    [0002] Water-soluble capsule containing a solution of an agent for the treatment of swimming pool water
    [0003]
    [0004] The present invention relates to a water-soluble capsule containing a solution of an agent for the treatment of swimming pool water, which allows the solution to be handled in a safe manner and facilitates the use of the exact dose of the agent.
    [0005]
    [0006] Background of the invention
    [0007]
    [0008] It is common to use different compositions for water treatment and to try to avoid the development of algae and microorganisms in the water of swimming pools and spas.
    [0009]
    [0010] These compositions can be dosed in tablets and granules such as those defined in the patent with publication number US2003 / 0156981. Said application describes a compact product comprising algaecide products soluble in water and dispersed in a tablet. In said request it is relevant that the algaecide, is in solid form since it is intended to be retained in the filter so that it eliminates the phosphates of pool water that circulates through the filter.
    [0011]
    [0012] In the document with publication number WO2009042752 methods for the control of pH in water and for controlling the algae population are described by a synergistic composition of a lanthanide compound and a salt of a transition metal. Preferably these salts are used in solid form, more preferably, they are applied in the form of a pre-filled sealed cartridge. In the state of the art the problems of adding algicide in liquid form are explained.
    [0013]
    [0014] Finally, the application WO2014071240 describes a composition for water treatment comprising, among other elements, a phosphate eliminating substance that is included in a sealed pouch formed by a water soluble film. The bag is applied directly to the water and dissolved by releasing the compounds to treat the water. The composition included in the water-soluble sachets contains a composite formed solid granules that flow freely and which has both the phosphate-removing substance and a flocculating polymer adhered. Then in this application the composition is formed by solid granules packed inside the bags of water-soluble film. Is The application does not describe a Kquida composition contained in a water-soluble film.
    [0015]
    [0016] Therefore, the objective of the present invention is to develop a solution of an active agent for the treatment of swimming pool waters, contained in a water-soluble capsule.
    [0017]
    [0018] Description of the invention
    [0019]
    [0020] With the water-soluble capsule of the invention containing a solution of the agent for the treatment of water, it is respectful with the environment, since the products are in a very high concentration. This allows the use of less quantity of raw materials, packaging and energy in its production. It is very relevant from the ecological point of view to be able to reduce the volume of containers and packaging due to the great environmental impact of these residues, due to the large volume they represent. With the capsule of the present invention, when the agent for the treatment of water is concentrated, the load weight is reduced by 85% as well as the storage and transport space.
    [0021]
    [0022] With the capsule of the invention, a control of the product used and a reduction of the cost of waste management is carried out.
    [0023]
    [0024] Besides that the active principle is inside a capsule, it allows the safe manipulation, without being necessary the contact with the chemical product. The use is easy and comfortable.
    [0025]
    [0026] When the capsule of the invention is added to water, for example to the water of a pool, the water-soluble capsules are dissolved facilitating the dispersion and dissolution of the liquid solution contained therein. The present invention, having the active principle in the form of a solution facilitates the dispersion and dissolution of the agent for the treatment of water, in the water once released from the capsule.
    [0027]
    [0028] Therefore the first aspect of the invention relates to a water-soluble capsule consisting of an outer film containing a solution of an agent for the treatment of water, where:
    [0029] - the outer film comprises PVOH (polyvinyl alcohol) and
    [0030] the solution of the agent for the treatment of water comprises: an agent for the treatment of water selected from: an algicidal agent, a flocculating agent and a phosphate reducer or mixtures thereof and a solvent medium of the agent, selected from at least one of the following solvents: ethylene glycol, glycerol and polyglycols.
    [0031] A second aspect of the invention is the process for obtaining the water-soluble capsule of the invention comprising the steps of:
    [0032] a) mix until homogenization the solvent and the agent for the water treatment, in a mixer with constant agitation and controlled temperature comprised between 20 ° C and 25 ° C;
    [0033] b) filling the outer film with the mixture of step a) at a relative humidity between 35% and 45% and controlled temperature between 20 ° C and 25 ° C
    [0034] c) close the film by heat sealing.
    [0035]
    [0036] The third aspect of the invention is the use of the capsule of the first aspect of the invention for the treatment of water.
    [0037]
    [0038] Preferably the capsule is used in swimming pools and spas. Particularly the use in swimming pool water.
