulting lip cosmetic was subjected to the above-described evaluation. Table 2 shows the evaluation results.

[0094]Lip cosmetics were produced by the same procedure as that in Examples 1 to 3, except that the formulae were those shown in Table 3. In Table 3, polyglyceryl-10 (behenate / eicosadioate), glyceryl (behenate / eicosadioate), diisostearyl malate, and hydrogenated polyisobutene were the same as those in Examples 1 to 3. The resulting lip cosmetics were subjected to the above-described evaluation. Table 4 shows the evaluation results.

Abstract

[Object] To provide lip cosmetics which are excellent in the sense of use such as smoothness and adhesion upon application, excellent in moisturizing and protecting properties for lips, and excellent in long-term stability.
[Solving Means] A lip cosmetic of the present invention contains the following ingredients (a) to (e): (a) an oligomer produced from behenic acid, eicosane diacid, and a glycerin condensate; (b) a polyol; (c) water; (d) an ester oil composed of a carboxylic acid having 2 to 36 carbon atoms and an alcohol having 1 to 36 carbon atoms and being in a liquid or paste form at ordinary temperature; and (e) an oily gelling agent.

Description

TECHNICAL FIELD [0001]The present invention relates to lip cosmetics. Specifically, the present invention relates to lip cosmetics which are excellent in the sense of use such as smoothness and adhesion upon application, excellent in moisturizing and protecting properties for lips, and excellent in long-term stability.BACKGROUND ART [0002]In general, skin care cosmetics are produced by emulsifying oily ingredients and aqueous ingredients using surfactants. The oily ingredients are used for adding emollient properties to the cosmetics, and the aqueous ingredients are used for adding moisturizing properties to the cosmetics. Furthermore, there is also a tendency that makeup cosmetics are required to have excellent moisture-retaining properties or water-holding properties, and various developments have been conducted. In makeup cosmetics, particularly, in lip cosmetics, the blending of water has been attempted for a long time.[0003]For example, Patent Documents 1 to 3 disclose emulsifi...
