Problems solved by technology

In particular, when silicone oil is included to improve spreading, depending on the type of oil-based component, the compatibility is poor, or the thickening effect or gelling ability is insufficient, so the viscosity of the formulation decreases over time, or the oil component is observed to be separated from the gel. The phenomenon called "drainage" that seeps out of the glue, etc., is rarely effective

Embodiment 1

[0054] Invention products 1-8 and comparative products 1-11: solid paste

[0055] Prepare a solid paste according to the composition shown in Table 1 and Table 2 and the following production method. As an evaluation of the feeling of use, sensory evaluations were performed by panelists on (1) finger pick-up, (2) spreadability, and (3) non-stickiness. The storage stability of the solid paste was left to stand in a thermostat at 50° C. for one month, and changes in appearance (separation, drainage) were evaluated with the naked eye. The results are shown in Table 1 and Table 2 together.

Abstract

The objective is to provide an oily solid-form cosmetic, which exhibits excellent spreadability during use and when applied to the finger, reduced stickiness after application, and excellent storage stability and moisture retention. The oily solid-form cosmetic contains (a) 5-25 wt% of a phospholipid, wherein the phospholipid composition is 25-42% phosphatidylcholine and 25-42% phosphatidylethanolamine, (b) silicone oil having a kinematic viscosity of 1-100 mm2 / s at 25°C, and (c) an ester oil that is liquid at 25°C. The content ratio (b) / (c) of component (b) to component (c) is 0.006-0.4.

Description

technical field [0001] The present invention relates to the phospholipid (ingredient (a)) containing phosphatidylcholine 25~42% of phosphatidylcholine, 25~42% of phosphatidylethanolamine, 25 ℃ having 1~100mm 2 The silicone oil (component (b)) with a kinematic viscosity of / s, the ester oil (component (c)) which is liquid at 25°C, and the content mass ratio (b) / (c) of component (b) and component (c) are: The oil-based solid cosmetics of 0.006 to 0.4, in more detail, relate to oil-based solid cosmetics that are excellent in finger pick-up and spread during use, less sticky after application, excellent in storage stability, and have a high moisturizing effect. Background technique [0002] Phospholipids generally have excellent skin affinity as an ecologically relevant component, and are widely used in the field of cosmetics, especially as dispersants or emulsifiers, moisturizers, and antioxidants (see, for example, Non-Patent Document 1). In addition, silicone oils, especiall...
