Acetonitrile is a colorless chemical solvent primarily known for its industrial applications in chemical processes. It’s considered highly toxic to humans and is not generally used in skincare products meant for direct application to the skin because it can cause irritation and harm.




Acetonitrile is a manufactured chemical and not found in natural sources.


Acetonitrile can be tolerated on the skin in small quantities, but it can cause irritation and potential harm with prolonged or repeated contact because of its toxicity and ability to penetrate the skin.


Acetonitrile does not have skincare benefits and has harmful effects on health.


Toxic Effects

Acetonitrile can be absorbed through skin and may enter the bloodstream. High concentrations or prolonged exposure to acetonitrile can potentially lead to systemic effects or toxicity.

Irritates Skin

Acetonitrile is known to irritate skin. Direct contact with acetonitrile can lead to redness, itching and discomfort. Prolonged or repeated exposure may result in skin irritation and dermatitis.

Causes Dryness

Acetonitrile has the potential to strip skin of its natural oils and lead to dryness and potential flakiness.

Causes Contact Dermatitis

Acetonitrile exposure can result in contact dermatitis, which is characterized by redness, itching and sometimes a rash. This can occur more frequently with undiluted or concentrated acetonitrile.
