Choline Chloride 75 Liquid
Choline Chloride is a minimum 75% active solution of 2-hydroxy-N,N,N-trimethylethanaminium chloride. Choline Chloride is completely water soluble and is used to control swelling of water sensitive clays. It has a small hydration radius and can easily substitute sodium ions found in the crystal structure of native clays thereby effectively blocking the site for water hydration.
Typical loadings are in the range 2.0 to 4.0 L/m³. Choline Chloride is non-toxic, readily biodegradable, non-foaming and non-oil wetting.
Mixing & Handling
The product is corrosive and requires special handling procedures. Refer to Material Safety Data Sheet for handling instructions.
