is made
by combining fats (base oils, either
fixed or carrier) and Lye Solution
(Lye + a liquid of choice) Each oil
type is made up of fatty acid
properties and contribute something
different to the bar of soap.
Knowing the recommended percentages to use in developing recipes is essential because you don’t want something too drying, brittle, moist, or unbalanced.
Saponification is the chemical
reaction between Lye and the fatty
acid molecules in the oil.

How to make Cold process soap

Making your lye Solution and Melting
Down the base oils.

1.Carefully measure out the lye and the water.

2.When combining, ALWAYS pour the
lye into the water. Stir until dissolved and add thermometer. Monitor until solution is at 110 deg. F.

3. Remember to not breathe in any fumes,
and wear your protection equipment.

4.Measure out your oils and microwave
until melted. Stir and add thermometer. Monitor until solution is at 110 deg. F.

5.Measure out your color and your
EO/FO additives, so that they are ready.

Combine the Base Oils, Lye Solution and
Essential Oils/Colorants/Exfoliant

1.Once both mixtures are within 10 degrees of each other and at or below 110 deg. F, you are ready to combine.

2.Place hand mixer in the oil solution and tilt to remove air bubbles.

3.Slowly pour the lye solution into the oils and slowly mix. Use the blender to pulse the mixture until you reach light trace. Should resemble the early
stages of pudding.

4.Mixture will start to thicken. Add in any EO or FO to the mixture. Stir with blender (do not pulse with motor, as this may accelerate trace).

5.Divide your base into other containers for color, or add color directly to the mixture. Stir until combined.6.Pour into mold. Try to work quickly during these
last steps because once trace has
been reached, your mixture will
be hardening more rapidly. Now
you are ready to pour.

De-Mold your soap, cut and let it

1.After 24 hours, you can
remove the soap from the mold.
Make sure that the soap is firm
before you remove it.

2.Cut your soap to the desired size.

3.Place cut soap on a paper bag and let cure for 4-8 weeks. With Castile soap, the cure time is 6 months.4.Soap is
usable after two days, however, the
lye is still active in the soap, so until the water is fully dissipated from the soap, the lye may still be active.

Now your soap is ready!
