Description

Method for deodorizing using bagasse and deodorizing cleaning composition containing bagasse

The present invention relates to a method for deodorizing using sugarcane bagasse.

The odor in the living environment usually comes from volatile matter in the wastes and pollutants of transportation, industry, or households, and the secretions of animals and humans, which are also called odor components. In Taiwan’s "Enforcement Regulations of the Air Pollution Prevention and Control Law", odor pollutants are listed as air pollutants, and are defined as: pollutants that have an odor and are sufficient to cause disgust or other adverse emotional reactions. In Japan's "Odor Prevention Act", substances that cause unpleasant odors and harm the living environment are defined as odorous substances, and 22 substances including aldehydes are regulated.

The common odor molecules in the living environment can be divided into: (i) Organic nitrogen compounds, such as ammonia, trimethyl amine, methyl amine, ethyl amine and other molecules, usually have food waste, excrement or sewer Smell (ii) Organic sulfur compounds, such as hydrogen sulfide, methyl mercaptan, etc., usually have the smell of spoiled vegetables, excrement or sewers; (iii) Short-chain fatty acids, such as Isovaleric, Valeric acid, butyric acid and other molecules, usually have the smell of sweat, socks, and laundry; (iv) Aldehydes, such as acetaldehyde, 2-nonenal (2-nonenal) and other molecules, usually have bad odors such as the bad breath of smokers or drunken people, and the odor of aging (also known as the odor of the elderly); and (v) Aromatic hydrocarbons, such as styrene, xylene, toluene and other molecules, usually have the smell of gas or gasoline.

The methods currently used for deodorization include: (1) using physical adsorption to remove odor molecules; (2) using ozone to decompose odor molecules; (3) using microorganisms to decompose odor molecules; and (4) using Ultraviolet (ultraviolet) to photocatalytically decompose odor molecules. However, for the scalp odor, sweat odor, underarm odor and aging odor caused by the oxidation or decomposition of sweat and sebum (sebum) secreted by the human body, only deodorants or antibacterial agents can be used for individuals. Deodorant cleaning products can be used to cover up, block, or prevent odor generation by inhibiting the growth of bacteria, so the effect is usually very limited.

In recent years, many different types of dry shampoo products have appeared on the market. For example, dry shampoo products in dry powder form mainly use starch, aluminum silicate or talc. talc) and other ingredients to absorb excessive sebum on the scalp; and spray-type dry hair products, which usually only use organic solvents and fragrances to make the scalp feel cool and refreshing. Therefore, these dry hair products are effective in removing odors. It is limited, and it is easy to stick to the scalp and not easy to remove oil or odor molecules, so it may cause skin allergies, sebaceous glands, and even cause folliculitis.

On the other hand, Japan's Mitsui Sugar Co., Ltd. published in 2010 a method and its products for deodorizing using sugarcane extracts rich in sugarcane polyphenols. The sugarcane extract has been experimentally confirmed to be able to effectively adsorb organic nitrogen compounds, organic sulfides, aromatic hydrocarbons and other odor molecules, and is suitable for removing the fishy odor, smoke odor of meat or fish, and the odor of bedding.

Although the above-mentioned deodorizing products are available, relevant researchers in the field are still committed to developing materials with better deodorizing effects. In previous research, the applicant unexpectedly discovered that sugarcane bagasse (sugarcane bagasse) after de-sweetening and drying has excellent adsorption capacity for oils and odors, and has excellent properties of being easy to remove and not easy to remain in the human body. Therefore, it is expected It can be used as a cleaning product for absorbing grease and deodorizing.

