A biodegradability of the test substance of 97.38% in 28 days at 20 mg/l with respect of the 10 day window (Modified Sturm test).

In the conditions of the test, based on the behaviour of four representative compounds of the test UVCB test substance (C16 alcohol, C18 alcohol, C16 monoglucoside and C16 diglucoside), it can be concluded that Acetalization product between glucose and C16/18 (even numbered) - alcohol was strongly adsorbed, saturating the soil from 0.5 hour of exposure. The Log Koc range of the Acetalization product between glucose and C16/18 (even numbered) – alcohol is 4.71 to 5.57 depending on the soil. According to the results obtained for adsorption/desorption isotherms of Acetalization product between glucose and C16/18 (even numbered) – alcohol, desorption was lower than adsorption in all the test soils indicating easy and strong adsorption and low desorption.
