A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.

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.

Sodium Citrate is the sodium salts of citric acid. In skincare, it is used to alter pH levels and acts as a preservative.
Sodium Citrate helps maintain the pH of a product. Normal pH level of skin is slightly acidic (~4.75-5.5). The acidity of our skin is maintained by our glands and skin biome. Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.
Sodium Citrate is a chelating agent. It neutralizes metal ions from water and prevents them from binding to other ingredients. This ensures the other ingredients will not be altered.
