1. Where, having carried out an evaluation under Article 26(1), a market surveillance authority finds that, although a detergent or surfactant is in compliance with this Regulation, it poses a risk to human health or to the environment, it shall require the relevant economic operator to take all appropriate measures to ensure that the detergent or surfactant, when placed on the market, no longer presents that risk, to withdraw it from the market or to recall it within a reasonable period laid down by the market surveillance authorities and which is commensurate with the nature of that risk.
