Regulation (EU) 2023/1545, published in July 2023, amends Annex III of the EU Cosmetics Regulation. It expands the list of fragrance allergens that must be individually declared on the ingredient label from 26 to more than 80 substances. The deadline for new products placed on the EU market is 31 July 2026. Products already on the market before that date may remain available until 31 July 2028. The declaration thresholds have not changed: – Leave-on products: individual declaration required when concentration exceeds 0.001% in the finished product. – Rinse-off products: individual declaration required when concentration exceeds 0.01% in the finished product.
