Abstract: The invention relates to the use of a specific type of calcium catalyst (C) for the preparation of alkoxylated glycerol esters, alkoxylated glycerol esters prepared in the presence of the catalyst and a process for the preparation of the alkoxylated glycerol esters. It was found that in the presence of the above-mentioned calcium catalyst (C) the alkoxylation reaction requires a significantly smaller amount of time. Furthermore, it has been found that the ethoxylated glycerol esters prepared in the presence of calcium catalyst (C) lead to more homogeneous products with significantly lower hydroxyl values, less decomposition and improved processability.

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.

Abstract: The present invention contains methods, of making a cashew nutshell liquid alkoxylate sulfate surfactant by alkoxylation of a natural alkylphenol using propylene oxide (PO) and/or ethylene oxide (EO) followed by a sulfation reaction. The cashew nutshell liquid alkoxylate sulfate surfactant of the present invention is made by a facile and cost effective method. The natural hydrophobe surfactant of the present invention find uses in EOR applications where it is used for solubilization and mobilization of oil optionally containing asphaltene, wax, naphtenate, and for environmental cleanup. Further, the unsulfated version of the natural hydrophobe cardanol alkoxylate surfactant of the present invention can be used as ultra-high molecular weight non-ionic surfactant. Another advantage is that the composition is a renewable based surfactant that is non-toxic and biodegradable.
