Bio-Soft® N Series

High Active Nonionic Surfactants from Stepan.

Bio-Soft® N-Series: Linear Alcohol Ethoxylates

The Bio-Soft® N-Series from Stepan provides excellent wetting, emulsification and detergency with moderate foam production.

Stepan’s Bio-Soft line of linear alcohol ethoxylates are biodegradable, mild to the skin and easily colored and fragranced. Stepan’s LAEs range from clear liquids to semi-solids with relatively low melting points.

The Bio-Soft LAEs are named according to the alcohol chain length and the average number of moles of ethoxylation.

For instance, Bio-Soft N1-5 has a carbon chain length of 11 and 5 moles of ethylene oxide. Bio-Soft 23-3 has a carbon chain length of 12-13 and 3 moles of ethylene oxide.

These surfactants are used in numerous household, institutional and industrial cleaning and process formulations.
