Is it safe to use after shave creams that contain triethanolamine?

Yes, but...: commonly used attitude to many cosmetics triethanolamine is safe if it's not used for prolonged periods. That is after shaving rinse your face off thoroughly. Prolonged use IE day after day may be a concern but that's not been proven. It should not be difficult to find shaving cream that does not contain this product, at the very least make sure the concentration is no higher than 5%.
