ABSTRACT:
The present invention relates to quaternized polyamidoamines which have at least one structural unit of the formula VIIin whichR1, R2, R4are straight-chain or branched organic radicals optionally containing heteroatoms;R5is hydrogen or alkyl,R7is hydrogen or alkyl or two radicals R7together form a radical having a meaning given for R4,b is an integer from 0 to 50, andc is an integer from 1 to 50.The invention also relates to the preparation of the quaternary polyamidoamines, to compositions which comprise these compounds, and to the use thereof for cosmetic and pharmaceutical purposes, and in the fields of crop protection and textile dyeing. The present invention also relates to the use of quaternized polyamidoamines of the ionene type as biostatic or biocide and thus also biocidal compositions based on quaternized polyamidoamines.
