According to the study, which substance is toxic to aquatic life and can affect fertility?
|
Butylphenyl methylpropional |
|
This substance is considered toxic to aquatic life and can affect fertility, which is why it has raised concerns about its safety and use in products like cosmetics and personal care items.
|
substances like Limonene, Alpha-isomethyl ionone, Linalool, and Phenoxyethanol are allergens commonly found in cosmetic products, but they do not have the same impact on the environment and reproductive health as Butylphenyl methylpropional does.
