Still using D-76/ID-11?

[bernard_L]

People regularly slather Hydroquinone on their skin: https://www.webmd.com/drugs/2/drug-1347/hydroquinone-topical/details - usually under a dermatologist's advice and supervision/prescription. Any substance in the universe can be written up as horribly hazardous, Hydrogen Hydroxide HOH (or some other fanciful name for water) is often cited as an example: "Warning - Inhalation Hazard", and it is.

Hydroquinone is used in hair dyes as dying substance. Hundreds of millions of people put it on their heads.......
In modern public waste water systems it is metabolized to not dangerous products by the bacteria used in theses systems for biological cleaning.

Borax, Hydroquinone, ... Yes, at certain doses, some effects have been seen under laboratory conditions;
Borax (or borax-boric acid buffer) was (is?) at hand in chemistry labs, as wall-mounted sprayers, for emergency spraying of eyes affected by projections of nasty (really nasty) chemicals.
Hydroquinone. Excerpt from the document linked to by Philippe-Georges:

The Europea Economic Community (EEC) countries have restricted its use in
cosmetics to 2% or less. In the USA, the Food and Drug Administration
has proposed concentrations between 1.5 and 2% in skin lighteners.
Concentrations up to 4% may be found in prescription drugs.​

Raising alarms out of proportion with the risks is not conducive to informed and responsible behavior. Take mercury. Some people consider CFL's (now quasi obsolete) as evil because of the mercury inside; see what the US EPA has to say: https://www.epa.gov/cfl/what-are-connections-between-mercury-and-cfls. The real nasty stuff is methyl mercury. Brought to you with your daily ration of fish.
Sodium dichromate: I wear gloves, and reduce it to Cr(+3) before disposal. Still chromium (same element), but different chemical species.
etc...

Thank you very much.
Have you found it in the MSDS? I have looked at it and did not found it, but maybe I have overlooked it, or missed it because of a different technical term used for it.......

CAS 140-01-2 is Trilon-C and CAS 164462-16-2 is Trilon-M.

CAS 140-01-2 is Trilon-C and CAS 164462-16-2 is Trilon-M.

Oh, so have indeed overlooked it because of the different technical terms.
Thank you very much!

The environmental impact of ID-11 or D76 is negligible. The powder kits sold by Kodak and Ilford are designed for domestic water waste treatment systems and for ordinary mortals to handle. Honestly unless you start guzzling it you're probably safe. Wear gloves if you think you might have skin allergies. Don't splash it in your eyes. Don't drink it.

Many things are "known to cause cancer in the state of California" which the entire rest of the world view as safe. But even stuff which are worldwide designated as various classes of carcinogen might be safe for consumption. Parsnips, for example. There's a big difference between class 1 carcinogen which effectively means take all precautions to eliminate consumption, inhalation and skin absorption of this stuff cos it's nasty....to class 3 carcinogen which more or less means "we fed mice on concentrated extracts of something in this and bathed their balls in it....and found slight evidence of cancer and genetic mutation".

though I don't specifically recommend this, when I was a child I used to develop positive paper in ID-11 and Bromophen using my mother's roasting trays. They're still in use some 40 years later and nobody seems to have suffered. Though I repeat, I specifically do not recommend using cookware actually used for cooking to mix or use photo chemicals.

I tried this once when I was a teen. Mom caught me red-handed. My allowance paid for new pans.

I started out with a Tri-Chem pack and some bowls taken from the kitchen. See-sawing 127 film through the developer with a couple of clothespins. Had a red Christmas tree light for a safelight - that's when I learned the difference between panchromatic and orthochromatic. After a few months of this my mother took me to the photo store to buy an fr developing tank; it was really expensive, $3.95 or something.
