This invention relates to methods of formulating steroid pheromones as novel stable emulsions. These emulsions can be used for administration of the steroid pheromones to living organisms such as humans or pigs in place of current organic solvent or pressurized aerosol formulations that present hazards in both shipping and application. Uses relating to pigs are in stimulation of sexual maturation, diagnosis of the onset and timing of oestrus in female pigs, and inducing boars to accept dummy sows. The water-based emulsions can include 5α-androst-16-en-3-one and 3α-hydroxy-5α-androst-16-ene for administration to pigs. The use of water-based emulsions eliminates the need for formulation of the steroid pheromones in organic solvents, delivery of these pheromones as pressurized aerosols, and following the precautions required to reduce hazards during shipping and handling. The water-based emulsions allow for treatment of living organisms where a liquid organic solvent formulation or aerosol of the pheromones might be harmful to the organism or a substrate.
