Indeed, and these posts from 3+ years agoThere are many versions of D76, the Kodak version has changed over the past 100 or so years
The published formulas for D-76 and ID-11 ARE identical but both have "secret sauce" ingredients that are proprietary trade secrets to make them less likely to increase in pH as they are stored and also make them simpler to mix.D76 is the same developer I think.

The only sauces are the sequestering compounds in D-76 to allow for single packages/mixing.
I just checked the 4 or 5 usual stores where I buy supplies and ID-11 is out of stock everywhere. Finally found a shop in Lille, put in an order only to get a phone call later telling me that it's out of stock and they don't expect new supplies for another month. No clue as to why this is happening...So, what other developers compare? I really like the fine grain and contrast I get with it.
Thanks!
Mixing D76 is a bit like pouring draught Guinness. You have to wait for it. Never use on the same day you mix.
I have like you read this time and again. But never in the Eastman Kodak printed literature.You have to wait for it. Never use on the same day you mix.

Is that your personal experience? Like, e.g., identical exposed frames, develop one as soon as mixed dev has cooled down to 20°C, second one 24hrs later?

if it's lacking Hydroquinone and Metol, then it isn't D-76 ; )There is a "human friendly" version of D-76 (and Dektol), by Chris Patton (Stanford.edu) lacking Hydroquinone and Metol.
BTW: I always wondered if (standard-) Dektol could be 'altered' so it could be used as a decent film developer, just in case when D-76 wasn't available.
Dektol's (= D-72) formula looks so similar as D-76...
A patent I read years ago about single powder developers mentioned Lithium hydrochloride being used in the packaging. I wonder if that helps it to dissolve more easily. It's probably present in a very small quantity.

Yes, boric anhydride was mentioned in the patent too along with lithium hydroxide. It was a developer of the D76 type.Kodak had several patents in the 1950s related to packaging powder developers in single packets. In that context I recall lithium hydroxide being used mostly in highly alkaline developer formulas in place of sodium hydroxide but you might be right. An example of a stabilizing compound for single packaging is boric anhydride (still used in D-76…).

I have often switched between D-76/ID-11 and XTOL. They both are general purpose developers. You can make the case XTOL has the advantage on ID-11 but at my size prints I don’t see a meaningful difference. Advantage XTOL is its fully researched with developing times applied to films.
