Description

Description: TECHNICAL FIELD The present invention relates to an external or head cosmetic composition containing hydrotalcite, and more particularly, to cosmetics, excellent usability, sweat and skin waste. A skin external cosmetic that excels in improving skin roughness because it absorbs sebum wastes and body odors, suppresses inflammation due to acne, etc., excels in eliminating body odor, and hair skin that excels in suppressing scalp itch and hair odor Related to external cosmetics.

[Prior art] Because cosmetics are an important function for cosmetics,
Many studies have been made conventionally. For example,
There is a method of blending volatile oils and then evaporating the oils after makeup to improve makeup, and a method of improving makeup with oil-in-water type emulsifying base. There are sebum, sweat, physical friction, etc. Is not complete because the problem has complex consequences. There is also a method of blending waxes, but they have disadvantages such as oiliness and weight of growth characteristic of waxes. In addition, various chemicals have been conventionally added to cosmetics for the purpose of improving rough skin and suppressing inflammation due to acne, but a sufficient effect has not yet been obtained.

On the other hand, bactericides and chemicals have been conventionally added to hair cosmetics for the purpose of preventing itching and hair odor due to waste products of the scalp, but there are problems with safety and sufficient effects have been obtained. It is not at present.

[Problems to be Solved by the Invention] The present invention has been made in view of the problems of the prior art described above, and its object is to have makeup, excellent usability, sweat, skin waste, sebum waste, body odor and the like. It is an object of the present invention is to obtain a cosmetic composition for external use on the skin which is excellent in the effect of improving skin roughness and suppressing inflammation due to acne and the like, and a cosmetic composition for the head which is excellent in the effect of suppressing scalp itch and eliminating hair odor.

[Means for Solving the Problems] That is, the present invention is a cosmetic for external use on the skin or a cosmetic for the head, comprising hydrotalcite.
