    Abstract: Alkoxylated polycarboxylic acid esters are provided obtainable by first reacting an aromatic polycarboxylic acid containing at least three carboxylic acid units or anhydrides derived therefrom, preferably an aromatic polycarboxylic acid containing three or four carboxylic acid units or anhydrides derived therefrom, more preferably an aromatic polycarboxylic acid containing three carboxylic acid units or anhydrides derived therefrom, even more preferably trimellitic acid or trimellitic acid anhydride, most preferably trimellitic acid anhydride, with an alcohol alkoxylate and in a second step reacting the resulting product with an alcohol or a mixture of alcohols, preferably with an alcohol.

    Abstract: Alkoxylates are described that are obtainable by (i) in a first step reacting a) one or more compounds selected from the group consisting of phenols that are substituted with one substituent, wherein the one substituent is in the ortho-, meta- or para-position to the OH group of the phenol and is selected from the group consisting of OH, R8, OR8, F, Cl, Br, I, CN, NO2 or COOR9, wherein R8 is a linear or branched alkyl group with 1 to 4 C-atoms and R9 is a linear or branched alkyl group comprising 1 to 22 C-atoms or a linear or branched mono- or polyunsaturated alkenyl group comprising 2 to 22 C-atoms with b) an aryl-substituted linear or branched C1-C3 alkyl alcohol or an aryl-substituted linear or branched C2- or C3-alkene, and (ii) in a second step alkoxylating the reaction product of the first step and (iii) in an optional third step reacting the reaction product of step (ii) with an alkylating agent providing a C1-C4 alkyl group, with a carboxymethylating agent, with a sulfating agent, with a phosphating agent or with a sulfosuccinating agent. These alkoxylates may advantageously be used as anti-redeposition agents in laundry applications.

    Abstract: Alkoxylates according to the following formula (I) are described, wherein X is selected from ethoxy and mixtures of ethoxy and propoxy groups, T is selected from the group consisting of H, C1-C4 alkyl, SO3−, CH2—COO−, sulfosuccinate and PO32−, R1, R2 and R4 are H, CO—NR8R3 or COO—[X1]v—R3, whereby two of the substituents R1, R2 and R4 are H and the third of these substituents is CO—NR8R3 or COO—[X1]v—R3, R8 is H or a linear or branched alkyl group with 1 to 4 C-atoms, R3 is a linear or branched saturated alkyl group with 6 to 30 carbon atoms, a linear or branched mono- or polyunsaturated alkenyl group with 6 to 30 carbon atoms, an aryl group with 6 to 10 carbon atoms, a group (CH2CH2O)maryl, wherein the aryl group comprises 6 to 10 carbon atoms and m, on a molar average, is a number from 1 to 100, or an aryl-substituted linear or branched C1-C3 alkyl group wherein the aryl group comprises 6 to 10 carbon atoms, but in the case, that R1 and R4 are H and R2 is COOR3, R3 can only be an alkyl group, an alkenyl group or a group (CH2CH2O)maryl as defined above, X1 is selected from ethoxy and mixtures of ethoxy and propoxy groups, u on a molar average, is a number of from 3 to 100, and v on a molar average, is a number of from 0 to 20. The compounds of formula (I) may advantageously be used as anti-redeposition agents in laundry applications.
