Mechanism of Action
On the skin, Methyl Acetate provides a transient anesthetic and cooling effect. Its primary action is as a degreaser, which can disrupt the skin's lipid barrier. Over time, particularly with repeated exposure, it possesses the capacity to exacerbate existing inflammation and may induce new inflammatory responses. This compound also undergoes slow hydrolysis in the presence of water, yielding acetic acid and methanol.

Stability
Methyl Acetate is prone to hydrolysis, particularly in the presence of strong aqueous bases or acids, and at elevated temperatures, converting into methanol and acetic acid. Optimal stability is achieved within a neutral pH range.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed Methyl Acetate safe for use in cosmetics within its review of alkyl acetates. However, the SCCNFP (a precursor to SCCS) opined that while it is safe for nail polish removers, its use in other cosmetic products would necessitate a comprehensive safety dossier due to its inherent toxicity profile. It is classified as GRAS (Generally Recognized As Safe) by the FDA as a food flavoring agent and is also utilized as an excipient in some topical pharmaceutical preparations.

Verdict
Given its high irritancy, degreasing action, and potential to exacerbate inflammation, Methyl Acetate is unsuitable for precision skincare formulations, despite its CIR 'safe as used' status for general cosmetics.
