Abstract

Cosmetics are in principle safe to use. In some cases however, cosmetic products may lead to undesirable reactions, such as itching and erythema. RIVM has set up a monitoring system in which undesirable reactions as well as other allergic reactions caused by cosmetics can be registered (CESES, Consumer Exposure Skin Effects and Surveillance). As in previous years, such reactions are mainly reported after the use of hair products, skin products and make-up, including primarily those products intended to use on or around the eyes. In addition, relatively many hairdressers reported contact dermatitis located on the hands after the use of hair products at their work. Isothiazolinones, a preservative in cosmetics, and fragrances remain the cosmetic ingredients relatively most responsible for allergic reactions. More attention to isothiazolinones is especially important, because these ingredients are also widely used in other consumer and industrial products. As a result, it is difficult for consumers, who are allergic to isothiazolinones, to avoid these ingredients. Ammonium persulfates and PPD remain the most important causative agents for contact dermatitis in hairdressers. As in previous years, allergic reactions to the UV filter octocrylene, which is used in sunscreens, and co/cross polymers, which are used in several creams, were reported. The goal of CESES is to monitor undesirable reactions attributable to cosmetics and cosmetic ingredients to assess whether current EU legislation on cosmetics provides adequate consumer protection. Also, risks for workers can be identified. Consumers can report allergic reactions on the website www.cosmeticaklachten.nl. In addition, participating dermatologists report cases of contact dermatitis to the system when cosmetics are expected to be the cause. Dermatologists also carried out patch tests and, where necessary, tests with specific batch ingredients of the associated cosmetic product.
