Abstract: The present invention relates to dispersants comprising a polyester derived from a plurality of poly(carbonylalkyleneoxy) chains (and optionally a fatty acid) and an amine, wherein said dispersants have an acid value of less than 15 mgKOH/g. The dispersants as described herein provide desirable viscosity profiles when in use. More especially some embodiments provide improved compatibility with certain solvents in dispersions, and/or are particularly suitable for use in battery systems.

Abstract: A composition which is the reaction product of reactants comprising dimer fatty acid and/or trimer fatty acid, a mono-alcohol comprising at least 3 carbon atoms and a polyol comprising at least 2 hydroxyl groups. The composition comprises dimer fatty diester and/or trimer fatty trimester, and oligoester comprising more than one dimer fatty acid and/or trimer fatty acid residue. The invention also provides an emulsion comprising the composition, particularly in the form of a personal care product, a method of emulsifying using the composition and use of the composition as an emulsifier.
