Write the composition of hand sanitizer?
Answers
Consumer alcohol-based hand sanitizers, and health care "hand alcohol" or "alcohol hand antiseptic agents" exist in liquid, foam, and easy-flowing gel formulations. Products with 60% to 95% alcohol by volume are effective antiseptics. Lower or higher concentrations are less effective; most products contain between 60% and 80% alcohol.
In addition to alcohol (ethanol, isopropanol or n-Propanol), hand sanitizers also contain the following:
additional antiseptics such as chlorhexidine and quaternary ammonium derivatives,
sporicides such as hydrogen peroxides that eliminate bacterial spores that may be present in ingredients,
emollients and gelling agents to reduce skin dryness and irritation,
a small amount of sterile or distilled water,
sometimes foaming agents, colorants or fragrances.
