Ingredients Explained
These ingredients are found in both products.

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Alcohol Denat. is an alcohol with a denaturant property. It is created by mixing ethanol and other additives. It has a low molecular weight and will evaporate quickly. This helps other ingredients become better absorbed and dry once applied.
Alcohol Denat. is volatile and may cause irritation. It helps draw out natural oils in skin and dry out your skin.
One study from 2005 found adding emollients to propanol-based sanitizer decreased irritation.
Alcohol is antibacterial by nature. This can help preserve products and increase their shelf life.
Other types of astringent alcohols include:

Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.
