who helps formulate for healthy hands?
we do.
When soap and water are not available, hand sanitizers are a convenient option to reduce the number of active microbes on hands. The choice of rheology modifiers is important as it influences the sensory experience, ease of application, and delivery of actives, all of which encourage product use for healthier hands.
featured ingredients for foaming hand sanitizers.
Ashland offers a range of ingredients for enhancing the texture and sensory of foaming hand sanitizers. Foam formats – both non-aerosol and aerosol - are a desirable format for killing germs on hands.
