The term viscosity refers to resistance to fluidity, viscosity or viscosity. In more technical terms, viscosity refers to the resistance of any fluid to deterioration under surface tension. Liquids with high viscosity are defined as dense and viscous. Liquids that show no resistance to surface tension are called ideal fluids. In general, all liquids exhibit more or less resistance to surface tension. However, a higher viscosity indicates that the fluid is thick-flowing and a lower viscosity indicates that the fluid is fine-flowing.

The fruit juice of the mistletoe (viscum) plant is typically thick-flowing and comes from the expression viscosity. Mistletoe is used in the production of mistletoe and viscous means thick as mistletoe.

According to the laws of physics, the layers of any liquid move at different speeds at the time of flow. The density of the liquid flow results from the surface tensions between the layers of the liquid which resist the force exerted by the surface.

Creams, lotions and similar cosmetic products have become a part of life today. These products are generally desired to be more fluid rather than dark. People often think that more fluid products are safer for the skin. Scientists are studying the flow and deformation properties of materials, their flexibility and viscosity. The color, content, density, hardness and molecular weight of cosmetic products are very important in this sense. Each cosmetic product must have a viscosity appropriate to the structure and manner of use. If a toothpaste does not become fluid, it drops piece by piece from the tube when squeezed.

Cosmetic products are not offered to consumers until they have undergone precise testing and testing. The viscosity of the products in the manufacturing companies is determined using measuring devices. These devices measure the viscosity of perfumery and cosmetic products quickly and reliably.

However, viscosity determination analyzes are carried out by accredited laboratories on physical and chemical analyzes. The legal regulations issued in these studies or the standards published by domestic and foreign organizations are complied with.
