The substance 4-(3-ethoxy-4-hydroxyphenyl)butan-2-one (CAS Number 569646-79-3), which has been assigned the name Hydroxyethoxyphenyl Butanone (HEPB) under the International Nomenclature of Cosmetic Ingredients, has the function of preservative and skin conditioning. It is currently not listed in Regulation (EC) No 1223/2009.

The Scientific Committee on Consumer Safety (SCCS) concluded in its opinion of 7 April 20172 that, under an aggregate exposure scenario, HEPB can be considered safe when used as a preservative in rinse off, oral care and leave-on cosmetic products at a maximum concentration of 0,7 %. The SCCS also concluded that more evidence would be needed to exclude eye irritation.

Following concerns raised by several Member States on HEPB as a potential eye irritant and additional scientific data submitted to it by the applicant, the SCCS concluded in its opinion of 5 March 20193 that, under an aggregate exposure scenario, the use of HEPB as a preservative in rinse-off, oral care and leave-on cosmetic products at a maximum concentration of 0,7 % is safe with regard to eye irritation.

In light of the opinions mentioned above and in order to take into account technical and scientific progress, HEPB should be allowed for use as a preservative in rinse off, oral care and leave-on cosmetic products at a maximum concentration of 0,7 % in ready for use preparation.

Regulation (EC) No 1223/2009 should therefore be amended accordingly.

The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on Cosmetic Products,
