Washing of hand is utmost important to reduce the microbial contamination in hospital, laboratories, toiletries and at home. However the water used may not be safe all the times and therefore the use of soap and detergents have been introduced in addition to the water. Still in recent times the hand sanitizers have been introduced in the market which claims to have great bactericidal activity and safe for use. The hand sanitizers available in the market are both alcohol based and non-alcohol. The alcohol based hand sanitizer claims to kills 99.99% microorganisms including the most resistant form. The alcohol free hand sanitizer viz. povidone-iodine, benzalkonium chloride or triclosan have persistent antimicrobial activity for a prolonged period and claim to be effective in killing microorganism. In the present study the effectiveness of hand sanitizers both Alcohol / non-alcohol based are tested against the standard Staphylococcus aureus and E.coli. The evaluation of the hand sanitizer is done by Kirby-Bauer technique. The non-alcoholic sanitizer viz. Alemlaq (Alkyl Dimethyl Benzyl Ammonium chloride) was found to be more effective than other alcoholic sanitizer against Staphylococcus aureus. Similarly Lux (Sodium laurate) was found to be more effective than other alcoholic sanitizer against E.coli.
