Description

DETAILED DESCRIPTION

[0012] The deodorizing composition that is the subject of this invention comprises a mixture of alcohol and natural oils as active ingredients together with one or more excipient components and incorporated into an acceptable vehicle. The compositions under this invention can be manufactured using a process that involves mixing defined proportions of the components of the active ingredient and then adding each excipient component and incorporating them into an acceptable vehicle.

[0013] For the purposes of this invention, a deodorizing composition is defined as a composition that can neutralize or counteract an odor but does not mask it. Masking an odor means introducing a “masking” fragrance, which usually has a pleasant smell, and the intensity of the “masking” fragrance's smell modifies the unacceptable odor.

[0014] In turn, the terms “neutralize” and “counteract” indicate that the perceived intensity of the unacceptable odor is minimal or undetectable due to the presence of a neutralizing active ingredient, which may be present in concentrations that do not surpass the odor perception threshold and provide little or no odor, but which significantly reduces or eliminates the perception of the unpleasant odor. The deodorizing compositions under this invention provide both neutralize and counteract unpleasant odors in any application.

[0015] The active ingredient of the compositions under this invention is a mixture of established proportions of an alcohol and natural oils, one of which is coconut oil. The alcohol that makes up the active ingredient is selected from methanol, ethanol, isopropanol and mixtures thereof. In one form of the invention, the alcohol used for the active ingredient is ethanol. In another form of the invention, the alcohol used for the active ingredient is isopropanol. In another form of the invention, the alcohol used for the active ingredient is methanol. In another form of the invention, the active ingredient is an ethanol/methanol, methanol/isopropanol, or ethanol/isopropanol mix in equal or different ratios.

[0016] As far as the present invention is concerned, the term natural oil can be defined as an oleaginous substance of vegetable origin, rich in glycerol and fatty acids, liquid or solid at room temperature, which can be obtained from plant-based raw materials using known processes, such as distillation. The natural oils that make up the active ingredient are obtained from commonly known plants and are selected from coconut oil, cotton oil, palm oil, clove oil, bay leaf oil, lavender oil, jasmine oil, rose oil, pine oil, and eucalyptus oil, among others.

[0017] In one form of the invention, the natural oils used for the active ingredient are coconut oil and cotton oil in equal or different ratios. In another form of the invention, the natural oils used for the active ingredient are coconut oil and clove oil in equal or different ratios. In another form of the invention, the natural oils used for the active ingredient are coconut oil, clove oil, and cotton oil in equal or different ratios.

[0018] The ratio of alcohol to natural oils that make up the active ingredient can be 1:1; 1:2; 1:3; 2:1 or 3:1. In one form of the invention, the ratio of alcohol:natural oils used for the active ingredient is 1:1. In another form of the invention, the ratio of alcohol:natural oils used for the active ingredient is 1:2 or 2:1. In another form of the invention, the ratio of alcohol:natural oils used for the active ingredient is 1:3 or 3:1.

[0019] The active ingredient of the invention's compositions may be present in concentrations of between 5.0% and 95.0% (w/w) with respect to the overall composition, preferably between 20% and 70%, more preferably between 35.0% and 60.0%, and even more preferably between 40.0% and 55.0% (w/w) with respect to the overall composition. In one form of the invention, the active ingredient of the invention's composition is present in a concentration of 40.0% (w/w). In another form of the invention, the active ingredient of the invention's composition is present in a concentration of 48.0% (w/w) or 52.5% (w/w).

[0020] It will be evident to any person with knowledge of technical matters that concentrations of the active ingredient in the compositions under this invention may vary within these ranges and will depend on several factors including its intended use, the type of environment to be deodorized, and the type of excipient components and vehicle. Likewise, the active ingredient of the compositions under this invention may behave either as substance evaporator, disinfectant, bactericide, aromatic substance, or as an agent to form thin films on surfaces.

[0021] The active ingredient used in this invention, can be adapted, together with excipients and an acceptable vehicle, to obtain deodorizing compositions that can be used to neutralize or counteract bad odors. Excipients may include one or more surfactants, wetting agents, emollients, antioxidants, sequestrants, dispersants, dyes, pH regulators, and aromatic agents.

[0022] Excipient components of the deodorizing compositions under this invention are known and commonly employed by techniques for liquid compositions and are present in concentrations of between 10.0% and 90.0% (w/w) with respect to the overall composition, preferably between 30.0% and 70.0%, more preferably between 40.0% and 60.0%, and even more preferably between 45.0% and 55.0% (w/w) with respect to the overall composition. In one form of the invention, excipient components are present at concentrations between 35.0% and 65.0% (w/w).

[0023] Excipient components may include essences and/or fragrances that provide the compositions of the invention with a pleasant aroma. The essences and/or fragrances of these compositions could potentially act in association with the active ingredient but are not necessary for the active ingredient to exert its odor-neutralizing action. The essences and fragrances are those known and commonly used by techniques for creating liquid compositions, and may include floral essences, vanilla essence, mint essence, green apple essence, among others.

[0024] The excipient components of the compositions under this invention may include, among others, bleaching, bactericidal and disinfectant agents commonly known and used by the technique, including vinegar, apple cider vinegar, dicalcium phosphate, sodium diacetate, sodium bicarbonate and methylene blue. Additionally, the excipients of the compositions of this invention may include sequestering agents known and commonly used by the technical field, including EDTA.

[0025] For the purposes of this invention, the term acceptable vehicle refers to diluents such as purified water, alcohols, polyols, glycerin and mixtures thereof, which allow obtaining liquid compositions, either as solutions, emulsions, suspensions or dispersions. The alcohols and polyols that used in the acceptable vehicle of the compositions of this invention are those known and commonly employed in the technical field. In one form of the invention, the acceptable vehicle is a mixture of water and glycerin or a water:polyol mixture. In another form of the invention, the acceptable vehicle is purified water.

