|Title:||LOW VOC, SUNSCREEN SPRAY COMPOSITION CONTAINING A HYDROPHOBIC, FILM-FORMING POLYMER|
Stable, water-based formulations containing high levels of water insoluble UV protectants/insecticides are provided herein as sprayable microemulsions containing a film-forming polymer, e.g. Agrimer® VEMA ES 425 [poly(methyl vinyl ether-maleic acid monobutyl ester)]. The polymers are solubilized either by partial neutralization with a base, or by emulsification with appropriate emulsifiers. These formulations produce single phase, micro- or mini-emulsions (particle size < 1 micron) on dilution with water. The formulations are useful as UV protectants in veterinary use, for protection of UV-labile insecticides, and for 'pour on' applications.
