PURELL® Brand CLEAN RELEASE™ Technology (CRT) HEALTHY SOAP™ is a refreshing foam formulation that provides a better handwashing experience and gives people added peace of mind. Research shows that 84 percent of people were satisfied with the overall cleanliness of facilities with PURELL® products. Using scientific research to maximize effectiveness against germs while caring for hands, the PURELL® brand developed CLEAN RELEASE™ Technology that reaches into skin's cracks and crevices 2X better than regular soap to wash away more than 99% of dirt and germs. By collaborating with a leading dermatologist to identify the most common causes of severe skin irritation—harsh preservatives and antimicrobials—this hypoallergenic formula is free of these ingredients and better for skin. Plus, CRT soaps are made with naturally derived ingredients. The transparent refill allows you to easily monitor soap levels with just a look, which means there's no need to open the dispenser. Each refill is factory sealed to help eliminate the risk of contamination. Refill bottles are easily recyclable.
