Description

Foam spray cosmetic

The present invention relates to a foam spray cosmetic, and more specifically to a foam spray cosmetic containing an ultraviolet absorbent.

Protecting the skin from ultraviolet rays is one of the most important issues in skin care, body care, and hair care. In order to minimize the adverse effects of ultraviolet rays on the skin, etc., various UV (ultraviolet) protective cosmetics have been developed. . Sunscreen cosmetic, which is a kind of UV protective cosmetics, blocks UVA and UVB from reaching the skin by preparing ultraviolet absorbers or ultraviolet scattering agents to protect the skin from ultraviolet rays.

Sunscreen cosmetics are currently known: a formulation in which a lotion-like or gel-like cosmetic contained in a container is applied to the skin by hand, a dosage form in which a rod-like cosmetic contained in a container is directly applied to the skin, and Dosage form sprayed directly on the skin. Among them, in terms of being able to obtain a cool feeling at the moment of application during the hot summer period, a foamy spray cosmetic material utilizing the vaporization heat of a liquefied gas is preferred.

As a foam spray cosmetic containing an ultraviolet absorber, for example, Patent Document 1 describes a cosmetic containing a certain amount of coloring pigment, which can naturally correct skin tone and create beautiful skin with transparency.

Further, Patent Literature 2 describes a blistering cosmetic composition containing a water phase, talc and a UV sunscreen component in a medium.

[Problems to be solved by the invention]

In order to spread the sprayed foam, the foam spray cosmetic requires better foam consistency, and in terms of ease of integration with the skin, it requires foamy touch and fine foam when applied. Furthermore, in the sunscreen cosmetics, in order to give full play to the sunscreen effect, it is necessary to formulate corresponding UV absorbers. However, if a large amount of the ultraviolet absorber is blended, the total amount of oil increases, so that the foam quality or foam durability is deteriorated.

The foaming spray cosmetic described in the above-mentioned Patent Document 1 has less preparation of ultraviolet absorbers, has poor foam quality, and has insufficient foam sustainability. In addition, although the foam spray cosmetic described in Patent Document 2 also describes that a large number of ultraviolet absorbers are blended, the foam quality is still poor, and the foam persistence is also insufficient.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a foam-like spray cosmetic material having good foam quality and good foam persistence even if there are many formulations of ultraviolet absorbers.
