On June 25, 2025, the European Chemicals Agency (ECHA) launched a consultation on the Belgium proposal for harmonized classification and labeling (CLH) of Propylparaben, a preservtive. This consultation is open until August 22, 2025.
Propyl 4-hydroxybenzoate (CAS No.94-13-3; EC No.202-307-7; INCI: Propylparaben) is an ingredient listed in Cosing, with the functions: Preservative, Perfuming.
It is regulated by Annex V/12 (Preservatives) of European Cosmetics Regulation 1223/2009, which limits its maximum concentration in finished products to 0.14% (for the sum of the individual concentrations) and to 0.8% (for mixture of authorized parabens). It is also prohibited in leave-on products designed for application on the nappy area of children under three years of age.
It is not currently listed in Annex VI of European CLP Regulation 1272/2008.
Belgium proposes to classify the substance as follows.
