4-isopropyl-m-cresol

Endpoint summary

Additional information

The substance is a crystalline solid at ambient temperature, with negligible amount of inhalable particles. In water, it is moderately soluble, with limited dissociation in alkaline media, and no surface-active properties anicipated. It is of low volatility, and has low potential for bioaccumulation.

It is not classified as hazardous with regard to physical hazards (flammability, explosivity, self-reactivity, oxidising properties).
