DESCRIPTION

Sanitary Agent

Field of the Invention

The present invention relates to a sanitary agent for cleaning, disinfecting and / or perfuming a sanitary apparatus.

In particular, the present invention relates to a sanitary agent comprising an active body, which can be solid or semi-solid (more or less pasty), and which can adhere to an inner wall of a toilet bowl or urinal and remain adhered for a high number of water discharges, dissolving a small part of it each time, until it is completely consumed.

Prior art

Sanitary appliances, for example toilet bowls or urinals fixed to a wall, have to undergo repeated cleaning and disinfection operations so that they can maintain adequate hygienic conditions.

The prior art comprises the suspension of sanitary agents by means of hooking devices placed in the toilet bowl, if this exists; The issuance of the sanitary agent occurs in each water discharge operation to the cup.

Sanitary agents are also known which are fixed to the perimeter edge of the toilet bowl by means of a support; usually, said sanitary agents are inserted in particular devices, such as cages, provided with the support means, for example, a plastic anchor, and which also include grooves and / or holes that allow a part of the sanitary agent to be released in each discharge of water.

When subjected to the action of the water that irrigates the toilet bowl, the sanitary agents described above enrich the water with the substances contained in the agents, thus providing the necessary elements for detersion, decalcify, deodorize and / or disinfect the cup.

However, the hygienic devices described above have some drawbacks, such as not guaranteeing an adequate anchorage to the outer edge of the cup due to the fragility of the support means, so that an accidental fall of the sanitary agent contained in the apparatus can occur. sanitary toilet bowl.

In addition, these devices are neither very practical nor very hygienic; during manual cleaning of the edge of the toilet bowl, or during cleaning of the inside of the toilet using the toilet brush, the support means attached to the edge of the cup can be accidentally moved and, consequently, must be replaced on your site In addition, when replacing the sanitary agent once consumed, it is necessary to act manually, with the consequent operational and hygienic difficulties for the user, since the devices are often placed in poorly accessible places, or in any case not ideal from the point of hygienic view

In addition, it is difficult to apply these devices to the urinals, since they do not usually have raised edges or pieces to which the support means can be fixed. In the case of urinals or urinal cups, pads are usually used placed at the bottom, at the point of drainage. However, these tablets are usually dragged by the discharge of water and also cause unwanted splashes.

Recently, alternative solutions have been sought to eliminate the presence of the devices that have a support means to be fixed to the outer edge of the cup.

The prior art comprises some solutions to the problem described above, in which sanitary agents, in particular solid or semi-solid soaps, can stably adhere to the inner wall of a toilet or urinal cup so that they are subjected to discharges. regular water

European Patent EP 1 086 199, in the name of Buck-Chemie GmbH, describes a sanitary agent that can be applied directly on the surface of the sanitary apparatus, wherein said sanitary agent has a viscosity of at least 15,000 mPas and comprises an adhesion promoter, such as poly oxy alcohol, cellulose, etc. However, this excess viscosity may not be able to guarantee proper removal of lime deposits and a homogeneous distribution of the detergent contained in the sanitary agent. Other attempts are disclosed in EP-A-2 141 221 and WO 2008/125451.

In addition, during use, the sanitary agent deforms, causing the constituent components to drip down in an unwanted manner. Another disadvantage follows from the fact that, in order that it can be properly applied to the part of the sanitary apparatus, the sanitary agent described in the patent application necessarily requires the use of a dosing system, usually constituted by a material

rigid plastic, which implies an unwanted and significant use of plastic material.

Therefore, an alternative that allows for good adhesion should be sought, while at the same time guaranteeing sanitary hygienic treatments of the sanitary apparatus that are satisfactory.

For example, the international patent application, published under number W02008 / 100393 (corresponding to application US2008 / 0190457), in the name of Johnson & Sons, discloses a solid soap capable of adhering to the surface of the cup and At the same time, ensure adequate washing; however, the soap necessarily contains a very high amount of solid surfactant, in particular an alkylbenzene sulphonate anionic surfactant (known as LAS), comprised between 75% and 99% by weight with respect to the weight of the soap, in order to allow sufficient adhesion to the surface of the cup.

This high percentage of anionic surfactants carries high costs, as well as a negative environmental impact, especially when benzene-derived substances are used, such as the LAS surfactants mentioned above.

The technical problem still persists of having a sanitary agent that: a) exerts a satisfactory and lasting cleaning and / or scented action and / or disinfection of a sanitary device, b) does not require considerable manual operations for the elimination of possible parts residual adhesive of the sanitary agent at the end of its use, and c) present a part that adheres properly to the internal surface of a sanitary appliance during its use, and in particular d) has a reduced environmental impact and, in particular, allows an adhesive action strong while using a percentage of anionic surfactants present in the relatively very low composition.

Therefore, the objective of the present invention is to make known a sanitary agent for the treatment of a sanitary apparatus that constitutes an alternative to the solutions provided by the documents according to the prior art mentioned above.

In particular, the objective of the present invention is to disclose a sanitary agent for the treatment of a sanitary apparatus, wherein said sanitary agent comprises at least one adhesive component and at least one component useful for the treatment, the adhesive component being able to allow the sanitary agent to remain adhered during a large number of water discharges to a sanitary apparatus in any way and, at the same time, once the sanitary agent component used for the treatment, easily dissolve in the water of subsequent discharges.

Description of the invention

In a first aspect, the present invention relates to a sanitary agent that is used for detersion, disinfecting and / or perfuming a sanitary apparatus.

