Abstract: A composition that includes (i) one or more surfactants derived from a fatty acid and an amino acid and (ii) a solvent, and having a pH of 3.0 to 11.0. In the context of the present invention, the term “surfactant derived from a fatty acid and an amino acid” is understood to denote the molecules of formula (I), where R1 is a C8 to C24 alkyl or alkenyl group; R2 is —H, a C1 to C4 alkyl group, a phenyl group or —CH2COOM; R3 is —C—R42; n is 1 to 4; R4 is H, a C1 to C6 alkyl group or a C1 to C6 alkyl ester; and M is H or a cation, or a mixture thereof.
