Safety
Safety Profile
Methylal (Dimethoxymethane) has not undergone specific safety assessments by key regulatory bodies such as CIR, SCCS, or FDA for cosmetic application. While general toxicity is considered low, it is identified as an irritant to the skin and eyes, and its vapors can irritate the nose and throat. Skin contact may also lead to dryness.
