This time I added more glycerin, water, and subbed coconut oil instead of cocoa butter. I halved the recipe of the original to make this new one:
WildChildT's Homemade Shaving Cream
(adapted from Better Basics for the Home)
4 oz. grated castille soap
~5 oz distilled water
1 oz. coconut oil
3 oz. vegetable glycerine
Place soap and water in a container, cover and let rest overnight. The next day, melt coconut oil and glycerin in a double boiler. As soon as they are melted, add to soap and blend with a hand mixer until creamy. Mix in essential oils and transfer shaving cream to a lidded container or mug/bowl of choice.
