摘要:
The invention relates to compounds of the formula (I) or (II), to compositions which comprise such compounds, to corresponding processes for the preparation of the compounds or the compositions comprising same, and to the use thereof as light-protection filters.
摘要:
The invention relates to a preparation having light-protection properties comprising at least one compound of the formula I where R1 and R2 are selected from H and OR11, where each OR11, independently of the others, is OH, a straight-chain or branched C1- to C20-alkoxy group, a straight-chain or branched C3- to C20-alkenyloxy group, a straight-chain or branched C1- to C20-hydroxyalkoxy group, where the hydroxyl group(s) may be bonded to a primary or secondary carbon atom in the chain and furthermore the alkyl chain may also be interrupted by oxygen, and/or a C3- to C10-cycloalkoxy group and/or C3- to C12-cyclo-alkenyloxy group, where the rings may each also be bridged by —(CH2)n— groups, where n=1 to 3, and/or a mono- and/or oligoglycosyl radical, with the proviso that at least one radical from R1 and R2 is OR11, and R3 is a radical OR11, and R4 to R7 and R10 may be identical or different and are, independently of one another, radicals which are substantially inert with respect to the UV properties.
摘要:
The present invention relates to formulations for topical applications comprising pigments obtainable by agitating a suspension comprising one or more inorganic pigments and silver oxide, in order to reduce undesirable side effects caused by microorganisms.
摘要:
The present invention relates to novel compositions containing ascorbic acid with an increased bioavailability of this vitamin. These compositions are useful as food supplements possessing preventive properties against damages of human organs, including skin, tissues and cells due to oxidative stress or damages.
摘要:
The invention relates to a cosmetic or pharmaceutical formulation comprising at least one compound of formula (I). The cosmetics or pharmaceutical products are particularly suitable for the care of the skin in protecting against oxidative stress and ageing phenomena.
摘要:
The invention relates to the use of chrome-4-one derivatives of the formula I where R1 and R2 may be identical or different and are selected from H, —C(═O)—R7, —C(═O)—OR7, alkyl groups, alkenyl groups, hydroxyalkyl groups and/or cycloalkyl groups and/or cycloalkenyl groups, R3 is H or alkyl groups, R4 is H or OR8, R5 and R6 are selected from —H, —OH, alkyl groups, alkenyl groups and hydroxyalkyl groups, and R7 is H, alkyl groups, a polyhydroxyl compound, such as, preferably, an ascorbic acid radical or glycosidic radicals, and R8 is H or alkyl groups, where at least two of the substituents R1, R2 and R4—R6 are different from H or at least one substituent from R1 and R2 is —C(═O)—R7 or —C(═O)—OR7, for the care, preservation or improvement of the general state of the skin or hair.
摘要:
Disclosed is a method for producing compounds of formula (I), wherein R1 represents H or (CH2)mOH, R2 represents H or (CH2)nOH, R3 represents H or (CH2)pOH and m, n and p represent 2-8 independently from one another. Said compounds are particularly suitable for use as food supplements. They are highly suitable for use in cosmetic formulations as UV filters, for instance.
摘要:
The invention relates to the use of at least one ascorbic acid derivative for the fictionalization of matrices, and to specific ascorbic acid derivatives and processes for the preparation thereof.
摘要:
The present invention relates to an opto-electronic device comprising a first layer and a second layer on a substrate, characterized in that the first layer comprises an electrode material containing fluorine-containing groups and the second layer comprises a polymer containing fluorine-containing groups, where an adhesive fluorine-fluorine interaction exists between some of the fluorine-containing groups of the first layer and of the second layer. The invention furthermore relates to the use of the opto-electronic device and to a process for the production of the opto-electronic device according to the invention.
