Soap: The science behind it, the changing
regulatory landscape ahead, and tools and tips
for selecting a soap that’s right for your facility.
Hand hygiene is the primary measure to prevent
transmission of pathogens in healthcare facilities
and alcohol-based hand rub (ABHR) is designated as
the preferred method for performing hand hygiene by
the 2002 Centers for Disease Control and Prevention
(CDC) and the 2009 World Health Organization (WHO)
hand hygiene guidelines. However, soap and water
also plays a critical role in hand hygiene, namely
when hands are visibly soiled or contaminated with
blood or other bodily fluids and when there are
outbreaks of Clostridium difficile or Norovirus.
Because ABHR has been the primary focus for hand hygiene, soap has received less attention in recent
years, and due to limited data around soap, many
healthcare facilities have given less thought to the
type of soap they are using. However, regulations for
antiseptic active ingredients typically used in hand
soap are undergoing revisions and the landscape
of available actives is likely to change soon. These
forthcoming regulatory changes will force many
healthcare facilities to rethink their hand soap choices
and look for technical information that typically does
not exist. Anticipating these changes and arming
oneself with information can help alleviate uncertainty
and simplify future decisions. The purpose of this
paper is to educate infection preventionists and other
key decision makers on the science of soap, help
explain the regulatory changes underway, understand
possible outcomes, provide guidance on how to
evaluate soap products, and decide which soap
is best for a facility.
