Ive read up on neem oil. It sounds amazing I hear it STINKS, I have some on the way....I want to use it in a base for a dog shampoo bar and for ppl as well, I live in the country and am attacked by mosquitoes in the summer.....Question is does anyone here use it?? Being newer to this soap making hobby.... what are your opinions..and what % do you think I should incorporate...I was told you can use it up to 20%.........also ive heard i should add at trace to help retain its benefits etc...... just looking for advice from a more experienced soaper!!!! Thanks!!!!!
