What this means in practice
For pregnancy skincare planning, this ingredient should not be viewed in isolation from the full INCI list. A product can contain one flagged ingredient and still differ substantially from another product containing the same ingredient, depending on concentration, vehicle, other actives, and use pattern. That is why this page gives ingredient-level context while the app remains the best place to run full product-level checks.
For breastfeeding, we use the dedicated breastfeeding columns in our ingredient data where available and apply practical handling advice in a conservative way. That usually means paying attention to application area, avoiding breast or nipple contact when relevant, and re-checking the exact formula currently in your hand because labels and regional formulas can change.
