Extreme attention to quality control is essential throughout the manufacturing process.Not only does quality control increase safety in the process,but it is the only way the manufacturercan be assured of the consumer confidence and loyalty.A single quality of polish can lose a consumer forever.Regardless of quality control,no single polish is perfect;the polish always represent a chemical compromise between what is desired and what the manufacturer is able to produce.
Teh nail polished is tested throughout the maufacturing process for several improtant factors=drying time,smoothness of flow,gloss,hardness,abrasion resistance,etc.Subjective testing,where the mixture or final product is examined or applied is on going.Objective,lab testing of samples,though more time consuming,is also necessary to ensure a usable product.Laboratory tests are both complicated and unforgiving,but no manufacturer would do it without them.
