Applicant's summary and conclusion
- Conclusions:
- Based on the information available it can be concluded that the substance is not hazardous following short-term expsoure via the dermal route and has a NOAEL of 1,000 mg/kg bw/day.
- Executive summary:
A reliable study performed by Bernard et al. (1998) was identified in the literature. This study included examination of the reproductive organs of treated animals allowing to investigate the effects of the substance to fertility. It is concluded that PPG-2 myristyl ether propionate is not hazardous following a short-term exposure via the dermal route and has a NOAEL of 1,000 mg/kg bw/d. This is supported by the historical uses of the substance is cosmetics and personal care products.
