Description

SPRAY COMPOSITION WITH THYME TINCTURE AND PROTECTIVE MASK
TECHNICAL FIELD
The invention relates to a spray composition that can be applied to external surfaces with an antimicrobial effect, in particular to a medical mask.
STATE OF THE ART
Various measures are taken to reduce the contagiousness of epidemic diseases such as SARS and COVID-19 that are occurring today. The use of masks is recommended especially to prevent epidemics that can be transmitted through air or saliva. However, while the use of a mask prevents contamination with air or saliva, it cannot sufficiently reduce the contagiousness due to harmful microorganisms on the mask.
At the same time, there are many environmental, skin and mucous membrane disinfectants used in the technical field for epidemic prevention and sanitation. Incoming or outgoing airflow acts as an anti-epidemic disinfectant for pathogenic microorganisms. Except for the use of masks, the surfaces that people come into contact with must be disinfected. With the use of disinfectant, it is ensured that harmful microorganisms such as viruses and bacteria are killed on surfaces that are in contact with hands. However, since most of the disinfectants are alcohol-based, the disinfectant stays on the surface for a short time.
There are many antibacterial and antiviral drugs used in the body in the technical field, but these are basically therapeutic drugs. Due to the increase in drug use, bacteria and viruses resistant to antibiotics are emerging. Due to the decrease in the effect rate of drugs, it is necessary to develop measures to prevent the transmission of epidemic diseases.
Masks with antiseptic properties, especially with the use of thyme, and antimicrobial properties are known in the art. RU2016106948A discloses the production and method of application of medical masks with antimicrobial and antibacterial action, including mycobacterial tuberculosis. The recommended medical mask is antibacterial, has antimicrobial and antibacterial action, including those related to mycobacterial tuberculosis, and is used in general medical practice for individual protection of the respiratory organs from infections transmitted by airborne droplets. It is especially effective in lung diseases, tuberculosis dispensaries, and in cases where the risk of tuberculosis is high. The medical antibacterial mask is a three-layer spunbond medical mask, ultrasound-treated,: 20 ml of hydrogen peroxide, 200 ml of 6% food vinegar; A solution containing 2 ml of colloidal silver, 6 ml of 100% natural essential oil mixture (2 ml of essential tea tree oil, 2 ml of essential thyme oil, 2 ml of essential eucalyptus oil), hawthorn and water components diluted in alcohol tincture in a ratio of one to five, drying and packed in separate packages by vacuum drying. The method of manufacturing the medical mask differs from the previously known in that it involves ultrasound treatment of a multilayer cavity for a medical mask of antibacterial nonwoven material with a solution containing hydrogen peroxide, food vinegar, colloidal silver, a 100% mixture. Natural essential oils (tea tree essential oil, thyme essential oil, eucalyptus essential oil) diluted with alcohol tincture of hawthorn, further pressing, vacuum drying and individual packaging are applied, which guarantees defense against the penetration of water, oxygen and light. The method of applying a medical antibacterial mask, accordingly personal protection, provides individual protection from airborne infections, including mycobacterial tuberculosis of the respiratory tract.
DESCRIPTION OF THE INVENTION
The object of the invention is to produce an antimicrobial spray composition that can be applied to surfaces to reduce the contagion rate.
To achieve said object, the invention relates to a spray composition comprising an essential oil with a tincture of thyme obtained by treating the thyme (thymus) plant with alcohol. The spray composition also contains natural resin added to the essential oil as a binder to the surface. The natural resin, by applying the spray composition to a surface, for example a protective surgical mask, is fixed for a certain time by adhesion to the fiber structures that make up the mask, allowing the effect of the antimicrobial, especially antiviral carvacrol, which is effective against the corona virus, in the thyme tincture for at least 4 hours. Moreover, when the antiviral effect is over, it is possible to reapply the essential oil because it does not leave a residue that inhibits the barrier function of the mask. Thanks to the thyme tincture in the spray composition, harmful microorganisms that can be transmitted by air or saliva are inactivated. On the surface where the spray composition is applied, harmful microorganisms that can be transmitted by air or saliva are trapped in the thyme tincture. The microorganisms trapped in the thyme tincture are destroyed by disintegration during the drying of the thyme tincture. Thus, any viruses, bacteria or other harmful microorganisms cannot be accommodated on the applied surface. Thanks to the spray composition, a chemical barrier is created against harmful microorganisms that can be transmitted through the air or saliva. With the chemical barrier, the possibility of epidemic diseases such as Sars and Covid-19 being found on any surface is reduced and the contagion rate of the epidemic is reduced. Thyme species (Thymus) used in the preparation of thyme tincture can be obtained from a group selected from among the species known as black thyme and Izmir Thyme. As natural resin, sweetgum tree resin, pine tar or terebinth tree resin or a mixture of these can be used.
In a preferred embodiment of the invention, the spray composition also contains boric acid.
In a preferred embodiment, the weight ratio of boric acid is between 0.005% and 0.015%. Thanks to the use of boric acid, the antiviral, antibacterial effect and protective effect against bio-agents provided by the composition are strengthened.
In a preferred embodiment of the invention, the weight ratio of essential oil is between 1% and 8%. In this way, the essential oil ensures that the active ingredients in thyme act on the application surface for a certain period of time. The stated weight ratio was specifically chosen for the longest lasting antiviral efficacy on a fiber respirator.
