Description

[Detailed description of the invention]

The present invention relates to a feather treatment agent having an excellent deodorizing effect, and in particular to a novel feather deodorization treatment agent with excellent practicality that can suppress the generation of off-odor over time in feather products over a long period of time. For example, ducks, ducks, chickens,
The raw feathers of swans and other animals are degreased, washed, and otherwise processed and are widely used for pet feathers, feather brooms, feather beaters, feather feathers, bedding, and clothing. However, in recent years, as the number of highly airtight homes equipped with air-conditioning and heating equipment has increased, feather products stored in closets, top bags, or drawers, especially bedding and clothing, emit strange odors during storage and become unusable. Because of this, there has been a strong demand for the development of methods to prevent this. Normally, raw feathers are washed and thoroughly degreased as described above, washed with water, dehydrated, and dried, but several proposals have been made regarding processing methods and processing agents for improving the quality of feathers. For example,
Publication No. 22087 describes the use of a quaternary ammonium type cationic surfactant as a cleaning agent and antistatic agent consisting of an α-olefin sulfonate, an alkylbenzene sulfonate, and an oxyethylene-based ether type nonionic surfactant. It is described that by treating the raw feathers, dirt can be removed and antistatic properties can be imparted. Also, JP-A-55-
Publication No. 26226 describes a method for cleaning raw feathers and imparting antistatic properties using a cleaning agent consisting of a mixture of α-olefin sulfonate and an oxyethylene alkyl phenol ether type nonionic surfactant and an imidazoline type amphoteric surfactant. A method of processing has been proposed. In addition, although these methods have improved the quality of feather products in terms of preventing static electricity, they are virtually unable to prevent the generation of odor over time, which is a serious defect in feather products. Prior to the drying process, deodorization treatment is performed using long-chain alkyldimethylbenzylammonium salts. However, with such deodorizing treatment, it is not possible to expect a satisfactory long-term effect of suppressing the generation of off-flavors. The inventors of the present invention conducted additional tests on previously known or proposed feather deodorizing treatment agents and treatment methods, and investigated their off-odor suppressing effects, but found that the off-odor suppressing effects lasted for a long period of time and were substantially satisfactory. Up to now, no method or treatment agent has been found for preventing the generation of unpleasant odor. Under these circumstances, the present inventors focused on the fact that deodorizing treatment for feather products is an important issue to be solved at present, and as a result of intensive research into a practically satisfactory feather deodorizing treatment agent, We have discovered an extremely excellent processing agent. That is, the present invention provides a feather deodorizing treatment comprising (A) a quaternary ammonium salt type or alkylpyridinium salt type cationic surfactant and (B) an organic carboxylic acid in a weight ratio of 1:9 to 9:1. provide the agent. The first component (A) used in the treatment agent of the present invention is a quaternary ammonium salt type or alkylpyridinium salt type cationic surfactant. As the quaternary ammonium salt type cationic surfactant, for example, the general formula (In the formula, R ¹ is a C _6-18 long chain alkyl group, and X is a halogen atom.) An alkyltrimethylammonium salt represented by the general formula (In the formula, R ² is a C _8-22 long chain alkyl group, and X is a halogen atom.) An alkyldimethylbenzylammonium salt represented by the general formula (In the formula, R ³ is a C _10-18 long-chain alkyl group, and X is a halogen atom.) Alkyldimethylmethallylammonium salts represented by the general formula (In the formula, R ⁴ is a C _6-12 long chain alkyl group, n = 1-
3.X is a halogen atom. ) can be mentioned. More specifically, the compounds included in the above formula () include n-octyltrimethylammonium halide (Cl, Br), lauryltrimethylammonium halide, myristyltrimethylammonium halide, cetyltrimethylammonium halide, and natural coconut (C _8-18 ), soybean ( _C16-18 ), beef tallow ( _C14-18 ) mixed alkyltrimethylammonium halide, etc. Compounds included in formula () include, for example, lauryldimethylbenzylammonium halide. , myristyldimethylbenzylammonium halide, cetyldimethylbenzylammonium halide, and mixed alkyldimethylbenzylammonium halides such as coconut ( _C8-18) , soybean ( _C16-18 ), beef tallow ( _C14-18 ), etc. Further, examples of the compound of formula () include cetyldimethylmethallylammonium halide, myristyldimethylmethallylammonium halide, etc. Furthermore, examples of the compound of formula () include t-octylphenoxyethoxyethyldimethylbenzylammonium Specific examples include halides, etc.Also, examples of alkylpyridinium salt type cationic surfactants include, for example, the general formula (In the formula, R ⁵ is a C _10-18 alkyl group, R ⁶ is H or
It represents CH ₃ and X is a halogen atom. ) Specific examples thereof include myristylpyridinium halide, cetylpyridinium halide, laurylpyridinium halide, laurylpicolinium halide, and the like. Two or more of these can be used in combination. The halogen atom forming the above salt is commonly found in chlorine, and chloride is advantageously used. In addition, examples of the organic carboxylic acid as the second component (B) used in the treatment agent of the present invention include saturated monocarboxylic acids such as formic acid, acetic acid, and propionic acid; saturated dicarboxylic acids such as oxalic acid and succinic acid; acid, aromatic carboxylic acids such as phthalic acid and salicylic acid, and aliphatic oxycarboxylic acids such as glycolic acid, lactic acid, hydroacrylic acid, malic acid, tartaric acid and citric acid. These organic carboxylic acids may be used alone or
Also, two or more types may be used in combination. Among these, aliphatic oxycarboxylic acids and lower saturated monocarboxylic acids are preferred as component (B). The present invention is a processing agent that combines the surfactant as component (A) and the organic carboxylic acid as component (B),
