I had a similar thread about this question not that long ago and many of the science geeks gave me a lot of great info on the subject. While water loss is one aspect of cure, certain oils continue to morph and improve over time. Olive oil is one of them. The soaps that take 4-6 weeks to cure (and that includes olive oil, just at a much lower percentage), usually stop losing their water weight at about the same time.
Now I'm sure the geeks (and I say that term with the utmost love and respect) will give you more info on what oils other than olive oil need more time to morph and develop as well as percentages. What I have been doing is taking my loaf ends and cutting each one into quarters and testing them each week...I have learned a lot about the qualities of the soap and the differences in the cure...and it's just fun to try them out! Kinda like watching your baby take his first steps, then walk, then run...
I'll try to find it for you, but I'm not sure it will answer all of your questions. In a very general sense, a bar that is not cured will be harsh and drying, will not lather well and will melt quickly under water. The loss of water will improve melting times, the harshness and lathering are the parts of curing that are separate from the water loss. My guess is that those factors are the results of the saponification process and the chemical interaction of the lye and the oils...if I'm wrong I'm sure someone will chime in with the correct information.Could you give me the link to that thread? I guess the big question is what does a bar that is not done cure feel like?

Is the link. I got it from the bottom of the page.
I am beginning to think that a new shapers first batch should be liquid soap. That way they have some soap to use, and they don't mind giving the bar soaps a proper cure
If you use less water is the cure time shorter?
