Frequently asked questions
- Is toluene sulfonic acid safe for baby skin?
- No reproductive/developmental classification or mechanistic evidence specific to infants. However, the ingredient has harmonised classifications for skin and eye irritation (H315, H319) and respiratory irritation (H335) per ECHA Annex VI; infants (0–3 yr) have higher dermal absorption and more sensitive skin, so exposure score is increased by +1 to e=2. Concern for local irritation/corrosivity to baby skin is primary hazard rather than systemic developmental toxicity. Sources: ECHA Annex VI (harmonised CLP), ECHA classification data, PubChem.
