Abstract

The existing information supports the use of this material as described in this safety assessment. Butyl lactate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog ethyl (L)-lactate (CAS # 687-47-8) show that butyl lactate is not expected to be genotoxic. Data on read-across materials butyl alcohol (CAS # 71-36-3) and lactic acid (CAS # 50-21-5) provide a calculated margin of exposure (MOE) > 100 for the repeated dose and reproductive toxicity endpoints. The skin sensitization endpoint was completed using the dermal sensitization threshold (DST) for non-reactive materials... (More)

The existing information supports the use of this material as described in this safety assessment. Butyl lactate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog ethyl (L)-lactate (CAS # 687-47-8) show that butyl lactate is not expected to be genotoxic. Data on read-across materials butyl alcohol (CAS # 71-36-3) and lactic acid (CAS # 50-21-5) provide a calculated margin of exposure (MOE) > 100 for the repeated dose and reproductive toxicity endpoints. The skin sensitization endpoint was completed using the dermal sensitization threshold (DST) for non-reactive materials (900 μg/cm2); exposure is below the DST. The phototoxicity/photoallergenicity endpoints were evaluated based on ultraviolet (UV) spectra; butyl lactate is not expected to be phototoxic/photoallergenic. Data on butyl lactate provide a calculated MOE >100 for the local respiratory endpoint. The environmental endpoints were evaluated; butyl lactate was found not to be Persistent, Bioaccumulative, and Toxic (PBT) as per the International Fragrance Association (IFRA) Environmental Standards, and its risk quotients, based on its current volume of use in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]), are <1.
