This lesson will go over common additives and the way that they can affect your finished soap.
The total amount of fluid additives that can be added to MP Soap Base ranges from 4-6% depending on the base. This includes fragrance oils, essential oils and liquid colorants. Most of the time you will be adding about 3% of fragrance oil or essential oil, so this leaves you with 1-3% of other liquid that you can add. Fragrance Oil / Essential Oil:
3% is the general usage rate for MP Soap Base.Extra Oil or Butter:
1% or 1 teaspoon per pound of soap. If you add liquid oil or butter to soap base it will reduce the lather. It can also cause issues with separating or seeping, so try it in a small test batch first. Adding extra liquid oil, such as avocado oil, olive oil or sweet almond oil, will also soften the soap. Your soap won’t harden up as usual.
It is recommended to select a base formulated with the oil and butters that you want as opposed to adding them yourself, as the formula properties can negatively change. Click Here

How to Use Exfoliating Additives
Sometimes it can be hard to suspend exfoliating additives in MP Soap Base. They can sink or float depending on the base and the additive. There are two ways to combat this issue.
1. Use a Suspension Soap Base
. Suspension Soap Bases have been specially formulated, providing for suspension of additives.
2. Mix and pour at a very low temperature; close to the MP Soap Base's melt point. The soap base will be thicker at this point, and will sometimes suspend the additives.Usage Rate
Typically you can start with 1 teaspoon of an exfoliating additive per pound of soap base and go up or down from there depending on the amount of exfoliation that you require.
Stay away from adding sugar or salt to your MP Soap Base, as both attract moisture and can cause your soap to weep and become mushy.
