An amido peroxyacid having formula (I) wherein R is selected from the group consisting of C1-C16 alkylene, C5-C12 cycloalkylene, C6-C12 arylene radicals; R1 and R2 are selected from the group consisting of hydrogen, C1-C16 alkyl, C5- C12 cycloalkyl and C6-C12 aryl radicals; R3 is selected from the group consisting of C1-C16 alkylene, C5-C12 cycloalkylene and C6-C12 arylene radicals; n and m are integers whose sum is 1; and M is selected from the group consisting of hydrogen, alkali metal, alkaline earth metal, ammonium and C1-C10 alkanolammonium cations and radicals. The amido peroxyacid is useful for bleaching substrates such as stained laundry, dishware and household hard surfaces. A method and bleaching composition that includes a surfactant is also described.

Amidoperoxyacide de formule (I) dans laquelle R est choisi dans le groupe constitué de radicaux alkylène C1-C16, cycloalkylène C5-C12 et arylène C1-C12; R<1> et R<2> sont choisis dans le groupe constitué d'hydrogène et de radicaux alkyle C1-C16, cycloalkyle C5-C12 et aryle C6-C12; R<3> est choisi dans le groupe constitué de radicaux alkylène C1-C16, cycloalkylène C5-C12 et arylène C6-C12; n et m sont des nombres entiers dont la somme est 1; et M est choisi dans le groupe constitué de cations et radicaux d'hydrogène, de métaux alcalins, de métaux alcalino-terreux, d'ammonium et d'alcanolammonium C1-C10. Ledit amidoperoxyacide est utile pour blanchir des substrats tels que des vêtements, de la vaisselle et des surfaces ménagères dures tachés. Un procédé et une composition de blanchiment contenant un tensioactif sont également décrits.
