Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cleaning composition for raw feathers that has excellent degreasing power and deodorizing effect and can impart a good texture to feathers after washing.

[Conventional technology and its problems]

In general, the raw feathers of ducks, geese, ducks, swans, chickens, etc. are contaminated with oil-soluble dirt such as wax and oil, as well as dirt, sand, dust, feces, urine, blood, bacteria, and pests. These can cause foul odors. Duvet,
In order to obtain feathers for use in down pillows, down wear, etc., these dirt adhering to the raw feathers must be washed and removed. If removal of these stains is insufficient, a bad odor will occur and the product value will be reduced.

The dirt adhering to the raw feathers is removed by removing dirt, sand, dust, etc. in the drying and dust removal process, and then by washing and rinsing in the washing process. The detergent used in the washing process is required to have degreasing power and deodorizing effect, and if the detergent is insufficiently effective, odor will remain on the feathers and reduce the product value. Cleaning agents used to remove these stains include, for example, a mixture of α-olefin sulfonate and higher alcohol or alkylphenol oxidized ethylene adduct (Japanese Unexamined Patent Publication No. 55-2622
6), a mixture of an α-olefin sulfonate, an alkylbenzene sulfonate, and an ethylene oxide-based ether type nonionic surfactant (Japanese Patent Publication No. 51-22087).

In this way, specific anionic activators and nonionic activators are used in combination, but sufficient effects are not obtained.
If the detergent concentration is increased to obtain degreasing and deodorizing effects, excessive feather fat will be removed, damaging the feathers during the drying and sorting process, and reducing the product value. Furthermore, the prior art required softening treatment after cleaning. Desirable detergents for feathers are ones with excellent degreasing power and deodorizing effect at normal detergent concentrations;
At present, there is no detergent that satisfies these demands, and does not impair the texture of the product.

[Means for solving problems]

Therefore, the present inventors conducted intensive research to obtain a detergent composition for raw feathers that has degreasing power and excellent deodorizing effect and does not impair the texture. The inventors have discovered that a composition containing the same proportions has an excellent cleaning effect, leading to the present invention.

That is, the present invention includes an alkylamine oxide (A) represented by the formula (I) and an anionic activator (B) as essential components, and the weight ratio of the components (A) and (B) is A. /B

It is obtained by oxidizing the corresponding tertiary amine, and in the present invention, the oxidation reaction with an aqueous hydrogen peroxide solution was used.

Examples of the alkylamine oxide of component (A) include lauryl dimethylamine oxide, lauryl diethylamine oxide, coconut fatty acid alkyl dimethylamine oxide, coconut fatty acid alkyl dimethylamine oxide, and hardened beef tallow fatty acid alkyl dimethylamine oxide.

〔Effect of the invention〕

The feathers treated with the cleaning agent of the present invention have a small residual fat percentage, are appropriately degreased, do not require softening treatment, and do not generate any strange odor over a long period of time when raked. Furthermore, since the texture of the feathers is not impaired, its practical value is extremely high.

〔Example〕

The present invention will be explained in detail below using Examples, but the present invention is not limited to these Examples.

Example 1 Table 1 shows the results of washing raw feathers with different ratios of sodium alkyl sulfate and alkyl amine oxide. White Booth and Gray Booth from China were used as raw feathers. The cleaning conditions were as follows: Add 200 ml of water to 5 g of raw feathers (bath ratio 1:40), add 1.5% of each ingredient with the composition shown in Table 1 to the raw feathers, and rinse in a sflavometer at 60°C for 30 minutes. Cleaning was carried out using a Toyo Seiki model). After washing, the washing solution was drained, 200 m7 of water was added, and the sample was rinsed at 40°C for 10 minutes, followed by rinsing a total of 5 times in the same manner. After rinsing, the feathers were dried at 105° C. for 2 hours, and the odor was evaluated and the residual fat percentage was measured using a Soxhlet extractor using dichloromethane as a solvent.

The odor was evaluated using the following 4-level evaluation by five panelists.

◎ Feathers hardly do it. ○ Feathers do it a little. △ Feathers do it. A particularly remarkable removal effect was observed in 60/40 to 4.
It was in the range of 0/60.

Example 2 Table 2 shows alkylamine oxide (average carbon number 01□)
and various anionic surfactants within the preferred mixing ratio of 50150, and a comparative product using a combination of alkylamine oxide and nonionic surfactant, as well as other surfactants other than alkylamine oxide. The produced white booth and gray booth were washed under the same conditions as in Example 1, and the residual fat percentage, odor, and texture were evaluated.

The preference of texture was evaluated by 10 female panelists through pairwise comparison with a standard, and scores were given according to the following evaluation water rate, based on the total score of the 10 panelists.

+2: I like it better than the standard +1 = Slightly better than the standard 0: Same as standard -1- I dislike it a little more than the standard -2: Dislike it more than the standard
