Description

The present invention relates to household chemicals and is intended to eliminate unpleasant odors in residential and public buildings.

Known methods for aromatizing rooms by burning aromatic resins, various herbs and aromatic trunks and branches of woody plants, as well as various versions of this method based on the impregnation of paper, fabric, wood, substrate with aromatic substances.

The method has serious disadvantages associated with the formation of coal during burning, and therefore the possibility of fires and burn injuries. In addition, during combustion, the pyrolysis of individual components takes place, and redox reactions take place with the formation of toxic and even carcinogenic substances (Carbon monoxide - CO, benzpyrene and

DR.).

It is known to use mixtures of essential oils as a perfume in deodorants. However, they have a complex composition, and their use as freon propellants significantly affects the ecological situation. The use of compressed air for the spray of essential oils and individual WDFs is practically impossible due to the fact that when sprayed, fine particles of oil, having a large surface, are oxidized by atmospheric oxygen and lose their native aroma, in addition, long-term storage of essential oils in air is not possible for the same reason. Thus, various methods, in addition to burning natural fragrant components, require the use of containers (aerosol cans, atomizers, combustible solid carriers, etc.). The storage of these products is associated with such disadvantages as fire and explosion hazard, disturbance in the process of storage of the smell, chemical circumstances, and the inability to reuse expensive containers. The most intrinsically closest method is the aromatization method by applying the aromatic substance to a substrate, for example onto a dense fabric and subsequent natural evaporation of the aromatic substances. However, the surface is constantly open and fairly developed.

evaporation creates favorable conditions for the oxidation of aromatic substances; the rate of natural evaporation of high boiling liquids is very low,

The aim of the invention is to increase the efficiency and quality of aromatization of air.

This goal is achieved by the fact that aromatic substances, for example, essential oils, are added in a metered amount to ethereal waxes, which are then formed into tablets, a. In order to aromatize the tablets, they are placed in a vessel with heated water, as a result of which the wax melts, and aromatic substances are released with water vapor from its thin film on the surface and their convective diffusion into air occurs. In this case, the essential oil aocsc is a mobile substrate that changes in texture from temperature.

The method is carried out as follows.

8, aromatic wax is added odoriferous substances, for example, metered-dose essential oils, tablets are formed from it, which are then placed in a vessel with heated water, as a result of which the wax melts, releasing aromatic substances into the air, additionally moistening it with evaporation of water from a vessel into the environment. Hot water promotes thermal convection and accelerates the diffusion process of the spread of flavors in the air,

Taking into account the significant retention capacity of the wax in relation to volatile substances in the solid state, the wax substrate can be used for a long time, and the wax, after removing aromatic substances from it, can be saturated again and be used in this process constantly.

In addition, waxes have fixing properties, which contributes to the long-term and selective evaporation of aromatic substances, giving the aroma a nativity.

Example 1 In an open vessel with an evaporation surface of 0.15 m2 cold water was poured in an amount of 0.5 L and 1.2 g of lavender essential oil was placed. The water was heated to 70 ° C and its temperature was kept within. The time of evaporation and diffusion of bulk oil from the surface was recorded. As a result, it was found that after 1.5 hours the heavy and partially oxidized oil fraction remained poorly evaporated at this temperature in water;

the amount of 0.23 g, which practically did not give the initial aroma of lavender, but rather worsened the main smell with resinous notes.

In parallel, the same amount of ether masp was applied onto a fabric substrate (felt) with an evaporation surface of 0.15 m2. At a temperature of 25-30 ° С, evaporation and diffusion of the main aromatic components took place from the substrate for 2.5 hours, and heavy fractions with resinous notes remained on the substrate.

Example 2: An open vessel with an evaporation surface of 0.15 m was poured into a cold aode in an amount of O, B l, and 4 g of wax was placed, which was saturated with 1.2 g of lavender essential oil. The water was heated to 90 ° C and the temperature was maintained within the range of 90-95 ° C. The time of evaporation and diffusion of the main volatile part of the essential oil was 3.2 hours to contain a heavy fraction of oil in the amount of 0.23 g in the wax.

As follows from the presented examples, the proposed method allows to extend the effective period of the main flavor by more than 2 times. At the same time, there is no sharp evaporation of the components of the essential oil, which does not saturate the surrounding air with an excessive aroma - l conveys the smell inactive smell of fresh plants.

The table shows the ratios of substances and flavorings. Moreover, some waxes obtained by processing the corresponding extracts can be used for several flavorings.

To simulate plant odors, not only natural essential oils can be used, but also synthetic aromatic substances, for example, ionon - with the smell of night violet, lmnalool - with the smell of lily of the valley, citral - with the smell of citrus, as well as other substances with a floral, fruity or fantasy direction mi odors, in quantities corresponding to natural essential oils.

It should also be noted that rose wax can be used as a universal odor carrier for all types of fragrances, as it is most in harmony with all directions of smells.

The present invention can be used not only as a means for aromatizing rooms, but also for medical and cosmetic purposes - inhalation, masks, applications.

An advantage of this method is the fact that the wax for removing aromatic substances from it can be used repeatedly, and the packaging of wax substrates can be carried out in foil or polyethylene film, which does not require original equipment for the production of special containers that cannot be disposed of after use.

In addition, wax substrates in the form of a strong holding power of the wax have a prolonged action and significantly save expensive fragrances.
