found a great reference on soap properties

i have found a great reference on how soap structure influences the soap properties. . . hardness, lather, solubility (soap mush) etc. i can't just post the whole thing and i'm busy making a summary for myself as i am going through it. . . trying to figure it out. . . it should be ok to post that i think?
It is from the book i posted about in the library section by Luiz Spitz. . . if you come across this book somewhere have a look. . .

Thanks Riaan, I am always looking for soap books to read
