Surfactants

Many synthetic surfactants are not pure compounds, but consist of molecules with uniform composition and varying molecular weights. The reported molecular weight is an average value. HLB values reflect the hydrophile/lipophile nature of the molecule. Surfactants are a principle component in the preparation of emulsion polymers. They find many other uses as wetting agents, cleaning aids, and structure-directing amphiphiles for synthesis of Nanomaterials.
