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.

For example, a liquid detergent having a softening effect by combining a nonionic surfactant and a nitrogen-containing compound which is an amine and a salt thereof has been proposed (Patent Document 1). In addition, a combination of a nitrogen-containing compound, a nonionic surfactant and an anionic surfactant, and a polymer has been developed to develop a detergent that exhibits high cleaning performance and recontamination prevention performance without damaging clothing. (Patent Document 2).

  However, with the combination of surfactants of Patent Document 1, flexibility of clothing is recognized, but the cleaning performance of sebum soil and solid particles and the performance of preventing soil re-contamination are still insufficient. Moreover, the liquid detergent of patent document 2 is provided with the clothing damage inhibitory effect and the recontamination prevention property. However, the permeation performance of wool is insufficient, and it cannot be said that the wool feel, flexibility, and anti-recontamination property are fully expressed. Therefore, there has been a demand for a technique for providing flexibility at the time of wearing while having high cleaning performance against sebum dirt and solid particle dirt and a function of preventing recontamination.

  The object of the present invention is to provide an excellent softness-improving effect on clothing, such as wool mark subject clothing, dry mark subject clothing, and cotton clothing. An object of the present invention is to provide a garment cleaning composition having high anti-soil recontamination performance.

The cleaning agent concentration is 1.333 g / 1 L, the water hardness is 4 ° DH, the water temperature is 20 ° C., and the water is rinsed with tap 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
・ 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. Soak a clean cloth (wool muslin) with a width of 10 cm, and air-dry after contamination to obtain a contaminated cloth. 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%) in the mixture of organic dirt and carbon paste.

(Note) The components in the table are as follows.
・ Amine 1: Stearylamidopropyldimethylamine ・ Nonionic surfactant 1: Polyoxyethylene alkyl ether obtained by adding an average of 3 mol of EO to a secondary alcohol having an alkyl group having 10 to 14 carbon atoms ・ Nonionic Surfactant 2: Polyoxyethylene alkyl ether obtained by adding an average of 12 moles of EO to a linear primary alcohol having an alkyl group having 12 carbon atoms. Nonionic surfactant 3: Having an alkyl group having 12 carbon atoms. Polyoxyethylene alkyl ether / copolymer c1: pentene / maleic acid copolymer (pentene / maleic acid molar ratio = 50/50, weight average molecular weight 7000)
Copolymer c2: maleic anhydride-diisobutylene copolymer (maleic anhydride / diisobutylene molar ratio = 50/50, weight average molecular weight 23000)
