Additional information

C12/14 alkyl polyethoxy glycidylether is readily biodegradable and has a moderately low log Kow of 3.5 which was determined from the ratio of the solubility in water and octanol.

C12/14 alkyl polyethoxy glycidylether will sorb based on its hydrophobicity as it has similar to alcohol ethoxylates no specific functional groups which will lead to additional sorption. Based on the measured log Kow of 3.5 only minor sorption to soil and sediment is anticipated (see mobility according to McCall). Because of the expected correlation between log Kow and Koc the Koc can be calculated using standard equations. KOCWIN calculates a Koc of 315.3 L/kg which equals a Kd of 6.3 L/kg for a soil with 2% organic carbon.

Mobility according to McCall et al. (1980): KOC 0 – 50 very high, KOC 50 – 150 high, KOC 150 – 500

medium, KOC 500 – 2000 low, KOC 2000 – 5000 slight, KOC > 5000 immobile.
