PYRANONE COMPOUNDS AND SKIN LIGHTENING COSMETIC PREPARATIONS OR LOCAL DEMELANIZING AGENTS CONTAINING THE SAME |
摘要 |
<p>Novel acyl compounds 3-acyloxy-4(H)-pyran-4-ones were obtained by reacting 3-hydroxy-4(H)-pyran-4-one with acyl halides. The acyl compounds and their starting compound exhibit a skin-lightening effect on the skin and are preferably used as an active constituent in skin-lightening cosmetic preparations or local demelanizing agents.</p> |
