DISCUSSION Not only Industry and the SCCS, but also other stakeholders expressed their views on the safe use of parabens in cosmetic products. In order to provide an as complete as possible picture on all the available information, the individual points of view of all parties are also summarized below. 4.1 VIEW OF THE INDUSTRY The current Industry submission uses the following argumentation to declare all parabens safe for use: 1. The choice of the reproduction NO(A)EL value: Industry emphasizes that the Oishi (2001) study is not reliable and that the CTFA/Colipa study (Hoberman et al. 2008) is well performed. One of their arguments is that the SCCP (2008) acknowledged the scientific value of the new study. 2. Toxicokinetic aspects related to the risk assessment of parabens: Industry presents a large pharmacokinetic study in the rat using different routes of exposure (Aubert 2009). A major conclusion is that in the rat, independent of the route of exposure, parabens are quickly; EFFECT=_____________________________________________ 20 4.

At the time of the 2005 SCCP opinion, the only in vivo study in which the lowest (and only) dosage level of butylparaben did not cause any adverse effect on the male reproductive parameters measured, was a rat assay in which the ester was subcutaneously administered to neonatal rats for 17 consecutive days. Out of this study a NOEL of 2 mg/kg bw/day could be extracted for butylparaben (Fisher et al. 1999). Since Industry considered both the NOEL of 2 mg/kg bw/day for butylparaben (Fisher et al. 1999) and the NO(A)EL of 10 mg/kg bw/day for propylparaben (Oishi 2002) an overestimation of the reproductive hazard of the parabens under study, the applicant decided to repeat the Oishi assay in male rats with a more robust study design. Butylparaben and methylparaben were chosen as test compounds as they were considered to bracket the chain lengths of all parabens used and to allow interpolation of the results for ethylparaben and propylparaben. The full study report was submitted to the SCCP in 2006 and was later published (Hoberma","endpoint":"reproductive toxicity","ingredient":"s, toys, textiles,","loael_value":"","noael_unit":"mg/kg bw/day","noael_value":"10","page":10,"route":"","species":"rat","study_id":"sccs_o_041_noael_005"}
