Abstract
Abstract Compounds of the general formula ##STR1## wherein two of the residues R 1 , R 2 and R 3 represent C 10-30 -alkyl residues with at least 8 C-atoms in a straight chain, at least one of these residues being substituted by at least 2 C 1-3 -alkyl residues and the sum of the C-atoms in the two residues being greater than 20; and the third residue is a residue --P(O)(O - )OR 4 in which R 4 represents a lower-alkyl or C 5-7 -cycloalkyl residue which is substituted by a quaternary ammonium group or a C 5-7 -cycloalkyl residue which contains a di-(lower-alkyl)-substituted nitrogen atom, are useful for the manufacture of colloidal solution systems. The compounds of formula I can be prepared starting from glycerol derivatives as described in more detail in the specification.
