Modern nail polish is composed of three principal ingredients : resins, solvents and pigments. Correct proportions and blending produce polish that is easy to apply, gives good coverage and adheres firmly to the nail. It should also be sufficiently porous to enable the nail to breathe, even when several coats are applied. Only the finest ingredients go into MAVALA Mini Color. Quality nail polish, properly applied over a protective base coat, MAVALA 002 or BARRIER-BASE, should last five to seven days, given normal wear and tear. A layer of COLORFIX or MAVADRY applied at the time of a manicure, and every second day thereafter, will make polish last a maximum length of time. Nail polish that is too thick is difficult to apply, does not dry properly and tends to peel. It can be restored to its proper consistency with the addition of a Thinner specially formulated for this purpose, added very sparingly and allow to set before using. Never add nail polish remover or acetone, as these solvents contain water and will cause the polish to separate. Nail polish tends to thicken with time, particularly if the bottle is not closed tightly between applications. Avoid leaving the bottle open for more than a few minutes; keep tightly closed and in a vertical position when not in use. Nail polish becomes thicker when cold, thinner when warm. However never heat or expose it to high temperatures. One-coat, quick-drying nail polishes are useful for the woman who does not have time for a manicure or whose nails need a quick touch-up. They are usually less brilliant and less resistant to peeling and chipping than normal polish.
