Francis, yes there is no law that dictates that a castile soap requires a 6 month cure, but IMO any good soaper will tell you that it most certainly benefits from it and does get better with a longer cure. I would NEVER use or sell a castile soap that had not cured for at least 6 months. I will also cure a bastile soap for months too since it also has a high OO content and will benefit from a longer cure time. In fact, I just put out on the shelves of my store a bastile soap I made last June and half the batch is already gone because my customers know how nice a properly cured bastile or castile soap is. I once even cure a castile soap for 2 years just to see how it would be after a super long cure. It was divine and sold out in a matter of days! When I do make any castile soap, it sells out quickly. Anyone that has made a castile soap and taken the time to cure it properly will tell you there is a noticeable difference from it and a castile soap only cured for 1 month. I know this from my experience. Whether to make a bastile or castile soap is really a matter of preference. Castile soaps are wonderful for all ages, especially a more mature skin type since they are wonderfully conditioning on our older, dryer skin. A longer cure time will help with what some people will characterize as a slimy feel, but will not completely alleviate it. Castile soaps are said to be some of the mildest soaps out there too. Bastile soaps can be great too and made with the right oils and butters, the slimy feel can be alleviated or cut down and the amount of bubbles increased. But, if you decide to make a castile soap, don't do yourself or your customers a disservice and not cure it for the proper time. Trust me, if you do cure for the proper time, you'll be have a wonderfully mild soap. That being said, I like them both but will always cure a castile soap for 6 months.
