摘要:
The invention relates to a liquid concentrate for the preservation of cosmetic and pharmaceutical products based on 3-iodo-2-propynyl butylcarbamate (IPBC) which, in addition to IPBC, comprises a liquid carrier chosen from polyvalent alcohols, glycol esters and glycol ethers or any mixture thereof and a stabilizer chosen from formic acid, formic acid salts and formate esters or any mixture thereof, no additional carboxylic acid chosen from benzoic acid, propionic acid, salicylic acid, sorbic acid, 4-hydroxybenzoic acid, dehydroacetic acid and 10-undecylenic acid or a salt thereof being present.
摘要:
The invention relates to microbicidal preparations which comprise a) at least one of 1,2-benzisothiazolin-3-one and its derivatives, b) at least one of 2-mercaptopyridine N-oxide, its salts and derivatives and c) at least one alkalinizing agent, or which are prepared by mixing components a) to c), where the preparations have a pH of at least 11. The preparations are characterized by the fact that they are clear and storage-stable, and they are suitable for use as preservatives.
摘要:
Cooling lubricant (concentrate or solution) comprising a cooling lubricant base based on mineral and/or synthetic oil and preservative comprising (a) one or more 1- or 2-(C 3 to C 24 alkyl) glyceryl ethers.
摘要:
The invention relates to a microbicidal use solution which comprises a) one or more isothiazolin-3-ones and b) one or two organic amines selected from N-dodecylpropane - 1,3 - diamine and bis (aminopropyl) - dodecylamine and optionally c) one or more oxidizing agents.

摘要:
The invention relates to compositions which comprise 1-(2-ethylhexyl) glycerol ether with 1,2-octanediol. As a result, as well as good microbicidal effectiveness, whitening is reduced or avoided, drying-out of the skin is prevented, the moisture content is regulated and the skin is regreased to an adequate extent.
摘要:
The present invention relates to compositions, which comprise a working solution characterized in that the composition comprises a combination: a) 20% to 60% by weight of 3-[(2-ethylhexyl)oxy]-1,2- propanediol with, b) an antioxidant chosen from vitamin E and its derivatives, 3-tert-butyl-4-hydroxyanisole and 2,6 di-ter-butyl-p-cresol, preferably vitamin E and vitamin E acetate,
the simultaneous presence of phosphocholines and phosphocholine derivatives being excluded.
摘要:
The invention relates to a process for the preparation of a 1-alkyl glycerol ether of the formula (I)
in which (a) an alkyl glycidyl ether of the formula (II)
in which R is an unbranched or branched C 1 - to C 24 -alkyl group, where the alkyl group may be substituted with one or more hydroxy and/or C 1 - to C 4 -alkoxy group(s) and/or the alkyl chain may be interrupted by up to four oxygen atoms, is added to (x) a carboxylic acid having 1 to 10 carbon atoms, (y) an ester of a carboxylic acid having 1 to 10 carbon atoms and/or (z) an anhydride of a carboxylic acid having 1 to 10 carbon atoms
and the low-water reaction mixture containing a catalytic amount of a strong acid is reacted at a temperature of more than 40°C to give an acylated alkyl glycerol ether, and (b) the acylated alkyl glycerol ether is reacted in order to obtain the alkyl glycerol ether of the formula (I).
摘要:
The invention relates to a microbicidal composition which comprises a) at least one formaldehyde donor compound and b) at least one antioxidant chosen from gallic esters, phenol derivatives, L-ascorbic acid, and salts and derivatives thereof, and tocopherols and derivatives thereof, and to the use thereof for the preservation of technical products, for example fuels and lubricants.
摘要:
Use of a composition which contains (a) one or more 1-or 2-(C 3 to C 24 -alkyl)glycerol ethers and (b) one or more aromatic alcohols for the disinfection of the surface of an article at a temperature above 25°C.
