Description
本揭露是有關於一種消臭組成及消臭方法，且特別是有關於一種能同時消除硫化氫及甲醛造成之臭味的消臭組成及其使用方法。 The present disclosure relates to a deodorizing composition and a deodorizing method, and more particularly to a deodorizing composition capable of simultaneously eliminating the odor caused by hydrogen sulfide and formaldehyde and a method of using the same.
除臭劑市場規模持續擴大。臭味有多種不同的來源。例如具有蛋腐敗臭味的硫化氫(hydrogen sulfide；H2S)可能來自糞便、下水、屁、寵物、口臭、菸臭等。具有刺激性臭味的甲醛(formaldehyde；HCHO)可能來自接著劑、建材、防腐劑等。臭味往往造成人的不適感，因此需要使用除臭劑消除造成異味的來源。 The market for deodorants continues to expand. There are many different sources of odor. For example, hydrogen sulfide (H 2 S) having an egg odor may come from feces, sewage, farts, pets, bad breath, smoke odor, and the like. Formaldehyde (HCHO) having a pungent odor may be derived from an adhesive, a building material, a preservative, and the like. Odors often cause discomfort, so deodorants are needed to eliminate the source of odors.
使用化學原料的除臭劑對人體有不良影響，因此業界發展天然原料。舉例來說，天然材料單寧酸與兒茶素可分別消除硫化氫與甲醛臭味。然而，單寧酸與兒茶素容易互相縮合聚合反應，會喪失各自的除臭效果，無法長期穩定保存。因此目前市場沒有能同時消除硫化氫與甲醛臭味的天然除臭劑。 Deodorants using chemical raw materials have adverse effects on the human body, so the industry develops natural raw materials. For example, the natural materials tannic acid and catechin can eliminate hydrogen sulfide and formaldehyde odor, respectively. However, tannic acid and catechins are easily condensed and polymerized with each other, which loses their respective deodorizing effects and cannot be stably stored for a long period of time. Therefore, there is currently no natural deodorant capable of simultaneously eliminating the odor of hydrogen sulfide and formaldehyde.
本揭露係有關於一種消臭組成及消臭方法。消臭組成可安定儲存，展現穩定的除臭功效。 The disclosure relates to a deodorizing composition and a deodorizing method. The deodorizing composition can be stored stably and exhibits a stable deodorizing effect.
根據本揭露之一實施例，提出一種消臭組成，其包括一鹼性溶液、一單寧酸、一兒茶素及一安定劑。安定劑包括聚乙二醇。 According to an embodiment of the present disclosure, a deodorizing composition comprising an alkaline solution, a tannic acid, a catechin, and a stabilizer is provided. Stabilizers include polyethylene glycol.
根據本揭露之另一實施例，提出一種消臭方法，其包括單獨使用一消臭組成進行消臭。消臭組成包括一鹼性溶液、一單寧酸、一兒茶素及一安定劑。安定劑包括聚乙二醇。 According to another embodiment of the present disclosure, a deodorizing method is proposed which includes deodorizing using a deodorizing composition alone. The deodorizing composition includes an alkaline solution, a tannic acid, a catechin and a stabilizer. Stabilizers include polyethylene glycol.
為了對本揭露之上述及其他方面有更佳的瞭解，下文特舉較佳實施例，並配合所附圖式，作詳細說明如下： In order to better understand the above and other aspects of the present disclosure, the preferred embodiments are described below in detail with reference to the accompanying drawings.
根據實施例是提供一種消臭組成，是可穩定儲存之硫化氫與甲醛雙效型清除劑，能用以同時消除硫化氫及甲醛造成的臭味，且其使用天然植物萃取物質為材料，對人體無害，也對環境無不良影響，是環保的組成配方。 According to an embodiment, the invention provides a deodorizing composition, which is a double-effect type scavenger of hydrogen sulfide and formaldehyde which can be stably stored, can be used for simultaneously eliminating odor caused by hydrogen sulfide and formaldehyde, and uses natural plant extracting material as a material, The human body is harmless and has no adverse effects on the environment. It is a composition formula for environmental protection.
根據實施例，消臭組成包括一鹼性溶液、一單寧酸、一兒茶素、及一安定劑。 According to an embodiment, the deodorizing composition comprises an alkaline solution, a tannic acid, a catechin, and a stabilizer.
