Description

DESCRIPTION TITLE: AQUEOUS DETERGENT AND / OR DISINFECTANT COMPOSITION FIELD OF INVENTION

[0001] The present invention relates to an aqueous detergent and / or disinfectant composition comprising at least two distinct quaternary ammonium compounds, at least one fluorinated non-ionic surfactant, and at least one biodegradable chelating agent. The present invention also relates to the use of said composition, as well as a method for using it, for cleaning and / or disinfecting surfaces, preferably hard surfaces, and / or medical devices. STATE OF THE ART

[0002] Cleaning and disinfection are essential to eliminate undesirable substances such as dirt and infectious agents (viruses, bacteria, fungi, etc.) that can pose risks to the public, for example, to patients and healthcare professionals in medical settings. Cleaning and / or disinfecting hard surfaces and medical devices can be carried out by applying a detergent and / or disinfectant solution that complies with current health standards and is minimally irritating, or even non-irritating, to the user. This solution must also be compatible with the materials to which it is applied, often repeatedly; that is, it must not compromise their integrity (texture, color, shape, durability, etc.).Examples of materials commonly used in the medical field include: polycarbonate (endocavitary probes, breathing masks, baby incubators, etc.), stainless steel (medical instrument trays, medical furniture structures, etc.) and the. plastics (bedpans, syringes, masks, etc.). Furthermore, the use of biodegradable ingredients helps limit the environmental impact of this composition. Finally, when cleaning and / or disinfecting medical devices with complex shapes, the detergent and / or disinfectant composition must be able to be applied evenly by spreading the drops over the surface, even in hard-to-reach areas.

[0003] There is therefore a real need to develop new aqueous detergent and / or disinfectant compositions that are biodegradable, free from volatile organic compounds (VOCs, such as alcohols, glycol ethers, etc.) and non-toxic, while being widely compatible with a large number of materials and possessing excellent usage properties, particularly in terms of wetting and spreading.

[0004] It has now been discovered that the combination of at least one quaternary ammonium compound of formula (I) and at least one quaternary ammonium compound of formula (II), defined below, with at least one non-ionic fluorinated surfactant and a specific chelating agent makes it possible to achieve the objectives mentioned above. This combination exhibits, in particular, good compatibility with a wide range of materials used, especially in the medical field, such as polycarbonate, plastics, and stainless steel, and also offers improved wetting and spreading properties.

[0107] [Fig. 2] Figure 2 groups together the photographs of the surfaces of the earthenware tiles at t = 0 and at t = 10 minutes during the gloss and trace tests. EXAMPLES

[0108] The present invention will be better understood by reading the following examples which illustrate the invention in a non-limiting way.

[0109] An example of a composition according to the invention has been prepared according to the table in Example 1 below.

[0110] Example 1: Example of a composition according to the invention (composition A) [OR I] Composition A according to the present invention was prepared from the ingredients indicated in Table 1 below, the contents of which are expressed as percentages by weight of active material relative to the total weight of the composition. [Table 1] Example 2: Study of the compatibility of the aqueous detergent and / or disinfectant composition with polycarbonate Materials and Methods

[0112] The compatibility of the composition according to the invention with polycarbonate was determined by a stress cracking test according to the following procedure. Polycarbonate test specimens are subjected to constant bending stress and then to cycles of immersion in a soaking and drying solution (stress cracking). This test allows for the evaluation of stress cracking of polycarbonate in a given environment. The appearance of cracks indicates the incompatibility of the soaking solution with the polycarbonate.

[0113] The test specimens under physical stress were thus immersed in composition A prepared above. Water and ethanol were used as controls. respectively negative and positive. The test specimens were also dipped in the commercial composition Surfa' safe Premium (from ANIOS, containing 0.3% by weight of didecyldimethylammonium chloride) for comparison. The tests were carried out at a temperature of 22 °C ± 3 °C. The polycarbonate-based specimens were subjected to 20 cycles, each cycle consisting of a 15-minute immersion in the dipping solution followed by 5 minutes of air drying. Results

[0114] Photographs of the surfaces of the polycarbonate-based specimens before (at t = 0) and after (at t = 20 cycles) the stress cracking tests are shown in Figure 1. The results of the stress cracking tests are summarized in the following table: [Table 2]

[0115] The results of the stress cracking test with the aqueous solution of composition A (described in Example 1) according to the invention show that the latter is compatible with polycarbonate in the same way as the commercial composition Surfa' safe Premium. Thus, the aqueous detergent and / or disinfectant composition according to the invention can be used and applied to polycarbonate, which is a material commonly used in the medical field. Tl Example 3: Study of the compatibility of the aqueous detergent and / or disinfectant composition with other materials Materials and Methods

[0116] The compatibility of composition A according to the invention with various materials was determined by an immersion test according to the following protocol. Test specimens, each made of a different material, are immersed in a soaking solution (immersion tests), which allows for the evaluation of the alteration of the different materials in a given environment. The appearance of alterations indicates the incompatibility of the soaking solution with the specimen material.

