Photo Forum / Film Photography / Darkroom / February 2007Stabilizer in Tetinal C-41 1 ltr. Press Kit
I know that this question has been posted previously, however I am not sure that anyone has offered a fix. When I use the Tetinal C-41 press kit I get a nasty white residue on my negatives upon drying after I use the stabilizer. Has anyone out there who has encountered similar problems found a satisfactory way to resolve this? > I know that this question has been posted previously, however I am not > sure that anyone has offered a fix.

Both are used highly dilute. Phoflo won't effect the dyes directly, but it would dilute or wash out the residual stabilizer, which would diminish or remove its effect. So, post-stabilizer rinse, with or w/o photflo, is a bad idea. Most stabilizers, particularly formalin based ones, dry to a white residue when in stock or concentrated form. Just my guess, but could you be using your stabilizer in an excessive concentration by accident? > > In article <1172363962.768535.270...@s48g2000cws.googlegroups.com>, > > "mill...@alaska.net" <mill...@alaska.net> wrote: [quoted text clipped - 18 lines] > when in stock or concentrated form.

The Tetinal C-41 press kit supplys all of its chemistry in solid form. I really have been wondering about the "stabilizer" that they provide, as I have not heard of formaldehyde in a solid form. In reviewing my info sheet from Tetinal, I note that their "stabilizer" contains "aldehyde compound." I am not sure what that is, but I certainly sounds like a compound similar to formaldehyde. All of that said, it is pretty difficult to use at excessive concentration of stabilizer as the powdered chemistry is mixed to the working strength. So far, I think that Gregs suggestion of seeing whether a local photolab can order some stabilizer for me in their next order may be my best option. In the past I have never had this difficulty when I have mixed stabilizer from concentrate liquid chemistry.

Well I am not sure. I am tempted to because I really cant print through the spotting that I get however, I really don't want my negatives to fade. I may do that until I can obtain a different brand of stabilizer which hopefully will not give me the same difficulty. > Well I am not sure.

Actually my question wasn't directed to you, however I'll check with Tetenal from my work tomorrow. I work for the US distributer so perhaps I'll get a more expedient answer. Take care.

Quayle are quite tasty if you roast them correctly (on a mesquite spit)........bacon threaded through them helps.....ah and don't forget some blue cheese peppercorn dressing :) SignatureGeorge W.

I've seen warnings from a retired Kodak scientist to not rinse color film after it's been through the stabilizer (even after it's dried); apparently the stabilizer takes some time to act fully, and rinsing the film will wash away the trace amounts that remain behind after the film dries. I'd imagine that Photo Flo would count as a rinse in this context, so I wouldn't do it. For your main problem, though, I have two comments: 1) Most modern C-41 films don't require the old-style stabilizer; instead, they require a new "final rinse" product. Details of what works with what seem thin on the ground, but as far as I can tell, stabilizer is good to use with old or new films but final rinse should only be used with new films. OTOH, stabilizer contains formaldehyde, so you should exercise more care in its use. 2) Unless you've got a reason to favor the stabilizer provided by Tetenal, you might want to consider picking up some Kodak or Fuji stabilizer (or final rinse if you're using exclusively newer Kodak and Fuji films) to use instead of the Tetenal product. Adorama (http://www.adorama.com) has it and will ship it. (I'm not sure about shipping to Alaska, though; if your e-mail address is any indication that could be an issue.) You could also check with some local 1-hour labs and see if they'll add some stabilizer to their next order of chemicals for you.
