..on the sap process...sap numbers...superfatting

[Guest guest]

Morning--

...ok--now, you've got me a bit confused with all the 'theories' behind

*when* you superfat!

....I'm going to attempt to put into wards how it was described to me.

 

Each oil/butter has it's own sap number--which refers to, essentially,

the amount of lye it takes to completely saponify it into finished soap.

 

When we imput oils/butters into any lye calc--and use the standard 5%

value for superfatting, it takes that discount and applies it to the

*total* sap value of the oils/butters.

 

So--this means that the amount of lye you've added to your

oils/butters will *only* saponify 95% of the *total* oils/butter in

your formulation--there will not be sufficient lye to 'eat up' the

remaining 5%.

 

Just how much of any oil/butter is left from the beginning sap process

is determined by the nature of each oil, in how it is reacting to the

lye solution, (for example: shea is mostly UNsaponables--it remains

mostly the same as when it went in)...so, you'd end up with more of

*that* butter left, than say, the amount of olive.

 

Reguardless--you actually have no way of *positively* knowing the

exact amount of any remaining un-saponified ingredient, although you

*should* (providing you understand the qualities of each)have a good

idea of what your soap should end up like, from the amounts of each

ingredient you added.

 

So--if you wanted *more* control over precisely *which* oil is

remaining un-saponified, you would add this at a point in *your*

process to ensure this ingredient remains mostly un-saponified

(trace/heavy trace/just prior to pour...etc)

 

I'm thinking I've gotten that right, anyway!

Sorry, but I think I'm going to confuse you more thoroughly, then. lol

 

Interesting theory, but how then, do you explain when you use 100% shea - I've

done that, and it definitely saponifies, thus rending the argument of adding

" unsaponifiables " at trace a moot point. Depending on the temperatures, 100%

shea butter (meaning 100% of the oil, for those who may be easily baffled or

confused) can trace very quickly.

[Dave:] I’m thinking so, too.
