Table 2 Classification scheme for acute and chronic aquatic ecotoxicity of the considered polymers (based on [118, 119] a, adapted)

From: Environmental fate and effects of water-soluble synthetic organic polymers used in cosmetic products

  Ecotoxicity
No Low Moderate High
Acute LC50 or EC50  > 100 mg/Lb  > 10 to ≤ 100 mg/L  > 1 to ≤ 10 mg/L  ≤ 1 mg/L
Chronic NOEC or EC10  > 10 mg/Lc  > 1 to ≤ 10 mg/L  > 0.1 to ≤ 1 mg/L  ≤ 0.1 mg/L
  1. aThe classification schemes of Wagner et al. [118] and UN [119] were developed for aquatic toxicity data for algae, crustaceans, and fish
  2. bHighest concentration that has to be tested according to OECD test guidelines 201 [120], 202 [121], and 203 [122]
  3. cHighest concentration that has to be tested according to OECD test guidelines 211 [123] and 210 [124]
