Abstract: The invention relates to a method of reducing the inhalation toxicity of functional fluids by incorporating into a functional fluid an effective amount of a copolymer which is obtainable by copolymerizing ethylene oxide, propylene oxide and/or butylene oxide with an initiator monool or diol, said copolymer having a degree of unsaturation of less than about 0.01 meq/g.

Abstract: The invention relates to the use of fatty acid salts of alkoxylated oligoamines (I), whereby: A represents alkylene groups having 2 to 8 C atoms; R represents C7 to C23 alkyl groups or monounsaturated or polyunsaturated C7 to C23 alkenyl groups; Z represents C1 to C8 alkylene groupings, C3 to C8 cycloalkylene groupings or C6 to C12 arylene or aryl alkylene groupings; m represents 0 or a whole number ranging from 1 to 5, and the sum of all variables x has a value ranging from 50 % to 300 % of (m+3). Said fatty acid salts of alkoxylated oligoamines are used as lubricity improvers for petroleum products, especially for gasolines and middle distillates.
