  • Foot balm as a moisturiser/product category for regulating salicylic acid?

    Posted by MariaSibon on April 4, 2023 at 7:55 am

    Dear all,

    I am puzzled with EU restrictions on salicylic acid use in cosmetics, in Annex III it is stated that up to 2% can be used in leave on products except
    body lotion, eye shadow,
    mascara, eyeliner, lipstick,
    roll-on deodorant (see picture below).

    Is my foot balm the same as body lotion? It is not intended to be use onthe body, but on feet and heels. Salicylic acid is a common active in these products does it have to be restricted up to 0,5%, while a face serum can use up to 2%?

    It does not make sense to me.

    What is your opinion? Which category I should follow for a boot balm?

    My opinion is b. I will also discuss with my safety assesor.

    My understanding is 2.0% topically applied anywhere is the limit. Weirdly, wart removers are allowed up to 17.0%.

      Yes, my understanding is that wart removers is under pharmaceuticals regulation.

      Any dermaceutical, cosmeceutical or cosmetic with medical claim, still need to comply with cosmetics regulation…It is really a grey area….

      Regarding salicylic acid safety assessment @fareloz made a really good comment that did not think initially. See here: https://chemistscorner.com/cosmeticsciencetalk/discussion/salicylic-acid-and-the-kiddos/#

      The factor of surface area plays a great role during toxicological assessment. e.g. face serum is allowed to have 2% but body lotion only 0.5%, because of the larger area of application and therefore absorption. Maybe the same goes for warts because it is applied only in a small spot?

      Salicylic acid and the kiddos…….