Evaluation of the effectiveness of bagasse powder in deodorization

In this example, the applicant selected 2-nonanal, the main odor molecule in human body odors, as a representative, and evaluated the ability of bagasse powder to deodorize by measuring the adsorption capacity of bagasse powder for 2-nonanal. utility. In addition, the applicant also selected absorbent materials commonly used for deodorization in commercially available personal cleansing products for comparison. experimental method:

First, a 96 ppm 2-nonenal (2-nonenal) solution (purchased from Youhe Trading Co., Ltd.) was placed in a closed container and placed in a water bath at 37°C for 5 minutes. Next, the HS-SPME-GC analysis was performed using the method described in Item 1 of the "General Experimental Methods" to determine the volatile amount of 2-nonanal extracted without the adsorption of bagasse powder.

Next, place the two bagasse powders with particle size <270 μm and 270-550 μm prepared in item 1 of the above "General Experimental Materials" and 96 ppm 2-nonanal solution in a closed container. In the water bath at 37°C for 5 minutes, the bagasse powder can adsorb 2-nonanal. Next, the HS-SPME-GC analysis was performed using the method described in Item 1 of the "General Experimental Methods" to determine the volatile amount of 2-nonanal extracted after the bagasse powder was adsorbed.

The adsorption rate of bagasse powder to 2-nonanal is calculated by substituting the volatile amount of 2-nonanal measured with or without adsorption into the following formula (I): Formula (I) : A = (BC )/B × 100 where: A = adsorption rate (%) B = the volatile amount of 2-nonanal extracted without adsorption C = the volatile amount of residual 2-nonanal extracted after adsorption

The experiment was repeated 3 times, and the experimental data was expressed as "mean ± standard error of the mean (SEM)".

For comparison, bamboo charcoal powder and corn starch were also used to perform the same experiment once. result:

The adsorption rates of the two kinds of bagasse powders with different particle sizes and the other two adsorbents for 2-nonanal are shown in Table 2 below. Table 2. The adsorption rate of 2-nonanal by bagasse powder and other adsorbents Test material Adsorption rate(%) Bagasse powder (<270 μm) 67.3±11.5 Bagasse powder (270-550 μm) 71.8±7.5 Bamboo charcoal powder 99.1 corn starch 21.5

It can be seen from Table 1 that the adsorption rate of 2-nonanal by bagasse powder is only slightly lower than that of bamboo charcoal powder, and both are significantly better than those of corn starch. Example 2. Evaluation of the effectiveness of bagasse on oil absorption

In this embodiment, the applicant selected coconut oil and a conventional oil mixture used to simulate human sebum [also known as artificial sebum] (Deeksha et al. (2014), Recent Pat. Inflamm. Allergy. Drug Discov. , 8(1):48-58), and evaluate the effect of bagasse powder on oil absorption by observing the ability of bagasse powder to absorb coconut oil droplets and artificial sebum. In addition, the applicant also selected absorbent materials commonly used for oil absorption in commercially available personal cleansing products for comparison. A. Determination of oil droplet adsorption capacity: experimental method:

Take 1 g of bagasse powder (<270 μm), and then add 50 μL of coconut oil with a dropper to the bagasse powder, while observing the adsorption of oil droplets. For comparison, tapioca starch, corn starch, kaolin and bamboo charcoal powder were also used for the same experiment. result:

Through observation, it was found that the oil droplets were adsorbed immediately when they were dropped on the bagasse powder, showing a rapid adsorption speed; in contrast, the oil droplets were not absorbed when dropped on the bamboo charcoal powder, corn starch, kaolin, and tapioca starch. It is adsorbed immediately to maintain the complete droplet shape (see Figure 1), and is completely adsorbed after about 10 seconds. After the oil droplets are completely absorbed, the bagasse powder can be observed to be partially agglomerated and easy to remove; in contrast, the other four materials are still in the powder state (data not shown). B. Determination of the adsorption capacity of artificial sebum: Experimental materials: 1. Preparation of artificial sebum:

The applicant thoroughly mixed the components according to the formula shown in Table 3 below, and then heated it in a 70°C water bath until all the components were completely dissolved, thereby preparing an artificial sebum in the form of a clear solution. The artificial sebum thus obtained was used for the following adsorption test. Table 3. Formula of artificial sebum Component Content (wt%) Squalene 5 Wax esters Paraffin 10 Spermaceti 15 Triacylglycerides (triacylglycerides) Olive oil 20 Coconut oil 15 Fatty acids Stearic acid 7.5 Oleic acid 10 Cholesterol 17.5 experimental method:

The determination of the adsorption capacity of the three bagasse powders with different particle diameters for artificial sebum is mainly carried out with reference to the method described in Deeksha et al. (2014) (same as above) with slight modifications.

