Abstract: A novel motilin analog peptide containing leucine instead of the usual 13th amino acid methionine, as in the naturally occurring motilin, is produced by gene recombination techniques in which several or identical genes, each coding for the novel peptide, are joined in series into a vector. The resultant recombinant DNA is introduced into Escherichia coli and the resultant transformant is cultivated. The resulting polymeric peptide can be cleaved to give the desired peptide.

Abstract: A melanin-coated pigment obtained by coating a carrier with a readily alkali-soluble natural melanin, and a cosmetic containing the pigment are provided. The melanin-coated pigment is highly safe and has high coloring and high saturation tone, and a cosmetic which contains it is also expected to have ultraviolet-ray-absorbing and anti-oxidizing effects.

Abstract: Disclosed is a cosmetic composition comprising N-acetylglutamine or a salt thereof.The cosmetic composition of the present invention which is excellent in feel and stability is effective in retaining moisture in the stratum corneum.
