I found a recipe in a book that I really want to expand on and make it my main recipe. It's a green tea soap. You're supposed to use green tea instead of water when you mix your lye. It calls for almond oil, avocado oil, coconut oil and olive oil. I ran it through soap calc and it's going to be an extremely soft bar of soap. I'm worried it will be too soft. I plan on using sodium lactate to make it a bit harder, but how much will that really help? I also really want to use this green tea butter from wholesale. The butter is made with almond oil and vegetable oil. Should I subtract a bit of the almond oil from the recipe and replace it with the butter? If I add the butter without adjusting the almond oil will that make the soap too soft? Is there a way to add a custom ingredient on the soap calc? I just don't want the bar of soap to turn to mush in the shower and would like it to last a while. Is there an oil I can add that would harden the bar? I was thinking of adding some palm oil. Can you have too many oils in a soap? Is there a standard limit that should be followed?
