The specialists of KorolevFarm LLC have developed technologies for the production of nanocosmetics using a hydrocavitation colloid rotary mill by cold emulsification. The special design of the plant ensures the production of nanoemulsion in one pass of the raw material through the mixing unit. The flow dosing system ensures the production of nanoemulsions by mixing cold - temperature 5 o C - 10 oС, and hot phases is the melting point of the structure-forming components. This allows not only to reduce energy costs for heating, but also to exclude thermal effects on biologically active components in the nanoemulsion. Heating is carried out only in the fat phase, which includes solid fractions of structure-forming components, since it is necessary to achieve the required fluidity for its injection through pipes into the mixing unit.

Practically no time is required for cooling, since when the cold and hot phases are mixed, the resulting nanoemulsion has a temperature significantly lower than with the classical method of producing emulsions.

In a conventional cosmetic emulsion for stability, i. E. to prevent droplets from merging into conglomerates during the emulsification process, emulsifiers are used in the product formulation. In the production of an emulsion in the classical way, the diameter of fat droplets or spheres is very significant, the interfacial tension that prevents the coalescence of emulsion particles can only be provided by a system of emulsifiers, and this is a large percentage of the introduction of emulsifiers and surfactants. To improve the consumer properties of a cosmetic product, it is necessary to minimize the size of the microsphere droplets, since the smaller the size of the microsphere, the more stable it is, which means it contributes to the stability of the product and its aesthetic appearance. However, classical homogenizers do not allow reaching sizes less than 100nm, which is nano-size.

Applying technologies for the production of nanocosmetics using a hydrocavitation colloid mill of a rotary type, a nano-size of the emulsion is provided. Due to the nanosize, nanocosmetics require significantly fewer structure-forming ingredients that stabilize the products, and this significantly reduces the cost of the nanoemulsion. In conventional emulsions, due to gravity, the difference in the density of droplets and the medium in which they are located can lead to phase separation. If the density of the droplets is less than the density of the medium, then they will rise to the surface. This separation cannot be completely eliminated, but it can be reduced by reducing the droplet size. Thus, particle size reduction - creating nanospheres, inhibits unwanted delamination and prolongs the product life cycle.

Moreover, nanoemulsion has the best biological compatibility with human skin. In nanocosmetics, the amount of structure-forming agents, which are often allergens and have a negative effect on the skin, is significantly reduced.

The creation of a nanoemulsion also affects other parameters of a cosmetic product, such as viscosity, color and odor intensity, and product texture.

The rotary hydrocavitation colloidal installation provides the production of nanoemulsions with nanospheres in the range from 40 to 100 nm. RGKKU creates local overpressure on fat globules - emulsion nanospheres - in tens of thousands of atmospheres. The rotary cavitation principle is based on the use of overpressure resulting from the cavitation effect. The effect of cavitation is accompanied by microexplosions, ultrasound, as well as mechanical cuts and impacts when exposed to hundreds of cutting pairs.

The effect of cavitation can be defined as a microvacuum explosion with rupture of the shell of fatty macrospheres in the entire volume of the chamber and the formation of nanospheres. Microvacuum explosion is the formation of areas with ultra-high and ultra-low pressures.

Nanospheres of the dispersed phase of nanocosmetics obtained on a rotary hydrocavitation colloidal installation are an order of magnitude smaller than particles in emulsions obtained by the classical method. Nanospheres have a more uniform size distribution. The average size of nanospheres of the oil phase of the nanoemulsion obtained on a rotary hydrocavitation colloidal installation is in the range from 40 to 100 nm.

The emulsions obtained on a classical homogenizer have an average size of about one or more micrometers.
Two-phase method for the production of nanoemulsions. The processes of mixing and production of nanoemulsions take place under short-term temperature exposure up to 42 0 С, with traditional structure-forming components. This allows you to maintain the activity of all active substances. Unlike traditional methods, in which emulsification occurs at 85 0 С - 95 0 С. protein structures begin to degrade at temperatures above 45 ° C).
Application of nanotechnology. The process of creating a nanoemulsion confirmed the average size of nanospheres in an emulsion is 40 - 80 nm (0.04 - 0.08 μm) and does not exceed 100 nm (0.1 μm)
Production of nanocosmetics with unique sensory properties
Reduced energy consumption. In the production of emulsions, the main energy consumption occurs when heating only the wax fraction, which is 150 - 200 kg (l) per 1000 kg (l), (30-40% of the total volume).
Ensuring hypoallergenicity, bioavailability and biocompatibility by significantly reducing the level of surfactants, emulsifiers and preservatives that can have a negative effect on human skin.
