Swim ordered his MHRB last night  should be here for friday. Swim was in b&q today and bought 500g of concentrated caustic soda, the guy in the shop said that its pure NaoH and nothing else. My question is has anyone else used this b&q brand concentrated NaoH and is it good stuff or is there a better alternative? Thanks.

Is it NaOH dissolved in water? If yes, what is the amount? Is there any indication in the label (e.g. 20%NaOH)? "concentrated" means nothing. It may be concentrated enough to make a good drain unblocker (usually 4-10%NaOH) but a concentrated drain unblocker is not concentrated enough for soap making (usually around 30%). Or is it crystals? Is it a powder/pellet kind of thing? In that case the term "concentrated" does not apply. 100% NaOH is 100% NaOH. Need to calculate between salts and freebases? Click here!

It's a granulated powder, the only ingredient that the label mentions is caustic soda so im assuming its pure NaoH, thanks.
