"Although Kodak D-76 and Ilford ID-11 are ostensibly the same formula there are a few differences. Ilford sells ID-11 in two separate packages. Teh first contains metol, the second sulfite. This eliminates the need for some of the additives which Kodak includes in their single package & may allow the Ilford formula to perform closer to the original." (Film Developing Cookbook.
