Description

衣料用液体洗浄剤組成物Liquid detergent composition for clothing
　本発明は、衣料用液体洗浄剤組成物、衣料用液体洗浄剤組成物の製造方法、及び衣料の洗浄方法に関する。 The present invention relates to a liquid detergent composition for clothing, a method for producing a liquid detergent composition for clothing, and a method for cleaning clothing.
背景技術
　衣料等の繊維製品の洗濯方法には、大きく分けて手洗い洗濯と洗濯機洗濯の２種類がある。近年では、アジア地域の洗濯機の普及が増加する傾向にあるが、洗浄力、経済性、文化的背景、洗濯意識などから、手洗い洗濯が広く行われている。手洗い洗濯は、作業者が汚れの落ち具合を確認しながら洗浄できるため、繊維に付着した全体的な汚れだけでなく、部分的な食べこぼし等の汚れを落とす洗浄にも適している。手洗い洗濯では、多くの作業者が、洗浄剤、例えば粉末状や液体状の洗浄剤を水に溶かして得た洗浄液を用いて衣料を洗濯している。 Background technology There are roughly two types of washing methods for textile products such as clothing: hand washing and washing machine washing. In recent years, the spread of washing machines in the Asian region has tended to increase, but hand-washing washing is widely used because of its detergency, economy, cultural background, and washing consciousness. Since the operator can wash the clothes while checking the degree of dirt removal, the hand-washing washing is suitable for washing not only the overall dirt attached to the fibers but also the dirt such as partial food spills. In hand-washing, many workers wash clothes with a cleaning agent, for example, a cleaning liquid obtained by dissolving a powdery or liquid cleaning agent in water.
　液体状の洗浄剤は、洗浄液の調製に用いる他に、繊維製品に直接塗布して用いることもできる。例えば、手洗い洗濯では、作業中に、繊維製品の汚れが目立つ箇所に液体洗浄剤を塗布してもみ洗い等することができる。 The liquid cleaning agent can be used by directly applying it to textile products in addition to being used for preparing the cleaning liquid. For example, in hand-washing, it is possible to wash by applying a liquid detergent to a portion where stains on the textile product are conspicuous during the work.
　特表２０１６－５０３８３３号公報には、液体洗剤であって、その約５重量％～約２０重量％の界面活性剤系を含み、前記界面活性剤系が０．２０～１．７５のアルコキシル化度を有するアルコキシル化アニオン性界面活性剤を含み、前記洗剤は２０℃で約２５００ｍＰａ・ｓ～約６０００ｍＰａ・ｓの注入粘度を有し、中剪断粘度の高剪断粘度に対する比が約２～約１である、液体洗剤が開示されている。当該液体洗剤は、塩化ナトリウム等の電解質を含有できるとされている。 Japanese Patent Application Laid-Open No. 2016-503833 contains a surfactant system of about 5% by weight to about 20% by weight thereof, which is a liquid detergent, and the surfactant system is made into an alkoxyl of 0.20 to 1.75. The detergent contains an alkoxylated anionic surfactant having a degree, and the detergent has an injection viscosity of about 2500 mPa · s to about 6000 mPa · s at 20 ° C., and the ratio of the medium shear viscosity to the high shear viscosity is about 2 to about 1. The liquid detergent is disclosed. It is said that the liquid detergent can contain an electrolyte such as sodium chloride.
　特開２００９－１２０６６４号公報には、エチレンオキシ基を含む所定のエーテル硫酸エステル塩と炭素数３又は４のアルキレンオキシ基を含む所定のエーテル硫酸エステル塩とを混合して得られる界面活性剤組成物が開示されている。当該界面活性剤組成物は、更に、塩化ナトリウム等の無機塩を含有できるとされている。 Japanese Patent Application Laid-Open No. 2009-120664 describes a surfactant composition obtained by mixing a predetermined ether sulfate ester salt containing an ethyleneoxy group and a predetermined ether sulfate ester salt containing an alkyleneoxy group having 3 or 4 carbon atoms. The thing is disclosed. It is said that the surfactant composition can further contain an inorganic salt such as sodium chloride.
　国際公開第２０１７／０６９０１７号には、（Ａ）特定のα－スルホ脂肪酸アルキルエステル塩と、（Ｂ）（Ａ）以外のアニオン界面活性剤と、（Ｃ）ベタイン型両性界面活性剤とを含有する液体洗浄剤が開示されている。当該液体洗浄剤は、更に、硫酸マグネシウム等の水溶性無機塩を含有できるとされている。 International Publication No. 2017/0690117 contains (A) a specific α-sulfo fatty acid alkyl ester salt, (B) an anionic surfactant other than (A), and (C) a betaine-type amphoteric surfactant. The liquid detergent to be used is disclosed. It is said that the liquid detergent can further contain a water-soluble inorganic salt such as magnesium sulfate.
発明の概要

