What are the characteristics of hand sanitizer?

Hand sanitizer typically contains alcohol as its active ingredient, usually in concentrations of 60-95%, which effectively kills germs and bacteria. It is often gel-based for easy application and quick drying, and may include moisturizing agents to prevent skin dryness. Additionally, hand sanitizers can come in various scents and formulations, including those free of fragrances and dyes for sensitive skin. They are designed for convenience and are effective when soap and water are not readily available.
