One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 2915-53-9, Name is Dioctyl maleate, formurla is C20H36O4. In a document, author is Api, A. M., introducing its new discovery. Recommanded Product: Dioctyl maleate.
RIFM fragrance ingredient safety assessment, pentanoic acid, 2-methylbutyl ester, CAS Registry Number 55590-83-5
The existing information supports the use of this material as described in this safety assessment. Pentanoic acid, 2-methylbutyl ester was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from readacross analog ethyl 2-methylbutyrate (CAS # 7452-79-1) show that pentanoic acid, 2-methylbutyl ester is not expected to be genotoxic and provide a calculated MOE >100 for the repeated dose toxicity and reproductive toxicity endpoints. Data from read-across analog isoamyl acetate (CAS # 123-92-2) show that there are no safety concerns for skin sensitization under the current declared levels of use. The phototoxicity/photoallergenicity endpoints were evaluated based on UV spectra; pentanoic acid, 2-methylbutyl ester is not expected to be phototoxic/ photoallergenic. The local respiratory toxicity endpoint was evaluated using the TTC for a Cramer Class I material, and the exposure is below the TTC (1.4 mg/day). For the hazard assessment based on the screening data, pentanoic acid, 2-methylbutyl ester is not PBT as per the IFRA Environmental Standards. For the risk assessment, pentanoic acid, 2-methylbutyl ester was not able to be risk screened as there were no reported volumes of use for either North America or Europe in the 2015 IFRA Survey.