In a preferred embodiment of the invention, the weight ratio of essential oil is chosen as 5.5%. The use of essential oil at a weight ratio of 5.5% is the weight ratio with the highest antimicrobial properties. The most optimal value in terms of cost and antimicrobial effect is 5.5% by weight, since the essential oil used more does not make any contribution.
In a preferred embodiment of the invention, the essential oil contains carvacrol in the range of 70% to 80% by weight. Carvacrol is a phenol compound contained in essential oil, and it strengthens the chemical barrier provided by thyme tincture, due to the antiseptic properties of phenol compounds against viruses and bacteria. In an alternative embodiment, instead of carvacrol, the thymol compound in thyme oil can be used within the specified range. In a preferred embodiment, the composition comprises 0.1-2% by weight of natural resin, particularly 1%. The ratios chosen are sufficient for the spray composition to adhere, for example, to the surgical mask from its outer wall.
In a preferred embodiment of the invention, the total weight ratio of the thyme tincture in the spray composition is between 0.5% and 10%. Thanks to the selected weight ratio of the thyme tincture, the spray does not create a heavy odor on the surface where the composition acts and it is ensured that it is at a level that will not be disturbing by the user during inhalation. A preferred embodiment of the invention is a protective mask comprising a spray composition as described above. When the spray composition is applied to an inner surface of the mask, a chemical barrier is created in addition to the mechanical barrier provided by the mask. Thanks to the chemical barrier created in the masks, the contagious disease rate that can be transmitted by air is reduced. If harmful microorganisms that can be suspended in the air or can be transmitted through saliva pass into the mask, they are trapped in the spray composition and are prevented from reaching the mask user. Thus, contagious diseases that can be transmitted through air or saliva are prevented from being transmitted to the user wearing a mask with a spray composition.

DETAILED DESCRIPTION OF THE INVENTION
In this detailed explanation, the subject development of the invention is explained without any limitation and only with reference to examples to better explain the subject.
Figure 1 shows the application of the inventive spray composition on the mask. A spray composition (30) containing thyme tincture stored in a spray can (20) is applied to an application surface (12) of a protective mask (10). It adheres to the application surface (12) of the sprayed composition (30). The application surface can be the outer wall of the mask, or alternatively, it is possible to apply a spray composition to the inner wall. The mask (10) creates an extra chemical barrier to prevent harmful microorganisms circulating as pathogens in the air by applying the spray composition (30) to the application surface (12). The harmful microorganisms that can adhere to the application surface (12) of the mask (10) are captured by the spray composition (30) located on the application surface (12) and are destroyed by disintegration during the drying process from the time the spray composition (30) is applied. Thus, harmful microorganisms that can be transmitted through air or saliva are prevented from reaching the face of the user wearing the mask (10). The spray composition (30) maintains its chemical barrier property on the application surface (12) of the mask (10) for an average of 4 hours. The spray composition (30) binds to viruses, bacteria and other microorganisms and neutralizes them thanks to the chemical compounds in it. Inactivation of disease-causing molecules by using its antimicrobial feature is provided by a thyme (thyme) tincture included in the spray composition (30). Thyme tincture ensures that the damage trapped during the drying process on the application surface (12) on which it is applied as a liquid is neutralized by the disintegration of microorganisms. In order to strengthen the effect of thyme tincture, thyme is treated with alcohol using the extraction method and its antimicrobial effect is strengthened. In addition, essential oil is added to strengthen the effect of thyme tincture. Obtaining the required amount for adding essential oils into the thyme tincture is provided by the traditional retort method. In addition to the addition of alcohol and essential oil, boric acid is added to strengthen the antimicrobial effect. Due to the volatile effect of alcohol, natural resin is also added to the thyme tincture in order to increase the fixation of the active ingredients on the applied surface.
Thyme tincture is produced using thyme, so it has an antimicrobial effect. With the antiseptic effect of the phenol compounds in thyme, bacteria and viruses are inactivated. The essential oil (essence) obtained by distilling the dried leaves, flowers and buds of thyme with water vapor at a rate of 2% to 8% is rich in monoterpenic phenols such as Carvacrol and has very strong microorganism-killing properties.
Carvacrol (C6H3(CH3)(OH) C3H7) in the essential oil is one of the active ingredients and has antiviral, antiseptic and antibacterial properties. Carvacrol has antimicrobial activity against 25 different periodontopathic bacteria and strains. Carvacrol is in the range of 70% to 80% by weight in essential oil.
Boric acid (H3BO3), which is included in the thyme tincture to strengthen the antimicrobial effect, is a weak acid of boron. Boric acid is obtained by the reaction of colemanite ore with sulfuric acid or borax with a mineral acid. Boric acid and gypsum (CaSO4.2H2O) are formed as a result of the reaction of colemanite (Ca2B6O11 .5H2O) in sulfuric acid (H2SO4) solution. Gypsum crystals are precipitated, and boric acid is produced by crystallization. Since boric acid has antibacterial properties, it acts as a protective layer in the thyme tincture. Boric acid also has antibacterial properties that will not harm the surface when applied to living surfaces. A weight ratio of 0.01% is added to the thyme tincture.
Thyme tincture has a volatile feature thanks to the alcohol it contains. Natural resin is added to the thyme tincture in order to reduce the volatile property and increase the chemical protection time on the surface. Thanks to the fast solidification of the natural resin on the applied surface, during contact with the adhesive and air, the contact of the active substances with the applied surface is facilitated and the residence time of the active substances on the applied surface is increased.
It would be very helpful if we included weight ratios for a few examples of the spray composition here in a table. Example 1
