It also recommends using hand sanitizer when it is inconvenient to use soap and water. The best method of cleaning hands is still soap and water.

Aside from alcohol, the active ingredient that most non-alcohol hand sanitizers feature is benzalkonium chloride.

Consumers will also be able to find both scented and fragrance-free hand sanitizers. Some common fragrances used in hand sanitizers include lavender, vanilla, coconut, and citrus scents.

Why is my hand sanitizer sticky?

If your hands become sticky after using hand sanitizer, it’s usually a result of a certain ingredient or a bad formulation, as not all hand sanitizers are the same.

The most common cause for stickiness is Aloe Vera, which is commonly found in advanced gel formulas. Aloe Vera is typically added to hand sanitizer to help moisturize the skin, but too much of it can leave your hands feeling tacky.

Another leading cause is poor formulations, which is the result of supply chain disruption from the Coronavirus. As hand sanitizer is in mass demand, it is being produced at unprecedented levels, resulting in specific shortages of main ingredients like carbomer.

Carbomer is typically one of the main ingredients in hand sanitizer that turns it into a gel. Since there is currently a shortage of this ingredient, manufacturers are substituting carbomer for other ingredients like Hydroxyproplycellulose. These replacement ingredients, while work in there intended purpose, can cause yours hands to feel sticky once dried.

If your looking for a hand sanitizer that won’t leave yours hands feeling sticky, be sure to look at the ingredient list. Select one that doesn’t use aloe Vera and make sure it includes carbomer (or Carbopol™).
