Abstract
Residual lipophilic reactants and by-products of surfactant manufacture (e.g. fatty alcohols, ethers, esters, etc.) may be adsorbed from surfactant compositions with a solid hydrophobic sorbent having pore sizes sufficiently small enough to effectively preclude molecular adsorption of the surfactant molecules therein. Surfactant compositions containing long-chain alkyl glucoside mixtures, as the major active surfactant component, may be refined to a form substantially free from lipophilic impurities by dispersing the surfactant composition into a suitable liquid carrier system and adsorbing the contaminants from the composition with the sorbent.
