Dispersing agents for use with hydrofluoroalkane propellants

摘要

Vitamin E acetate, C3-linked triesters, glycerin, t-butanol, and transesterified oil/polyethylene glycol are effective dispersing agents for use with hydrofluoroalkanes. Effective amounts of the above are effective in suspending medicaments which are useful in inhalation aerosols, and especially meter-dose inhalers.
