Description

  The present invention relates to an oily solid cosmetic.

  Skin care cosmetics are generally intended to be applied over a wide area such as the entire skin of the face or body, and cosmetics with good growth are preferred. As such skin care cosmetics, many emulsions and creams are used. However, recently, cosmetics for partial use have been studied in order to deal with troubles only on certain parts of the body (for example, stains). For example, there is a stick-like whitening solid cosmetic as described in Patent Documents 1 and 2 for skin care by concentrating locally.

Examples 1-8, Comparative Examples 1-4
An oily solid cosmetic material having the composition shown in Table 1 was produced, and the adhesion amount and the difficulty of seeing color unevenness were evaluated. The results are also shown in Table 1.

(Production method)
Polyoxyethylene hydrogenated castor oil is added to the component (A), and the component (C) is further dispersed therein under the conditions of 3000 rpm and 30 min (mixture 1). Next, the component (B) is heated and melted at 105 ° C. in advance, and the mixture 1 is added to the molten component (B) with stirring with a propeller to make it uniform (mixture 2). After the mixture 2 is cooled to 85 ° C., 1,3-butylene glycol and ethanol are added, degassed, poured into a mold, left to cool in a 4 ° C. cooling tank, taken out from the mold, and oily. A solid cosmetic was obtained.

(Evaluation method)
(1) Amount of adhesion:
The oily solid cosmetic was molded into a cylindrical shape having a diameter of 1 cm, and the cylindrical tip was molded so as to be a plane substantially perpendicular to the side surface. It is applied to the artificial leather (Celanu back black (manufactured by Okamoto Chemicals Co., Ltd.)) affixed to the measuring table of the balance, and applied at a pressure at which the scale of the balance enters 300 to 350 g. As the coating conditions, 5 straight lines of 5 cm were drawn, the total adhesion amount was divided by 5, and the average value per straight line was obtained. This operation was performed 5 times, and the average value of the 5 times was defined as the final adhesion amount.

(2) Difficulty in seeing color unevenness (ΔY):
A pseudo skin having a diameter of 5 cm was processed in the configuration of Example 1 of JP 2012-217790 A, and a black pseudo stain having a diameter of 5 mm was produced at the center thereof. The spot portion and the non-stain portion were each measured with a color difference meter CM2600D (manufactured by Konica Minolta) to determine the luminance (Y value), and the luminance difference (ΔY) was designed to be 5.
0.02 g of an oily solid cosmetic material was uniformly applied to the entire upper surface of the artificial skin, and the brightness (Y value) of the spot portion and the non-spot portion immediately after application was measured, and the difference (ΔY) was obtained. As this value (ΔY) is smaller, color unevenness is less visible.
