Vinyl laurate does not show a effect on daphnia when administered up to a concentration of 200 mg/l (nominal).
The acute toxicity of Vinyl laurate to Daphnia magna was determined in a
48 hour static test in accordance with OECD Guideline 202. Daphnia. The
study encompassed two treatment groups: one control and the water phase
of a supersaturated stock suspension of nominal 200 mg/L after treatment
in a separatory funnel was tested (no concentrations above the
solubility limit of the test item in the used test medium were tested to
avoid physical effects of undissolved test item onto Daphnia). Each
treatment group contained 20 individuals. The immobility of the
Daphniawas determined in a static 48-hour test by visual controls after
24 and 48 hours. The samples of the freshly prepared and aged (48 hours
old) test medium were analysed via TOC-method. After 48 hours of
exposure no immobilization of the test animals was observed in the
control and the test item concentration of 200 mg/L. All validity
criteria were met. The quantification of the test item in the test media
was not possible. Due to the low water solubility of the test item the
concentrations of test item in the test media were below the limit of
quantification of the analytical method.The toxic effect of the test
item Vinyl laurate to Daphnia magna was assessed in a static limit-test.
The 48-hour EC50 value was > 200 mg test item/L.
