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.

Ashland offers both synthetic and nature-derived options to meet the challenges of thickening hydro-alcoholic hand sanitizer gels. In addition, there are a range of performance additives to add allure.
