Abstract: Aqueous acidic bleaching compositions are described which comprise hydrogen peroxide and a specific class of surfactants which stabilize hydrogen peroxide.

Abstract: This invention relates to imido-derivative peroxycarboxylic acids having the formula I: ##STR1## wherein R and R.sub.1, which may be the same or different, represent hydrogen atoms, alkyl groups, or, taken together with the carbon atoms to which they are linked, give rise to a cyclic aliphatic ring, all of them being optionally substituted; the . . . symbol indicates a simple or an olefinic bond; R.sub.2 represents a hydrogen atom, an alkyl group, or an OH group, and n is an integer different from 0; the process for their preparation and their use as bleaching agents.

Abstract: Mildly acidic multi-purpose liquid cleaning compositions which comprise a specific nonionic surfactant system are disclosed. The nonionic surfactant system comprises at least four different nonionic surfactants belonging to four different HLB classes. The compositions can be used for laundering, hard surface cleaning for bathrooms, kitchens or floors, as well as for cleaning carpets.

Abstract: Disclosed are 2-aza-substituted 1-carbadethiapen-2-em-3-carboxylic acids I, where the generic 2-aza group includes azido, acylamino, amino, alkylamino, dialkylamino, triazolyl, triazolinyl, aziridinyl, and their pharmaceutically acceptable salt, ester, anhydride and amide derivatives which are useful as antibiotics. Also disclosed are processes for the preparation of 1 from the known, appropriately substituted bicyclic keto ester II via the 2-azido central intermediate III: ##STR1## wherein R.sup.16 is H or CH.sub.3, preferably beta-methyl; R.sup.6, and R.sup.7 are independently hydrogen, linear, branched or cyclic C.sub.1 -C.sub.5 alkyl, which can be substituted with fluoro, hydroxy, protected hydroxy, sulfoxy, amino, protected amino, wherein R.sup.6 and R.sup.7 taken together can also be C.sub.2 -C.sub.4 alkylidene, similarly substituted; with the proviso that both R.sup.6 and R.sup.7 are not unsubstituted alkyl, R.sup.1 and R.sup.
