Added to cold process for hardness (1 tsp per pound stirred at trace) or as main ingredient in salt bars (50-100% of oil weight). Salt reduces lather but creates extremely hard, spa-like bars. Can be sprinkled on MP tops. Due to the hardness of the final bar single cavity molds are recommended. Upping the coconut oil in your recipe can help with lather in the final bar. Avoid using epsom salts as they can cause the soap to "sweat."
