Description

  The present invention relates to a liquid detergent composition for textile products. Specifically, the present invention relates to a cleaning composition that has a high effect of suppressing a raw dry odor after washing clothes and the like, and is excellent in the fragrance of the cleaning agent and the storage stability of the scent.

  In recent years, due to the increasing awareness of the environment, so-called concentrated type cleaning agents having higher cleaning component concentrations than conventional cleaning agents have been developed. Concentrated cleaning agents can reduce the size of cleaning agent containers, and are therefore very effective in reducing environmental impacts, such as reducing resin for containers, reducing transportation costs, and reducing waste after use. It is considered.

  In recent years, the awareness of laundry has changed. In the field of laundry detergents, products have been put on the market that appeal to antibacterial effects, such as suppressing the dry odor of clothes after washing and the generation of off-flavors when the laundry is stored for a long time. For example, Patent Document 1 discloses a cleaning composition for clothing that can contain a dry odor or a strange odor after wearing due to sweat or the like by containing antibacterial metal-containing fine particles. In Patent Document 1, the pH of the detergent composition is preferably 7.5 to 12 from the viewpoint of detergency and the like.

  On the other hand, for example, when hydrogen peroxide is blended in a bleaching detergent composition, it is known that a problem may occur in the storage stability of the fragrance. In Patent Document 2, a liquid bleaching detergent containing hydrogen peroxide is converted into a water-in-oil emulsion so that an ester group, an aldehyde group, an acetal group, an unsaturated bond, etc. are contained in the molecule. It is disclosed that even when a fragrance having a structure in which the bond is broken is blended, high stability can be realized in long-term storage. Patent Document 3 discloses that a liquid bleach containing hydrogen peroxide does not cause a change in aroma during long-term storage by using a specific fragrance in combination.

[Component (A): Nonionic surfactant represented by the general formula (1)]
Component (A) is a nonionic surfactant represented by the general formula (1), and preferred examples thereof include those in which p in the general formula (1) is 0. Examples thereof include those represented by the general formula (1a).

_{RO- (C 2 H 4 O)} q / (AO) r H (1a)
[Wherein, R, AO, q and r have the same meaning as described above. ]

  In the compound represented by the general formula (1a), an aliphatic alcohol having 7 to 22 carbon atoms, preferably 8 to 22 carbon atoms, is subjected to addition reaction of ethylene oxide, or ethylene oxide and an alkylene oxide having 3 to 5 carbon atoms. It can be obtained by addition reaction in a random or block manner.

  Further, q in the general formula (1a) is an average addition mole number of ethylene oxide, and is preferably 14 or more, more preferably 16 or more, more preferably 18 or more from the viewpoint of storage stability, solubility, and washing performance. And preferably 27 or less, more preferably 24 or less. r is the average number of moles of alkylene oxide having 3 to 5 carbon atoms. Alkylene oxide may not be added, but it is preferable to add alkylene oxide, and the average number of moles added is preferably 1 or more, more preferably 2 or more, preferably 4 or less, more preferably from the viewpoint of washing performance. Is 3 or less.

  The alkyleneoxy group AO in the general formula (1a) is obtained by addition reaction of an alkylene oxide having 3 to 5 carbon atoms, and the portion bonded by the addition reaction is a structure branched by methyl, ethyl or propyl. It is preferable to have. AO is preferably an alkyleneoxy group having 3 and / or 4 carbon atoms, specifically, trimethyleneoxy group, oxypropane-1,2-diyl group, oxybutane-1,2-diyl group, oxybutane- Examples include 1,3-diyl group, oxybutane-2,3-diyl group, and tetramethyleneoxy group. In particular, the AO group is preferably an oxypropane-1,2-diyl group (hereinafter, the oxypropane-1,2-diyl group may be referred to as a propyleneoxy group or a PO group).

  Particularly in the present invention, the average added mole number q of ethylene oxide is 16 to 27, more preferably 17 to 24, particularly 18 to 22, the AO group is a propyleneoxy group, and the average added mole number r of propylene oxide is 1. It is excellent in the adsorptivity to the fiber of the cationic surfactant of component (C) not only at low-temperature storage stability and washing | cleaning performance but using the compound which is -4, and also 2-4, especially 2-3 This is preferable from the viewpoint of obtaining a liquid detergent composition.

  By increasing the number of added moles of ethyleneoxy groups (hereinafter sometimes referred to as EO groups) more than nonionic surfactants conventionally used in liquid detergent compositions for textiles, The ability of the component (C) cationic surfactant to adsorb to the fiber can be enhanced, and an excellent deodorizing effect due to sufficient antibacterial properties can be exhibited. In addition, it is preferable that the AO group in the component (A) is included for detergency. Since EO groups generally exhibit hydrophilicity, increasing the number of moles added of EO groups tends to disperse in water rather than the interface such as the fiber surface and tends to make it difficult to obtain sufficient detergency. On the other hand, when the added mole number of EO group is small, it becomes difficult to dissolve in water. The present inventors have surprisingly found that even when the number of added EO groups is increased, the detergency can be secured by using (C) a cationic surfactant together. It has been found that a better detergency can be obtained by having an AO group. Further, the present inventors have found that the non-ionic surfactants used in the past cannot be sufficiently deodorized even when combined with a cationic surfactant, because of the ethyleneoxy group of the nonionic surfactant. It was found that the number of added moles was involved. Since the component (A) used in the present invention can sufficiently exhibit the antibacterial properties of the cationic surfactant, a liquid detergent composition having an excellent deodorizing effect on textiles can be obtained.

  In the general formula (1a), “/” means that the relationship between the EO group and the AO group may be either a random bond or a block bond, and may be any of the following, for example. The r AOs may be divided as a plurality of block bodies.
