The Art of Perfumery, and Methods of Obtaining the Odors of Plants

SECTION IX. EMULSINES. From soaps proper we now pass to those compounds used as substitutes for soap, which are classed together under one general title as above, for the reason that all cosmetiques herein embraced have the property of forming emulsions with water. Chemically considered, they are an exceedingly interesting class of compounds, and are well worthy of study. Being prone to decomposition, as might be expected from their composition, they should be made only in small portions, or, at least, only in quantities to meet a ready sale. While in stock they should be kept as cool as possible, and free from a damp atmosphere.
