Description

  The present invention relates to a cleaning composition for clothing.

  Wool / Drymark clothing detergents, so-called light detergents, are used in knitted products, mainly wool sweaters. In recent years, it has come to be widely used in fashionable clothes such as synthetic fiber and cotton cut-and-sew and pants, as well as underwear such as bras and shorts.

  What is regarded as important as a light detergent is the touch and flexibility at the time of wearing, but it also requires a high cleaning performance against sebum dirt. However, clothes such as wool are not easily wetted with water and do not have good penetrability into the interior of fabrics and the like, and therefore tend to have insufficient detergency. Furthermore, touch and flexibility and high detergency are contradictory functions, and it is one of the challenges of light detergents to achieve both.

Concerning the flexibility of the test cloth after drying, in contrast to the test cloth treated in the same manner with a liquid cleaning composition for standard clothing (indicated in the table as standard detergent, the composition is shown in Table 1), Evaluation was performed by five panelists skilled in the standard. The evaluation score was a total of 5 people.
-2 points: The touch and flexibility are remarkably poor compared to the liquid cleaning composition for standard clothing. -1 points: The touch and softness are poor compared to the liquid cleaning composition for standard clothing. The touch and flexibility do not change compared to the liquid cleaning composition for standard clothing. 1 point: The touch and flexibility are better than the liquid cleaning composition for standard clothing. 2 points: Liquid cleaning for standard clothing. Compared with agent composition, feel and flexibility are remarkably good

・ Preparation of artificial dirt cloth To 75 L of ethylene tetrachloride, 1531.2 g of organic dirt having the composition shown below and 240 g of carbon paste having the composition shown below were added and subjected to ultrasonic dispersion for 10 minutes. A 10 cm wide clean cloth (wool muslin (shown in the table as “wool”), gold cloth 2003 cloth (shown in the table as “cotton”)) is soaked and air-dried after contamination to obtain a contaminated fabric. The contaminated cloth was cut into 10 cm × 10 cm and subjected to a cleaning test.

  The composition of organic dirt is 44.8% cottonseed oil, 10.8% cholesterol, 10.8% oleic acid, 7.8% palmitic acid, 2.0% cetyl alcohol, 5.1% solid paraffin, fluid The paraffin is 5.1% (total 86.4%), and the composition of the carbon paste is Asahi Carbon Black 0.2% and cottonseed oil 13.4% (total 13.6%). Here,% is a ratio (mass basis) in the mixture of organic dirt and carbon paste.

-Cleaning performance evaluation 1.333g of liquid cleaning composition of Tables 1-4 was weighed in 1 liter of aqueous solution (4 degree DH), 1000 ml of solution was prepared, and the test was done with the targotometer. The experimental condition is a washing time of 10 minutes. The detergent concentration is 1.333 g / 1 L, the water hardness is 4 ° DH, the water temperature is 20 ° C., and the rinsing is performed by rinsing with running water at 20 ° C. for 5 minutes. The reflectance of the artificial soil cloth after washing was measured (λ = 550 μm), the washing rate was calculated by the following formula, and evaluated according to the following criteria. At this time, out of the nine artificial dirt cloths, two samples with high cleaning rate and two samples with low cleaning rate were excluded, and the average value of the remaining five sheets was evaluated.
Washing rate (%) = (reflectance after washing−reflectance before washing) / (reflectance of raw fabric−reflectivity before washing) × 100

<Recontamination prevention>
A white cotton cloth (gold cloth 2003 cloth) or a wool white cloth (wool muslin) was cut into 10 cm × 10 cm to form a set of five sheets. Carbon black was added to 1 liter of an aqueous solution of the liquid detergent composition shown in Tables 1 to 4, and the test was conducted with a talometer. This was repeated three times for cumulative washing, and the result of the recontamination prevention rate was measured. The experimental condition is a washing time of 10 minutes. The detergent concentration is 1.333 g / 1 L, the water hardness is 4 ° DH, the water temperature is 20 ° C., and the rinsing is performed by rinsing with running water at 20 ° C. for 5 minutes. The anti-recontamination ability was determined by measuring the reflectance at 460 nm of the raw cloth (white cloth) before washing and the contaminated cloth after the test with a self-recording colorimeter (manufactured by Shimadzu Corporation), and obtaining the re-contamination prevention ratio by the following formula.
Recontamination prevention rate (%) = (reflectance after test / reflectance of base fabric) × 100
