ABHR efficacy revisited: influence of alcohol level and product application volume
نویسندگان
چکیده
Methods Efficacy studies were conducted according to ASTM E1174 or with modifications to the hand contamination procedure as follows: For ASTM E2755 studies, hands were contaminated with 0.2 ml of a concentrated challenge suspension to reduce soil load and eliminate post contamination hand wetness commonly associated with testing per E1174. For the “contact contamination” procedure hands were contaminated by touching an agar surface seeded with the challenge bacteria, a process that transfers minimal soil and moisture to the hands.

The relative influences of product volume, delivery format and alcohol concentration on dry-time and efficacy of alcohol-based hand rubs
BACKGROUND Alcohol-based hand rubs (ABHR) range in alcohol concentration from 60-95% and are available in a variety of delivery formats, such as rinses, gels, and foams. Recent studies suggest that some ABHR foams dry too slowly, thereby encouraging the use of inadequate volumes. This study investigates the influence of product volume, delivery format, and alcohol concentration on dry-time and ...
