Tartaric acid diesters as biogradable surfactants

摘要

This invention provides water-based compositions which are essentially free of hydrocarbon solvents, particularly coating, ink, fountain solution, adhesive and agricultural compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of certain tartrate diester compounds of the structure where R1 and R2 are C4 to C6 alkyl groups.n
