What does one do with photoflo after rinsing their negatives?

Down the drain? Back in he bottle for more use? Some sort of special disposal?

Thanks!

It's not soap it's ethylene glycol which is chemically the same as antifreeze. It's toxic to pets and dogs have a thirst for it but it is deadly to them.

My kitty cats dive for the sink after I discard HC-110 and PhotoFlo however they’re still alive so I think you’re full of BS.

No thanks to you for the misinformation and paranoia.

Actually, Photo Flo contains propylene glycol, NOT the ethylene glycol found in antifreeze.


According to DOW chemicals:

"Propylene glycols are most commonly used in applications in which low acute oral toxicity is required, or for freeze protection where incidental contact with drinking water is possible."
 
... I always thought it was the same as Fairy Liquid (the detergent for the dishes) ... I'd been using that since I finished a bottle of that Ilford wetting agent some time in the nineteen-eighties
 
I always use it as a mixer for my mother-in-laws whiskey sours. Old gal can't get enough. She's always snooping around my darkroom and commenting, "Hey there Sonny, isn't it about time you brewed a new batch of Photo-Flo -- it's looking rather ripe!" And I reply so are you mother, so are you. She's not so fond of the hypo, tho lord knows I've tried. And to all you worrisome fruitcakes, this is a joke :)
 
... no good telling to us ... its GCHQ that need to see the funny side of it


(this is also a joke for no good reason)

Presumably your negatives are now as soft as your face?

Photo flo 600 which I use is ethylene glycol. Look it up.

The Photoflo 600 that Kodak makes and I use is ethylene glycol. Read this and be a little more polite next time.

Read this on propylene glycol

Is not 600 vs 200 just the concentration of the product as distributed and the amount of dilution required? Kodak's Material Safety Data Sheet for Photoflo 200 says:
"2. COMPOSITION/INFORMATION ON INGREDIENTS
Weight % - Component - (CAS Registry No.)
60-70 Water (007732-18-5)
25-30 Propylene glycol (000057-55-6)
5-10 p-tert-octylphenoxy polyethoxyethyl alcohol (009002-93-1)"
Does the label on the 600 bottle say "ethylene glycol"? I can't find Photoflo 600 on Kodak's web site. Maybe 200 and 600 are different.
 
Quoted from Kodak's MSDS sheet for Photo-Flo 600:

3. Composition/information on ingredients
Weight ---------- Components (CAS-No.)
percent
35-40 ------------ Ethylene glycol (107-21-1)
25-30 ------------ p-tert-octylphenoxy polyethoxyethyl alcohol (9002-93-1)​
 
fwiw, Photo Flo 600 is 'unofficially' discontinued or at the very least no longer sold to consumers via the usual vendors (B+H, Freestyle, Adorama, etc..) It was delisted by Kodak in 2009 but then reinstated later as a catalog number in their Motion Picture products catalog.

Photo Flo 200 MSDS sheet: http://www.freestylephoto.biz/pdf/msds/kodak/Kodak_PhotoFlo_1464254.pdf

Legacy Pro 600 wetting agent MSDS sheet (which is the same product as the old Kodak 600): http://www.freestylephoto.biz/pdf/msds/legacypro/LegacyPro_600_Wetting_Agent.pdf

Edwal LFN Wetting Agent MSDS sheet (which is supposedly more user friendly; I use it): http://www.freestylephoto.biz/pdf/msds/edwal/Edwal_LFN_Wetting_Agent.pdf

The Legacy Pro 600 is the same formula as the Kodak 600 and contains ethylene glycol....
 
I have a quantity of 600 that I've had for 30 years. It only takes a few of drops in 32 ounces so a gallon lasts for decades. Where I used to work in the early 70's we used the 1200 concentration.

From what I read the older 200 was ethylene glycol and contained formaldehyde also. I need to go to my photo lab index and check. It's my understanding 200 was re formulated a few years ago but not the 600. Depending on the age of what you have it could be ethylene glycol.

If you read the attached articles above you'll find propylene glycol is quite toxic to cats and was banned from use in cat food by the FDA.
 
From Wikipedia:
Animals[edit]
Propylene glycol is an approved food additive for dog food under the category of animal feed and is generally recognized as safe for dogs,[42] with an LD50 of 9 mL/kg. The LD50 is higher for most laboratory animals (20 mL/kg).[43] However, it is prohibited for use in food for cats due to links to Heinz body anemia.[44]