一實施例中，單寧酸包括氧化單寧酸。對單寧酸進行氧化所得到的氧化單寧酸除硫化氫效果佳。氧化單寧酸的製造 方式可包括在鹼性溶液中將單寧酸氧化以得到氧化單寧酸。此用以氧化單寧酸的鹼性溶液包括碳酸鈉溶液、碳酸氫鈉溶液、檸檬酸鈉溶液、或上述之組合。鹼性溶液亦可用作緩衝劑。 In one embodiment, the tannic acid comprises oxidized tannic acid. The oxidized tannic acid obtained by oxidizing tannic acid has a good effect in addition to hydrogen sulfide. Manufacture of oxidized tannic acid Means can include oxidizing the tannic acid in an alkaline solution to obtain oxidized tannic acid. The alkaline solution for oxidizing tannic acid includes sodium carbonate solution, sodium hydrogencarbonate solution, sodium citrate solution, or a combination thereof. An alkaline solution can also be used as a buffer.
植物的皮、根、莖、葉、果殼等富含單寧酸，經過萃取、濃縮和過濾後，可以得到植物單寧，其化學結構是屬於水解單寧，均為多OH基芳香族化合，這些芳香族多OH基化合物在鹼液的進一步作用，有可能水解為分子量更小的連三酚和鄰二酚類的衍生。這些小分子的多OH基酚式結構化合物在鹼性溶液中很容易被氧化為醌式結構，可在氧化過程中充當良好的載氧體。這種酚醌轉化的結構使其具有了催化氧化硫化氫為元素硫的催化特性。故可以用做除硫配方。 The skin, roots, stems, leaves and husks of plants are rich in tannic acid. After extraction, concentration and filtration, plant tannins can be obtained. The chemical structure is hydrolyzed tannins, all of which are poly-OH-based aromatic compounds. Further, these aromatic poly-OH-based compounds may be hydrolyzed to a lower molecular weight derivative of dihydric phenols and o-diphenols in the lye. These small molecule polyoxophenolic structural compounds are easily oxidized to a quinoid structure in an alkaline solution and serve as a good oxygen carrier during the oxidation process. This phenolphthalein-converted structure has catalytic properties for catalytic oxidation of hydrogen sulfide to elemental sulfur. Therefore, it can be used as a sulfur removal formula.
兒茶素可用以消除甲醛，藉此移除甲醛造成的臭味。兒茶素在鹼性條件下除甲醛效果佳，但是易與氧化後單寧酸發生聚合，影響消臭之功能。根據本揭露實施例，可使用安定劑避免兒茶素與單寧酸(或氧化單寧酸)之間發生聚合反應，使兒茶素與單寧酸(或氧化單寧酸)能長時間維持各自的消臭功能。 The catechins can be used to eliminate formaldehyde, thereby removing the odor caused by formaldehyde. The catechin has good effect in removing formaldehyde under alkaline conditions, but it is easy to polymerize with tannic acid after oxidation, which affects the function of deodorization. According to the disclosed embodiments, a stabilizer can be used to prevent polymerization between catechin and tannic acid (or oxidized tannic acid), so that catechin and tannic acid (or oxidized tannic acid) can be maintained for a long time. Their respective deodorizing functions.
實施例中，安定劑是聚乙二醇(poly(ethylene glycol)，PEG；CAS NO：25322-68-3)，或者包括聚乙二醇。聚乙二醇具有以下化學結構：
聚乙二醇用以抑制消臭劑主成份兒茶素與單寧酸之間發生縮合反應，避免失去除硫化氫和除甲醛效果，增加除臭劑的儲存安定性。 Polyethylene glycol is used to inhibit the condensation reaction between the main components of the deodorant, catechin and tannic acid, to avoid the removal of hydrogen sulfide and formaldehyde removal, and to increase the storage stability of the deodorant.
適量的聚乙二醇能提供適當的微胞立體障礙，且安定劑醚類的氧(O)與兒茶素及單寧酸間的苯酚上羥基(OH)增加了氫鍵(hydrogen bond)，皆能避免兒茶素與單寧酸之間的聚合反應。 Appropriate amount of polyethylene glycol can provide appropriate microscopic steric hindrance, and the oxygen (O) of the stabilizer ether and the hydroxyl group (OH) on the phenol between catechin and tannic acid increase the hydrogen bond. The polymerization between catechin and tannic acid can be avoided.
