ROSULfan®D911 (Sodium salt of alcohol C9-C11)

ROSULfan D911 is an anionic surfactant from the group of alkyl sulphates with a carbon chain length of C9-C11. The product is an alkyl sulfate sodium salt and is available as a 35-37% aqueous solution of low viscosity and colour from colourless to light yellow. This product shows very good foaming properties, creating high and time-stable foams, even in hard water.

Foams obtained from ROSULfan D911 are characterized by a high degree of hydration (so-called wet foam) and a small diameter of bubbles (fine foam). ROSULfan D911 also has a low tendency to gel in electrolyte solutions, which eliminates problems related to the local increase in viscosity (e.g. in dosing systems).Due to its unique foaming properties, the product is primarily used as an air-entraining agent in the construction industry, mainly in the production of drywall. Thanks to its use, it is possible to manufacture light and durable materials. ROSULfan D911 is also used as a component of synthetic extinguishing media, where it is the basic foaming agent and can be mixed with other surfactants offered by the company. The product can be used in alkaline extinguishing media with a tolerance to caustic solution up to 90 g/l.ROSULfan D911 is also used as a component of drilling fluids in tunnelling processes, where its foaming and wetting properties play an important role as well.Product meets biodegradability criteria in accordance with OECD methodology (biodegradability data based on literature data).
