Mechanism of Action
As a solvent, Trichloroethane exerts a defatting action upon skin contact. This mechanism strips natural lipids from the epidermal barrier, potentially leading to significant irritation and dryness. While skin absorption occurs, inhalation represents a more prominent route of exposure.

Formulation
Stability
1,1,1-Trichloroethane is a colorless liquid prone to decomposition at high temperatures, emitting toxic chloride fumes. It reacts slowly with water to form hydrochloric acid. Formulations typically incorporate additives to inhibit its decomposition and prevent metal corrosion.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded 1,1,1-Trichloroethane to be safe as a cosmetic solvent; however, an industry survey indicates it is not used in cosmetics. Its production was banned globally by the Montreal Protocol in 1996 due to its classification as a Class I ozone-depleting substance by the U.S. EPA. The FDA deems its use in aerosol cosmetic products non-essential, making its practical application in cosmetics non-existent and largely prohibited due to significant environmental and regulatory concerns.

Verdict
Trichloroethane should be actively avoided in skincare due to its significant environmental impact as an ozone-depleting substance, its historical prohibition in many applications, and its high potential for skin irritation and dryness.
