Britens LAS is a strong anionic surfactant. In cleaning formulations, it are the surfactants which do the actual cleaning job. Its equivalent acid, LABSA (Linear Alkyl Benzene Sulphonic Acid) is one of the most used anionics worldwide. As an acid, it is liquid and has harmful disadvantages in handling and usage. In the actual cleaning formulation, the acidic LABSA is usually neutralised to its sodium salt LAS. Sirius offers this salt as Britens LAS; ready to blend.

Britens LAS powder is hygroscopic by nature. Britens LAS granulate is engineered in such a granular form that water absorption is limited to a minimum. Due to the cyclical benzene-groups in the molecule, Britens LAS is readily biodegradable according to OECD30-1A. Another readily biodegradable anionic is our Britens AOS. Readily biodegradable non-ionics are our Britens APG series.
