Description of key information
Data for toxicity to microorganisms are available from 4 reliable studies.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 3 000 mg/L
Additional information
Adequate and reliable results on the toxicity of C8-18 and C18 unsatd. AAPB (Coco AAPB) to microorganisms are available.
The toxicity of C8 -18 and C18 unsatd. AAPB to Pseudomonas was investigated in four studies conducted according to national standard methods (DIN 38412, part 8 and part 27) and according to EN ISO 10712, respectively.
The toxicity of C8 -18 and C18 unsatd. AAPB to Pseudomonas putida was investigated in a study conducted according to EN ISO 10712. Pseudomonas were exposed to the test material (10000 mg product/L nominal) for 16 h under static conditions. A 16 h EC0 = 3000 mg active substance/L nominal was determined.
The toxicity of C8 -18 and C18 unsatd. AAPB to Pseudomonas putida was investigated in a study conducted according to DIN 38412, part 27. Pseudomonas were exposed to the test material (10000 mg product/L nominal) for 30 min under static conditions. A 30 min EC0 = 3000 mg active substance/L nominal was determined.
The toxicity of C8 -18 and C18 unsatd. AAPB to Pseudomonas putida Migula was investigated in a study conducted according to DIN 38412, part 8 (Pseudomonas Zellvermehrungshemm-Test). The 16 h EC10 was found to be >10000 mg dry residue/L (nominal) which corresponds to >8450 mg a.i./L nominal assuming a content of 29.6% active matter.
The toxicity of C8 -18 and C18 unsatd. AAPB to Pseudomonas putida was investigated in a study conducted according to DIN 38412, part 8 (Pseudomonas Zellvermehrungshemm-Test; Draft). The 16 h EC10 and EC50 were determined to be 15000 and 17000 mg product/L nominal, respectively. The active matter content is not reported. Assuming an active matter content of 30%, a 16 EC10 = 4500 mg a.i./L and a 16 h EC50 = 5100 mg a.i./L is obtained.
Conclusion
The available data point on a low toxicity of C8 -18 and C18 unsatd. AAPB to Pseudomonas putida (30 min/16 h EC0 = 3000 mg a.i./L nominal).
