Where are you Canadians getting your hydrogen peroxide hair "bleacher" in Canada? I went into the largest hair product supplier/reseller in my region today and requested a creamy product with hydrogen peroxide. They said that you must have a license to buy this product. Apparently, the reason is because people were burning themselves with the hydrogen peroxide hair bleacher product so they licensed it. Help! I just pulled out my 20 year old A/C on wheels and all the plastic is dark yellow and was hoping to do my first retorbrite tests on it while the summer is still here.

I think you might have to talk with Natural Resources to confirm what's allowed to de-bromine your plastics.

Hopefully they just limit your amount.

Hydrogen peroxide at a concentration of at least 30%

Ker-boom!

I was reading that for retrobrite, 6-12% is fine. So, looks like I'm not looking for stuff with explosive concentrations.

I went to Pharmaprix (Shoppers Drug Mart) where I found bottles of 30% peroxyde.

Shoppers Drug Mart? I'm guessing that it isn't so simple where I live. I'll take a look at Shoppers though. Is this product in the hair care section? Is it behind the counter? What is the intended purpose of Hydrogen Peroxide 30 volume? And why is it called "30 volume"?

Probably a cream to bleach hair?

I got this in the hair products isle. I also used it without gloves. Other than a very slight and brief burning sensation, I saw no issues. I just wash my hands after and put on some hand moisturizer. No ill effects that I could see.
As for the 30 volume, I would assume that it just implies that it is 30% by volume rather than weight... Like American beer. 😉

Oh and it was on a regular shelf.

I got my stuff at a local indie drug store (Feipoa: PMed you!) There's no restrictions on it at normal concentrations AFAIK. Indian-run pharmacies or general stores are a good bet because they tend to stock a lot of home hair dying products. The supermarket sells whole bottles of liquid H-peroxide too.

You can handle it with your hands, although it'll sting if it gets in a papercut & will dry out your fingers eventually. Peroxide is often used to disenfect cuts & scrapes. It's not dangerous in normal store-bought concentrations. (Don't eat it though.)

It seems that products that contain hydrogen peroxide use "volumes" to indicate concentration. I vaguely recall from my high school chemistry classes that there was a conversion formula to map between volumes and percentages.

For example, 30 volume means it has a content of 9% of hydrogen peroxide:

I went to a Sally Beauty Supply shop a year ago for mine. Salon Care 40. It was in Langford across Millstream from the Costco.
