Abstract: Compounds of the formula I ##STR1## in which X denotes a hydrogen atom, a group which irreversibly masks the terminal amino group, or a protecting group which is conventional in peptide chemistry, such as, for example, Boc-, Z- or Fmoc-,A and B may be identical or different and denote an alpha- beta- or gamma-amino acid which comprises 2 to 15 carbon atoms and up to 4 nitrogen atoms, 2 sulfur atoms and 6 oxygen atoms and whose side chain may be substituted, and B, if appropriate, denotes a dipeptide formed from these amino acids,C denotes arginine, Lysine, tyrosine, phenylalanine or tryptophane, and their homologs,R.sub.1 and R.sub.2 are identical or different and denote a hydrogen atom or an alkyl radical having up to 4 carbon atoms,R.sub.3 to R.sub.8 are identical or different and denote hydrogen, an alkyl radical, an alkoxy radical or a halogen radical,Y denotes oxygen, andAn.sup.- denotes an anion, and their water-soluble salts, and a process for their preparation are described.

Abstract: The invention relates to mixtures of nitrogen-containing surface-active agents which are obtained by esterification of oxyalkylates based on modified or nonmodified naturally occurring resin acids or resin amines or resin alcohols derived therefrom with dicarboxylic acids or anhydrides thereof and subsequent reaction with alkylenediamines or alkylenepolyamines. These nitrogen-containing surface-active agents are suitable as coupling auxiliaries, emulsifiers, dispersing agents, preparation agents for solids dispersions, corrosion protection and metal-working agents and as wetting agents and dyeing auxiliaries.

Abstract: Polymeric, water-soluble triazine compounds which contain both basic and acidic groups in the molecule have out-standing surfactant properties and are suitable for the preparation of dispersions of solids, preferably of dispersions of inorganic and/or organic pigments, in an aqueous or water-dilutable medium. Since these triazine compounds are colorless or only slightly colored, they do not influence the shade of the medium used.
