The present invention relates to a process for separation of oxyresveratrol molecule from the extracted solution of Artocarpus lakoocha Roxb. through membrane application. The product can be obtained in excellent yield upto 81% in case of extraction using water as solvent and can be separated from the extracted mixture upto 98% using indigenously developed nanofiltration membrane. Only the desired Trans isomer is obtained and no cis isomerization takes place during the extraction process.
The hair cosmetic composition of the present invention, which is a one-agent type or a multi-agent type hair cosmetic composition, contains, the following components (A) to (D), the component (C) content, relative to the total composition of the hair cosmetic composition, being 0.1 mass % or higher and lower than 20 mass %:
(A): a compound selected from the group consisting of glyoxylic acid, a glyoxylic acid hydrate, a glyoxylate salt, and a glyoxylamide;
(B): a phenolic compound having an electron-donating group on at least one m-position and having a hydrogen atom on at least one of the o-positions and the p-position, wherein the electron-donating group on the m-position may form, together with an adjacent carbon atom, a benzene ring optionally substituted with hydroxyl group(s);
(C): an organic solvent having a boiling point of 100° C. or higher; and
(D): water.
