A product resulting from the reaction of at least:
- a hydroxybenzoic acid, optionally substituted by a hydrocarbyl group,
- a boron compound,
- an amine component selected from a di-fatty-alkyl(ene) polyalkylamine composition comprising one or more polyalkylamines of formulae (I) or (II):
- wherein,
- each R is, independent of the other R, an alkyl moiety or an alkylene moiety with 4 to 30 carbon atoms, which is linear or branched,
- n and z are independent of each other either 0, 1, 2, or 3, and
- when z is greater-than 0 then o and p are independent of each other either 0, 1, 2, or 3,
- or derivatives thereof selected from products wherein one or more of the NH moieties of the dialkyl polyalkylamines are methylated, alkoxylated, or both,
- whereby said polyalkylamine composition comprises at least 3% by weight of branched compounds of formula (I) or (II), with regards to the total weight of polyalkylamine compounds (I) and (II) in the composition, branched compound signifying that:
- in formula (I) at least one of n and z are greater than or equal to 1,
- in formula (II) n is greater than or equal to 1.
