摘要:
Compositions having broad effectiveness against bacteria and fungi, which comprise (a) an iodopropynylbutyl compound and (b) one or more formaldehyde donor compounds, the formaldehyde donor compounds being N-formals, O-formals and/or a combination thereof. The compositions are also stable and effective in the form of liquid concentrates. The present invention also relates to the use of such compositions in industrial products and to industrial products which comprise these compositions.
摘要:
2-Benzylideneglutaraldehydes of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 independently are hydrogen or a substituent selected from the group consisting of halo, lower-alkyl, phenyl, carboxy, lower-alkoxycarbonyl, phenoxycarbonyl, aminocarbonyl, hydroxysulfonyl, nitro, cyano, hydroxy, lower-alkoxy and phenoxy, a method of use thereof as disinfectants, disinfectant compositions comprising them, and 2,6-dialkoxy-3-(.alpha.-alkoxybenzyl)tetrahydropyrans of the formula ##STR2## where R.sup.1, R.sup.2 and R.sup.3 are as defined above and R.sup.4 and R.sup.5 independently are alkyl of one to four carbon atoms, which are intermediates for their preparation are disclosed.
摘要:
There is disclosed a method for controlling bacteria, fungi and spores which comprises applying thereto a 2,5-disubstituted-di (or tetra) hydrofuran, a process for preparation of such furans, and the novel compound 2,5-bis (benzyloxy) tetrahydrofuran.
摘要:
There is disclosed a method for controlling bacteria, fungi and spores which comprises applying thereto a bactericidally, fungicidally and sporicidally effective amount of a furan selected from 2-(R.sub.1 O)-5-(R.sub.2 O)-2,5-dihydrofuran and 2-(R.sub.1 O)-5-(R.sub.2 O)-tetrahydrofuran or mixtures thereof; a process for preparing a 2,5-bis(R.sub.1 O)-2,5-tetrahydrofuran and 2,5-bis(R.sub.1 O)-tetrahydrofuran; and novel 2,5-bis(benzyloxy)tetrahydrofuran.
摘要:
An aqueous-based composition which includes a) at least one bispyridinium alkane (for example octenidine) and b) at least one stabilizer selected from antioxidants, complexing agents, reducing agents, UV filters and photoprotective agents, in particular α-tocopherol, and BHT. The composition can also include c) one or more auxiliaries selected from, for example, nonionic surfactants, ethers, solvents and polymers, in particular fatty alcohol alkoxylates and alkoxylated fatty acid monoglycerides. The presence of the stabilizer reduces or prevents the appearance of decomposition products of bispyridinium alkanes and, in the case of the presence of auxiliaries, of decomposition products of the auxiliaries, such as ethers and peroxides.
摘要:
The invention relates to disinfectant compositions which include one or more 1- or 2-(C1- to C24-alkyl)glycerol ethers (glycerol monoalkyl ethers), one or more bispyridiniumalkanes and where appropriate one or more polyols and/or one or more surfactants selected from the group of c1) nonionic surfactant and c2) quaternary ammonium compound, and to the use of the compositions for hygienic hand disinfection or for disinfectant handwashing, and as skin antiseptic. The compositions according to the invention have a particularly low surface tension and thus an improved wetting effect.
