In general, no. We neither perform sensitization tests on humans nor on animals – that is, tests that look for allergic responses.  But we do carry out skin irritation tests on humans, which check for temporary redness, dryness, itching when in direct contact with a substance. Our absorbent hygiene products (that’s your towel, tampon, liner or period panty) follow strict procedures to ensure that they are safe and gentle on your skin. Our Essity Global Supplier Standard prohibits the use of any substances recognized as allergens, except where the products contain perfumes, in which case they are clearly labelled. However, these perfumes are thoroughly assessed to make sure they’re safe for their intended use.