First, take 0.5 g of wool wool to simulate human hair, and use a micropipette to add 50 μL of artificial sebum dropwise to the wool. After the artificial sebum is completely absorbed by the wool, 0.1 g of bagasse powder is added and kneaded so that the bagasse powder is in full contact with the wool so that the artificial sebum can be absorbed. After 1 minute, tap the wool to remove the bagasse powder, and then use a commercially available oil-absorbing facial paper to absorb the remaining artificial sebum on the wool, and then use the weight of the oil-absorbing facial paper to estimate that the wool is absorbed by the bagasse powder. The remaining amount of artificial sebum (g).

The adsorption rate of bagasse powder to artificial sebum is calculated by substituting the measured residual amount of artificial sebum into the following formula (II): Formula (II) : E=[(FG )/F] × 100 where: E=Artificial sebum adsorption rate (%) F=The original amount of artificial sebum (40.5 g) G=The remaining amount of artificial sebum (g)

The experiment was repeated 3 times, and the experimental data was expressed as "mean ± standard error of the mean (SEM)".

For comparison, saponin was used for the same experiment three times, while bitter tea powder, tapioca starch, corn starch, kaolin, and bamboo charcoal powder were used for the same experiment once. result:

The adsorption rates of three kinds of bagasse powder with different particle sizes and other six kinds of adsorbents for artificial sebum are shown in Table 4 below. Table 4. Adsorption rate of bagasse powder and other adsorbent materials for artificial sebum Test material Adsorption rate(%) Bagasse powder (<270 μm) 78.8±12.0 Bagasse powder (270-550 μm) 88.9±11.0 Bagasse powder (>550 μm) 92.1±9.1 Saponin 83.9±5.2 Bitter tea powder 93.8 Tapioca starch 86.1 corn starch 85.3 Kaolin 84.0 Bamboo charcoal powder 41.6

It can be seen from Table 4 that the adsorption rate of bagasse powder for artificial sebum is similar to that of bitter tea powder, tapioca starch, corn starch, kaolin and saponin, and is significantly higher than that of bamboo charcoal powder.

Based on the above, the applicant believes that the bagasse powder is expected to have the potential to be used to develop products that absorb oil (especially human sebum). Example 3. Evaluation of the residue of bagasse powder after use

In this embodiment, wool is also used to simulate human hair to evaluate the condition of bagasse powder remaining on the hair after use. In addition, the applicant also selected absorbent materials commonly used for deodorization and oil absorption in commercially available personal cleaning products for comparison. experimental method:

This experiment is basically carried out with reference to the method described in item B of Example 2 above. The difference is: instead of measuring the total weight of bagasse powder after adsorption, and the amount of sebum residue of the wool yarn after adsorption of bagasse powder , And then substitute the following formula (III) to calculate the residue rate of bagasse powder on the hair after use: Formula (III) : H=[(IJK )/L] × 100 where: H= residue rate of bagasse powder ( %) I = total weight after adsorption (g) J = remaining amount of artificial sebum (g) K = weight of wool (0.5 g) L = original amount of bagasse powder (0.1 g)

The experiment was repeated 3 times, and the experimental data was expressed as "mean ± standard error of the mean (SEM)".

