Title: Improvements in or relating to preserving and disinfecting agents
IPC: A01N37/04
Filed: 1937-06-17
Abstract: A preserving or disinfecting composition comprises an active preservative or disinfectant of aromatic character, other than benzene, together with an emulsifying and wetting agent consisting of a condensation product, of the type described in Specification 493,442, formed from a succinic acid anhydride containing in one methylene group a substituent having at least 5 carbon atoms, and a tertiary amino compound containing, in addition to the tertiary amino group, a hydroxyl or primary or secondary amino group which is capable of forming a functional derivative with one of the acid carboxyl groups.  Preservatives and disinfectants specified are phenol, tri- and tetra-chlor phenols, chlorinated cresols and xylenols, hydroxybenzoic acids and naphthalene.  According to examples: (1) a solution of trichlorophenol in the condensation product of iso - pentadecenyl - succinic acid anhydride with triethanol-amine is used for preserving glue; (2) monochlor-xylenol and naphthalene dissolved in iso-nonenyl-succinic acid-mono-b -N-diethylaminoethylamide is used for preserving starch, gums and the like; (3) an aqueous solution of monochloro-cresol, isooctadecenyl-succinic acid - mono - b  - N - diethylamino-ethyl ester, and poly-glycol ether is added to a salt pickle for preserving skins.  Other condensation products are those prepared from iso-nonenyl, iso- or n-dodecenyl succinic acid anhydrides, or from the addition products of mono-, di- or tri-isopropyl benzene or iso-propyl naphthalene to maleic anhydride, with tertiary amino compounds such as diethyl-amino-ethyl alcohol, b -N-hydroxyethyl-morpholine, N.N - diethylethylene - diamine, and N.N.N1 - triethylethylene - diamine.  The Provisional Specification is not limited to the use of aromatic substances as the active preservatives or disinfectants, but contains no additional examples.ALSO:A preserving or disinfecting composition comprises an active preservative or disinfectant of aromatic character, other than benzene, together with an emulsifying and wetting agent consisting of a condensation product, of the type described in Specification 493,442, [Group IV], formed from a succinic acid anhydride containing in one methylene group a substituent having at least 5 carbon atoms, and a tertiary amino compound containing, in addition to the tertiary amino group, a hydroxyl or primary or secondary amino group which is capable of forming a functional derivative with one of the acid carboxyl groups.
