Compliance to hand hygiene guidelines is affected by education, availability, time pressure, skin health and worker  acceptance of the dose size.


Assess ABHR foam dose sizes aligned to WHO recommended drying time (20-30 secs) with a variety of healthcare workers considering how repeated use, hand size and years in the job affects acceptability.


197 workers evaluated 3 out of the 4 randomised dose sizes during a central location test at Mount Sinai Hospital, CA. Acceptability of each dose was assessed and rated on their level of agreement with the following statement: ‘this product is ideal for me and my patients’. The number of top box responses for each dose size were analysed.


– 80% scored 1.3mL and 1.5mL as acceptable opposed to 70% for 1.6mL and 1.7mL. 1.3ml was rated significantly higher than 1.6ml and 1.7ml on ideality.

– Dose size acceptability was influenced by hand size – larger hand sizes were more accepting of the doses

– Workers employed by Mount Sinai for less than 3 years were less accepting of the dose sizes than those working at the hospital for 6-20 years.

– 47% of workers felt all 3 of their assessed dose sizes were acceptable.


Testing in isolation does not reflect the effect of repeated use when defining dose size. There is a decline in acceptability after 1.5ml, with 1.3ml being the more favoured dose. Smaller doses may increase hand hygiene compliance. Hand size is an important factor affecting dose size acceptability.


Dr Hines gained his PhD in Chemistry at Oxford University before joining Unilever as an R&D scientist where he worked in product development on numerous well known global brands. John joined Deb (now SC Johnson Professional) as Global Research and Development Director in 2010 and in that role has lead the development and launch of several successful innovations in the world of “professional skincare” from hand hygiene in healthcare