實施例中，聚乙二醇的重量平均分子量(Weight-average Molecular Weight；Mw)可為200~400。舉例來說，聚乙二醇的重量平均分子量可為200、300、或400。過小重量平均分子量的聚乙二醇(即溶液黏度過低)無法提供足夠的立體障礙，而過大重量平均分子量的聚乙二醇(即溶液黏度過高)無法溶解在水溶液中，因此無法對兒茶素與單寧酸造成適當的穩定效用。 In the examples, the weight-average Molecular Weight (Mw) of the polyethylene glycol may be 200 to 400. For example, the polyethylene glycol may have a weight average molecular weight of 200, 300, or 400. Too small weight average molecular weight polyethylene glycol (ie, solution viscosity is too low) does not provide sufficient steric hindrance, and polyethylene glycol with excessive weight average molecular weight (ie, solution viscosity is too high) cannot be dissolved in aqueous solution, so it is impossible to Tea and tannic acid cause appropriate stabilizing effects.
實施例中，兒茶素：聚乙二醇的重量比是1：0.1~10，例如1：0.1~4。 In the examples, the weight ratio of catechin to polyethylene glycol is 1:0.1 to 10, for example, 1:0.1 to 4.
消臭組成使用的鹼性溶液包括碳酸鈉溶液(Na2CO3 solution)、碳酸氫鈉溶液(NaHCO3 solution)、檸檬酸鈉溶液、或上述之組合。鹼性溶液可用作緩衝劑。 The alkaline solution used for the deodorizing composition includes a sodium carbonate solution (Na 2 CO 3 solution), a sodium hydrogencarbonate solution (NaHCO 3 solution), a sodium citrate solution, or a combination thereof. An alkaline solution can be used as a buffer.
安定劑可更包括雙醣類物質，例如海藻糖等。安定劑可更包括硫辛酸。安定劑可包括雙醣類物質與硫辛酸的任意組合。 The stabilizer may further include a disaccharide such as trehalose. The stabilizer can further include lipoic acid. The stabilizer can include any combination of a disaccharide and lipoic acid.
消臭組成為鹼性，例如pH值8~12，例如pH值9~11。 The deodorizing composition is alkaline, for example, pH 8-12, such as pH 9-11.
消臭組成的溶液黏度也與溶劑(例如可溶解兒茶素、單寧酸的水溶劑)、或各成分的使用比例有關。需適當調整比例以得到能對兒茶素與單寧酸穩定效用的消臭產品。 The viscosity of the solution of the deodorizing composition is also related to the solvent (for example, a water solvent which dissolves catechin, tannic acid), or the ratio of use of each component. Properly adjusted to obtain a deodorizing product that can stabilize the effect of catechin and tannic acid.
由於根據實施例由消臭組成製得的消臭液產品可穩定儲存，因此消費者可單獨使用消臭組成直接進行消臭，例如將液態產品噴灑在環境中，或是靜置揮發至環境中，以同時消除硫化氫及甲醛造成的臭味。而不需要像使用一般的複合消臭產品，在使用前得將不同分開的組成混合在一起之後才能達到同時消除硫化氫及甲醛臭味的目的。根據實施例之消臭組成所使用之原料符合各項國際環保、安全性及禁用化學物質測試標準，並可應用於各種環境場所，例如漁市、雞場、牧場和資源回收廠，以及一般家庭中：廚房或浴廁等。因此相較於一般複合消臭產品，根據實施例之消臭組成製得可穩定儲存的消臭液產品，使用方法簡單且便利，對人體無害且環保，更加提高消費者的選購意願。 Since the deodorant product prepared from the deodorizing composition according to the embodiment can be stably stored, the consumer can directly deodorize using the deodorizing composition alone, for example, spraying the liquid product in the environment or standing and volatilizing into the environment. To eliminate the odor caused by hydrogen sulfide and formaldehyde at the same time. It is not necessary to use a general composite deodorizing product, and it is necessary to mix different components separately before use to achieve the purpose of simultaneously eliminating hydrogen sulfide and formaldehyde odor. The raw materials used in the deodorizing composition according to the examples meet the international environmental protection, safety and banned chemical testing standards, and can be applied to various environmental places, such as fish market, chicken farm, pasture and resource recycling plants, and general households. Medium: kitchen or bathroom, etc. Therefore, compared with the general composite deodorizing product, the deodorizing liquid product can be stably stored according to the deodorizing composition of the embodiment, and the using method is simple and convenient, harmless to the human body and environmentally friendly, and the consumer's willingness to purchase is further enhanced.
