JP5628537B2 - Cleaning composition for clothing - Google Patents

Description

  The present invention relates to a cleaning composition suitable for textile products for clothing such as clothes, sheets, towels, and the like, and more particularly to a cleaning composition used for washing the textile products with water.

  Since washing agents for clothing are required to have high detergency, generally nonionic surfactants and anionic surfactants are widely used. In recent years, however, consumer preferences have diversified, and detergents require not only detergency but also added value such as antibacterial properties and finishes such as flexibility. It is important to efficiently adsorb the cationic surfactant on the fiber in order to develop the above.

  However, in general, cationic surfactants are more efficiently adsorbed on the fibers because they are distributed more in the cleaning solution than on the fibers due to the action of other surfactants formulated to enhance the detergency. It is very difficult to do. Further, when a large amount of a cationic surfactant is blended in order to increase the amount of adsorption, there is a risk that the detergency will be significantly reduced.

  Patent Documents 1 to 5 describe a soft liquid detergent containing a quaternary ammonium salt. Among these, in particular, Patent Document 4 discloses a cleaning agent having an excellent detergency and flexibility containing a polyoxyethylene alkyl ether having 15 to 30 ethyleneoxy groups and a cationic surfactant. Since it is intended for washing, it is considered that a nonionic surfactant having a high addition mole number of ethyleneoxy groups is used to raise the cloud point. Patent Document 5 describes an anionic surfactant, a cationic surfactant, and a nonionic surfactant obtained by adding 5 to 25 mol of an ethyleneoxy group of a branched alcohol. Patent Document 6 discloses a sebum removing agent composition containing a nonionic surfactant, a cationic surfactant and an inorganic salt. The technique is an invention mainly related to prevention of acne by removing sebum from the skin surface. As an application technique thereof, examples include polyoxyethylene lauryl having an average added mole number of ethyleneoxy groups of 20 or 25. An example of blending a precare agent for clothing and a cleaning agent for clothing containing ether is described. Further, Patent Document 7 contains a specific nonionic surfactant, a specific cationic surfactant, and a specific solvent, and has good permeability when applied to clothing even at low temperatures. Excellent liquid detergent compositions are described.

JP-A-11-217585 JP-A-1-132691 Japanese Unexamined Patent Publication No. 62-70498 Japanese Patent Laid-Open No. 61-66796 JP 62-223299 A JP 2000-128757 A JP 2001-187900 A

  In Patent Documents 1 to 7, the cationic surfactant cannot be effectively left on the surface of the fiber product effectively without reducing the detergency, and completely satisfies antibacterial properties and finish properties. It was not a thing. In order to obtain a predetermined effect by combining an ethylene oxide addition type nonionic surfactant with a cationic surfactant as in Patent Document 7, it is necessary to control the distribution of the number of added moles.

  An object of the present invention is to provide a cleaning composition that not only exhibits a high detergency but also efficiently adsorbs a cationic surfactant on a fiber and exhibits high antibacterial properties and flexibility.

  From a new viewpoint, the present inventors have studied a cleaning agent having excellent detergency while effectively leaving a cationic surfactant on the fiber. As a result, surprisingly, a nonionic surfactant having a large number of added moles of ethyleneoxy group, which has been considered to have a poor hydrophilicity and cannot be expected to have a detergency because its hydrophilicity is too strong, When used in combination with a surfactant, the nonionic surfactant is found to have a detergency equivalent to that of a nonionic surfactant having a short ethyleneoxy group and suitable for detergency and exhibiting water in a temperature of 40 ° C. or lower, Further, the present inventors have found that a cationic surfactant can be easily and effectively attached to a fiber, and have achieved the present invention.

This invention is the washing | cleaning agent composition for clothing containing the following (a) component, (b) component, and (c) component, Comprising: Mass ratio of (a) / [(b) + (c)] is 1 It is 10 and the mass ratio of (c) / (b)] is 0.1-10.
(A) Component: Nonionic surfactant represented by the following general formula (1) R ¹ O— (C ₂ H ₄ O) _m H (1)
[Wherein, R ¹ is a linear primary alkyl group having 8 to 22 carbon atoms, m is an average added mole number, and 20 ≦ m ≦ 50. ]
(B) Component: 6 to 22 carbon atoms which may have an ether bond, an ester bond or an amide bond or a phenylene ring in the middle as a group bonded to the nitrogen atom (however, an ether bond, an ester bond or an amide bond or phenylene) A cationic surfactant having one or two alkyl groups or alkenyl groups (excluding the number of carbon atoms in the ring), and the remainder being a hydroxy group having 1 to 3 alkyl groups or benzyl groups And a cationic surfactant (c) component selected from pyridinium-type cationic surfactants having a hydrocarbon group having 6 to 22 carbon atoms bonded to a nitrogen atom: anionic surfactant

  As described above, the inventors of the present invention are sufficient to use such a nonionic surfactant, a cationic surfactant and an anionic surfactant having an average addition mole number of ethyleneoxy groups of 20 or more. It was found that a detergency can be obtained. This is because the hydrophilicity / hydrophobicity of the entire surfactant system is changed by adding a cationic surfactant and an anionic surfactant at a specific ratio to the highly hydrophilic nonionic surfactant. This is considered to be in an appropriate state.

  In addition, since the nonionic surfactant having an average addition mole number of ethyleneoxy group of 25 or more, particularly 30 or more is highly hydrophilic, even when a mixed micelle is formed with a cationic surfactant and an anionic surfactant, When the interaction is relatively weak and the mixed micelles come into contact with the fiber, the cationic surfactant can be easily adsorbed onto the fiber and the nonionic surfactant can be separated. As a result, the cationic surfactant can be efficiently adsorbed on the fiber.

  Generally, when the average added mole number of ethyleneoxy groups of nonionic surfactants increases, the detergency tends to decrease. So far, more than 20 nonionic surfactants are mostly used for detergents for clothing. It never happened. The reason for this was thought to be that the dispersibility in water increased rather than acting on the fibers due to increased hydrophilicity. The present invention brings about an effect that cannot be predicted from such technical common sense. In addition, when a common nonionic surfactant with a low average addition mole number of ethyleneoxy groups is used in combination with a cationic surfactant, the cationic surfactant has sufficient effects such as antibacterial properties and flexibility on textile products. I can't demonstrate it. Nonionic surfactants with an average added mole number of ethyleneoxy groups that can be expected to have a detergency tend to form extremely strong mixed micelles with cationic surfactants, resulting in the presence of cationic surfactants in the cleaning solution. Not only does it become difficult to adsorb on the cloth during the washing process, but also the nonionic surfactant remaining in the rinsing process can be easily washed away from the fiber. Therefore, it is considered difficult to adsorb to fibers.

  The cleaning composition for clothing of the present invention not only has excellent detergency, but also has a high antibacterial property and flexibility, and the cationic surfactant, which is a functional component, is efficiently adsorbed on the laundry fibers. Showing gender.