　本発明の衣料用液体洗浄剤組成物は、３０℃におけるせん断速度０．１Ｓ－１の粘度η０．１と３０℃におけるせん断速度１００Ｓ－１の粘度η１００との比であるη０．１／η１００が１．５以上３０以下である。η０．１／η１００は、洗浄力及び溶解性の観点から、好ましくは１．８以上、より好ましくは２以上、そして、好ましくは１５以下、より好ましくは１０以下である。液体洗浄剤が低せん断状態において高粘度であることは、液体洗浄剤に加わる機械力が小さい状態では、高粘度であることを意味し、液体洗浄剤を汚れに塗布した際の、汚れへの密着性の向上による洗浄力の向上につながると考えられる。また、液体洗浄剤が高せん断状態において低粘度であることは、液体洗浄剤に加わる機械力が大きい状態では低粘度であることを意味し、洗濯機などでの濯ぎ時には容易に水に分散し、溶け残りの低減につながると考えられる。本発明の衣料用液体洗浄剤組成物は、η０．１／η１００が所定範囲にあることで、洗浄態様の違いによる機械力の変動に応じた粘度挙動をとることが可能となり、塗布洗浄から浴中洗浄（洗濯機での洗浄）といった種々の洗浄態様において、優れた洗浄力及び溶解性が得られるものと推察される。
　本発明では、粘度η０．１、η１００は、それぞれ、３０℃で、回転式レオメーター（アントンパール社製、型番ＭＣＲ３０２、直径５０ｍｍのコーンプレート使用）を用いて、せん断速度０．１ｓ－１又は１００ｓ－１の条件下で測定する。 The liquid cleaning agent composition for clothing of the present invention has a viscosity η 0.1 having a shear rate of 0.1 S -1 at 30 ° C. and a viscosity η 100 having a shear rate of 100 S -1 at 30 ° C. η 0.1 . / Η 100 is 1.5 or more and 30 or less. From the viewpoint of detergency and solubility, η 0.1 / η 100 is preferably 1.8 or more, more preferably 2 or more, and preferably 15 or less, more preferably 10 or less. The high viscosity of the liquid detergent in a low shear state means that it has a high viscosity when the mechanical force applied to the liquid detergent is small, and when the liquid detergent is applied to the stain, it is applied to the stain. It is considered that the improvement of the adhesiveness leads to the improvement of the detergency. Further, the low viscosity of the liquid detergent in a high shear state means that the viscosity is low in a state where the mechanical force applied to the liquid detergent is large, and it is easily dispersed in water when rinsing with a washing machine or the like. , It is thought that it will lead to the reduction of undissolved residue. The liquid cleaning agent composition for clothing of the present invention has η 0.1 / η 100 in a predetermined range, so that it is possible to take a viscous behavior according to a change in mechanical force due to a difference in cleaning mode, and it is possible to apply and wash. Therefore, it is presumed that excellent detergency and solubility can be obtained in various cleaning modes such as washing in a bath (washing in a washing machine).
In the present invention, the viscosities η 0.1 and η 100 are respectively set at 30 ° C. using a rotary leometer (manufactured by Anton Pearl, model number MCR302 , using a cone plate having a diameter of 50 mm) and a shear rate of 0.1 s-. Measure under the condition of 1 or 100s -1 .

　本発明では、貯蔵弾性率Ｇ’１００と損失弾性率Ｇ''１００は、それぞれ、３０℃で、回転式レオメーター（アントンパール社製、型番ＭＣＲ３０２、直径５０ｍｍのコーンプレート使用）を用いて１００ｒａｄから０．１ｒａｄの範囲で測定し、１００ｒａｄで得られたＧ’、Ｇ’’を貯蔵弾性率Ｇ’１００、損失弾性率Ｇ''１００とする。 In the liquid detergent composition for clothing of the present invention, G'100 / G''100, which is the ratio of the storage elastic modulus G'100 at an angular frequency of 100 rad / s to the loss elastic modulus G''100 , is 1 or more. .. G'100 / G''100 is preferably 1.4 or more, more preferably 1.6 or more, and preferably 10 or less, more preferably 8 or less, from the viewpoint of coating detergency. The liquid detergent composition for clothing of the present invention has a solid property when G'100 / G''100 is within a predetermined range and the time for which mechanical force is applied to the composition is short.