The present applicant has discovered that a sanitary agent for the treatment of a sanitary apparatus, comprising an active, solid or semi-solid body, which includes a treatment compound that has at least one active element for the treatment of the sanitary apparatus and at least one non-ionic surfactant, characterized in that the treatment composition further comprises at least one adhesive element derived from rosin resin (pine resin), dispersed in the active body material and intended to effect the adhesion of the active body to the wall of the sanitary apparatus, so that the adhesion is maintained during a high number of water discharges and the sanitary agent dissolves substantially completely at the end of the operating cycle thereof without having a negative impact on environment.

In this context, and in the appended claims, the term "sanitary appliance" refers to a toilet bowl, a urinal cup, a urinal or any other similar device, which is generally subjected to water discharges in order to maintain it. clean and in optimal hygienic conditions.

In this context, and in the appended claims, the term "treatment of a sanitary appliance" refers to cleaning, sanitation, disinfection, perfuming and decalcification, and other similar operations applicable to the sanitary appliance.

In this context, and in the appended claims, the term "active element for treatment" refers to an element intended for cleaning, detersion, foaming, scented, deodorization, disinfection, water coloring, polishing, or any other soluble element. in water and useful for the treatment to which the sanitary apparatus intends to undergo.

In this context, and in the appended claims, the term "semi-solid body" refers to a body of pasty consistency or that has a consistency that allows its shape to be modified by manual pressure, but at the same time allows it to maintain the shape at over time, even after the action of weak external forces, such as a discharge or emptying of water.

Thus, whatever the shape of the wall of the sanitary apparatus to which the sanitary agent intends to adhere, the shape of the sanitary agent can be adequately modeled from the shape of the wall to ensure good adhesion. This form can be maintained over time, except for the reduction of its mass due to its dissolution by the action of the discharge water.

The sanitary agent of the present invention can be consumed progressively and appropriately in each discharge of water from the sanitary apparatus, so that firstly the active element for the treatment of the sanitary apparatus is progressively dissolved in the discharge water. Then, after a series of water discharges, the adhesive element of the sanitary agent begins to be exposed to the action of water, which, in combination with the residual part of the treatment compound, allows the complete elimination of the adhesive element.

Thus, when the treatment compound has been consumed, only a small part of the adhesive element remains in contact with the wall of the treated sanitary apparatus, thus being easy to remove by means of washing tools suitable for the sanitary apparatus, such as brushes and Similar.

Best way to practice the invention

Example 1

Sanitary Agent 1 (Invention)

The first treatment compound for sanitary apparatus was prepared as follows:

Non-ionic surfactant Mergltal CS 25 (cethearet25) 70%

Sodium Sulfate 15.60%

Texapon V95 anionic surfactant alkyl sulfate 2.00%

Sodium Citrate 2.00%

Non-ionic surfactant Glucopon 50g 2.00%

Foaming DERIPHAT 160 C (Cognis) 1.00%

Perfume 3.00%

Coloring 0.40%

Wetting agent 2.00%

Linear rosin ester - Bremasin type 1205 2.00%

Compound 1 was prepared by mixing the various components in a two-arm laboratory mixer of 1 kg capacity at room temperature, allowing them to mix for approximately 30 minutes until obtaining a homogeneous, plastic and moldable paste, until obtaining sanitary agent 1 The sanitary agent 1, which is presented as a semi-solid active body, with a substantially flattened cylinder shape, with a diameter of the base surfaces of approximately 4 cm and a height (thickness) of approximately 0.4 cm, with a weight total of approximately 12 grams.

The sanitary agent 1 was adhered to the hard surface of the inner wall of a toilet bowl, after a discharge of water and pressing it against the wall of the sanitary apparatus to be treated for approximately ten seconds, in order to ensure good adhesion.

The sanitary agent 1 was subjected to a series of 100 homogeneous water discharges, which caused the progressive release until the total consumption of the treatment compound, leaving a rosin resin residue of less than 3% of the initial amount of rosin present in the sanitary agent; said rosin resin residue was easily removed by a toilet brush.

Thus, using the sanitary agent 1 according to the present invention, a good adhesion of the sanitary agent to the sanitary apparatus to be treated was obtained, even with a relatively very low percentage of anionic surfactant, as well as an effective sanitization of the sanitary apparatus; and, at the same time, it was not necessary to touch non-hygienic areas of the sanitary apparatus (the toilet bowl) with the hands to remove the residues of sanitary agent 1 at the end of its use phase. Finally, it was not necessary to use an applicator object to place the sanitary agent correctly without coming into contact with the walls of the toilet bowl.

Sanitary agent 2 (comparative example)

Agent 2 was prepared as agent 1, sanitary agent 2 being different from sanitary agent 1 because the formulation of the treatment compound did not include the adhesive element derived from the rosin resin.

The treatment compound 2 comprised:

Non-ionic surfactant Mergital CS 25 (cethearet25) 72.00%

Sodium Sulfate 15.60%

Texapon V95 ammonium surfactant alkyl sulfate 2.00%

Sodium 2.00%

Non-ionic surfactant Glucopon 50 G 2.00%

Sparkling DERIPHAT 160C (Cognls) 1.00%

Perfume 3.00%

Coloring 0.40%

Wetting agent 2.00%

The mixture was prepared in a manner similar to that described for example 1. The sanitary agent 2 obtained with the treatment compound 2, and having the same dimensions as the sanitary agent 1, was subjected to the same treatment as the sanitary agents.

In this case, differently from example 1, poor adhesion of the sanitary agent 2 to the surface to be treated is obtained. After some discharges, in fact, the sanitary agent 2 separated from the surface to which 10 had adhered.

From these examples, it can be seen that the addition to the treatment composition of a rosin resin derivative allowed sanitary agent 1 of the present invention to adhere satisfactorily to the surface to be treated, even in the presence of a percentage relatively very low anionic surfactant, 15 differently from what is seen with comparative sanitary agent 2, which does not comprise the rosin resin derivative.
