Anionic surfactants, typically lignin sulphonates produced as a by-product of the Kraft paper making process, are used extensively. These large surfactant molecules, which are several orders of magnitude larger than any disperse dye molecule, adhere to and encapsulate the large dye pigment particle and form a stable dispersion.
If I omit "several orders of magnitude", and say "which are larger than .........", this sentence makes sense to me. But due to presence of "several orders of magnitude" makes this sentence awkward to me.
Please, help me to clarify this problem.
