Sistrum and Hazel - thank you both for your comments.
I would like my tutorial to be both accurate and comprehensive so it's great to have feedback.
Sistrum - With regard to Palm Kernel Oil - I found this helpful (as well as other websites) in considering how single oils perform -
http://www.zensoaps.com/singleoil.htm - nevertheless I have deleted reference to palm kernel oil in my suggested recipes.
Hazel - re the wooden spoons, glitter and pyrex - thanks for pointing this out -amendments made.
With regard to the fragrance amount, 45g per 1000g (4.5%) - I have amended the tutorial to suggest that they insert 30g (3%) into soapcalc (which is the lowest % you suggested) and they should alter that % based on the recommended usage and also state that the FOs should be cosmetic grade skin safe.
Thanks for pointing out rules 16 and 17 in the message board rules that any links/references association/affiliation must be stated. I am only affiliated with the two links at the very bottom of the tutorial where I had stated "do join our facebook group" and "for our soap course...". Because I had used the word "our" that should be sufficient for the reader to be aware that the forum and course is run by me but if you would like me to make this clearer, I'm happy to do so.
All the other links/references (of which, yes there do seem to be quite a few), I can confirm that I have absolutely no interest in or affiliation with.
Thanks again for your comments - it's great to have feedback, share experiences and opinions.
