Abstract
Description
本発明は、衣料用液体洗浄剤組成物、及び衣料の洗浄方法に関する。 The present invention relates to a liquid detergent composition for clothing and a method for cleaning clothing.
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。 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 entire 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 a textile product in addition to being used for preparing a 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.
特許文献１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。 Patent Document 1 is a liquid detergent containing about 5% by weight to about 20% by weight of a surfactant system, and the surfactant system has an alkoxylation degree of 0.20 to 1.75. A liquid containing a chemical anionic surfactant, wherein the detergent has an injection viscosity of about 2500 mPa · s to about 6000 mPa · s at 20 ° C. and a ratio of medium shear viscosity to high shear viscosity is about 2 to about 1. Detergent is disclosed. It is said that the liquid detergent can contain an electrolyte such as sodium chloride.
特許文献２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。 Patent Document 2 discloses 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. ing. It is said that the surfactant composition can further contain an inorganic salt such as sodium chloride.
特許文献３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。 Patent Document 3 describes a liquid detergent containing (A) a specific α-sulfo fatty acid alkyl ester salt, (B) an anionic surfactant other than (A), and (C) a betaine-type amphoteric surfactant. Is disclosed. It is said that the liquid detergent can further contain a water-soluble inorganic salt such as magnesium sulfate.
手洗い洗濯などに用いる液体洗浄剤組成物では、良好な洗浄力を有することに加え、１つの製剤が、洗浄液の調製と塗布洗浄の両方に使えることが利便性の上では有利である。一般に、液体洗浄剤組成物の粘度を適度に高くすることは、塗布洗浄には望ましいと考えられるが、水と混合して洗浄液を調製する際の分散性、溶解性の低下が懸念される。 In the liquid detergent composition used for hand washing and the like, in addition to having good detergency, it is advantageous in terms of convenience that one formulation can be used for both preparation of a washing liquid and coating washing. In general, it is considered desirable to appropriately increase the viscosity of the liquid detergent composition for coating and cleaning, but there is a concern that the dispersibility and solubility of the liquid detergent composition may be lowered when the cleaning liquid is prepared by mixing with water.
本発明は、塗布洗浄などに適した粘度を有し、洗浄力に優れ、且つ水への分散性、溶解性にも優れた衣料用液体洗浄剤組成物を提供する。 The present invention provides a liquid detergent composition for clothing, which has a viscosity suitable for coating and cleaning, is excellent in detergency, and is also excellent in dispersibility and solubility in water.
