Hand Sanitizer Content for Hospital Use

Optimal Alcohol Concentration

The Centers for Disease Control and Prevention recommends alcohol solutions containing 60%-95% alcohol for hand sanitization in healthcare settings, with higher concentrations being less potent because proteins are not denatured easily in the absence of water 1
Ethanol 60%-95% is classified as a Category I agent (generally safe and effective) by the FDA for use in antiseptic handwash products 1
The World Health Organization suggests that isopropanol 70%-91.3% is widely used, with 60% isopropanol adopted in Europe as the reference standard for alcohol-based hand rubs 1

Alcohols have excellent germicidal activity against gram-positive and gram-negative bacteria, multidrug-resistant pathogens (MRSA and VRE), Mycobacterium tuberculosis, and various fungi, as reported by the Centers for Disease Control and Prevention 1, 2
Ethanol has greater activity against viruses than isopropanol, which is crucial in healthcare settings, according to the Centers for Disease Control and Prevention 3
For nonenveloped viruses (like rotavirus, adenovirus, and rhinovirus), a 60% ethanol formulation can reduce infectivity titers by >3 logs, as stated by the World Health Organization 3

Adding 1%-3% glycerol or other skin-conditioning agents can reduce the drying effect of alcohol on skin, improving compliance, as recommended by the American Hospital Association 4
Alcohol-based rinses or gels containing emollients cause substantially less skin irritation and dryness than soaps or antimicrobial detergents, according to the Centers for Disease Control and Prevention 4
The volume of product applied is critical - insufficient volume results in inadequate antimicrobial activity, as reported by the World Health Organization 5

For routine hand hygiene in healthcare settings, alcohol-based hand sanitizers should be applied to all surfaces of the hands and rubbed until completely dry, as recommended by the American Heart Association 6
The CDC recommends that alcohol-based hand sanitizers should be rubbed over all surfaces of the fingers, hands, and wrists until the sanitizer has dried (approximately 30 seconds) 6
Alcohol can prevent the transfer of healthcare-associated pathogens more effectively than handwashing with plain soap and water when hands are heavily contaminated, according to the Centers for Disease Control and Prevention 3

Using insufficient volume of product - this significantly reduces antimicrobial efficacy, as reported by the World Health Organization 5, 7
Applying alcohol-based sanitizer to wet hands - this dilutes the concentration and reduces effectiveness, according to the Centers for Disease Control and Prevention 7
Using alcohol-impregnated towelettes, which contain limited amounts of alcohol and have effectiveness comparable only to soap and water, as stated by the American Hospital Association 4
Selecting products with strong fragrances that may be poorly tolerated by healthcare workers with respiratory allergies, as recommended by the Occupational Safety and Health Administration 4

The Centers for Disease Control and Prevention recommends alcohol-based hand sanitizers should contain 60%-95% alcohol (ethanol or isopropanol) as the primary active ingredient for optimal antimicrobial efficacy 8
Higher alcohol concentrations (>95%) are less effective because proteins are not denatured easily in the absence of water 8, 9

When chlorhexidine is added to alcohol-based solutions, 0.5% concentration is optimal for providing persistent antimicrobial activity without excessive skin irritation 8, 10
Alcohol-based preparations containing 0.5% chlorhexidine gluconate demonstrate persistent activity that equals or exceeds that of chlorhexidine gluconate-containing detergents 11

Alcohols have excellent germicidal activity against gram-positive and gram-negative bacteria, multidrug-resistant pathogens, Mycobacterium tuberculosis, and various fungi 8
Adding 0.5% chlorhexidine to alcohol solutions provides residual antimicrobial activity that pure alcohol formulations lack 8, 10
The combination of 70% isopropanol with 0.5% chlorhexidine gluconate has demonstrated a 6.0 log reduction of HIV in 15 seconds, showing excellent virucidal activity 9
