In the classes I teacli; moisturizing creams rank as one of the favorite formulas to both make and use. Students are always thrilled to see the transformation of oil and water into rich, delightfully fragrant emulsions. Creams combine the hydrating effects of water and the nourishing, lubricating effects of oil into one product. The Basic Cream For- mula yields about 19 oz., enough to share with family and friends. You can choose to omit the essential oils from the following formulas if you are sensitive to scents. Since these creams are made without chemical stabilizers or preservatives they can be quite perishable, especially if you omit the essential oils. The best solution is to use them up quickly. However, you may want to refrigerate your creams to increase their shelf life. Note that cold temperatures can cause the consistency to change; the water may bead onto the surface of the cream, and slight granulations sometimes appear. Don’t worry about such changes in appearance, since they don’t alter the effectiveness of the cream. Because creams are made from natural ingredients, they may at times develop a bit of mold on the surface. If this happens, you can simply scrape off the affected portion and use what remains. If at any point your cream gives off a rancid odor, however, be sure to discard it and make a fresh batch, since rancid oil produces toxins. When applying these creams use a little at a time, as they are very concentrated and a little goes a long way. To make the following formulas, please refer to Directions for Creams in Techniques and Definitions chapter.
