Benzoyl peroxide


Persistence. Benzoyl peroxide is degraded in the environment.
Bioaccumulation. Benzoyl peroxide has low potential for bioaccumulation.
Toxicity. Benzoyl peroxide has very high acute toxicity.
Risk. The use of Benzoyl peroxide (sales data Sweden 2019) has been considered to result in moderate environmental risk.


This summary information comes from Fass.

Detailed information

Fass environmental information

Fass environmental information for Duac (benzoyl peroxide, clindamycin) from GlaxoSmithKline (downloaded 2022-06-30).


Persistence: Ready biodegradation = 83% 20 day MITI Test, OECD 301C.

Bioaccumulation: Log Pow = 3.43. Since log Kow < 4, the substance has low potential for bioaccumulation.

Acute toxicity: There are data for 3 trophic levels, lowest Green Algae (Selenastrum capricornutum) 70 microg/L.


PPEC/PNEC is based on sales data in Sweden in year 2019. PEC/PNEC = 1,20 which gives the risk moderate.
