• Nail polishes are normally packaged in small bottles, more commonly known as “containers", with a capacity of about three to twenty-five milliliters, or even a few centilitres. They are applied with the help of a small brush, most often integrated within a cap sealing the bottle. Only a few minutes after its application, the substance of the nail polish hardens and then forms a coating on the nail, resistant to water and peeling, can last several days.
• Nail polishes are designed especially to beautify the nails, but also to protect them.
• nail polish does not escape this rule: there is no single formulation for nail polish.
• nail polish like any cosmetic product, must meet a number of regulations and legislation relatively strict because of their application in contact with the human body.
• certain types of ingredients are generally used in the composition of nail polish, such as:
• one or more agents and / or film-forming resins that is to say, synthetic polymers or semisynthetic, such as nitrocellulose, for example, for producing a continuous film on the nail;
• Nail polishes are sometimes called suspension, that is to say a liquid product containing particles, in the case of nail polish pigments in a base, said base comprising one or more film-forming agents, one or more agents plasticizers and one or more solvents, divided and mixed to form a homogeneous, durable and stable product for a period of two to three years.
• nail polish has become an important fashionable asset and, consequently, one of the most important elements of consumption, used by many women in particular. Each shade corresponds to a season.
• women today like the opportunity to change polish whenever they want. Moreover, they often have a large collection of nail polish in their possession. Nevertheless, the desires or demands of women are sometimes difficult to satisfy. Indeed, although there are huge color palettes, some women are sometimes looking for a nail polish of a particular color, for example, to coordinate with a garment or simply meet a criterion of fashion. In some cases, such nail polish is not commercially available.
• nail polish is widely produced, produced and packaged on a large scale by means of various devices on production and packaging lines, such as:

Firstly, said system is dedicated to a specific type of formulated products and is not transferable to any product category, since the paints are generally manufactured for volumes of the order of one liter, whereas the Nail polish is contained in vials at most a few tens of milliliters. In addition, the exemption of pigments or dyes in the form of powder results in a less precise dosage, or even approximate in some cases, and consequently some difficulties in obtaining the desired shades.
