Longevity Percentage help

[naturalnegeste]

What's the ideal percentage for longevity for soap I'm playing around on SoapMakingFriend.com and I can't get anything above a 15% I noticed that the Babassu oil upped the percentage opposed to castor oil pulling down the percentage any advice is welcomed...

Oils and fats high in oleic acid will produce a soap that is not long lasting.

Thank you and I finally figured it out I want to do a non animal fat soap and I being a newbie replaced the wrong oils thinking it was an equal replacement for another oil but now I got it down and finally got a recipe I can try out!!!

Oils high in palmitic and stearic will increase your longevity:

Lard, Tallow, Soy (fully hydrogenated) 'wax', Palm Oil, Shea Butter, Cocoa butter are the most common.
