Title: koh or noh
Post by: tuftey on October 27, 2011, 07:32:34 AM

I use koh but my freind uses noh I know the drawback of getting rid of glyc when solid
But what else are the plus/minus points about it

O I forgot the price is cheaper I know that and you use less due to the 7/5 factor

I use NaOH because it's cheaper and the soaps settle out under gravity more quickly than KOH.

Plus for me solid glyc is a bonus - the household waste places won't take liquids.
