Homebrew PCBs

I’m looking for higher concentration H2O2 to try my hand at Toner Transfer
board etching.

I did some internet searches for Beauty Supplies (and then Hydrogen Peroxide
on their website) but I came up with a bewildering array of creams, etc. but
nothing like “30% H2O2 in gallon size”, etc.

Can someone give me a Product Name, Brand Name, and/or product category
(like: “bulk hair bleach”, etc.) that can help me ‘cut to the chase’ when
I’m talking to Beauty Supply places or doing Internet searches?  What
exactly do I ask for?  

(BTW:  I’m in Tampa, Florida, USA.  Are there any list members near me?)
 
Cheers,
