tea tree oil

Is there some way, like looking at the fatty acid profile to calculate or otherwise know the levels of absorption of different oils? ... Alternatively, is there a website with comparative scores on key characteristics like absorption, clean feeling, etc? If not, which is a faster absorbing oil...

I made a CP tea tree oil soap that began crumbling when I took it out of the mold. I'd like to know what I did wrong to cause it (am thinking I mixed it at too high a temp) and is there anyway to save/redo? It's an olive oil and coconut oil soap. Thx! Connie

I'm a brand new soap maker and wand to make an olive oil based soap with tea tree oil. How much oil do I put into a 2 lb loaf that will be very aromatic and make your skin tingle? Thx!
