About

This is a 7 day primary irritation patch test. This study investigates the irritation potential of Next Science MIS Wound Irrigation Solution under standardized conditions compared with an inert control (normal saline) and a known irritant, 20% sodium dodecyl sulfate (also known as sodium lauryl sulfate [SLS]) solution in deionized water [DI] water) on intact skin of healthy human subjects.

Full description