For comparison, bitter tea powder, tapioca starch, corn starch, kaolin, saponin, and bamboo charcoal powder were used for the same experiment once . result:

The residual rates of bagasse powder with three different particle sizes and six other adsorbents on the hair are respectively shown in Table 5 below. Table 5. Residual rate of bagasse powder and other absorbent materials on hair Test material Residual rate (%) Bagasse powder (<270 μm) 26.5±7.0 Bagasse powder (270-550 μm) 9.0±13.0 Bagasse powder (>550 μm) 20.0±10.5 Bitter tea powder 100 Tapioca starch 100 corn starch 100 Kaolin 76.4 Saponin 98.3 Bamboo charcoal powder 87.5

It can be seen from Table 5 that the residue rate of bagasse powder after use is significantly lower than that of other adsorbent materials.

Combining the results of Examples 2 and 3, it can be seen that the bagasse powder has excellent deodorizing and oil absorption capabilities at the same time, and it is easy to remove after use, and it is not easy to remain on the hair. In contrast, other adsorbent materials cannot have these three advantages at the same time. For example, although bamboo charcoal powder has excellent deodorizing ability, it has poor oil absorption ability and is easy to remain after use. Although bitter tea powder, tapioca starch and corn starch have good oil absorption capacity, they are also the easiest to remain. Example 4. Preparation and effectiveness evaluation of the cleaning composition of the present invention

In this example, the applicant further combined bagasse powder (270-550 μm) with a conventional absorbent material to prepare a cleaning composition containing bagasse powder, and used it with a commercially available dry cleaning composition. (dry shampoo) products to compare their effectiveness. experimental method:

First, according to the formula shown in Table 6 below, three cleaning compositions containing bagasse powder (ie, compositions 1 to 3) were prepared. Table 6. The formula of the cleaning composition of the present invention Component Composition 1 Composition 2 Composition 3 Content (wt%) Bagasse powder (270-550 μm) 1 20 50 Bitter tea powder 97 78 48 Bamboo charcoal powder 2 2 2

The adsorption capacity of compositions 1 to 3 for 2-nonanal, the adsorption capacity for artificial sebum, and the residual situation after use are as described in Example 1, Item B of Example 2, and Example 3, respectively. Method to evaluate. In addition, the commercial products La Focus 119 emergency dry hair powder (La Focus) and NATURIA dry hair mist (René Furterer) were also used in the same experiment. The experiment was repeated 3 times, and the experimental data was expressed as "mean ± standard error of the mean (SEM)". result:

The absorption rate of 2-nonanal and artificial sebum and the residual rate after use of the cleansing composition of the present invention and commercially available dry hair products are shown in Table 7 below, respectively. Table 7. Comparison of the cleansing composition of the present invention and commercial dry hair products Test product Bagasse content (wt%) Adsorption rate for 2-nonanal (%) Adsorption rate for artificial sebum (%) Cleaning composition 1 1 Not measured 62.8±18.9 Cleaning composition 2 20 46.1±1.9 76.0±5.2 Cleaning composition 3 50 56.5±2.3 76.8±2.3 La Focus 119 Emergency Dry Hair Loose Powder - Not measured 14.2±3.5 NATURIA Dry Hair Fog - Not measured 77.2±11

It can be seen from Table 7 that cleansing compositions 1 to 3 all have excellent adsorption capacity for artificial sebum, but only cleansing compositions 2 and 3 have significantly excellent adsorption capacity for 2-nonanal, and this adsorption capacity will increase with The increase of bagasse powder content becomes more and more obvious. This means that the bagasse powder plays an extremely important role in the deodorizing ability of the cleaning composition, and a slight addition of the bagasse powder can give a composition deodorizing ability and at the same time make it have excellent oil absorption ability. In contrast, the oil absorption capacity of commercially available dry hair products varies greatly, and none of them has the ability to deodorize.

The above and other objectives, features and advantages of the present invention will become apparent with reference to the following detailed description, preferred embodiments and drawings attached with the text, among which: Figure 1 shows the state of bagasse powder, kaolin, bamboo charcoal powder, corn starch and tapioca starch at the moment of contact with oil droplets, where A represents bagasse powder; B represents kaolin; C represents bamboo charcoal powder; D represents corn starch; and E represents Tapioca starch.
