摘要:
A preservative and a process for the preparation of a preservative with reduced formaldehyde emission which comprises: a) at least one formal; and b) at least one emission-reducing additive which is selected from urea, urea derivatives, amino acids, guanidine and guanidine derivatives, and wherein the preservative: (i) comprises no iodopropynyl compound; and (ii) no derivative of 1H-benzimidazol-2-carbamic acid.
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. The use solution is preferably in the form of technical and domestic products.
摘要:
A concentrate for cleaning and disinfecting includes (i) one or more alkyl alcohol alkoxylates, (ii) one or more formaldehyde donor compounds, (iii) optionally one or more biocidal, in particular fungicidal, active ingredient(s), (iv) optionally one or more glycols and (v) optionally up to 10% by weight of water. Concentrates according to the invention can be formulated with a high content of formaldehyde donor compound without an undesired formaldehyde odor arising.
摘要:
A microbicidal composition in the form of a concentrate includes a) one or more isothiazolin-3-ones, b) one or more organic amines with an alkyl group having at least 8 carbon atoms and c) one or more oxidizing agents. The concentrate is storage-stable and is used for the preservation of technical and domestic products.

摘要:
An additive mixture for fuels including a) at least one N-formal, b) at least one antioxidant and c) at least one corrosion inhibitor. The additive mixture ensures that the additized fuels and lubricants have biocidal and corrosion-inhibiting additization, especially when they include proportions of renewable raw materials, such as biodiesel, and when they are in contact with copper-containing surfaces.

摘要:
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 C1- to C24-alkyl group, where the alkyl group may be substituted with one or more hydroxy and/or C1- to C4-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 1-10 carbon atoms; (y) an ester of a carboxylic acid having 1-10 carbon atoms; and/or (z) an anhydride of a carboxylic acid having 1-10 carbon atoms. 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 compositions which comprise one or more glycerol ethers together with one or more diol/diols and/or polyol/polyols. 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 regressed to an adequate extent.
