Can you use Denatured Ethyl Alcohol for skin disinfection, or will the denaturants penetrate the skin & be toxic?

EDIT: obviously methanol is toxic, but I'm seeing other denaturants listed instead:

I see there are several chemicals that can be used as denaturants.
2-propanol, 2-methyl (CAS 75-65-0)
tert-Butyl alcohol
denatonium Benzoate (CAS 3734-33-6) as a bitterant.

and probably others.

EDIT: this is good info but I'm still wondering about the amount used:

Safety

The Cosmetic Ingredient Review Expert Panel (CIR) concluded that safety of ingredients containing denatured alcohol should be predicated on the safety of the denaturants used since dermal application or inhalation of cosmetic products containing these ingredients will not produce significant systemic exposure to ethanol. The Panel considered that the adverse effects known to be associated with alcohol ingestion do not suggest a concern for Alcohol Denat. or SD Alcohols because of the presence of the denaturants.

The safety of the alcohol denaturants Denatonium Benzoate, t-Butyl Alcohol, Diethyl Phthalate, and Methyl Alcohol were reviewed by the CIR Expert Panel in 2008 and found to be safe as used.

Despite the approval of denatured alcohol by the CIR Expert Panel, the safety of this ingredient in skin care products is controversial. When high concentrations of denatured alcohol are used in the formulation of skin care products, this ingredient can cause drying and irritation.

Denatured alcohol can also cause erosion of the skin’s surface layer, leading to a weakened skin barrier. However, according to FutureDerm, if lower concentrations of denatured alcohol are used, this ingredient may simply be acting as a degreasing agent, making for a better texture of the skin care formulation.

Ultimately the safety of Alcohol Denat. in cosmetics and personal care products depends on both the type of denaturant and also the concentration that is used to create the formulation.
