The invention relates to complexes of certain chromone derivatives, to compositions which comprise such derivatives, to corresponding processes for the preparation of the chromone derivatives or of compositions comprising same, and to the use thereof, in particular for the care, maintenance or improvement of the general state of the skin or hair.
摘要:
The invention relates to novel compositions, in particular cosmetic and/or pharmaceutical compositions or food supplements, comprising at least one oxidised flavonoid derivative of the formula I, to novel oxidised flavonoid derivatives, and to novel uses of the oxidised flavonoid derivatives.
摘要:
The invention relates to a cosmetic or dermatological composition containing at least one precursor of a substance whose active form is sought for its cosmetic activity. One of the applications of the invention relates to compositions capable of rapidly imparting to the skin a color similar to that obtained on prolonged exposure to ultraviolet, solar or artificial radiation, while at the same time avoiding the drawbacks of such an exposure (erythema, burning, loss of elasticity, appearance of wrinkles, premature ageing of the skin, and the like).
摘要:
The invention relates to a composition having antioxidant properties comprising at least one compound of the formula I or a cosmetically, dermatologically or pharmacologically tolerated salt or derivative thereof where R1 to R4 can be identical or different and are selected from H C6-28-alkylcarboxylic acid radicals C6-28-alkenylcarboxylic acid radicals radicals of the formula II where R5-R8, independently of one another, are H, hydroxyl or C1-6-alkoxy, with the proviso that at least one of the radicals R1 to R4 is a radical of the formula II.
