    NATURAL COMPOSITION AND METHOD FOR PREVENTING ALGAL
    GROWTH ON OUTDOOR SURFACES
    BACKGROUND OF THE INVENTION
    Generally, outdoor rugged surfaces are exposed to the effects of sunlight and moisture resulting in algal growth. The outdoor surfaces such as ceramic tiles, concrete, brick, natural stone and pavement stone surfaces are frequently colonized with algal growth, tile plague and other unwanted growth such as dirt, moss, green pads and the like. Outdoor rugged surfaces especially under damp or wet conditions are more susceptible to algae and moss or fungal growth. Outdoor floor and tile surfaces often comprises smaller or larger cracks and crevices, where algae or other unwanted moss growth can have access to fertile soil and grow larger. Once the cracks are filled with algal growth, the algal population becomes larger, especially on top of the paving stones.
    Conventional methods of controlling algal growth on outdoor rugged surfaces comprise the use of mechanical and chemical methods or a combination of both methods.
    Mechanical methods include sand blasting, grinding, steam cleaning, brushing, scouring and use of blowtorches on the surfaces. In most cases, these procedures are cumbersome, labor intensive and rather expensive, and do not always give a desirable outcome.
    DE1571593 Al (KOVACHY, J.M.) discloses a composition for cleaning and treating stone surfaces, the composition comprising, e.g. 10-44 wt% ammonium bifluoride and 1020 wt% phosphoric acid, up to 6 wt% of a surface-active agent, and 10-30 wt% corns syrup and water. The compositions may comprise commercial thickeners to increase the
    DK 2017 00142 A1 viscosity of the composition and surfactants. This composition produces a thin film on the surface of the stone, making it dirt- repellent and contaminant-repellent.
    Predominantly in every algaecide, dosages of 50 ppm of hydrogen peroxide was used. In horticulture and agricultural areas or surfaces, this dosage was too phytotoxic for nearby useful young plants, although older plants survived in this dose rale. The hydrogen peroxide is a biocide, rather than an algaecide, there is always a risk of .root damage,
    Therefore, careful and selective dosage of hydrogen peroxide could he used on older, more resistant plants.
    Further, the known and existing composition does not use any naturally available extracts such as grapefruit seeds against algae growth, or disinfection of hard surfaces. Further, the existing composition is unable to inhibit photosynthesis process of a microbe such as algae completely, where these microbes will reproduce and grow again over a period. However, the usage of chemical compositions for cleaning and treating dirt, contaminant, or microbial infected surface are avoided to support the eco-friendly environment.
    Chemical methods include coating the surface using oxidizing agents, halogens, special chemicals, solvents, detergents, enzymes or other chemical compounds. However, the coating wears away over time and are not completely weather resistant. Hence, there still exists a need for a natural composition such as a grapefruit seed composition, and method for preventing algal growth on outdoor surfaces such as ceramic tiles, stone, brick and concrete surfaces.

    DK 2017 00142 A1
    The grapefruit seed extract can be prepared using methods known in the art. According to one embodiment, one of the methods for preparing the grapefruit seed extract comprises the following steps, 1. boiling 250 grams of crushed grapefruit seeds in 5 liters of water for 5 minutes to form a solution; 2. cooling the solution to about 40 degrees Celsius; and
    3. filtering the solution to obtain the grapefruit seed extract.
    Algae colonization, green pads and moss growth generally occur on outer surfaces of ceramic tiles, bricks, concrete and paving stones. These rugged outdoor surfaces may comprise numerous cracks and crevices in which the algal growth flourishes which ultimately leads to slippery surface and results in damage to the structures. FIG. 1 illustrates algal growth 104 in crevices and/or cracks 102 in an untreated outdoor surface
    110. The composition of the present invention can be used to treat the surfaces in order to prevent algal growth, tile plague and moss growth. The composition forms a chemical connection with the silicates present in the coating of the surfaces 110 resulting in a solid layer 106, which fills the cracks and/or crevices 102 thus preventing algae's access to soil.
    The solid layer 106 formed over the surface 110 by treatment with the present composition thus prevents algal growth and colonization. FIG. 2 illustrates a solid layer sealing the crevices and cracks in an outdoor surface treated with the composition for preventing algal growth.
    In another embodiment, the grapefruit seed based composition for preventing algal growth on outdoor surfaces, comprises ammonium hydrogen-fluoride in a concentration of preferably about 5 volume percent; phosphoric acid in a concentration preferably of about volume percent; sodium dodecyl benzene sulfonate in a concentration preferably of about 0.5 volume percent; 94 volume percent ethanol in a concentration preferably of about 2.5 volume percent; crushed grapefruit seed extract in a concentration preferably of
    DK 2017 00142 A1 about 5 volume percent; anionic surfactant in a concentration preferably of about 2 volume percent; and water in a concentration of about 80 volume percent.
    In an alternative embodiment, the present invention relates to a method 200 of preventing algal growth on a substrate as illustrated in FIG. 3. In step 201, the method 200 comprises providing the substrate comprising an outer surface for receiving a grapefruit seed based antimicrobial composition. The grapefruit seed based antimicrobial composition comprises ammonium hydrogen-fluoride, phosphoric acid, sodium dodecyl benzene sulfonate, 94 volume percent ethanol, crushed grapefruit seed extract, anionic surfactant and water. In step 202, the method 200 comprises treating the outer surface of the substrate with the grapefruit seed based antimicrobial composition. In step 203, the grapefruit seed based antimicrobial composition establishes a chemical connection with silicates on the outer surface or coatings on the outer surface to form a solid layer. In step 204, the method 200 comprises sealing the algal growth or preventing the algal formation by the said solid layer incorporated using grapefruit seed based antimicrobial composition. The grapefruit seed composition for preventing algal growth, which addresses the problem by inhibiting the photosynthesis process in the algae effectively for a longer duration. In an embodiment, the substrate may comprise ceramic tiles, bricks, concrete, natural stones, paving stones and the like.
    The existing composition or known prior art for preventing algal growth on the stone surface are unable to inhibit photosynthesis process of the algae completely, wherefore the algae will reproduce and grow again over a period. The present invention discloses a grapefruit seed composition for preventing algal growth, which addresses the problem by inhibiting the photosynthesis process in the algae effectively for a longer duration.
    Grapefruit seed extract is a superior surface disinfectant that has been proven 10 times
    DK 2017 00142 A1 more effective at preventing household germ such as algal formation than other known chemical disinfectant. Further, the grapefruit seed extract effectively disinfect against algae in kitchen surface, bathroom surface or even in the car.
    The anti-algal effect of the present composition is long lasting and durable. For example, the composition of the present invention blocks the possible growth of algae and other undesirable surface deposits for up to a period of ten years, without any need for retreatment during this period. Furthermore, treatment with the composition of present invention seals the small microscopic pores between the cracks and crevices on the surface of tiles, bricks, concrete or stones. The sealing layer prevents the ingress of water, and also protects the treated surface from frost damage, thereby increasing the lifetime of the paving stones, tiles, concrete and brick surface. The surfaces treated with the composition get self-cleaned and prevent algal growth, green pad and moss growth on the surface.
