Early methods of making nail polish used a variety of methods that today look charming amateurish.One common technique was to mix clean scraps of movie film and other cellulose with alcohol and castor oil and leave the mixture to soak overnight in a container.The mixture is then stained and colored and perfumed.Though recognizable as nail polish,the product was far from what we have available today.The modern manufacturing process is very sophisticated operation utilizing highly skilled workers,adavanced machinery,and even robotics.Today's consumers expect nail polish to apply smoothly,evenly and easily;to set relatively quickly;and to be resistant to chipping and peeling.In addition,the polish should be innocous.
