Some have said they add good ingredients to a melt and pour base to make their soaps. One thing you have to remember- the melt and pour is NOT natural; it has a ton of chemicals, some of which are bad for you. (see my blog on my website and my note on fb titled "It Has What in It?." 
Also, melt and pour base soap is made with lye, as is any soap. Lye is necessary to make soap, so if someone tells you their soap does not contain lye, it's a lie. No lye, no soap, no lie.
