Abstract: The present invention relates to a composition comprising at least an ether carboxylic acid. The present invention also relates to the method for obtaining of the composition and to the use of the composition in industrial applications such as engine oil compositions, metal working compositions, lubricant compositions and oil fuel compositions.

Abstract: The present invention relates to novel ionic liquids comprising polyethercarboxylate groups as anions, alkyl ammonium groups as cations, a process of preparation of said ionic liquids and its use in high duty lubricant.

Abstract: The invention refers to lubricant compositions, said lubricant compositions being particularly preferred for conveyor systems, especially in the foodstuff industry, which are suitable for lubricating, cleaning and disinfecting of the transport chains. More specifically, the invention refers to lubricant compositions for conveyor systems comprising: a) one or more phosphoric acid esters; and b) one or more ether carboxylates; and e) water; and c) one or more C6-C22 fatty acids, optionally ethoxylated with to 20 moles of ethylene oxide; and/or d) one or more C6-C22 fatty alcohols, optionally ethoxylated with 1 to 20 moles of ethylene oxide wherein the weight ratio of component (a) to component (b) is in the range of 9:1 to 1:3. Said lubricant compositions can be used in conveyor systems for glass and/or plastic bottles, such as polyethylen terepthalate (PET) or polycarbonate (PC); cans, glass containers, drums, cardboard containers and similar items.
