摘要:
Process for stabilizing polymerizable compounds to polymerization during working-up, storage and/or transport, in which at least one free radical scavenger which contains at least two glycine units is used, with the proviso that the free radical scavenger is not selected from ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), trans-1,2-cyclohexanediaminetetraacetic acid (CYDTA) and the alkali metal and alkaline earth metal salts thereof.
摘要:
A process for preparing and/or working up mixtures by (meth)acrylic acid and/or (meth)acrylic ester in the presence of at least one polymerization inhibitor and at least one oxygenous gas, which comprises metering in at least part of the oxygenous gas at an exit rate of at least 50 mm/s.

摘要:
The invention relates to cosmetic or dermatological preparations that arc characterized by having a content of: a) at least one antioxidant that acts as an 0- or C-radical scavenger, and; b) at least one organic, boron-containing compound that reduces the peroxides or hydroperoxides to the corresponding alcohols without forming active radical subsequent stages.
摘要:
Printing inks for offset and/or letterpress printing which comprise NIR absorbers, and solubility of the NIR absorber in the printing ink is at least 0.1% by weight. NIR absorbers consisting of cyanine cation with an anion which has long-chain alkyl or aralkyl groups. Use of such printing inks for printing processes in which the curing of the printing ink is promoted by using IR lasers. NIR absorbers comprising a cyanine cation with an anion which has long-chain alkyl or aralkyl groups.

摘要:
The present invention relates to dermocosmetic compositions comprising a compound comprising the structural element of the formula I where the radical Z has the following meaning: H, C1-C22alkyl group, C6-C10-aryl group, C1-C22-alkoxy group or a C6-C10-O-aryl group substituted by a C1-C22-alkyl or C-C22-alkoxy group,and the radicals R1 to R6, independently of one another, have the following meaning: H, C1-C22-alkyl group, C6-C10-aryl group, O, OH, C1-C22-alkoxy group or a C6-C10-O-aryl group substituted by a C1-C22-alkyl or C1-C22-alkoxy group,it being possible for R5 and R6 to be bridged in such a way that a five- to eight-membered ring is formed and, in the case of a five-membered ring, this ring may be part of an oligomer as a result of covalent bonds at positions 3 and 4.The invention furthermore relates to the use of said compounds in dermocosmetic formulations and the use of the dermocosmetics according to the invention for reducing skin or hair damage caused by free radicals. The invention furthermore relates to the use of the compounds according to the invention for increasing the stability of dermocosmetic formulations.
