Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dry cleaning detergent that has hygienic processability such as antibacterial and deodorizing properties in addition to cleaning, anti-contamination, and soft antistatic properties. . .

[Prior Art] The conventional trend in technological development for this application was initially to solubilize water and improve the removability of stains that are difficult to remove by dry cleaning.

Subsequently, progress has been made in the direction of providing a combination of properties such as cleaning and imparting finishing properties such as flexibility and antistatic properties to the items to be washed, but even now we have not moved beyond this stage.

However, if we take a serious look at the quality issues of dry cleaning, we find that it is not always perfect in terms of hygiene, such as bacteria, mold, and odors. As for technical measures in this area, there is a track record in West Germany where products containing Irgasan D P-300 (a disinfectant manufactured by Ciba Geigy) were sold, and in Japan, benzalkonium Although the use of salt has been reported, there are various problems and there is almost no actual use of it. This is because, in addition to cost issues, there are still unresolved problems such as skin damage, discoloration, decomposition during distillation, metal corrosion, odor generation, and pollution.

[Problem to be solved by the invention]

In view of the above circumstances, the present invention has been developed to eliminate problems such as cost, skin damage, discoloration, metal corrosion, and generation of strange odors, and to provide the conventionally required cleanability, prevention of reverse contamination, prevention of static electricity, and flexibility. The purpose of the present invention is to provide an antibacterial and sanitary dry cleaning detergent composition that has the following properties.

When trying to create a composition with such performance, the easiest thing to think about is to incorporate agents used for sanitary processing, such as antibacterial and deodorizing, into products with a proven track record. However, in this case, the added components are not necessarily inexpensive, resulting in increased costs. Furthermore, even if it is possible to impart antibacterial and deodorizing properties by adding such components, it is not always possible to prevent other properties from deteriorating at all. For example, when a phenol compound is used, the pi of the product tends to decrease, and the coloring increases with age. On the other hand, benzalkonium salts have drawbacks such as corrosion of machinery and rust due to their metal corrosive properties, as well as discoloration of items to be washed. In addition, in complex work processes such as cleaning, it is necessary to consider the problems of contamination with other chemicals, filtration, and adsorption, and it is difficult to achieve stable performance with the addition of small amounts of chemicals. .

As a result of intensive research into solving the problems in the prior art as described above, the inventors of the present invention found that, in addition to the performance conventionally required as a dry cleaning detergent, it also has hygienic processing properties such as antibacterial and deodorizing properties. The present invention has been completed by discovering a cleaning agent having the following properties.

That is, the present invention provides a dry cleaning detergent composition characterized in that a dry cleaning solvent contains a cationic surfactant having the following general formula.

In the above formula, R1 represents an alkyl group or an alkenyl group having 8 to 22 carbon atoms, R2 and R3 represent an alkyl group having 1 to 5 carbon atoms, R4 represents an alkylene group having 2 to 4 carbon atoms, and m represents 1 or 2, n represents an integer of 1 to 5, and X represents an alkyl phosphate ion or a polyoxyalkylene alkyl ether phosphate ion represented by the following formula. However, when m is 2, X may be a single residue or a mixture of residues represented by the following general formulas (1) and (2).

In the above formula, R6 and R6 represent a residue of a polyoxyalkylene ether obtained by adding an alkylene oxide to an alkyl or alkenyl group having 1 to 18 carbon atoms, or an aliphatic alcohol having 1 to 18 carbon atoms.

By using a cleaning composition containing this cationic surfactant, such new dry cleaning can be easily performed. In current cleaning systems, in order to obtain sufficient sanitary effects, the proportion of the above-mentioned cationic surfactants in dry cleaning detergent compositions (so-called soaps) must be 1.
Preferably, the concentration is around 0%.

As a dry cleaning solvent, normal perchloroethylene, Freon R-113, petroleum? 81j') and 1,1,1-)lichloroethane can be used.

[Effects of the Invention] By adding the dry cleaning detergent composition (soap) containing the cationic surfactant of the present invention to a dry cleaning solvent, it can meet only the basic required performance as a detergent such as cleaning and prevention of back contamination. Flexibility and flexibility to the items being washed.
It can provide more advanced finishing effects such as antistatic properties, antibacterial properties, and deodorizing properties.
