  • Publication number: 20240034962
    Abstract: The present invention concerns a granule comprising Mn(II) oxalate, a protonated salt of a cyclic triamine, a polysaccharide absorbent and a coating agent. In another embodiment the invention concerns a granule comprising a polysaccharide absorbent, a protonated salt of a cyclic triamine and no or very small amounts of Mn. The invention also concerns methods of preparing said granules comprising Mn(II) oxalate, polysaccharide absorbent and such salts or comprising polysaccharide absorbent, such salts and no Mn compound and bleaching formulations comprising the granules and a peroxy compound or a precursor thereof. Granules comprising Mn(II) oxalate, polysaccharide absorbent and the salt or comprising polysaccharide absorbent, the salt and no Mn compound, and formulations comprising these are suitable for use in catalysing oxidation, for example as a component of a dishwasher bleaching composition. The invention further relates to methods of oxidising with the bleaching formulations described herein.

  • Publication number: 20230406999
    Abstract: Disclosed are polyesters containing structural units corresponding to formula (I) or to formula (II) or to formulae (I) and (II), structural units of formula (III) or of formula (IV) or of formulae (III) and (IV), and optionally structural units of the formula (V) —CO—R1—CO—O—C2H4—O—??(I), —CO—R1—CO—O—(C3H6—O)—??(II), —CO—R2—CO—O—C2H4—O—??(III), —CO—R2—CO—O—(C3H6—O)—??(IV), —CO—R3—CO—O—R4—O—??(V), as well as nonionic endgroups of the formula (VI), and optionally nonionic endgroups of the formula (VII) —CO—(O—C2H4—)n—OR5??(VI), —CO—OR6??(VII). In these structural units and endgroups R1 to R6 are selected organic radicals and n is a number between 30 and 500. The polyesters according to the invention are characterized by very good soil release properties, can be readily stored in detergent and cleaning agent formulations and can be used as soil-release polymers.

  • Patent number: 11208372
    Abstract: Disclosed are compounds of formula (I) (R1OOC)a—R2(OH)c—COO—(CnH2n—O)m—OC—R3(OH)d—(COOR4)b??(I) wherein R1 and R4 independently of one another are hydrogen, a metal cation, an ammonium cation, C1-C6-alkyl, cycloalkyl with three to nine ring carbon atoms, aryl with five to ten ring carbon atoms, aryl that is substituted with one or two alkyl groups, aryl that is connected via an alkylene group with the carboxyl group, —(CnH2n—O)m—H or —O—R2(COOR1)a+1, R2 and R3 independently of one another are aliphatic hydrocarbon residues with one to eight carbon atoms, a and b independently of one another are integers from 1 to 4, c is an integer from 0 to 4, d is an integer from 1 to 4, n is 2, 3 or 4, and m is 1, 2, 3 or 4, with the proviso that R1 and R4 may be different within a molecule within the given definitions. These compounds are characterized by a very good complexation power for metal cations and can be used in detergents and cleaning agents, in oil extraction and for water softening.
