Hello David.

We do have Hydroquinone in stock, but we need to know what you intend to use it for before we can sell it. Due to misuse by people outside of the photographic industry, we normally only sell small sizes. If you want a larger size, we need to know how much you need and what formula you’re using it for, along with a list of all the chemicals and sizes you wants to order.


Best,

Digitaltruth Photo

People probably use it to silkscreen posters to protest our lazy-*ssed Congress, on both sides of the political spectrum. That's get you banned fast.

Isn't hydroquinone the stuff that's in tonic water?

Some people use the liquid to lighten the skin. If you have dark blotches, for example, or...Lord knows what.

Alibaba seem to be willing to sell it in anything from 1 kilogramme to vast quantities. I couldn't see anything on its site to advise buyers that unless they gave a lot of information as to its use it would be denied them. Does Alibaba apply similar restrictions to Digitaltruth?

It would seem that provided you give information on its use, Digitaltruth will supply a commensurate amount and I'd assume that once you establish a relationship with such a supplier then repeat orders would be straightforward or would it?

The OP of course might simply be making the point that you should not have to explain what use you intend to make of the substance.

No. That's quinine, a very different chemical.

NIOSH did a very extensive study of hydroquinone in the seventies because some thought it might be a cancer risk. The best statistician and epidemiologist in the public health service was responsible for the report, which found no verifiable risk. It's use is pretty well concentrated in the photographic industry, which means it may become expensive in the future.

I think I have seen it on Photograohers formualary site as requiring a DEA form to prevent it being used for drug use of something. Not sure what the staus is as they won't ship it to Canada anyway.

I have found no such restriction on PF website nor with the company I usually buy from.

I think I know what this is about. The FDA wants to ban hydroquinone in skin lightening creams. Texas has already banned its use for this purpose. There have been a number of systemic poisoning cases caused by people who use too much of the cream or making their own. I don't think it has anything to do with the DEA.

There was a fairly recent article on skin lightening creams and their abuse in cultures where one's status is directly correlated to the lightness of their skin. Their abuse is widespread in parts of Africa. Several serious poisonings in South Africa. Evidently recent immigrants to the US have brought this problem to the US. Hydroquinone can be absorbed thru the skin to cause serious poisoning. It can interfere with the hemoglobin in the blood and its ability to carry oxygen.

Hydroquinone is widely used as an ingredient in dyes. A lot of hair dye kits sold in the USA contain it.

Neurological effects of Hydroquinone include;
•Headache
•Tinnitus
•Dizziness
•Delirium
•Muscle twitching
•Tremor and convulsions
•Nausea, vomiting, and the production of green to brown-green urine may also occur.

Hydroquinone may be irritating and corrosive to the skin, eyes, and mucous membranes. Jaundice (yellow tint to skin caused by liver damage) may be noticed.

I wouldn't mind me a little delirium and muscle twitching, but you can keep the rest of those.

Only handle D76 (or similar) with rubber gloves...
If you are on a well and septic dispose as toxic waste.

I think they want us milling around emotionless, and with no purpose in Diversityville, with blithering empty smiles on our faces.


Just checking, but is it the Bilderberg Group, the NWO or the Space Lizards who want that?

Hydroquinone is proving to be difficult to source in the UK in small quantities - The few places that do stock it are getting more and more expensive.
Recently found out that Borax is now a "restricted" chemical and should not be sold to the general public. This EH list also includes Boric Acid and other borate derivatives which is making it difficult to source the chemicals we need for many developers. But hey, there is always someone on ebay willing to flout the rules :wink:

Around here Borax is a washing aid you can get in just about any grocery store and Boric Acid is used to kill cockroaches. You can get both in 50 pound bags without any issues at farm supply stores.

Well, where paul_c5x4 is (and I am - i.e. the UK) isn't round where you are.

The availability of chemicals to the general public simply isn't the same as the US in many parts of the world.

Considering my first name (Muhammad), it would be interesting if I were to order online! :wink:

Hi Paul: IIRC, Adox's owner told in a recent JCH interview about a potential banning (or, at least more restricted use) of hydroquinone due to some environmental concern. He also mentioned that such restriction would be quite bad for B&W film industry. Perhaps they are related.

Bests,
