The longer you wait before selling your soaps the better. Do you know what your soap will be like in 6 months, because it won't be the same as it is today. Hopefully, it will still smell as good, still be the same color & not smell of rancid oils or be slimey. Hopefully, it will have aged into a wonderfully scented, mild soap.
At 6 months, I had a few batches go rancid & develop DOS. I had to figure out what went wrong.
It takes time for some problems to surface. Don't be too quick to sell your soaps. If you don't know what ash is yet or what the tongue test is, you're rushing into selling without all the knowledge you need. Do you know what DOS looks like?
Better you find the DOS or rancidity, or slimey soap, or a scent that faded after 2 months or a color that morphed from a pretty pink to a dull grey after a few months than a customer.
Just because a soap comes out of the mold looking & smelling fantastic doesn't mean it will be that way in 6 months. Only time will tell.
I cringe knowing I gave my niece a beautiful lavender soap that's losing it's scent & smells oily. Nothing I did wrong, but a bad EO that is, over time, degrading the soap. I'm grateful I never made anyone pay for that soap!
Do you know what the recipe you're using, the oils, scents & colors are going to be like in 6 months?
I'm not trying to be rude or discouraging, but ash is a pretty common thing in the soapmaking world, so I wonder what else you might not be aware of.
