Description

The present invention relates to a solid cosmetic, and more particularly, to a solid cosmetic containing astaxanthin, a partially crosslinked emulsifying silicone elastomer, and a polyhydric alcohol having an IOB value of 1.80 to 3.50. The solid cosmetic of the present invention (hereinafter sometimes referred to as the present solid cosmetic) can effectively apply astaxanthin to the skin, has no stickiness or shine, has excellent moisture retention, and is used before makeup. The present invention relates to a solid cosmetic that does not adversely affect the cosmetic film and does not lose makeup.

Astaxanthin is known for its various effects, such as antioxidant, anti-aging, and whitening, and has been widely used in skin external preparations such as cosmetics and quasi-drugs. Also, various compositions have been developed to further enhance the effect of astaxanthin. Specifically, for example, Patent Document 1 proposes an external preparation for skin that combines an emulsion containing astaxanthin and glycyrrhetinic acid with a specific preservative. As described above, it is generally desirable that ordinary cosmetics and external preparations for skin have excellent spreadability.

However, skin worries such as spots and wrinkles increase with age, but worrisome spots and wrinkle spots occur in different parts of the face, so according to these skin worries Intensive care of the parts of concern is desired.
When such intensive care is performed, it is desirable that the applied cosmetic does not spread excessively and that astaxanthin permeates efficiently at a local site.

For this purpose, for example, as in Patent Document 2, a solid cosmetic containing a wax-type solid oil and a polymer powder is known. However, Patent Document 2 has a feeling that the polymer powder is smoother, and in particular, it is not possible to obtain a sufficient moisturizing property in a portion where wrinkles are generated.

On the other hand, as an astaxanthin-containing solid cosmetic having an excellent moisturizing effect, a technique of blending astaxanthin, a hydrated oil, a solid oil and / or an oil gelling agent (Patent Document 3) has been used. However, Patent Document 3 tends to feel sticky when used before makeup in the morning.
