- NOTE: If you are making these products for sale, good manufacturing practices recommend you wear a hairnet, gloves and a mask. We also recommend a clean apron.
- This project and these instructions have been written for someone who has experience making soap and knows the potential dangers due to working with sodium hydroxide. It will not outline safety methods of working with dangerous chemicals, it is simply a soap recipe for advanced soapmakers.
- Put on your protective gear. This is very important since you will be working with an extremely caustic base that can and will burn you if you touch it. Noxious fumes are also released from the exothermic reaction that occurs when you mix the sodium hydroxide with water.
- Wear a face mask or leave the vicinity quickly after stirring the sodium hydroxide into the water. If you get any lye on your skin just wash it off quickly with copious amounts of cool water.
- Prepare the lye solution by weighing the water and lye into separate containers. Pour the lye into the water, carefully mix in a well-ventilated area and set aside to cool while you prepare your oils.
- Melt the solid oils (coconut oil and shea butter) either by microwave or stovetop. Melt just until melted and no more.
- Add the liquid oils (olive oil, rice bran oil and avocado oil) to melted oils to bring the temperature down. Add the essential oils to the oil mixture and stir.
- Once the oils and lye have cooled down to under 90°F, pour the lye solution into oils and blend until just emulsified. If you blend to a thick trace, you might not have enough time to swirl the soap.
- Next, we need two cups. Pour about 12 ounces of soap into each cup. Color one with lavender pigment and the other with teal green pigment. Stickblend briefly to get the color dispersed. Don’t stickblend long or your soap will setup too fast.
- Pour the uncolored soap into the mold. Holding each color up high, rotate drizzling the colored soap into the mold. The higher you hold the pouring container, the deeper it will go into the uncolored soap. End with the pouring container close to the surface of the soap to make color sit on the surface.
- Use a spatula to swirl the soap.
- Allow your soap to harden overnight and unmold the next day. If the soap is too soft, allow soap to harden for 48 hours.
- Cut and cure for a minimum of four weeks.
