ABSTRACT:

The present invention relates to a fabric softener composition and to a process for the bleaching of textile fibre materials using this fabric softener composition.
In customary household washing processes for whites, such as bed linen, table linen and white cotton fabrics, the laundry items to be treated are normally subjected to a combined washing and bleaching process in which the items of laundry are treated in an aqueous bath comprising, as active substance, an organic detergent and a bleach. Processes for bleaching or removing stains from textiles using water-soluble phthalocyanine compounds are known, for example, from U.S. Pat. Nos. 3,927,967, 4,094,806 and 4,033,718.
The object of the present invention is to use water-soluble phthalocyanine compounds as photobleaching agents in certain fabric softener compositions comprising, as active substance, ester quats, which are quaternary ammonium compounds having at least one long-chain hydrophobic alkyl or alkenyl group interrupted by carboxyl groups. Fabric softeners containing ester quats are described, for example, in EP-A-0 239 910 or WO 95/24460.
Surprisingly, it has now been found that fabric softener compositions comprising water-soluble phthalocyanine compounds of a cationic, neutral or anionic nature bring about particularly good bleaching effects if textiles are treated in an aqueous fabric softener bath comprising these compositions, the textiles being irradiated with light in the visible and/or infrared region or in the daylight in the fabric softener bath itself or subsequently in the damp state.
The present invention thus relates to a fabric softener composition comprising
(a) a water-soluble phthalocyanine of Zn, Fe(II), Ca, Mg, Na, K, Al, Si(IV), P(V), Ti(IV), Ge(IV), Cr(VI), Ga(III), Zr(IV), In(III), Sn(IV) or Hf(VI); and

s
−
to compensate the positive charge; where, when r≠1, the radicals Q
1
can be identical or different,
and where the phthalocyanine ring system may also comprise further solublising groups.
The number of substituents Q
1
and Q
2
in the formula (2a) and (2b) respectively, which may be identical or different, is between 1 and 8, and it is not imperative, as is generally the case with phthalocyanines, for it to be an integer (degree of substitution). If other noncationic substituents are present, the sum of the latter and the cationic substituents is between 1 and 4. The minimum number of substituents which must be present in the molecule is governed by the solubility of the resulting molecule in water. It is sufficiently soluble in water when enough of the phthalocyanine compound dissolves to effect a photodynamically catalysed oxidation on the fibre. A solubility as low as 0.01 mg/l may suffice, although one of from 0.001 to 1 g/l is generally advantageous.
Halogen means fluorine, bromine or, in particular, chlorine.
Especially suitable groups
are:
Preference is given to the group
Suitable heterocyclic rings in the group
are likewise the groups listed above, the bond to the other substituents merely being via a carbon atom.
In all of these substituents, phenyl, naphthyl and aromatic hetero rings may be substituted by one or two further radicals, for example by C
