Closest film dev. to hc-110

[kmphoto]

I haven't found a replacement dev. for Kodak hc-110.
(To many dev. names to sort through when I could be shooting).
I Know we can still get hc-110.
I'm wondering if I can "home brew 110 myself"??
Or what is close???

I heard and read a few times D-76 is what Hc 110 was developed to give results like....

Can't see why you want to brew HC 110 yourself I think it is a mystery mix (I think Kodak developed some of the chemicals themselves) a excellent developer and fairly priced considering it's keeping properties......Rodinal now that's a different story for D.I.Y

Freestyle sells a hc110 clone

I have used Legacy L110 available from Freestyle. Supposedly it's similar to HC110 but it doesn't last as long as HC110. It's best to put it in smaller bottles to keep the air out. It's good, but I've never used HC110 that much to give it a fair comparison.

Ilfotec HC is Ilford's version of HC-110. Why are you looking to substitute HC-110 with a duplicate? What is it about HC-110 you want to keep vs. what is it about HC-110 that makes you not want HC-110? This info would be helpful to recommending something else.

The problem with any of the clones is that they contain water in the concentrate. HC-110 contains no water the solvents are glycols. It is water that permits things to oxidize. Put a piece of bright polished iron in an pure oxygen environment from which all water has been removed and it will not rust.

AFAIK, HC-110 uses adducts of Triethanolamine with Sulfite and Bromide to provide these ions to the developer working solution. These adducts are made by streaming SO2 and HBr gas into Triethanolamine. Both gases are not suited for handling at home (or anywhere outside special facilities), so home brewing of HC-110 is pretty much out of the question, even if the complete formula became public.

 

[Gerald C Koch]

The formula given in the patent is probably very close to what is sold. The patent number is U. S. Patent 3,552,969 (1971), It is also given in The Film Developing Cookbook, by Stephen G. Anchell and Bill Troop, p. 58 although it incorrectly lists water as a constituent!

The formula calls for the adduct of HBr with DEA. Need space for the hydrogen ion on the HBr. TEA is fine for the sulfur dioxide adduct though. The patent also uses the correct chemical names for DEA and TEA.

I am confused as to why you can't just use Hc110. The way the original post is written made me look to see if it had been discontinued. 1 liter can make an enormous amount of diluted developer. All the work and time it would take trying to make it at home when you are concerned about time lost researching different developer names has me confused. Did you not know that you could just buy HC110? http://www.freestylephoto.biz/5010541-Kodak-HC-110-Film-Developer-1-Liter-(Makes-32-Liters)

Did it use to be cheaper, or am I thinking of the old half size bottles that seem to implode and sometimes crack open after a few years? (though the stuff [as a concentrate if you do one shot development like I tend to] seems to last forever if you can seal it securely, and if it's crystalizing you just heat it back up to dissolve)

Now that's why I buy a yellow filled bottle with Kodak on the label.

 

[Nodda Duma]

HC-110 is still readily available. So a good substitute would be a new bottle of Kodak HC-110

 

[Gerald C Koch]

Interestingly based on the msds HC110 contains a small amount of catechol.

Yes, <1%. Since it also contains hydroquinone and Dimezone I wonder just what purpose the catechol serves.

I was just wondering if hc110 can be mixed as a home brew...
Or if there is something very much like it.
I used 110 for many years professionally.
Now semi-retired I thought I might tinker with it if possible to make...

Thanks for your thoughts!

I just get 4oz bottles from the drugstore and break down the bottle into them. That way if some goes bad you only lose 4oz.

I started off using D76 mostly using it 1:1, I have now switched to HC110 mainly at 1:100.

The HC110 builds highlight contrast faster than D76 with similar agitation, so I have gone to a reduced agitation, extended dev time protocol.

 

[M Carter]

Just one opinion, but after lots of testing - any film I'd think of using HC-110 for, I just like Rodinal better. It's subtle, but there's some kinda mojo with the Rodinal. And I like how dilution strengths adds some contrast variations.

Of course this all varies with individual process and tastes, and I'm much more into sort of "transformative" looks in the final print vs. straight-up documentary work, but I keep coming back to the stuff for slower films. (HC-110 is very handy for ortho-litho film though).

...."I buy 4oz. bottles at the drug store"...
It's kind of funny.. I used to ride my bike to the drug store & buy my Kodak B&W film, paper & chemicals there.

Dektol,D76, DK50 & fixer were sold in metal cans you opened with a can opener..

Back in the 80s, the color of HC-110 changed dramatically from a yellowish brown to the current yellow. The change was obvious as it then came in clear plastic bottles. Development times changed a bit, too, at least for Tri-X. Does anyone have any idea what changed and why?

 

[Gerald C Koch]

It appears to use Phenidone B as opposed to Dimezone.

It took me three attempts to find an MSDS that mentions any of the pyrazolidone developing agents. The one I did find for 2/5/2014 does contain Phedidone B. Of course companies like Kodak do make unannounced changes to their product usually to benefit the bottom line.
