Description

  The present invention relates to a hematite extract and a cosmetic containing the same.

  Iron oxide and iron hydroxide have been conventionally used as pigments in cosmetics. For example, iron trioxide is a black pigment with the name of black iron oxide, iron trioxide is a red pigment with the name of Bengala, and iron oxyhydroxide and ferric hydroxide are yellow pigments with the name of yellow iron oxide. It is blended in skin care products, powder products, makeup products, hair care products and the like.

  These iron oxides and iron hydroxides are blended for the purpose of coloring as pigments that are insoluble in water or oils, and there are no examples of blending for other purposes of use.

  The present invention has been made under the circumstances as described above, and provides an extract of hematite obtained from a natural mineral, and further a cosmetic containing the same and expressing a novel function. This is the issue.

  The present invention is a hematite extract obtained from natural ore. The hematite extract of the present invention contains 0.01 to 5.0% by weight of iron sesquioxide as the amount of iron.

  The present invention is also a cosmetic comprising a hematite extract.

  The cosmetic of the present invention is characterized in that the content of the hematite extract is 0.001 to 95.0% by weight.

  The hematite extract of the present invention has an effect of promoting the synthesis of collagen in the skin where it is applied by incorporating it in a cosmetic. This effect has been confirmed, for example, in experiments using human fibroblasts, with the addition of the hematite extract of the present invention, which dramatically increases type I collagen production. This effect is very large compared to TGFβ used as a control. (See Figure 1)

  Since the hematite extract of the present invention also exhibits the red color inherent in hematite, it is also blended as a red colorant.

  Hereinafter, the present invention will be described in detail. The hematite extract of the present invention is a reddish brown aqueous solution obtained by crushing natural ore obtained from a magma layer in a volcanic area, adding water, and extracting, and an iron amount of 0.01 to 5.0. Contains weight percent iron sesquioxide.

  The cosmetic of the present invention contains a hematite extract. The content of this hematite extract varies depending on the type and dosage form of the cosmetic, but is generally 0.001 to 95.0% by weight (hereinafter simply referred to as%), preferably 0.5 to 20. 0%.
