Description of key information

In accordance with column 2 of REACH Annex VII, the determination of the partition coefficient in n-octanol/water (required in section 7.8) was waived, as disodium persulfate is an inorganic salt. A default log Pow of -1 was used for risk assessment (EUSES v2.1 default).

Additional information

In accordance with column 2 of REACH Annex VII, the experimental determination of the partition coefficient in n-octanol/water (required in section 7.8) was waived, as disodium persulfate is an inorganic salt. All substances of the persulfate category are inorganic salts, sharing the same persulfate anion moiety. A default logPow of -1 was used for risk assessment (EUSES v2.1 default).
