Mix the lye into the water.
Mix your oils together. If coconut oil is in a solid-state, heat until melted. I melted it in the microwave in 30-second increments.
The lye mixture should be cool enough to handle, Pour into oil mixture.
Once you've mixed well, use your emulsion blender. Be careful not to splatter. Mix for several minutes until it starts to look like mayonnaise. You have now reached "trace." Mix in essential oils and any other ingredients, ie oatmeal, rose petals, lavender leaves, or other exfoliants.
Pour soup mixture into molds. Tap gently to even out.
Cover soap mixture. If your soap mold did not come with a cover, wrap with a towel. Let set 24 hours.
After 24 hours, you can unmold soap and cut.
Let cure for 30 days. For the first week, flip your soap over each day. This will help your soap dry out. After that, flip weekly. I stored on a baking sheet and wrapped it in wax paper.
