Referenceopen allclose all
SugaNate 160NC D-Glucopyranose, oligomeric, C10-16-alkyl glycosides, 2-hydroxy-3-sulfopropyl ethers, sodium salts gave a positive result (>=60% degradation relative to the COD value) with 84% being reached by day 7 and a maximum of 97% achieved on day 14. It may therefore be concluded that there is a potential for biodegradation under environmental conditions.
The guideline requires that the reference material degrades by at least 60% of its ThOD, and that the blank dissolved oxygen loss does not exceed 1.5mg/l after 28 days. Both of these criteria were satisfied for this test; a maximum value of 105% degradation of the sodium acetate was
achieved on day 14, and the blank DO loss was 1.36mg/l recorded on day 28. The replicate difference of extremes is also required to be less than 20% at the end of the test, the variation recorded was only 8.9%.
As the empirical formula was unavailable for the calculation of the Theoretical Oxygen Demand (ThOD), the Chemical Oxygen Demand (COD) was determined experimentally. It should be noted that the use of COD, as a reference value for degradation, is less satisfactory than the
ThOD as some chemicals are not fully oxidised in the COD test. Incomplete oxidation values will artificially increase the biodegradation value recorded.
The final conclusion of this study is that SugaNate 160NC D-Glucopyranose, oligomeric, C10-16 -alkyl glycosides, 2-hydroxy-3-sulfopropyl ethers, sodium salts is readily biodegradable under the conditions of this test.
