Abstract
A concentrated reduced dosage spray pump delivery system for dispensing fluids containing actives and volatile organic compounds with reduced emissions of the volatile organic compounds is disclosed. The system includes a housing storing a concentrated fluid containing volatile organic compounds and an effective component, wherein the effective component is concentrated within the fluid. The system also includes a spray pump in fluid communication with the concentrated fluid containing the volatile organic compounds such that the spray pump dispenses the concentrated fluid at a reduced dosage per pump stroke. The combination of the concentrated fluid containing volatile organic compounds and the reduced dosage per pump stroke reduces the emission of volatile organic compounds, while the quantity of actives applied per square area of application surface substantially remains the same.
