Weigh all ingredients carefully and prepare each phase in a separate heat-resistant measuring cup.

Heat phase A (sweet almond oil, Olivem 1000 and cetyl alcohol) and phase B together in a water bath until both reach 75 degrees.

Weigh phase B again and top up with water until you reach the recorded weight. Do all phases have the same temperature? Then turn off the heat.

Add the mixture of phases C and D and stir gently until everything is well combined.

Check the pH; it should be between 5.0 and 5.5. This pH is not only the best for your skin, but also ensures that the preservative can work optimally. Use a 10% solution (in demineralized water) of citric acid to lower the pH or a 10% solution of baking soda (in demineralized water) to raise it. Always add a maximum of 1 drop at a time, stir well and wait at least 1 minute before measuring again. As a guideline: with 100 grams of mixture, 1 drop changes the pH by approximately 0.1 to 0.15 pH units on average.

Mix well before pouring the cleanser into a squeeze or pump bottle.
