Just a minor update, I recently ordered some chemistry from Unique Photo. To my surprise, they were competitive on price, having a fantastic deal on bleach III (free shipping! for the 50L sizes), making that worth stocking up on. 50L of bleach with regeneration will do at least 2200-2500 rolls of film (120 or 35mm). They had good prices and non-hazmat shipping on many of the other C-41 chemicals too. I think the only thing that shipped hazmat was developer replenisher. Great customer service from them too. I ordered something twice by mistake and they were super helpful in getting that sorted out quick and easily.
I'm running low on C-41 bleach. Can someone comment on this bleach for manual development in a small tank?
It's Kodak Flexicolor RA (C-41RA) Bleach Replenisher NR for Color Negative Film. According to the product description, it "requires no mixing; it is packaged ready to use." I realize this is packaged and marketed for labs, so I'm wondering if it works out of the box. It's not a Part A. Thanks.
It should work, but I'd look (maybe elsewhere?) for bleach III. It will be more economical and better suited to your use, I'd think. Unique has bleach III in the 50L size, but it is also available in smaller sizes I think. Check for the fuji and champion equivalents too. (Unique carries those brands).
Thanks. So the jury is out on the C-41RA bleach from Kodak...
Meantime, I found this C-41 bleach product from Fuji:
There's no useful product description, but I found this tech sheet from Fuji:
Sounds promising if it will work. And $40 for 2.7 liters is about the best price I've found for a small quantity.
Try it and let us know how it works out. Bleach is pricey but almost infinitely recyclable (with regeneration).
I've used it, it will work. The RA process has shorter bleach and fix times due to a higher concentration for these steps. It's designed for minilabs that need a fast access time and it's also designed for use in washless systems. The developer is the same as regular C-41. This bleach is ready to use out of the bottle but it's kinda expensive. The bleach III is a better fit for home darkroom use.

If the RA process bleach works just the same and is no less archival, then it might be a better fit for me. It still makes five liters, which isn't exactly scant.
It's the cheapest way I'm aware of to get SOME bleach. Just be sure to use the processing times for the RA process from Kodak. One minute at 38 degrees C for the bleach and 1.5-2 minutes at 38 degrees C for the RA fixer. I didn't experiment much with it to see what it does at lower temps. I don't know if there's any difference in archival properties or other quality metrics. I do know it's designed to be the fastest C-41 process for minilabs.
The SM tank solution is also an alternative but it comes in a 10L size for around $90. I do a fair amount of C-41 so I just recently bought the 50L bleach III. This combined with what I have on hand should last me some time. Bleach has a very long shelf life.
Agreed re: Bleach III. I bought the 50L size recently and it will last me a LONG time. $165 sounds like a lot but consider that will do at least 2000+ rolls of film, and probably more. and will keep nearly forever, mixed or not. Maybe find another local C41 user and split it with them? Or a local minilab that will sell you some bleach ala carte?
