摘要:
L'invention concerne un procédé de production d'hydrogène d'hydrogène, de monoxyde de carbone ou d'un mélange H 2 /CO obtenu par reformage à la vapeur à partir d'un mélange d'hydrocarbures légers comprenant une étape de génération de gaz de synthèse par reformage de méthane à la vapeur via une unité de reformage, dans lequel au moins un équipement alimenté en électricité est essentiel au fonctionnement de l'unité de reformage, caractérisé en ce que en cas de perturbation de la fourniture d'électricité, chacun desdits équipements alimentés en électricité essentiels au fonctionnement de l'unité de reformage est alimenté en électricité instantanément, sans limitation de durée et sans interruption via un système dédié de sorte que ladite perturbation de la fourniture d'électricité ne provoque pas l'interruption de la production de gaz de synthèse et de la production du produit final obtenu à partir de celui-ci.
摘要:
A description is given according to the invention of a composition on an aqueous basis which comprises a) 0.001 to 10% by weight bispyridinium alkane, b) 0.1 to 30% by weight nonionic surfactant, c) 0 to 40% by weight aromatic alcohol and d) 0.01 to 10% by weight polyol selected from alkanediols and alkanetriols. The compositions, as mouthwash solutions, are more active than current commercial products and are distinguished by a pleasant taste and low tendency to foaming.
摘要:
Composition characterized in that, it consists of, for 100 weight %: a) From 1 weight % to 10 weight % of at least one of 1,2-benzisothiazolin-3one and its derivatives, b) From 0.5 weight % to 5 weight % of at least one of 2-mercaptopyridine N-oxide, its salts and its derivatives c) From 1 weight % to 6 weight % of N,N-bis(3-amino propyl)-dodecylamine d) At least one alkalinizing agent, in a concentration such that the pH is greater than 11, and e) Water up to 100 weight %; the process for its preparation and its as an additive of technical products.
摘要:
Disclosed is a liquid concentrate which includes a) one or more aromatic alcohols, b) one or more specific organic acids or salts thereof and c) octenidine dihydrochloride. The liquid concentrate is used for preserving pharmaceutical (primarily dermatological) or cosmetic products.
摘要:
The invention relates to antimicrobial compositions which contain (i) at least one zinc compound selected from zinc salt and zinc oxide, (ii) at least one glycerine monoalkyl ether of the general formula €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R-O-CH 2 -CHOH-CH 2 OH, wherein R is a branched or unbranched C 1 -C 24 alkyl group, wherein the alkyl group can be substituted with one or more hydroxy and/or C 1 -C 4 alkoxy group(s) and/or the alkyl chain can be interrupted by up to four oxygen atoms, (iii) at least one antioxidant and optionally (iv) one or more alkanediols, wherein the weight ratio (w/w) of component (ii) to component (iii) is at least 10:1. The compositions are used in cosmetic and pharmaceutical products and already have broad antimicrobial activity, in particular against Pseudomonas aeruginosa, at active substance contents of only about 3 wt.%.
摘要:
The invention relates to a method for determining the cleaning performance of a formulation. In the method a) the formulation is provided, b) a test body is brought into contact with the formulation, the test body being contaminated with a protein-containing test contaminant, c) the contaminated test body is left in contact with the formulation in order to clean the contaminated test body, d) the cleaned test body is rinsed, e) if necessary the rinsed test body is dried, f) if necessary the test contaminant remaining on the test body is evaluated in terms of quality and g) the test contaminant remaining on the test body is analysed in terms of quantity, the quantitative analysis of the remaining test contaminant including the removal of the remaining test contaminant from the test body. By means of the method the evaluation of the cleaning performance of formulations for the machine cleaning of hard surfaces, in particular medical devices, is made easier, in particular with regard to protein-containing contaminants.
