| There are only certain types of B+W films that are designed to be processed through the C41 color chemicals. Don't put normal B+W films through a C41 process, the C41 runs at a higher temperature, and will soften and possibly remove the gelatin emulsion from the film base. It will also bleach out all the silver, so if the emulsion does hang on, you won't get any image.
If you can find chromogenic B+W film, which will be marked on the cannister as specifically for C41 processsing, then go for it. It's a completely different type of film, the image in this type of film are formed by dyes, not silver.
