Description of key information

Additional information

Manufactured fresh substance may contain 40 -50% water. In drying it stabilises and may harden through adsorbing CO2from the atmosphere (carbonisation). Solubility in water is generally low in alkaline water and increases as pH gets lower. In long term, GLS will slowly dissolve in water in the environment. GLS and its dissolved constituents partitions predominantly in the aquatic phase. Volatilisation from water to atmosphere of these inorganic (ionic) constituents is very low. Adsorption to soil and sediments is ion specific. The known main constituents have low or negligible potential for bioaccumulation. GLS contains trace level (< 0.1%) metallic and variable amounts of organic constituents, which may have slightly higher accumulation potential.
