Stable Pressurized System Including Plastic Container And Active(s)-Containing Composition

摘要

Pressurized compositions propelled by a pressurizing component (preferably a propellant such as compressed gas) and further including at least one active ingredient, at least one high molecular weight nonionic surfactant, and water which is a major component of the composition and is at least substantially ion-free and/or salt-free (preferably ion-free and salt-free), wherein the composition is stored in and dispensed from a plastic pressurized container. The plastic is preferably PET or PEN. The composition has a pH of about 4 to about 8.5. The composition can include as active ingredient(s), one or more of a fragrance component, an odor eliminating compound, an insecticide, an antimicrobial, and a disinfectant.

主权项

1. A pressurized article comprising
(a) a pressurized container for storing and dispensing a composition, wherein said container includes a spray nozzle and a plastic body for containing said composition; and (b) said composition for storing in and dispensing from said container comprising
(i) at least one pressurizing component;(ii) at least one active ingredient;(iii) at least one high molecular weight nonionic surfactant having greater than 8 carbon atoms;(iv) water as a solvent carrier in an amount to serve as a major component of said composition, wherein said water is at least substantially ion-free and at least substantially salt-free; wherein said composition has a pH of about 4 to about 8.5, and is present in said container under an initial pressure of about 80 to about 150 psig at 50° C. (122° F.).