[0026] In one form of the invention, the deodorizing compositions are as follows:

TABLE-US-00001 TABLE 1 Component Range (% w/w) Active Ingredient Alcohol 5.0-50.0 Natural Oils 1.0-40.0 Excipient components 1.0-90.0

[0027] In an other form of the invention, the deodorizing compositions are as follows:

TABLE-US-00002 TABLE 2 Component Range (% w/w) Active Ingredient Ethanol 10.0-40.0  Natural Oils 3.0-30.0 Excipient components Apple cider vinegar 1.0-10.0 EDTA 0.1-10.0 Methylene blue 0.1-10.0 Sodium bicarbonate 0.1-10.0 Vanilla essence 0.1-15.0 Mint essence 0.1-15.0 Apple essence 0.1-15.0 Lavender essence 0.1-15.0 Purified water 5.0-95.0

[0028] The deodorizing compositions of this invention can be packaged in containers suitable for direct, drip or spray application using dispensers known in the technical field.

[0029] The invention also provides a method to neutralize or counteract bad odors on an object or in an environment, which requires putting an adequate amount of the deodorizing compositions of this invention in contact with the object or environment to be deodorized. In one form of the invention, the object to be deodorized with the compositions of this invention is a toilet, pipe, or washroom, and the environment is a closed environment where unpleasant odors are present.

[0030] Deodorizing compositions under this invention can be used in a wide variety of objects or environments where it is necessary to neutralize or counteract bad odors. As such, this invention also contemplates the use of deodorizing compositions to neutralize or counteract unpleasant odors from various sources, such as odors produced by pollution, by decomposing organic matter, or by aerobic or anaerobic bacteria.

[0031] In one form of the invention, the deodorizing compositions of the invention are applied directly to the water contained in a pipe or a toilet to neutralize the bad odors generated there. In one form of the invention, the deodorizing compositions can be used to neutralize the odors produced by animal or human excrement in a toilet, a washroom or a basin, for which an adequate amount of the deodorizing composition is applied before or during the disposal of excrement.

[0032] The following examples illustrate the invention, but in no way do they restrict its concept.

Examples

Example 1. Preparation of a Deodorizing Composition

[0033] 7.0 ml of coconut oil, 3.0 ml of clove oil and 14.0 ml of cotton oil were placed in container A. Then 9.0 m of vanilla fragrance; 4.0 ml of mint fragrance; 8.0 ml of green apple fragrance and 4.0 ml of lavender fragrance was added.

[0034] In container B, 2.0 grams of EDTA were dissolved in 9.5 ml of purified water and 1.5 grams of methylene blue, 5.0 grams of sodium bicarbonate, 9.0 ml of apple cider vinegar, and 24.0 ml of ethanol were added.

[0035] Finally, all the contents of container B were incorporated into container A to obtain 100 mL of deodorizing composition with the percentages (w/w) indicated in Table 3:

TABLE-US-00003 TABLE 3 Component % (w/w) Ethanol 24.0 EDTA 2.0 Coconut oil 7.0 Vanilla essence 9.0 Mint essence 4.0 Green apple essence 8.0 Clove oil 3.0 Apple cider vinegar 9.0 Sodium bicarbonate 5.0 Lavender essence 4.0 Cotton oil 14.0 Methylene blue 1.5 Purified water q.s. 100.0

Example 2. Deodorizing Compositions

[0036] Following the same process indicated in Example 1, the appropriate quantities were arranged to prepare 100 mL of three deodorizing compositions (T, W, Z), with the percentages (w/w) indicated in Table 4.

TABLE-US-00004 TABLE 4 % (w/w) Component T W Z Ethanol 20.0 23.0 30.0 EDTA 1.0 1.5 1.8 Coconut oil 5.0 9.0 6.0 Vanilla essence 8.0 6.0 7.0 Mint essence 3.0 3.0 5.0 Green apple essence 7.0 9.0 7.0 Clove oil 2.0 2.5 3.5 Apple cider vinegar 7.0 6.0 8.0 Sodium bicarbonate 3.0 4.0 6.0 Lavender essence 3.0 3.0 5.0 Cotton oil 13.0 18.0 12.0 Methylene blue 1.0 2.0 1.7 Purified water q.s. 100.0 100.0 100.0

Example 3. Sensory Analysis Test

[0037] Five trained evaluators performed a sensory analysis unpleasant odor test in an enclosed environment (unventilated bathroom) 2, 5, 10 and 15 minutes after excrement had been disposed of in a conventional toilet, to which 0.5 milliliters of the deodorizing composition in Example 1 had previously been added.

[0038] The trained evaluators entered the closed environment, perceived the odor to determine its intensity, and assigned it a score according to the scale in Table 5. The results obtained during the test can be found in Table 6.

TABLE-US-00005 TABLE 5 Odor scoring scale used by evaluators for the sensory analysis test Score Odor Description 0 Bad odor not present 10 Barely noticeable bad odor 20 Slight bad odor 25 Moderately bad odor 50 Strong bad odor 100 Extremely strong bad odor

TABLE-US-00006 TABLE 6 Sensory analysis test results Standard Evaluator A B C D E Average deviation Score at 25 25 20 10 20 20 6.1 the four 20 10 10 10 10 12 4.5 evaluated 0 0 10 0 0 2 4.5 moments 0 0 0 0 0 0 0

[0039] According to the test results, none of the trained evaluators perceived a strong or extremely strong bad smell after 2 minutes, so the deodorizing composition tested managed to neutralize the unpleasant odor in a short time.
