  • Patent number: 6583105
    Abstract: The invention 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 (b) a quaternary ammonium compound of the formula  in which R1 and R2 independently of one another are C1-C5alkyl; or hydroxy-C1-C5alkyl; A and B are a C8-C20 fatty acid radical; the radical of the formula  or the radical of the formula B is C1-C5alkyl; a C8-C20 fatty acid radical; the radical of the formula (1a) or the radical of the formula (1b); R3, R4 and R5 independently of one another are a C8-C20 fatty acid radical; X1− is a softener-compatible anion; and m, n and p are numbers from 0 to 5. The novel composition is used to obtain good bleaching effects on soiled textile fabrics.

  • Patent number: 4876333
    Abstract: A crystalline modification, designated ".beta.", of the dye of the structure ##STR1## The .beta.-crystalline modification of the dye is easier to isolate from water and gives filter cakes of higher solids and color content. The .beta.-form is also more suitable for making liquid formulations of the dye; the liquid formulations of the crystalline modification have lower viscosity and better dispersion stability than liquid formulations of non-modified form. The .beta.-modification of the dye is obtained by heating an aqueous slurry of the dye at about 90.degree.-95.degree. C. and pH of 8.5 to 9.5 until the modification is complete. The crystalline modification of the dye gives Debye-Scherrer X-ray diffraction patterns substantially different from the non-modified form.
