Hey guys

Does this look familiar to anyone ? what is this anyway ? It's the second time I see it. For reference it's a bottle of undiluted Xtol, stoppered, 1 month old and was stored inside a black bag in a closet.
There's some dried solution you can see on the outside of the bottle, I'm talking about the stuff inside

I don't know what it is but I get the same wisps in near full stoppered plastic bottles of stock XTOL (that I mix using distilled water). I use the solution anyway after giving it a good stir and it seems to work fine.
 
Looks like some kind of soft precipitate as opposed to undissolved powder. Are you making up the XTOL as directed, i.e., completely dissolving Part A before adding Part B? And within the temperature range in the instructions?

I have never had this problem and I have stored individual liters of stock in PET plastic bottles squeezed to eliminate air and stored in the dark for up to 6 months.
 
I would call Kodak, 800 247 2424 I think. Ask for Profesional Help

The container may have been contaminated

I would not risk film in this after all the work making the images.

Always use the same container for each chemical. Glass is better to clean than plastic. I got rid of all plastic in my darkroom decades ago Worth every penny
Specialty Bottle Company

I also use D76 which is very easy to mix so you know how fresh it is.

Since multiple people are having problems, it is likely a Kodak Problem that they already know about. They replaced all kinds of bad Xtol for me. I finally got tired of it, and went back to home made D76.
 
Thanks, I only use stoppered glass bottles and I don't mix the bottles between chemicals (that is, xtol bottles are marked as such and always contain only xtol)
Since it's the second time I see it, I was a little more careful this time while mixing but there was no change

And yes it seems to be a precipitate of some sort, given that the active agents in Xtol are ascorbic acid and phenidone, what would precipitate Xtol ? maybe fixer contamination ?
 
My guess would be some impurities in the water or in the packaged chemical.

I mix Xtol in our local fairly good tap water and I get a small amount of wispy cloudy stuff that settles. It doesn't want to redissolve, but I suspect that it never really was dissolved but rather it would have been finely dispersed (insoluble) in the developer when first mixed and then it aggregated together. However yours looks a lot more than mine have ever looked.

Depending on bottle size and usage, I try to decant it off, so I waste some developer. It's not expensive compared to other costs of our photographic activities.
