Okay fair enough, my wording was off. But this is what cinestill also say on their website as well:I don't believe that is what Ron Mowrey indicated in that thread.
I believe that what he was saying in that thread is that very old films required formalin in order to react with left over couples and also the gelatin to form substances that resisted both coupler induced degradation and the bug (fungus) attacks.
Modern, post ~2003 C41-films included revised couplers that didn't require formalin in order to resist coupler induced degradation, but were still vulnerable to fungus. The post-2003 final rinse was brought in to provide a photo-flo like surfactant, and the necessary biocide.
Which aligns perfectly with what @MattKing and before him PE said, and is NOT about biocides.But this is what cinestill also say on their website as well:
Stabilizers, no. But the final bath in color processing can serve 3 distinct functions:I have heard from multiple people that stabilizers aren't necessary anymore in c-41 films
Ah right i see, all makes sense now. i should do more research before commenting next timeWhich aligns perfectly with what @MattKing and before him PE said, and is NOT about biocides.
Stabilizers, no. But the final bath in color processing can serve 3 distinct functions:
* Dye stabilization
* Protection against biological agents
* Prevention of drying marks & opt. dust (antistatic action)
The reformulation of films only addressed the first item. The other two remain unchanged since the birth of color film about 100 years ago...
I noticed freestyle is selling a C41 kit minus the stabilizer. They call it a C41s kit and claim in most cases the stabilizer is not needed.
Has anyone tried the kit or know about if this claim is true?
No. Not since ca. 2000 in any case, when C41 dyes were re-engineered to eliminate the necessity for formalin-stabilization. Today there's nothing in 'stabilizer' (more accurately: 'final rinse') that does anything with dye stability.Whatever they add or subtract from the C41 mix the stabilizer also assists to resist the fading of the dyes used to make up the colour element.
C41 final rinse from Kodak and Fuji has a biocide to keep microbes from feasting on the gelatin. I believe that the EU led the adoption of Miconazole, anti-fungal. Color film is silver free after processing needs something.
Miconazole is a trivial name for,I don't know for Fuji but the Kodak Final Rinse bacterial / fungal "antibiotic" agent is a mixture of Chloromethylisothiazolinone and Methylisothiazolinone 0.3%
My dear brother (a perfect man)It is the Cinestill powder chemistry, stabilizer is not included but reccomended in the instructions. Rudeous comment recently that the biocide present in the stabilizer is considered dangerous (by inhalation) in powder form and the reason why it is not included in the kit.
Is there a formula for a powder that can be dissolved in water to become a staplizer? The answer, I think, is that there is no such formula as far as I know.
If there is such a formula, I hope colleagues will tell me about it.
Thank you very much for the response.Hexamine powder, as found in Unicolor C-41 kits & others, when it decomposes in water forms Formaldehyde which has the dual function of dye stabilizer (on pre-2003 emulsions) and anti-fungal agent. However, this solid form of CH₂O can leave dry marks on negatives which is the reason why prefer Kodak Final Rinse.
Note: I’d use Hexamine powder for pre-2003 films as it’s easier to get than Formalin.
What is the possible formula for preparing this bag, which will then be dissolved in water to become a solution (stablizer). ?
I will be very grateful to any colleague who can help me in this matter.
God bless you.
