Look in the Bath & Body section of this forum for lotion advice. Make sure you're preserving your lotions properly. That is essential. Don't even think about selling a lotion that isn't properly preserved with chemicals. There is no "natural" lotion preservative. Also, from experience, I'd suggest testing your lotion formula by letting some bottles sit for 6 months to make sure they stay nice. I had had a wonderful lotion recipe that I had sold for a couple of years. I then made the mistake of buying my emulsifying wax from a different supplier. Well, I had some of my lotions in a flower shop on consignment and after sitting in there for a while, the lotions separated. After that, I began buying a lotion base and I loved it.
If you want to sell soap fast, try melt & pour base. It's worth the money, I think. CP and HP take a long, long time to master. Many months, I'd say. And you owe it to your customers to make a quality product. But with MP, you can sell much quicker and have a quality soap. For me, the cost is also lower to make MP than CP.
