On a water bath, melt and mix the ingredients except the menthol, water, propyl p-hydroxybenzoate, and perfume. Then add the menthol, which dissolves readily. Now add slowly, with constant agitation, a small portion at a time, hot water with the methyl p-hydroxybenzoate dissolved in it, until the first-formed water-in-oil emulsion inverts to oil-in-water. Then add the remaining water, hot, rapidly to volume, with agitation. When cooled down somewhat, stir in the perfume. The ingredients can be varied slightly to individual likes and dislikes. The finished product can be modified by reheating on a water bath, more of melted oil-phase ingredients or more hot water added, stirred, and then allowed to cool. Lilac perfume blends well with the predominant menthol odor, but other scenting agents may also be used. Antiseptics can be incorporated by dissolving them in either the oil or the water phase, depending on solubility. For example, 1% of hexachlorophene ("G 11," Sindar) can be dissolved in
