Do I really NEED a Lye Calculator?

2 Oct

What do you think?

It’s definitely a lot easier to use one.

But  as long as you have a few numbers you can manual calculate it! 

Want to know how?

Keep reading……

( if you have ANY questions please contact us)

The first thing you NEED to know is the SAP# or Saponification number which is needed to know how much lye to use to convert the oils / butters into soap. **Your vendor should be able to supply you with that information.

and

the Second thing you NEED to know is the weight of the oils you’ll be using.

We’ll use these Oils, Sap Numbers & Weights:

Coconut Oil

Sap # .183

Weight 10 ounces

______________________________________________________________

Palm Oil    

Sap#     .142

Weight 8 ounces

______________________________________________________________

Olive Oil  

Sap# .135

Weight 12 ounces

______________________________________________________________

This is how I write it out on paper:

SAP #’s        OILS             WEIGHT

.183                Coconut                     10

.142                  Palm                         8

.135                   Olive                       12

_______________________________________________________________

Now you just NEED to multiple:

.183 X 10 = 1.83

.142 X 8 = 1.14

.135 X 12 = 1.62

_______________________________________________________________

Then ADD the totals together:

1.83

+1.14

+1.62

= 4.59 (THAT’S How much LYE you’ll NEED!) BUT WAIT!!!!!

_______________________________________________________________

You’ll want to leave some kind of a buffer so lets SUPER-FAT 5%.

Take the amount of LYE needed…

4.59 and multiple it by .05 —– Looks like this: 4.59 X .05 = .229 (let’s round it off .23)

Then Subtract .23 from the Lye needed 4.59

4.59 – .23 = 4.36 (who-wee we got the answer, this is the amount of lye you’ll need to use )

You’ll NEED 4.36 ounces of lye for the recipe above with a 5% Super-Fat!!

Now you can run it through the LYE CALCULATOR!

    That was really easy to understand. However, how do you work out the amount of H2O?How do you calculate H2o @ 33%, 38% etc This is really interesting!

      Hi Christine,

      Sorry it took me so long to get back with you!!!! You’ll use between 6 – 6.5 ounces of water per pound of oils/butters.
      Thanks for stopping by,
      Pam
