longevity

[rsdavis]

I just found out that my soap formula has a longevity rating that is less it should be. Is there anything I can add to increase this?

Longevity (and other qualities) are an estimate and usually are taken only slightly into consideration by experienced soapers. Normally, soft oils will give you a lower longevity on the scale, so using harder oils like shea butter, palm oil, tallow, etc, will give you a harder bar that lasts longer. That's not that the soap will go bad; a lower longevity means it melts faster in the shower for example.
