Understanding the Data

MoS (Margin of Safety)

NOAEL ÷ Systemic Exposure. EU requires MoS ≥100 for safety. Higher = safer.

Dermal Absorption

Percentage absorbed through skin. Lower = less systemic exposure = safer.

Sensitization Rate

Percentage of people who develop allergic reactions. >1% = significant concern.

EU vs US Status

EU has stricter cosmetic regulations (1223/2009). US FDA lacks pre-market approval.
