Sodium Hydroxide purchasing question

[TBandCW]

While looking around again for a local source of citric acid, I came across a place that also sells sodium hydroxide for water treatment purposes. It says:
Sodium Hydroxide (caustic soda) 20%-50%.

My thought is that I need pure (99%) sodium hydroxide for CP. Am I correct?

Yeah, I'm scratching my head, because what is the other 80%-50%? Maybe call and ask if they sell it to soapers?

Is it a solution?

I would not recommend using that.

I wouldn't use that either.

I used to get mine from the local hardware store, granular 100 percent lye. But no matter what I did, it had a lot of static and granules bounced all over my kitchen.

Been ordering for several years from essentialdepot.com and it's behaved perfectly, no bouncing escaped granules. They usually specials for free shipping or large discounts. From what others have said, The Lye Guy is a good source too.

I second paillo. You may also find a chemical company locally (I have one) and they may sell lye in flakes.

Salesman said it is in flake form. I told him I need pure 99% lye. He is checking into for me.
