Is >98% purity Sodium Hydroxide ok for soap making?

[LeitrimLass]

Hi,
Total novice here. Am currenty getting my supplies together for a first attempt at soap-making. My local hardware store has caustic soda (>98% purity Sodium Hydroxide) which works out alot cheaper than the 99% purity product (which states that it is suitable for soap-making) available on ebay for example. So, my question is, can I go with the >98% product? Is it safe/ suitable for making soap?

Thanks for your help and support
Lorna

depends on what the other 2% is - but probably.

Look up the MSDS sheet for the product, it will tell you what the other 2% is.

It's probably just water but I'd want to check first...

Thanks a mill for that...

I guess if I check the product name, I'll find that sheet on the internet, right?
