The present disclosure is directed to synthetic textiles treated with h-PEI derivatives, such derivatives possessing the general structure shown below: (R)x-h-PEI-(A)y where R is a non-hyperbranched hydrocarbon group, said hydrocarbon group having at least one linear portion, said linear portion having between 5 and 30 carbon atoms; where x is a number from 1 to 10,000; where h-PEI is a hyperbranched polyethyleneimine; where A is an organic compound having from 1 to 4 carbon atoms; where y is a number from 0 to 500; and wherein R is present in an amount of between about 0.1% and about 80% by weight of the h-PEI derivative. The chemical treatment imparts durable odor control, softness, wrinkle resistance, and moisture wicking to substrates treated therewith.
