Description

  The present invention relates to a laundry detergent.

In the past, as a method of drying the laundry after washing, "outside drying" has been carried out by drying and drying the laundry outside the room, but in recent years, due to concerns about air pollution and changes in lifestyles, It has come to be carried out "room drying" to dry and dry things to be washed.
However, when the object to be washed is dried in the room, there is a problem that it is not possible to simultaneously obtain a soft and voluminous touch that can be obtained by outside drying and a dry touch.
A softener-containing detergent has conventionally been used to impart a soft touch to the material to be washed, and, for example, a detergent product containing a cationic surfactant such as amidoamine or quaternary ammonium salt is marketed. It is done. However, these were insufficient in providing a soft and voluminous touch.
In addition, Patent Document 1 discloses a detergent which contains water-insoluble silicone and cationic cellulose and has enhanced flexibility. However, although the detergent disclosed in Patent Document 1 can enhance the soft and voluminous touch, at the same time, it has a problem that it is difficult to recall a voluminous dry touch because it imparts a moist touch. Furthermore, when a substrate such as water-insoluble silicone or cationic cellulose is added to a liquid detergent, these substrates may be separated in the liquid detergent and the stability of the preparation may be impaired.

By containing the polyoxyethylene fatty acid alkyl ester, the laundry detergent of the present invention is excellent in water solubility and can easily obtain high detergency. When the laundry detergent of the present invention is a liquid detergent, it is difficult to cause a significant increase in viscosity (gelation) even when containing a high concentration of surfactant, and a concentrate having good fluidity is provided. be able to.
Polyoxyethylene fatty acid alkyl ester, in particular MEE, is a nonionic surfactant in which the orientation between molecules is weak in aqueous solution system and micelles are unstable. It is presumed that large amounts can be incorporated into the liquid detergent. It is also presumed that the solubility in water is improved. Furthermore, it is thought that it contributes to good fluidity at high concentrations. Therefore, when the polyoxyethylene fatty acid alkyl ester is introduced into the water in the washing machine tank, the concentration of the polyoxyethylene fatty acid alkyl ester in the washing liquid becomes fast and uniform, and contacts the object to be washed at a predetermined concentration from the initial stage of washing. It can be considered that high detergency can be obtained.

In the polyoxyethylene fatty acid alkyl ester, the narrow ratio indicating the distribution ratio of compounds (ethylene oxide adducts) having different numbers of repeating oxyethylene groups is preferably 20% by mass or more. The upper limit value of the narrow ratio is preferably substantially 80% by mass or less. The narrow ratio is more preferably 20 to 50% by mass, and still more preferably 30 to 45% by mass from the viewpoint of further improving the storage stability and the solubility in water.
The higher the narrow ratio, the easier it is to obtain good detergency. In addition, when the narrow ratio is 20% by mass or more, particularly 30% by mass or more, a detergent for clothing having a small amount of raw material odor derived from the compound (b1) can be easily obtained. This is because the compound (b1) having a high narrow ratio contains less fatty acid alkyl ester as a raw material thereof and an ethylene oxide adduct in which s is 1 or 2. From the viewpoint of obtaining a detergent for clothing having a low raw material odor, the total content of the fatty acid alkyl ester and the ethylene oxide adduct of 1 or 2 is 0 to the total amount of the polyoxyethylene fatty acid alkyl ester. 5 mass% or less is preferable, and 0.2 mass% or less is more preferable.

  The “narrow ratio” of the polyoxyethylene fatty acid alkyl ester is represented by the following formula (S), and indicates the distribution ratio of ethylene oxide adducts having different numbers of repeating oxyethylene groups.

In the above formula (S), m _max represents the repeating number of the oxyethylene group of the ethylene oxide adduct which is most abundant in the ethylene oxide adduct. i represents the number of repetition of the oxyethylene group. Yi represents the proportion (% by mass) of ethylene oxide adducts in which the number of repeating oxyethylene groups is i, present in all ethylene oxide adducts.
The narrow ratio can be controlled, for example, by the method for producing polyoxyethylene fatty acid alkyl ester.

As the component (B), any one type may be used alone, or two or more types may be used in combination.
The content of the component (B) is not particularly limited, but the use of a small amount of detergent per wash can be small, and the advantage of being compact as a detergent product is obtained. It is preferable to blend in concentration. In this case, as the component (B), a secondary alcohol ethoxylate obtained by adding ethylene oxide to a secondary alcohol (for example, Softanol series manufactured by Nippon Shokubai Co., Ltd.) from the viewpoint of a small gelled region and easy incorporation at high concentrations. And MEE are preferably used. In addition, these may be used in combination with a primary alcohol ethoxylate obtained by adding ethylene oxide to a primary alcohol.

By using MEE as the component (B), gelation hardly occurs even when blended at high concentration. In addition, the soft and voluminous touch and the effect of imparting a dry touch can be easily enhanced.

  10-50 mass% is preferable with respect to the total mass of the detergent for clothing, 10-40 mass% is more preferable, and, as for content of (B) component, 15-30 mass% is more preferable. When the content of the component (B) is equal to or more than the above lower limit value, the detergency is easily enhanced. Moreover, if content of (B) component is below the said upper limit, the thickening in the case of setting it as a liquid detergent can be suppressed, and formulation stability will become easier to be improved more.

[Evaluation of recontamination prevention effect]
The laundry detergent of Examples 22 to 26 was used to perform a washing process in which the washing step, the rinsing step and the drying step shown below were repeated three times in this order.

Cleaning process:
The following cotton cloth, polyester (PE) cloth, wet artificial soiled cloth and skin shirt were used as objects to be washed.
Cotton cloth: 5 pieces of 5 cm x 5 cm cotton knitwear (made by Tanigami Store) as a recontamination judgment cloth.
Polyester (PE) cloth: 5 sheets of 5 cm × 5 cm of polyester tropical (made by Tanigami Store) as a recontamination judgment cloth.
Wet artificial contaminating cloth: Contaminated cloth manufactured by Japan Foundation for the Laundry Science (28.3% oleic acid, 15.6% triolein, 12.2% cholesterol oleate, 2.5% liquid paraffin, 2.5% squalene, cholesterol 20 pieces of cloth with a stain of composition of 1.6%, gelatin 7.0%, mud 29.8%, carbon black 0.5% (mass ratio).
Skin shirts: Skin shirts (LL size, manufactured by DVD) are finely cut (about 3 cm × 3 cm).
In a Terg-o-tometer (manufactured by UNITED STATES TESTING Co., Ltd.), 900 mL of 3 ° DH hard water at 25 ° C. was placed, 0.3 g of a detergent for clothing was added thereto, and then the above-described washed object was placed. Thereafter, 3 ° DH hard water was added to adjust the bath ratio to 20 times, and the plate was washed at 120 rpm and 25 ° C. for 10 minutes.

Rinse process:
After washing, the material to be washed was dehydrated for 1 minute, and then 900 mL of 3 ° DH hard water at 25 ° C. was added, and rinsed at 120 rpm for 3 minutes at 25 ° C. This operation (dehydration, rinse) was repeated twice. In the second time, a predetermined amount of softener was added to 900 mL of 3 ° DH hard water at 25 ° C. for rinsing. As a softener, room-dried Soflan (manufactured by Lion Corporation) was used.

Drying process:
After the rinsed material was dewatered for 1 minute, only the recontamination test cloth (cotton cloth) was taken out, sandwiched with filter paper, and dried with an iron.
