  • 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.

  • Publication number: 20230365899
    Abstract: The present invention concerns a composition comprising manganese containing catalyst salts, a water-soluble polymer and a polysaccharide absorbent. The invention also concerns a method of making such compositions, preferably in the form of a granule, and bleaching formulations comprising the salt and a peroxy compound or precursor thereof. The catalyst salt containing composition and formulations comprising it, are suitable for use in catalysing oxidation, for example as a component of a laundry or dishwasher bleaching composition. The invention further relates to cleaning agents comprising the compositions described herein.

  • Patent number: 9777249
    Abstract: Liquid compositions include: a) one or more anionic surfactants and b) one or more nonionic surfactants, wherein they comprise the surfactants of components a) and b) in a total concentration of >25% by weight, based on the total weight of the liquid composition, and are free from alkanolamines and salts thereof. Upon combination with bleaches, the liquid compositions exhibit a significantly higher bleaching efficacy than comparable alkanolamine-containing compositions.

  • Publication number: 20160168514
    Abstract: A method is described for washing and cleaning textiles, wherein A) a liquid composition comprising one or more surfactants and one or more enzymes but no bleaching agents is added to the washing liquor comprising water and the textiles to be washed and cleaned and B) 15 to 30 minutes after adding the liquid composition to the washing liquor, one or more bleaching agents are metered into the washing liquor. The method is characterized in particular by an advantageous washing and cleaning power.

  • Publication number: 20140189960
    Abstract: An improvement for boosting the cleaning capacity of liquid washing compositions provides for the use of a combination of one or more secondary paraffinsulfonates having 8 to 22 carbon atoms and amylase for increasing the cleaning capacity of the liquid washing compositions with respect to starch-containing stains on textiles. In accordance with the invention, it is possible to lower the amount of liquid washing composition with comparable cleaning performance, which brings environmental advantages. Moreover, it is possible to clean at low temperatures, which can reduce energy consumption.
