Abstract
Quick-drying hand disinfectants containing 2-methacryloyloxyethyl phosphorylcholine-butyl methacrylate polymer (MPC polymer) as a new moisturizer have become commercially available. Therefore, the antimicrobial and moisturizing effects were compared of two new quick-drying hand disinfectants, a liquid preparation and a gel preparation, and four conventional quick-drying hand disinfectants. The two new quick-drying hand disinfectants as well as the four conventional quick-drying hand disinfectants (2 liquid and 2 gel products) killed all eight bacterial species such as methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Pseudomonas aeruginosa within 15 seconds. The six agents were used 5 times/day for 5 consecutive days, and evaluation of the effects on the hand skin showed that the corneal water content decreased after the use of each conventional agent but increased after using the two new quick-drying hand disinfectants. Therefore, these two new quick-drying hand disinfectants are less likely to cause hand roughness, and showed both excellent antimicrobial effects and good moisturizing effects.
