In my opinion - which is based on nothing more than not remembering
seeing anything on the labeling - nope, not unless you're planning on drinking them. |

Prolonged exposure in the place that makes the raw components? probably.
Exposure in a Kodak factory compounding the formulas? less likely. Exposure in a commercial lab processing paper or film everyday, hardly possible. Home darkroom, not very likely at all! Fed to lab rats at prodigious rates to get a reaction? Absolutely. My wife once worked for a microbiologist that was phobic about germs--not a very happy man! If you are that concerned about cancer you should probably take up a different hobby, but note that carcinogens exist in every place that we live, work, and play. Processed foods, cigarette smoke, second-hand cigarette smoke, red wine, processed meats, building products, paints, varnishes, adhesives, insulation, automobile exhaust (especially diesel), power plant emissions, and a lot of so-called natural products. It's all about limiting you cumulative exposure. For me the benefits outweigh the risks, the rewards are worth the exposure. I am always careful working around chemicals, power tools, electricity, firearms, etc. All hobbies have risks and precautions associated with the safe practice of the skills involved. -- darkroommike ---------- "Beppe Alborč" wrote in message ... i've just a little question for you: in your opinion, are the following products carcinogenic, or carcinogenic suspected ? negative film developer: kodak xtol paper developers: kodak ektaflo, kodak selectol thanks! |

Processed foods, cigarette smoke, second-hand cigarette smoke, red wine, processed meats, building products, paints, varnishes, adhesives, insulation, automobile exhaust (especially diesel), power plant emissions, yes, i know that dangers of carcinogens exist everywhere, but i prefer to be as far as i can from all of these substances. here's why i was searching the internet for development products that can't expose me to this risk, because i like darkroom hobby very much! I've discovered that these 2 products : kodak xtol (film developer) kodak selectol soft (paper developer) don't have the hydroquinone in their formulas (i've read them on their data sheets...). so, i was asking myself if these products can't expose people to cancer risk... but i'm not an expert... .... if someone of you can download the data sheets of these 2 products, at the site http://msds.kodak.com/ehswww/external/index.jsp can give me a confimation ? thanks very much, and happy holidays !!!! |

Hydroquinone is probably used for more than a century, it's carcinogen properties have been indicated only recently. As an example, France obliged shops to keep products containing hydroquinone in closed cupboards a couple of years ago, before that it was publicly available on the shelves. And the reason was because some black people used it to whiten their skin (!) ... Who can assure you that in your hydroquinone-free developer there isn't a chemical that will be considered as a potential carcinogen (or harmful in another way) in ten years ? I can't ... Treat the chemicals with respect as others already mentioned it. I don't think any of us, including the radioactive ones :-)), are prone to that any risk with their life. As you still seem to have an hydroquinone phobia, you mentioned Xtol which is a very good choice: I use it because it is an excellent developer not because it is hydroquinone-free. You mentioned Selectol soft. As its name implies, it is a developer giving a softer contrast than classic developers. Not what I call a "standard" paper developer. Useful with graded papers but not that much with VC papers. You may also encounter difficulties to find it, it is not more very common. I already indicated you in another post that Agfa Neutol Plus is a paper developer using Vitamin C instead of hydroquinone. It is much more available in Europe than Selectol Soft. Don't confuse the _Plus_ version with the _NE_ (Neutral tone) or _WA_ (Warm tone) versions of Neutol (available in liquid and powder forms), these are classic metol/hydroquinone paper developers (and good/cheap ones).

If you want to avoid dangerous chemicals, then be sure to stay away from
pyro developers (pyrogallol/catechin/catechol/pyrocatechin), as they are deadly when absorbed through the skin (liquids) or inhaled (powders). They give beautiful results, but should only be used with great precaution. "Beppe Alborč" wrote in message ...
