Trolamine, Triethanolamine Salicylate

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Trolamine is the salt formed by combining salicylic acid and triethanolamine. It is used to reduce certain skin stains, remove earwax, prevent radiation-induced dermatitis, as a sunscreen, topical analgesic balm and in cosmetics. Topical application.

At the time of the last update, we found no published data on its excretion in breast milk.

Cutaneous absorption is less than 10% (Hale, Cross 1998 & 1997, Morra 1996), so the levels reached in plasma are very low and passage into breast milk is not likely to be significant.

Trolamine salts may irritate the skin and mucous membranes and cause contact dermatitis.

Do not apply on the breast, or clean the breast and hands well before breastfeeding.


We do not have alternatives for Trolamine, Triethanolamine Salicylate since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
