Longevity

[JLOWE]

Hi! I cannot seem to get longevity up above 25. What are some ways to increase this? Fats that I use often are Lard, coconut oil, palm oil, OO, shea butter, also have canola, avocado, castor, jojoba, hemp, sweet almond. Thanks in advance.

In general, harder oils (solid at room temperature) make harder longer lasting soap. Olive oil soaps are great, but they tend to not be longlasting. Lard and tallow are great, as is palm oil and coconut oil along with butters like shea butter.
