DEGREASING COMPOSITIONS DERIVED FROM LEVULINIC ACID (A COMPOUND OBTAINABLE FROM BIOMASS) AND PROCESS FOR DEGREASING METAL SURFACES

摘要

The present invention relates to a new degreasing composition comprising at least one levulinic acid ester according to general formula (I)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ CH 3 CO(CH 2 ) 2 COOR 1 €ƒ€ƒ€ƒ€ƒ€ƒ (I)
in which R 1 is a linear or branched, saturated or unsaturated, aliphatic or aromatic, hydrocarbon radical having 2 to 56 carbon atoms, wherein said hydrocarbon radical is optionally hydroxysubstituted. The present invention also relates to a process for degreasing a metal surface comprising the step of contacting said metal surface with the composition of the present invention.
