Re sap values and hardness of soap

[Guest guest]

I think that it has more to do with the innate qualities of the specific oil

you are using. The sodium hydroxide reacts with the oil to produce say

sodium olivate and glycerine. The chemical composition of oils is different

and there may be more or less glycerine depending on the individual oil I

suppose. The actual quantitiy of lye only makes a difference as to the

amount of oil which gets saponified. Not a very scientific explanation I'm

afraid but the best i can do ......
