Bleach compositions

A sanitizing or disinfecting composition comprising:

• (a) about 0.05% to 0.5% by weight of a hypochlorite or free available halide as provided by an oxidant;
• and
• (b) at least one nonionic or zwitterionic surfactant;
• (c) at least 90% water;
• (d) wherein the composition has an R value of about 1, where R is defined as the sum of the concentration of any nonionic or zwitterionic surfactants, divided by total surfactant concentration;
• (e) wherein the composition has a pH from 8 to 12.5;
• (f) wherein the sanitizing or disinfecting composition exhibits at least a 3-log reduction in at least one of an M. bovis or C. diff population within 10 minutes
• (g) wherein the composition comprises a cationic surfactant.

A ready-to-use sanitizing or disinfecting composition comprising:

• (a) about 0.05% to less than 0.5% weight percent of a hypochlorite;
• (b) at least one nonionic or zwitterionic surfactant;
• (c) a cationic surfactant;
• and
• (d) at least 90% water;
• (e) wherein the composition has an R value of about 1, where R is defined as the sum of the concentration of any nonionic or zwitterionic surfactants, divided by total surfactant concentration;
• (f) wherein the composition has a pH from 9 to 11.5;
• (g) wherein the sanitizing or disinfecting composition exhibits at least a 3-log reduction in at least one of an M. bovis or C. diff population within 4 to 6 minutes.
