Hydrogen peroxide – where in Melbourne?

I'm trying to locate some strong hydrogen peroxide (H202<50%). My old supplier sells it in bulk quantities and I only require a litre or less.

Google threw up Rustin's A & B bleach (the B component being peroxide) and Woodworking Warehouse in Braeside are listed as Rustin's stockists, but when I rang about it, they didn't know what I was talking about and wouldn't order it in for me.

Does anyone here work with the stuff, or know where I can purchase a small amount?

I don't know if it a silly suggestion but have you tried hairdressers or hairdressers supplies.
Cheers,
Jim

Small amount? You don't have much hair left then ... ?

Try a chemist perhaps. Or ask at a surf shop.

Hairdressers (ladies probably best) would be the most likely source.

Thanks chaps, but AFAIK, the stuff that hairdressers use is a lot less than 50% and it contains too many other ingredients. From memory, the stuff in the supermarkets is no stronger than 15% or 20% and I don't know that a chemist would require anything stronger than that either, but I will ask.

a hairdressing supply place will have in in a variety of dilutions, right up to 50%.

A great deal has changed in the last half century plus but we used to use it in the labs at school. Perhaps that might give a lead.
Cheers,
Jim

Maybe Selbys laboratory supplies.
If they still exist .

kev.

going to be hard as its an oxidizing agent ,and they only sell small quanities due to terrorist concerns . :2tsup:

Herself picked up a bottle of 'stuff' from a hairdressers' emporium this afternoon and it's the "strongest available" according to the girl who stated it was "forty volts" (it reads '40 vol' on the label). I take that to mean it's 40% by volume which should do. It has a litany of other ingredients including perfume! I'll see in a day or ten how it works out.

The regulations for storing and transporting peroxide changed a few years ago and I think it was indeed to make it more difficult for individuals to purchase peroxide. It's not a hassle for anyone in a business that uses regular bulk quantities, but is very inconvenient for the likes of little ol' me.

Thanks everyone for your help. :thyel:

20 Volume is the common strength sold in pharmacy. 20 Vol is 6%

The stronger strengths can burn the skin (shows as white areas) so gloves should be worn. The treatment is to rub Glycerin (now called Glycerol) into the area.

Dammit! I should have known that. That means the bottle of stuff I got today is only 12%. That's nowhere near strong enough to do what I want.
