1. A composition having a pH in a range of 1 to 6, comprising:
hydrogen peroxide; and
one or more compounds selected from
orthodiphenols
imidazolidin-2,4-diones, and salts thereof,
wherein the orthodiphenols have the following general structure:

OG Complex Work Unit Chemistry
wherein R1, R2, and R3 are independently selected from H, OH, halogen, C1-C12 linear or branched alkyl or alkenyl, O—X, NO2, COOH, SO3H, aryl, and heteroaryl, and X is a C1-C12 linear or branched alkyl, and
wherein the imidazolidin-2,4-diones have the following general structure:

OG Complex Work Unit Chemistry
wherein R4, R5, and R6 are independently selected from H, OH, halogen, C1-C12 linear or branched alkyl or alkenyl, O—X, COOH, phenyl, diphenyl, ureyl, and X is a C1-C12 linear or branched alkyl,
wherein the composition is a non-dyeing composition.
