WIPING DETERGENT COMPOSITION FOR TEXTILE PRODUCTS

FIELD OF THE INVENTION

The present invention relates to a wiping detergent composition for textile products and a washing sheet using the detergent composition, and a method for removing a stain attached to a textile product.

BACKGROUND OF THE INVENTION

Clothes after washed become dirty as a stain such as food or the like, sweat or a sebum stain is attached thereto while they are worn. When stains are attached to clothes while they are worn, it is often the case that the clothes are taken off after worn and the clothes after taken off are washed using washing machines. However, if clothes which people are wearing while being out become spotted with a stain such as a food stain or the like, they have to spend their time with the stain remaining attached, and often feel unpleasant. For removing food-derived stains attached to textile products, stain removing agent compositions for textile products have been known.

For example, JP-A 2001-181683 discloses a stain removing agent composition for textile products capable of significantly reducing the frequency of occurrence of a stain residue or a ring stain, the composition containing an organic solvent with a specific boiling point, a lower alcohol and a surfactant. JP-A H11-502888 discloses a dry cleaning and spot removal composition, which can be directly applied to isolated spots and stains on fabrics, containing a polyacrylate emulsifier, an organic cleaning solvent, optionally a detersive surfactant, and water. JP-A 2003-105399 discloses a stain removing method including applying a specific absorbent pad to a fabric when removing a stain on the fabric using a stain removing agent composition containing a water-soluble organic solvent and a surfactant. All these patent literatures use surfactants or organic solvents as stain removing components.

SUMMARY OF THE INVENTION

One of the problems with the aforementioned stain removing agent compositions for textile products is a ring stain. A ring stain refers to a phenomenon in which, when a detergent liquid is used to remove a stain component such as a stain caused by a surfactant attached to a textile product as a washing component, a food stain attached to a textile product or the like, the stain portion on the textile product is pushed out by the edgemost portion of the detergent liquid to be concentrically spread out around the stain portion and shaped into a ring on the textile product. However, existing stain removing agent compositions for textile products are insufficient to solve the aforementioned ring stain problem. The present inventors have found that there has been a problem of the aforementioned ring stain phenomenon causing a stain attached to a textile product to be spread out around the stain portion, thereby causing a light stain to be spread over the textile product to make it appear as if the area of the stain has expanded, even if the degree of soiling of the stain portion attached to the textile product is reduced by wiping the stain with a detergent liquid.

In addition, excellent detergency against stains attached to textile products has been conventionally required of the aforementioned stain removing agent compositions for textile products. Further, when stains attached to textile products are wiped with washing sheets impregnated with detergent compositions, users touch the detergent compositions by hand through the washing sheets impregnated therewith. In this case, the users may have an unpleasant slimy feeling, such as a slimy sensation on their hands, during the use of the washing sheets.

One embodiment of the present invention relates to a wiping detergent composition for textile products capable of, when wiping a stain derived from food or the like attached to a textile product with a detergent liquid, not only reducing the degree of soiling of the stain portion, but also reducing the spread of the stain around the stain portion, a wiping washing sheet for textile products using the detergent composition, and a method for removing a stain attached to a textile product.

In addition, one embodiment of the present invention relates to a wiping detergent composition for textile products capable of reducing a slimy feeling when the detergent composition is touched by hand while maintaining detergency against stains attached to textile products, a wiping washing sheet for textile products using the detergent composition, and a method for removing a stain attached to a textile product.

(c-1): 2-phenoxyethanol (1.2)

(e-1): tris(hydroxymethyl)aminomethane

(e-2): citric acid

(e-3): caustic soda (1 mass % aqueous solution, used as a pH adjuster)

Wiping detergent compositions for textile products listed in Tables 1 and 2 were prepared as follows using the aforementioned formulation components. Component (a1), component (a1′), component (b), component (c) and optional components other than the pH adjuster were put into a 100 mL glass beaker, to which ion exchange water (50° C.) in an amount of 90 mass % of a required amount was added and into which a stirrer piece (made of Teflon®, 3 cm long) was put, and which was sealed with Saran Wrap®, and the contents were stirred for 10 minutes. After stirred for 10 minutes, the contents were transferred to a water bath filled with water at 5° C. and cooled while stirred until the temperature of the contents reached 25° C. Using a pH meter equipped with a glass pH electrode, the pH was adjusted to a predetermined level by adding the pH adjuster. Ion exchange water was added to make the contents 100 mass %. The pH of the final compositions was measured and listed in Tables 1 and 2. A method for measuring pH is as follows. Note that, in Tables 1 and 2, the content of each formulation component is the amount of an active component.

