DEFINITION

Classification: 510/312

With nitrogen or oxygen containing bleach precursor or activator (e.g., ester, acid anhydride, etc.):

(under subclass 309) Compositions which additionally include a nitrogen or oxygen containing component which acts as a precursor or activator for the peroxy bleach component by increasing its bleaching capacity, especially at lower washing temperatures.

(1) Note. The activator component may act as a percarboxylic acid or salt bleach precursor, such acid or salt being formed in the presence of an inorganic peroxide.
