Hair-treatment compositions which comprise oligoesters prepared by condensation of an aromatic dicarboxylic acid, ethylene glycol and/or propylene glycol and polyethylene glycol and optionally alkylpolyethylene glycol are claimed.

Hair-treatment compositions comprising oligoesters

The present invention relates to a process for the preparation of storage-stable granules essentially comprising a bleaching activator and an inorganic binder material, which comprises the process steps:

Granulated bleaching activators and their preparation

The present invention relates to polycondensates of the general formula I ##STR1## in which X stands, at least once, for a group of the formula VII ##STR2## and, at least once, a group of the formula VIII ##STR3## and the other variables are defined as indicated in claim 1, processes for their preparation and their use.

Polycondensates containing phosphinic or phosphonic acid groups and

The present invention relates to polycondensates of the general formula I ##STR1## in which ##STR2## and the other variables are defined as indicated in claim 1, processes for their preparation and their use.

Polycondensates containing polysiloxane groups

A pulverulant, dry bleach activator, in particular tetraacetylethylenediamine is first moistened with water and then mixed with a dry auxiliary, in particular, with Na carboxymethylcellulose. This mixture is then granulated.