A composite electrode for pH measurement (manufactured by HORIBA, Ltd., glass slide-in sleeve type) was connected to a pH meter (pH/ion meter F-23 manufactured by HORIBA, Ltd.), and the power was turned on. A saturated potassium chloride aqueous solution (3.33 mole/L) was used as an internal solution of the pH electrode. Next, a pH 4.01 standard solution (phthalate standard solution), a pH 6.86 standard solution (neutral phosphate standard solution) and a pH 9.18 standard solution (borate standard solution) were each filled into 100 mL beakers, which were immersed in a thermostatic bath at 25° C. for 30 minutes. Calibration operation was performed in the order of pH 6.86, pH 9.18 and pH 4.01 by immersing the electrode for pH measurement in each of the standard solutions adjusted to the constant temperature for 3 minutes. A sample to be measured was adjusted to 25° C.; the electrode of the pH meter was immersed in the sample; and the pH was measured 1 minute later.

<Washing Test>
(1) Pre-Washing of Test Cloth

Commercially available TC broadcloth (cotton/polyester ratio=65/35, purchased from Senshoku Shizai Kabushikikaisha Tanigashira Shoten) was cut into sheets each with a size of 1 m×1 m, which were prepared as many as a number equivalent to a mass of about 1.5 kg. EMULGEN 108 (polyoxyethylene alkyl ether, manufactured by Kao Corporation) was dissolved in city water in an amount of 500 mg/kg and washing operation was performed three times in an automatic washing machine (manufactured by TOSHIBA CORPORATION, model number: AW-8D3M). The bath ratio was 20 and the water temperature was 15° C. After that, they were rinsed under running water until no bubbles appeared, dried, and then used.

(2) Preparation of Curry-Soiled Cloth

The pre-washed sheets of TC broadcloth were cut into 6 cm×6 cm pieces, three of which were stacked on top of one another, coated with 50 μl of curry (Soot Thai Red Curry, purchased at Kaldi) heated in a thermostatic bath at 50° C. in the shape of a circle with a diameter of 1 cm, and then, left to stand for 20 minutes under the circumstance at 23° C. and 50% RH. The top one of the three stacked pieces was used as a piece of curry-soiled cloth.

(3) Method of Washing Test

A sheet-like spunlace nonwoven fabric (rayon/polypropylene/polyester ratio=80/10/10, basis weight 60 g/m², 150 mm×100 mm) was impregnated with each of the detergent compositions listed in Tables 1 and 2 at an impregnation rate of 350 mass % relative to the mass of the nonwoven fabric to prepare a wet nonwoven fabric. A wiping test was conducted such that the stained surface of the piece of curry-soiled cloth was wiped with the wet nonwoven fabric 50 times. Note that, in the wiping test with the wet nonwoven fabric, washing operation was performed such that, every 10 times the stain attached to the textile product was wiped with one surface of the wet nonwoven fabric making contact therewith, the surface was changed to the other, with which the stain was wiped. After wiped, the piece of curry-soiled cloth was left to stand for 12 hours under the circumstance at 25° C. and 60% RH.

(4) Method for Evaluating Detergency
(4-1) Method for Evaluating Stain Removal Rate

The reflectance of the stained surface of the piece of curry-soiled cloth after left to stand was measured (with NF777 manufactured by NIPPON DENSHOKU INDUSTRIES CO., LTD., range to be measured: a circle with a diameter of 5 mm at the center of the stain). A stain removal rate was calculated by the following formula, and the average value from measurements of three different pieces of curry-soiled cloth is listed in Tables 1 and 2. Note that reflectance (Z value) before wiping is Za, a Z value after wiping is Zb, and a Z value of white cloth is Zo.

Stain removal rate (%)=(Zb−Za)/(Zo−Za)×100

The higher a value of the stain removal rate is, the more excellent detergency is, and those with a stain removal rate of 70% or more are preferable.

(4-2) Method for Evaluating Stain Spreading Rate

Before and after the washing test in (3), the piece of cloth was subjected to image analysis using a scanner (manufactured by SEIKO EPSON CORPORATION, model type: GT-X820). The area of a range in which the stain was attached was determined and compared with the area of the stain before the washing test, and a stain spreading rate was calculated by the following formula. The average value of the stain spreading rates of three different pieces of curry-soiled cloth is listed in Tables 1 and 2.

