Description of key information
Additional information
Several studies showed that glutaraldehyde is stable against hydrolysis under environmental conditions. However, at pH 9 a condensation of aldehyde groups was reported. A half-life of 8.2 h indicates that by exposure to the atmosphere, the substance will be rapidly degraded by photochemical processes. Photolysis study in water showed that glutaraldehyde is photolytically stable in aqueous test solutions.
The biodegradation of glutaraldehyde in domestic sludge, salt water, pond water, sediment and soil was investigated mainly under aerobic conditions except for sediments and pond water which were tested under anaerobic conditions too. The corresponding investigations demonstrated that glutaraldehyde is readily biodegradable. Furthermore, different simulation tests showed that glutaraldehyde can be regarded as biodegradable in activated sludge as well as in pond water and sediments under different oxygen conditions.
Three studies on adsorption/desorption were conducted using different soil types and sediment. All tests showed a low to moderate potential of adsorption to the different solid soils and high mobility for sediment. However, glutaraldehyde demonstrated a rapid degradation in soil by microbial activity. Therefore, a persistence of glutaraldehyde in soil is unlikely. In addition, log Koc of glutaraldehyde was calculated to be -0.83 at 25 °C. Glutaraldehyde was shown to be rapidly removed by biodegradation and irreversible binding to activated sludge. Due to the very low Henry´s law constant volatilisation is not expected. Over time, the substance will mainly distribute into water (ca. 63%) and air (ca. 37%). Based on the low log Pow bioaccumulation of glutaraldehyde is unlikely.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
