Hand sanitisers are a type of disinfectant that uses chemicals to kill germs and bacteria. They come in the form of gels, liquids or foam. Antibacterial wipes and bactericidal soap are also available. Hand sanitisers are especially useful in situations where it’s not possible to wash hands with soap and water.
Professional hand cleaning products are developed for engineering workshops and other specialised work settings. They come in liquid or paste form. Hand cleaners allow fast and thorough cleaning of heavily soiled hands without using aggressive solvents. They can be used to quickly cleanse the skin of lubricants, grease, tar, paints and similar contaminants. They are skin-friendly and usually contain substances such as aloe vera, lanolin and jojoba oil for skin conditioning.

Hand sanitisers use chemicals to dissolve the protein layer of viruses and bacteria, killing them. Depending on their active ingredient, hand sanitisers can be classified as alcohol-based or alcohol-free.
- Alcohol-based. These sanitisers contain at least 60% ethyl alcohol or 70% isopropyl alcohol. The active ingredient immediately denatures proteins, neutralising certain types of microorganisms.
- Alcohol-free. Usually based on disinfectants or antimicrobial agents. They are as effective as alcohol-based sanitisers at eliminating germs.
Using hand sanitisers is better for the skin barrier than repeatedly washing hands with soap and water. Excessive hand washing can lead to rashes, dermatitis and dryness. Hand sanitisers, to the contrary, evaporate quickly and have little impact on the skin barrier. However, some products may contain fragrances or dyes that can cause skin irritation.
One important drawback of hand sanitisers is that they are relatively ineffective against certain types of germs, such as spores and non-enveloped viruses. They also cannot clean the skin properly if applied on dirty hands. For these reasons, hand sanitisers are not a substitute for washing with water and soap.