Stain spreading rate (%)=(area of stain after washing)/(area of initial stain)×100

The smaller a value of the stain spreading rate is, the less a stain is spread out by wiping, and those with a stain spreading rate of 150% or less are preferable.

(c-1): 2-phenoxyethanol (1.2)

<Component (d)>

(d1-1): dimethylpolysiloxane emulsion (active ingredient 15 mass %, DK Q1-1247, manufactured by Dow Corning Toray Co., Ltd.)

(d1-2): silicone (KF-96, 10,000 cs, manufactured by Shin-Etsu Chemical Co., Ltd.)

(d2-1): silica particles (AEROSIL200, manufactured by NIPPON AEROSIL CO., LTD.)

(e-1): tris(hydroxymethyl)aminomethane

(e-2): citric acid

(e-3): caustic soda (1 mass % aqueous solution, used as a pH adjuster)

Detergent compositions listed in Tables 3 and 4 were prepared as follows using the aforementioned formulation components. Component (a2), component (b), component (c), component (d) and optional components other than the pH adjuster were put into a 100 mL glass beaker, to which ion exchange water (50° C.) in an amount of 90 mass % of a required amount was added and into which a stirrer piece (made of Teflon®, 3 cm long) was put, and which was sealed with Saran Wrap®, and the contents were stirred for 10 minutes. After stirred for 10 minutes, the contents were transferred to a water bath filled with water at 5° C. and cooled while stirred until the temperature of the contents reached 25° C. Using a pH meter equipped with a glass pH electrode, the pH was adjusted to a predetermined level by adding the pH adjuster. Ion exchange water was added to make the contents 100 mass %. The pH of the final compositions was measured and listed in Tables 3 and 4. A method for measuring pH is the same as in examination example 1. Note that, in Tables 3 and 4, the content of each formulation component is the amount of an active component.

<Washing Test>
(1) Pre-Washing of Test Cloth

(2) Preparation of Curry-Soiled Cloth

(3) Method of Washing Test

A sheet-like spunlace nonwoven fabric (rayon/polypropylene/polyester ratio=80/10/10, basis weight 60 g/m², 150 mm×100 mm) was impregnated with each of the detergent compositions listed in Tables 3 and 4 at an impregnation rate listed in Table 3 relative to the nonwoven fabric to prepare a wiping washing sheet for textile products. A wiping test was conducted such that the stained surface of the piece of curry-soiled cloth was wiped with the washing sheet 50 times. Note that, in the wiping test with the washing sheet, washing operation was performed such that, every 10 times the stain attached to the textile product was wiped with one surface of the washing sheet making contact therewith, the surface was changed to the other, with which the stain was wiped. After wiped, the piece of curry-soiled cloth was left to stand for 12 hours under the circumstance at 25° C. and 60% RH.

(4) Method for Evaluating Detergency

The reflectance of the stained surface of the piece of curry-soiled cloth after left to stand was measured (with NF777 manufactured by NIPPON DENSHOKU INDUSTRIES CO., LTD., range to be measured: a circle with a diameter of 5 mm at the center of the stain). A stain removal rate was calculated by the following formula, and the average value from measurements of three different pieces of curry-soiled cloth is listed in Tables 3 and 4. Note that reflectance (Z value) before wiping is Za, a Z value after wiping is Zb, and a Z value of white cloth is Zo.

Stain removal rate (%)=(Zb−Za)/(Zo−Za)×100

The higher a value of the stain removal rate is, the more excellent detergency is, and those with a stain removal rate of 70% or more are preferable.

(5) Method for Evaluating Sliminess

Each wiping washing sheet for textile products prepared was picked up with a thumb and forefinger, and the fingers were shifted left and right 10 times to rub the washing sheet. The degrees of sliminess of the thumb and forefinger immediately after and 10 seconds after releasing the sheet were scored according to the following criteria to evaluate the sliminess. Evaluations were made by three persons, and the average value of the three persons' evaluation scores is listed in Tables 3 and 4. The smaller the evaluation score is, the further the sliminess can be reduced.

Evaluation Criteria (Score)

5: sliminess was strongly felt both immediately thereafter and 10 seconds later

4: sliminess was strongly felt immediately thereafter and sliminess was slightly felt 10 seconds later

3: sliminess was slightly felt immediately thereafter and sliminess was also slightly felt 10 seconds later

2: sliminess was slightly felt immediately thereafter and sliminess was not felt at all 10 seconds later

1: sliminess was not felt at all immediately thereafter and since then
