The Challenge

Globally, propellants like HFC-134a are being phased out due to their high global warming potential (GWP), plus there are growing safety concerns about flammability. When Mission Pharmacal Company decided to introduce a spray product to treat diaper rash in babies and the elderly, it needed a propellant that could meet criteria for nonflammability, low environmental impact, formulation compatibility and reliable application performance – in addition to long-term regulatory compliance.

The Solution

After attempting to convert an existing diaper rash zinc ointment into a spray product, Mission Pharmacal turned to Formulated Solutions, its experienced development partner, for assistance. As described above, Mission Pharmacal set high standards as criteria for success: the spray had to perform with “elegance” and reliability, and be safe and environmentally friendly. Formulated Solutions recommended Solstice® Propellant due to its nonflammable properties, VOC-exempt status, and ultra-low GWP of less than 1 – in addition to its excellent performance and regulatory staying power. Today, Solstice® Propellant is successfully powering all of the company’s brands of Dr. Smith’s® spray products.

Choosing Solstice® Propellant

Prior to accepting the Mission Pharmacal project, Formulated Solutions had already been on a quest for ultra-low GWP propellants. High on its list was Solstice Propellant – the only non-flammable, ultra-low global warming potential (GWP) propellant available today. After subjecting Solstice Propellant to rigorous internal testing to validate everything from performance and safety to manufacturing qualifications, the company was confident Solstice Propellant could meet performance needs.

“With Solstice Propellant, we were able to create a diaper rash spray formulation for Mission Pharmacal that made a great system-in-a-can, actually improving product performance while meeting important needs for nonflammability in the marketplace,” said Eric Dann, president of Formulated Solutions. “From a manufacturing standpoint, we were able to easily convert an existing aerosol line to Solstice Propellant with minimal modifications – saving time and money.”
