Description

[Technical field]

[0001] The present invention relates to an oily solid composition and a method for producing the oily solid composition. [Background technology]

[0002] The skin develops wrinkles, sagging, pigmentation such as age spots and freckles, etc. due to internal factors such as aging and stress, and external factors such as ultraviolet rays and dry air. In particular, morphological changes such as wrinkles and sagging, and visual changes such as pigmentation, greatly affect the impression of one's appearance, so many people wish to improve them, and a variety of products are available.

[0003] Many active ingredients have been proposed to prevent and improve wrinkles, sagging skin, and pigmentation. Among them, niacinamide, an active ingredient for wrinkles and whitening, is known to be a highly safe ingredient. In addition, the use of tranexamic acid and ascorbic acid glucoside has been proposed as a whitening agent that improves or inhibits pigmentation. However, it is known that when a large amount of active ingredients such as niacinamide, tranexamic acid, and ascorbic acid glucoside are contained, there is an undesirable feeling when used, such as stickiness.

[0004] Various products containing niacinamide, tranexamic acid, and ascorbic acid glucoside as active ingredients have been developed so far. These active ingredients are powdery and water-soluble, and are usually dissolved and mixed in a solvent such as water, so it is difficult to mix them in an oil-based composition that is mainly made of an oil phase or consists of an oil phase. Therefore, there are still few techniques for dispersing and mixing niacinamide, tranexamic acid, and ascorbic acid glucoside uniformly and stably in an oil-based composition. In response to these problems, for example, a technology has been disclosed that provides excellent dispersion stability of tranexamic acid or its derivatives or its salts in an oil-based solid composition containing tranexamic acid or its derivatives or its salts and an acylamino acid ester (e.g., Patent Document 1). Also, for example, a technology has been disclosed that provides uniform dispersion of nicotinamide even in an oil-based topical skin preparation or oil-based cosmetic product containing specific amounts of nicotinamide, liquid oil, oil-based thickener, and silica, even if the content of water-soluble components is small (e.g., Patent Document 2).

[0005] [Patent Document 1] JP 2020-90452 A [Patent Document 2] JP 2019-131538 A Summary of the Invention [Problem to be solved by the invention]

[0006] As mentioned above, there are still few techniques for uniformly and stably blending active ingredients such as niacinamide, tranexamic acid, and ascorbic acid glucoside in an oil phase. However, in contrast to this current situation, the market is in need of oily compositions (oil-based cosmetics or skin topicals) with various functions and usability. In particular, the development of oily solid compositions that can be developed into balms and sticks is being promoted due to their portability and ease of use. Therefore, in order to meet these needs, there is a need for new technological developments for oily solid compositions that maintain uniform dispersion of the active ingredients in the oil phase while achieving stability, functionality, and even good usability. The techniques disclosed in Patent Documents 1 and 2 were sometimes insufficient in terms of the impact resistance of the oily solid composition and the smoothness with which the composition can be applied without ruining makeup.

[0007] Therefore, the present invention aims to develop an oil-based solid composition which maintains uniform dispersion in an oil phase of the powdery, water-soluble active ingredients niacinamide, tranexamic acid, and ascorbic acid glucoside, while exhibiting the impact resistance and smoothness required for an oil-based solid cosmetic or topical skin preparation, and which allows application without ruining makeup.

The average score of all panelists was then calculated and the sample was judged according to the 4-point scale below. The soft focus effect was evaluated by whether applying an oily solid stick could blur the area where it was applied.