[0117] Three different immersion tests are carried out: A) The test specimens are subjected to 50 immersion cycles in the soaking and drying solution at a temperature of 22 °C ± 3 °C. Each cycle consists of a 15-minute immersion in the soaking solution followed by 5 minutes of air drying. This test simulates the repeated contact of a material with the soaking solution. B) The test specimens are immersed in the soaking solution for 8 hours at a temperature of 40 °C ± 2 °C. C) The test specimens are immersed in the soaking solution for 8 days at a temperature of 22 °C ± 3 °C.

[0118] Tests B and C correspond to accelerated aging tests which allow evaluation of a possible material degradation process and the resulting damage profile.

[0119] In all three immersion tests, the soaking solution is composition A described in example 1.

[0120] Material changes (appearance, color, deformation, stickiness, etc.) are evaluated by comparison with a new, non-immersed test specimen of the same reference. Results

[0121] The surfaces of the test specimens were photographed (not shown) before (at t = 0) and after the immersion tests (at t = 50 cycles for test A and after 8 hours or 8 days for tests B and C respectively). The results of the immersion tests are summarized in the following table: [Table 3]

[0122] The results above show that composition A (described in Example 1) according to the invention is compatible with the following materials: PVC, PMMA, TABS, HDPE, PP, PET, and anodized aluminum. Thus, the aqueous detergent and / or disinfectant composition according to the invention can be used and applied repeatedly to various materials commonly used in the medical field without altering their surface or properties. Example 4: Study of the corrosive action of aqueous detergent and / or disinfectant compositions on stainless steel Materials and Methods

[0123] The corrosive power of composition A according to the invention (described in Example 1) was evaluated using electrochemical tests by linear potential variation chronoamperometry. This test makes it possible to evaluate the pitting corrosive power of the composition on stainless steel surfaces. The corrosive power is characterized by the values ​​of the pitting and repassivation potentials.

[0124] The complete specific experimental setup consists of the following elements: three electrodes, including a stainless steel working electrode, a constant potential reference electrode and a counter electrode through which the faradaic current passes; a thermostated electrochemistry cell (OrigaCell, X140GL010); a potentiostat-galvanostat (OrigaElex - OGE01A, X130GL002CIAL); and a control unit (OrigaElex - OGEDRV, X130GL004CIAL).

[0125] The tests are carried out at a temperature of 22 °C ± 3 °C. The stainless steel used is Austenitic 304L with a polished and bright surface.

[0126] The electrochemical technique used is a potentiodynamic technique which consists of varying the potential of the working electrode linearly with time within a defined potential range in order to determine the pitting potentials and of repassivation of the solution being tested. The potential sweep speed is 0.2 mV.s 1 The maximum current density value is 500 pA.cm' 2 . Results

[0127] The results of the electrochemical tests by chronoamperometry are presented in the following table: [Table 4]

[0128] The pitting (446 mV) and repassivation (99 mV) potentials obtained for composition A (described in Example 1) according to the invention are more electropositive than those obtained for the 0.1% sodium chloride solution. Given that higher pitting and repassivation potentials indicate a less corrosive solution, these results demonstrate that composition A is not corrosive to stainless steel. Therefore, the aqueous detergent and / or disinfectant composition according to the invention is compatible with stainless steel, which is a material commonly used in the medical field. Example 5: Determining the spreading power of the aqueous detergent and / or disinfectant composition Materials and Methods

[0129] The spreading power of composition A according to the invention (described in Example 1) was evaluated by gloss and streak tests. Composition A (2.0 ± 0.5 g) is first deposited on a ceramic tile (19.7 x 19.7 cm, i.e., of a surface area of ​​388 cm 2 ) then spread over the surface using absorbent paper. The spreading power is characterized by the surface area covered by the composition.

[0130] The spreading power of composition A (described in example 1) was determined at t = 0 and t = 10 minutes. The spreading power of the commercial composition Surfa'safe Premium (from the company ANIOS, containing 0.3% by weight of didecyldimethylammonium chloride) was also determined at the same times for comparison. Results

[0131] Photographs of the surfaces of the earthenware tiles at t = 0 and t = 10 minutes are shown in Figure 2. The results of the gloss and trace tests are presented in the following table: [Table 5]

[0132] Composition A (described in Example 1) according to the invention provides better surface coverage than the commercial Surfa'safe Premium composition at t = 0 and t = 10 minutes. Upon application (t = 0), 100% of the surface is covered with Composition A of the invention, whereas only 70% of the surface is covered with the comparative composition. Similarly, 10 minutes after application, 62% of the surface is still covered with the composition of the invention, compared to only 20% with the comparative composition. Thus, the aqueous detergent and / or disinfectant composition according to the invention has superior spreading power compared to that of the commercial Surfa'safe Premium composition.
