- or compounds of the general formula (IV): ##STR5## wherein: each X is, independently, a C.sub.1-8 -alkylene radicals, C.sub.2-8 -alkenylene radicals or aromatic rings, and
- Y is a C.sub.1-8 alkylene radical, C.sub.2-4 -alkenylene radical, O, S or a C--C single bond, or salts thereof.
- 2. The method as claimed in claim 1, wherein in formula (I) n has the value 0, the radical R.sup.1 is a C.sub.6-14 -hydrocarbyl radical or -hydroxyhydrocarbyl radical, and the radical R.sup.2 is a C.sub.1-5 -hydrocarbyl radical.
- 3. The method as claimed in claim 1, where the textile detergent composition comprises at least one bleach and at least one bleach activator, with or without a bleach stabilizer and with or without other bleach catalysts.
- 4. The method as claimed in claim 1, where the textile detergent composition comprises at least one enzyme.
- 5. The method as claimed in claim 1, for bleaching hydrophobic stains on textiles.
- 6. The method as claimed in claim 1, wherein the bleaching or washing temperature does not exceed 40.degree. C.
- 7. A bleach or textile detergent composition, comprising:
- (a) 0.5-40% by weight of bleach in the form of peroxy compounds and/or percarboxylic acids,
- (b) 0-20% by weight of bleach activators, and
- (c) 0.1-1.0% by weight of secondary amines as defined in claim 2.
- 8. A bleach or textile detergent composition, comprising:
- (a) 0.5-40% by weight of bleach in the form of peroxy compounds and/or percarboxylic acids,
- (b) 0.1-20% by weight of at least one bleach activator selected from the group consisting of tetraacetylethylenediamine (TAED), NOBS, isoNOBS, carbonylbiscaprolactam, benzoylcaprolactam, bis(2-propylimino) carbonate, bis(cyclohexylimino) carbonate, acetone O-benzoyloxime, anthranil, phenylanthranil, N-methylmorpholinoacetonitrile, N-methylpiperazine-N,N'-diacetonitrile and N-octanoylcaprolactam (OCL), and
- (c) more than 0.1 to less than 1.0% by weight of secondary amines as defined in claim 1.
- 9. A bleach or textile detergent composition, comprising:
- (a) 0.5-40% by weight of at least one bleach selected from the group consisting of sodium perforates, sodium carbonate perhydrates, C.sub.1-C.sub.12 -percarboxylic acids, C.sub.8 -C.sub.16 -dipercarboxylic acids, imidopercaproic acids and aryldipercaproic acids,
- (b) 0-20% by weight of bleach activators and
- (c) more than 0.1 to less than 1.0% by weight of secondary amines as defined in claim 1.
- 10. A bleach or textile detergent composition, comprising:
- (a) 0.5-40% by weight of bleach in the form of peroxy compounds and/or percarboxylic acids,
- (b) 0-20% by weight of bleach activators, and
- (c) 0.1 to less than 0.5% by weight of secondary amines as defined in claim 1.
- 11. A bleach or textile detergent composition, comprising:
- (a) 0.5-40% by weight of bleach in the form of peroxy compounds and/or percarboxylic acids,
- (b) 0-20% by weight of bleach activators, and
- (c) 0.01-5 of secondary amines as defined in claim 1.
