1. TECHNICAL HELD OF THE INVENTION
The present invention relates to self-sanitising composition that is used to form water-based sanitiser and particularly, it is an anti-nanobes, anti-microbial and anti-TVOC with long term effect. Said self-sanitising compositions consisting of titanium dioxide, silica-based binder, antimicrobial cold catalyst and distilled water. Preferably, tin oxide and ioniser compound are added to said compositions to create anti-static effect and ionizing effect respectively.
2. BACKGROUND OF THE INVENTION
Pathogens are common infectious agents such as virus, bacteria, germs, fungi and mold that may cause diseases to humans. Pathogens may be present as airborne pathogens or collected on any surfaces such as building walls, furniture, carpets etc. especially at indoor areas or confined spaces. Therefore, it is desirable to have ways to reduce the risk of exposing to these infective agents.
In the past, many approaches have been developed for disinfection or sterilization purposes. One of the methods is by using of air purifying device or air cleaning device for separating fume or dust with germs so as to purify the air. These air purifying device is typically require use of electricity and bulky in size which is not convenient to be carried from one location to another.
Meanwhile, photocatalysts are widely used for the purpose of decomposing pollutants due to its capability in absorbing light at predetermined wavelength to cause chemical reactions to take place. According to Akira Fujishima et al (2000) Titanium Dioxide Photocatalysis, Journal of Photochemistry and Photobiology, it is disclosed the Ti02 photocatalysis such as photocatalytic air purification sterilization and cancer therapy. A photoinduced superhydrophilic phenomenon involving Ti02 was also discussed.
It would hence be extremely advantageous if the above shortcoming is alleviated by having a self-sanitising composition for disinfecting surfaces that may carry infection in order to reduce pathogens and thereby prevent disease outbreak. The self-sanitising composition of the present invention is a water-based sanitiser that is directed to new technology and useful alternatives to known compositions.
3. SUMMARY OF THE INVENTION

4. BRIEF DESCRIPTION OF THE DRAWINGS
Other aspect of the present invention and their advantages will be discerned after studying the Detailed Description in conjunction with the accompanying drawings in which: FIG. 1 shows an exemplary process flow of producing the self-sanitising composition of the present invention.
5. DETAILED DESCRIPTION OF THE DRAWINGS
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by the person having ordinary skill in the art that the invention may be practised without these specific details. In other instances, well known methods, procedures and/or components have not been described in detail so as not to obscure the invention.
The invention will be more clearly understood from the following description of the embodiments thereof, given by way of example only with reference to the accompanying drawings, which are not drawn to scale.
In the present invention, compositions with sterilization effects are disclosed. Said compositions form a water-based-long-terms sanitiser and particularly, it is an anti-nanobes, anti-microbial and anti total volatile organic compounds (anti-TVOC) with long term effect.
Said self-sanitising compositions consisting of titanium dioxide, silica-based binder, antimicrobial cold catalyst and distilled water. Preferably, tin oxide and ioniser compound are added to said compositions to create anti-static effect and ionizing effect respectively.
The sanitiser of the present invention is able to perform both photocatalysis and cold catalysis. Titanium dioxide contained in the sanitiser of the present invention is a main and useful photocatalytic material so as to act as light-activated antimicrobial when irradiated with ultraviolet (UV) radiation at wavelength of 200 - 400 nm. Beyond the UV range, cold catalysis is performed by means of the antimicrobial cold catalyst contained in the sanitiser. Said antimicrobial cold catalyst may be selected from nanoparticles such as nano-silver, nano-platinum or combination thereof. Hence, a wider range of application is obtained as the light absorption wavelength is now further extended to more than 500 nm (visible range).
In general, the self-sanitising compositions as disclosed in the present invention are able to provide long term effect once it is applied to a treated area. The treated area is a surface such as but not limited to furniture, wall, clothes, skins etc. where said sanitiser can be applied on. The air surrounding the treated area becomes "AirGUARD shield" whereby negative ions in the "AirGUARD shield" will attract the airborne particles that may contain infectious pathogens and drop the particles to the treated area. Preferably, the negative ions are the "AirGUARD shield" is generated by ioniser compound or boron silicate containing compounds which contained in the sanitiser. Once the particles dropped to the treated area and in contact with the nano-silver or nano-platinum, the nano-silver or nano-platinum will penetrate the organic matters of particles and inhibit multiplication and cell growth of pathogens. It suppresses the replication, respiration and digestion system and eventually decomposes the membrane of the organic matters to achieve germicide and virucide effect. Examples of pathogen to be treated are bacteria, virus, fungi and mold. An example of virus is Middle East Respiratory Syndrome (MERS)-Coronavirus.
Meanwhile, the silica-based binder contained in the sanitiser includes but not limited to silicon dioxide with at least two different particle sizes to create the hydrophilic effect and anti-static effect. Both the particles sizes are preferably less or equal to 5nm. For example, silicon dioxide with 2 nm and 5 nm can be added to the self-sanitising composition of the present invention to enhance the bonding capability to surface so as to allow long lasting at applied surfaces. In addition, the tin oxide contained in the sanitiser will turn the treated area into an anti-static surface to minimise dust residue on surface and thereby promote air purifying and circulations.
In an exemplary of the present invention, the process of producing the self-sanitising composition is disclosed, as shown in FIG. 1. Approximately 5 to 20 % by weight of the silicon dioxide with particle size of substantially 2 nm and 5 nm is used to create the hydrophilic effect. It should be appreciated that said silicon dioxide can be of any particle size as long as it consist of at least two substances of different sizes. Said silicon dioxide acts as binder for better stability and longer lasting bonding to any applied surfaces. Approximately 3 to 5% by weight of tin oxide is then added and mixed in between the silicon oxide to create anti-static function. The mixing of the silicon dioxide and tin oxide is to be carried out for approximately 24 hours to allow for stable chemical reaction.
Upon completion of the chemical reaction, approximately 1 to 5 % by weight of antimicrobial cold catalyst such as nano-silver and distilled water with amount of 75 to 85 % by weight are added to said mixture of silicon dioxide and tin oxide. The pH level is controlled in the range of 4 to 5 before titanium dioxide is added. Approximately 1 to 8 % by weight of titanium dioxide with at least one particle size is then added into the mixture. In an embodiment of the present invention, titanium dioxide having particle size of substantially 2 nm and 1.8 nm are used. At least two particle sizes of titanium dioxide should be used in order to create uneven surface and hence enhance the hydrophilic effect and enhancing the performance of said substance. It should be appreciated that said titanium dioxide can be of any particle size as long as it consist of at least two substances of different sizes. Next, approximately 2% by weight of ioniser compound is then added to the mixture to create ionizing effect. Hence, the self-sanitising compositions are formed.
The self-sanitising composition in the present invention is a water-based solution without the need of using alcohol as solvent and thereby reducing the risk of neurotoxic. Said compositions can be applied in a spray device such as aerosol spray or any other applications that is suitable for said compositions to be applied to the surface as treated area. Besides, the pH content of the sanitiser can be adjusted depending on the type of applications. For example, if the sanitiser is to be applied on skin, the pH content would be adjusted to 5.5, while for applications on surfaces such as building walls or furniture, pH 7.0 is more favourable.
Thus, by having the sanitiser of the present invention, self-sanitising effect can be achieved effectively and this would give a favourable influence and protection to the living environments and human beings.
While the preferred embodiment of the present invention and its advantages have been disclosed in the above Detailed Description, the invention is not limited thereto but only by the scope of the appended claim.
