ABSTRACT
Objective: To measure the skin temperature after application of a new skin protectant intended for incontinence-associated dermatitis (IAD), compared with a commercial product with an analogous cyanoacrylate-based chemistry. Approach: Twelve healthy human volunteers received an application of the new product on one thigh and of the comparator on the other thigh. An infrared camera using ThermaCAM™ software imaged the skin and measured the temperature at the skin surface over time to characterize the thermal cure profile induced by the products on the skin. Results: The new product led to a drop in skin surface temperature (endothermic reaction), whereas the commercial product displayed an exotherm and a slight rise in skin surface temperature. Innovation: Cyanoacrylate-based chemistries come in various formulations, differing in the side chains and additives used. They are liquid monomers that polymerize after application, and this polymerization is accompanied by an exothermic reaction that can be perceived as an unpleasant warming sensation, especially on compromised skin. A new formulation was designed to mitigate this rise in temperature. Conclusion: The new skin protectant may potentially be more comfortable for IAD patients, since it causes a drop in skin surface temperature instead of a rise during the curing process that follows application.