A new deodorizing treatment agent consisting of component (A):component (B) in a weight range of 1:9 to 9:1 completely prevents the occurrence of off-odor in feather products and has a long-term suppressive effect. This is based on the knowledge of Ingredients (A)
Cationic surfactants are well-known substances that are used as fungicides with strong bactericidal properties, as well as antiseptic and antifungal agents, masking agents, and neutralizing agents. However, a long-term deodorizing effect cannot be obtained, and a satisfactory deodorizing effect cannot be obtained even when the weight range of the combination with component (B) is exceeded. The present invention is a treatment agent that combines a cationic surfactant as component (A) and an organic carboxylic acid that is essentially unrelated to deodorizing properties and belongs to the anionic system, and which contains a specific range of both components. It was quite surprising that the object of the invention was effectively achieved by the combination of amounts. In addition, in the treatment agent of the present invention, by further adding a small amount of commercially available wood vinegar, which is a by-product collected during carbonization of wood, etc., or by replacing a part of component (B), It was also found that excellent deodorizing effects can be obtained. Since the substances included in component (A) and component (B) are substantially water-soluble or self-dispersible, the treatment agent of the present invention can be applied to feather treatment by preparing a solution using water as a medium. It is advantageous and desirable to do so. moreover,
These active ingredients are preferably in an aqueous solution state, so when using a water-dispersible substance as an active ingredient or to improve wettability, for example, polyoxyethylene alkyl ether and other known surfactants are preferably used. It is possible to add a nonionic surfactant, a solubilizing agent such as ethylene glycol or propylene glycol, or a hydratable organic solvent such as methanol, ethanol, isopropanol or acetone. Component (A) and component (B) constituting the treatment agent of the present invention
Preferably, a predetermined amount of each component is added to water to prepare a deodorizing treatment solution containing both components, and the pretreated raw feathers are immersed in this solution, or the solution is brought into contact with the raw feathers by spraying. , the combined components of the present invention are attached and retained on the feather surface in a predetermined weight ratio, but each component is prepared as a separate aqueous solution and contacted separately, and component (A) and component (B) are combined according to the present invention. It can also be attached and retained on the feather surface within a weight ratio range of . Therefore, the feather deodorizing treatment agent of the present invention includes cases where both components are retained in combination after treatment. Further, the processing agent of the present invention usually contains 5 to 90% by weight,
Preferably, it is prepared as an aqueous solution with a concentration of 15 to 60% by weight. It is desirable to complete feather treatment in one operation, but if the concentration of the active ingredients is too low, the amount of combined active ingredients will be insufficient and the treatment will have to be performed multiple times, which is inconvenient. A larger amount than necessary will adhere, resulting in uneconomical results. The combined treatment agent of the present invention is preferably applied in an amount ranging from 0.01 to 5% by weight, preferably from 0.1 to 3% by weight, based on the total weight of the feathers to be treated. The feathers treated with the deodorizing treatment agent of the present invention are
It is provided as a practically excellent product that does not emit any strange odor for an extremely long period of time. This excellent feather deodorizing treatment agent is completely new,
This was discovered as a result of many experiments, and its practical value is extremely high. The present invention will be explained in more detail with reference to Examples below. Examples 1 to 11 and Comparative Examples 1 to 11 5 g of raw feathers of Beijing white duck was POE (=9)
The feathers were soaked in 250 ml of an aqueous solution containing 0.1 g of alkyl ( _C12-15 ether), washed thoroughly, rinsed, and centrifugally dehydrated. The feathers were dried at a temperature of 105°C for 1 hour. ) as alkyl (C ₁₆ ) pyridinium chloride, alkyltrimethylammonium chloride produced from hardened beef tallow, or benzalkonium chloride, and malic acid, tartaric acid, or benzoic acid as component (B), as shown in the table below. A 50% by weight aqueous solution of the mixed components in the weight proportions shown was prepared and applied.The application treatment to the feathers was as follows in the above washing treatment.
This was carried out by immersing the washed feathers in an aqueous solution of the treatment agent or by spraying the aqueous solution of the treatment agent during drying. In all of the above treatments, approximately 0.3% by weight of the treatment agent based on the weight of the raw feathers was adhered to and retained on the feathers. In addition, a treatment agent using wood vinegar as a part of malic acid, a case where component (A) or component (B) was treated alone for comparison, and a treatment agent using phosphoric acid as component (B) and component (A)
Tests were also conducted on processing agents in combination with the above and combination processing agents outside the combination weight range of the present invention, and the results are summarized in the table. For comparative reference, untreated samples are also listed. In a test to examine the deodorizing effect, feathers were stored in a constant temperature and humidity chamber at a temperature of 35°C and relative humidity (RH) of 85%, and the occurrence of off-odors was investigated over time. The criteria for the evaluations (A to E) in the table are as follows: the odor that is a substantial problem as a product is C or lower, and A and B are those that have no effect. A: No abnormal odor B: Almost no abnormal odor C: Slightly abnormal odor D: Abnormal odor E: Strong abnormal odor

[Table] From the above table, it can be clearly understood that the treatment agent of the present invention has extremely excellent effects.
