Goat Milk Soap:

My Eugene, OR source for goat milk is : GreenHerb Dairy Goats

  • 12.5 oz olive oil
  • 12.5 oz palm oil (or purified beef tallow)
  • 10 oz coconut oil
  • 5 oz sweet almond oil
  • 17.5 oz goatmilk
  • 5.5 oz sodium hydroxide
  • 3 Tablespoons lavender essential oil
Wear goggles and rubber or latex gloves during the entire process to protect yourself from the lye. Small children should be out of the area.

Prepare molds. 2 quart milk containers with the tops opened all the way works well for beginner soapers.

Put goatmilk in freezer. After it's frozen blend it until it's like ice cream. Very slowly add the lye to the mushy milk stirring constantly. This takes around 15 minutes. Bring to a temp of 92 - 97 degrees F. Note: Starting off with extremely cold milk prevents scalding.

Melt the oils together gently, bring temp to 92 - 97 degrees F. (Cool in a pan of cold water).

Carefully add the milk/lye solution to the fats. Stir stir stir. Stir until a light trace develops over the surface of the solution. Tracing is when you can see your stir marks on the surface. You can draw lines and see a faint trace of them for a few seconds. This may take up to 2 hours. Or you can buy a stick blender (mine is made by Braun) and blend for one minute. The blending makes the NaOH and fat molecules come into contact with each other much more rapidly than stirring.

When tracing has occured, add the lavender e.o. and stir it in.

Pour into molds. Insulate the molds in a box with blankets over and around and under the box. Or, use styrofoam peanuts around and under the molds, and bubble plastic on top. Let sit in a warm place over night.

After the soap has hardened (between 12 and 48 hours) remove it from the molds and cut the soap into soap size pieces. The soap will be a nice tan color. Note: At this point the soap may have an unpleasant, sharp odor. This will disappear after 1-2 weeks.

Let the soap cure for at least 4 weeks before using.

The Overnight Rebatching Method:

This rebatching method is for soap that has aged over 1 week. (Any soap "younger" than that can be rebatched easily with no added liquid since it hasn't dried a whole lot.)

Either grate the soap or put it in a food processor. Then put the shavings in a pan. To that add enough liquid to coat the shavings:
2 - 4 Tablespoons water per 1 lb. of soap (even all veggie) has been successful for me. Some people find that adding milk in place of water for all veggie soaps works better than water. I also like to use aloe vera gel as a rebatching liquid.

Now, here's the trick: At this point cover the pan and let it sit out at room temp overnight, or for 8 hours. After that time you will see that the shavings have absorbed the liquid and are soft. There should be no extra water in the pan. With the pan covered, put this pan in another pan of slowly boiling water. This is my fake double boiler system. Stir the chips about every 5 minutes, for around 15 - 30 minutes, until you have a nice translucent gel. Voila! This is IT! The gel is thick, not watery. Now you can add fragrance and coloring. I add around 2 teaspoons of scent per pound of rebatching soap. Stir, cover for around another 5 minutes or so and spoon/pour into your mold.

The top of the rebatched soap will be "bumpy". This is normal. After the soap has hardened, you can cut off the bumpy layer if you like. I cut it off and use it for hand washing my dishes.

A hint for getting a good consistancy for small rebatches is to use a clean soup can as a mold. Be sure the bottom of the can is able to be opened with a can opener. After the soap is in the mold, tap it down on a hard surface a few times to settle the soap and then place the can in the pot of very hot water. Don't let the can float. Cover the pot for about a minute then carefully (without burning your fingers!) remove the can from the pot. The soap will have become much more uniform. After the soap has hardened, open the bottom of the can and push the soap through. You will have to hold the can under hot water to soften the sides of the soap before the soap can be pushed through.

You can also use cup size plastic yogurt containers as molds. I've been able to float these in the hot water as they won't tip over.
