Take a look at our special edition DISINFACTS Green! https://www.hartmann.info/en-corp/disinfacts/2023-2/index.html Taking small steps towards more sustainable hygiene The healthcare system is one of the largest emitters of CO2, with the majority of emissions being attributable to anaesthetic gases [3] or imaging procedures [4], for example. Disinfectant wipes only play a subordinate role here. Nevertheless, for example in Germany, switching from PET wipes to cellulose-based wipes could save around 5500 tonnes of CO2 every year. Visualisation of skin hydration after frequent hand disinfection using Capacitive Contact Imaging A recent study by the HARTMANN SCIENCE CENTER, BODE Chemie GmbH, a company of the HARTMANN GROUP, investigated the skin moisturising effect of a hand disinfectant with a comprehensive skin care complex. Capacitive Contact Imaging (CCI) was used as a method to measure and visualise skin hydration in comparison to conventional corneometry. In addition to established parameters such as pH, transepidermal water loss (TEWL) and dermatological assessments, the effects of a two-week application of a hand disinfectant foam on skin condition were investigated. Regular daily use of the product resulted in an improvement in skin hydration without any intolerance. The results obtained by CCI and corneometry were consistently comparable and showed a significant increase in skin hydration after the two-week application period. CCI visualised the increase in skin hydration, demonstrating its potential as an additional method to assess and demonstrate the effect of hand hygiene products on skin health [1].
