Applicant's summary and conclusion
- Conclusions:
- Log Kow for Ammonium glycolate estimated by KOWWIN v1.68 (US EPA) is -4.25.
The substance is an organic salt freely soluble in water, which dissociates into ammonium and glycolate ions within the environmentally relevant pH range (5-7). KOWWIN considers ammonium glycolate an "ion pair" compound and gives a corresponding estimate; effectively, the estimate for ammonium glycolate is an estimate for ionized glycolic acid. Log Kow for non-ionized glycolic acid estimated by KOWWIN v1.68 is -1.07.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
