Quinton Action Plus Nasal Spray is a hypertonic saline nasal spray made from 60% natural cold-microfiltered seawater and 40% spring water, producing a 100 mL solution of approximately 2.1% sodium chloride. It is formulated by Quicksilver Scientific as part of the Quinton line of marine therapy products.

The seawater raw material is processed by cold microfiltration, following the original protocol developed by French physiologist and biologist René Quinton. This process preserves the integrity of the mineral components naturally present in seawater, yielding a hypertonic solution that contains up to 78 elements and trace minerals from the periodic table in varying proportions.

Action Plus is designed for acute nasal use, recommended for pre-operative nasal surgery, occasional cold symptoms, and seasonal discomforts to support nasal and sinus passages. It supports nasal and sinus passage wellness and healthy breathing. The product is preservative-free and hypoallergenic, and is suitable for adults and children 6 years of age and older.
