We study the influence of the modified chemical composition resulting from the rotational mixing on the wind parameters. particularly the wind mass-loss rates. We use our non-local thermodynamic equilibrium wind code to predict the wind structure and compare, the calculated wind mass loss rate for the case of scaled solar chemical composition and the composition affected by the CNO cycle. We show that for a higher mass traction of heavier elements Z/Z(circle dot) greater than or similar to 0.1 the change of chemical composition from the scaled solar to the CNO-processed scaled solar composition does not significantly affect the wind mass loss rates.
