    Abstract: A detergent composition for machine dishwashing comprising Z1) one or more ethoxylated glycerol esters of formula (I), prepared from ethylene oxide and one or more triglycerides of formula (II) in the presence of a calcium catalyst (C), characterized in that R1, R2 and R3 in formulae (I) and (II) are equal or different and are independently selected from saturated or unsaturated, linear or branched C7-C24 alkyl chains, m, n and o in formula (I) are equal or different and are each independently an integer number from 1 to 200 with the proviso that the number-average of the sum of m+n+o is greater than 5; and the calcium catalyst (C) is a catalyst obtainable by a reaction involving (A) calcium hydroxide and (B) a carboxylic acid comprising 3 to 40 carbon atoms, wherein the molar ratio of calcium hydroxide (A) to carboxylic acid (B) in the preparation of the catalyst (C) is from 1:1 to 1:5.

    IPC: C09K8/52

    Abstract: The present disclosure relates to a gas hydrate inhibitor composition comprising an amphiphile having a hydrophobic tail linked to a hydrophilic head group by a linking moiety, the amphiphile having the general formula (1) [R5-L-N(R1)(R2)(R3)]+X−  (1) wherein each of R1 and R2 is independently an alkyl group having from 1 to 5 carbon atoms; or wherein the nitrogen atom and the R1 and R2 groups together form a substituted or unsubstituted heterocyclic group; R3 is present or not as hydrogen or an alkyl group having from 1 to 8 carbon atoms which optionally bears a hydroxy group or a carboxy group in the 2-position; L is a linking moiety comprising an optionally substituted hydrocarbyl group having at least 2 adjacent carbon atoms, at least one heteroatom selected from nitrogen and oxygen, and optionally one or more further heteroatoms; R5 is a hydrocarbyl group having from 6 to 22 carbon atoms; and X− is present as an anion when R3 is present; and a nonionic surfactant which is selected from N-acylated polyhydroxyalkylamines and a method of using the gas hydrate inhibitor composition.
