Description
本発明は、衣料用液体洗浄剤組成物に関する。
本願は、2017年12月21日に日本に出願された特願2017−245556号に基づき優先権を主張し、その内容をここに援用する。The present invention relates to a liquid cleaning composition for clothing.
The present application claims priority based on Japanese Patent Application No. 2017-245556 filed in Japan on December 21, 2017, the contents of which are incorporated herein by reference.
界面活性剤濃度が低い液体洗浄剤組成物を増粘する場合、アクリル酸系高分子、又はアニオン界面活性剤と無機塩との組合せが利用される。
しかし、アクリル酸系高分子を利用する場合、塗布洗浄性の低下が懸念される。塗布洗浄性とは、液体洗浄剤組成物を衣類等の被洗物に直接塗布して任意の時間放置し、その後通常の洗濯を行う方法における洗浄性能のことである。加えて、アクリル酸系高分子を利用する場合、低温(5℃以下)時の液体安定性(一定期間保存時の固化、析出、白濁及び分離の生じにくさ)の低下が懸念される。
アニオン界面活性剤と無機塩との組合せにおいて、無機塩として硫酸ナトリウムを利用する場合、低温保存条件で針状や板状の結晶を析出する(低温時の液体安定性が悪い)問題がある。
こうした問題に対し、特許文献1には、特定の溶剤と界面活性剤とを含有する液体洗浄剤組成物が提案されている。特許文献1の液体洗浄剤組成物は、適度な粘度を有し、低温時の液体安定性の改善が図られている。When thickening a liquid detergent composition having a low surfactant concentration, an acrylic acid-based polymer or a combination of an anionic surfactant and an inorganic salt is used.
However, when an acrylic acid-based polymer is used, there is a concern that the coating cleanability may be deteriorated. The coating detergency is the detergency in a method in which a liquid cleaning agent composition is directly applied to an object to be washed such as clothes, left for an arbitrary time, and then ordinary washing is performed. In addition, when an acrylic acid-based polymer is used, there is a concern that the liquid stability at a low temperature (5 ° C. or lower) (difficulty of solidification, precipitation, white turbidity and separation after storage for a certain period of time) may be lowered.
When sodium sulfate is used as the inorganic salt in the combination of the anionic surfactant and the inorganic salt, there is a problem that needle-like or plate-like crystals are precipitated under low-temperature storage conditions (liquid stability at low temperature is poor).
To solve such a problem, Patent Document 1 proposes a liquid cleaning agent composition containing a specific solvent and a surfactant. The liquid cleaning agent composition of Patent Document 1 has an appropriate viscosity, and the liquid stability at a low temperature is improved.
しかしながら、液体洗浄剤組成物には、より低温での液体安定性が求められている。
そこで、本発明は、適度な粘度を有し、低温時の液体安定性により優れる衣料用液体洗浄剤組成物を目的とする。However, the liquid cleaning agent composition is required to have liquid stability at a lower temperature.
Therefore, an object of the present invention is a liquid cleaning agent composition for clothing, which has an appropriate viscosity and is more excellent in liquid stability at a low temperature.
鋭意検討を重ねた結果、本発明者等は、炭酸水素塩とキレート剤とを特定の割合で組み合わせることで、液体洗浄剤組成物の低温時の液体安定性が向上することを見出した。
即ち、本発明は、以下の態様を有する。As a result of repeated diligent studies, the present inventors have found that the liquid stability of the liquid cleaning agent composition at low temperature is improved by combining the bicarbonate and the chelating agent in a specific ratio.
That is, the present invention has the following aspects.

例えば、一般的なアルカリ触媒である水酸化ナトリウムや水酸化カリウム等を用いて、エチレンオキシドやプロピレンオキシドを原料に付加した場合には、v又はwの分布は、比較的広くなる。特公平6−15038号公報に記載のAl3+、Ga3+、In3+、Tl3+、Co3+、Sc3+、La3+、Mn2+等の金属イオンを添加した酸化マグネシウム等の特定のアルコキシル化触媒を用いてエチレンオキシドやプロピレンオキシドを原料に付加した場合には、v又はwの分布は、比較的狭くなる。The distribution of EO or PO in the general formula (b2) varies depending on the reaction method at the time of production.
For example, when ethylene oxide or propylene oxide is added to a raw material using a general alkaline catalyst such as sodium hydroxide or potassium hydroxide, the distribution of v or w becomes relatively wide. A specific alkoxylation catalyst such as magnesium oxide to which metal ions such as Al 3+ , Ga 3+ , In 3+ , Tl 3+ , Co 3+ , Sc 3+ , La 3+ , and Mn 2+ described in JP-A-6-15038 are added. When ethylene oxide or propylene oxide is added to the raw material in use, the distribution of v or w becomes relatively narrow.
一般式(b1)で表されるノニオン界面活性剤(以下、(b1)成分ともいう)は、ナロー率が20質量%以上であることが好ましく、25質量%以上であることがより好ましい。前記ナロー率が高いほど、良好な洗浄力が得られる。また、前記ナロー率が20質量%以上、特に25質量%以上であると、界面活性剤の原料臭気の少ない洗浄剤組成物が得られやすくなる。
(b1)成分を常法により製造した場合、生成物中には、(b1)成分とともに、洗浄力に寄与しない成分、例えば、(b1)成分の原料である脂肪酸エステルや、一般式(b1)で表されるノニオン界面活性剤のsが1又は2であるエチレンオキシド付加体が共存し、ナロー率を低下させる。そのためナロー率が高いと、共存する成分が十分に少なく、洗浄力の低下、原料臭気の問題が生じにくくなる。
一般式(b2)で表されるノニオン界面活性剤(以下、(b2)成分ともいう)の場合も同様である。
前記ナロー率の上限値としては特に限定されないが、実質的には前記ナロー率が80質量%以下であることが好ましい。
前記ナロー率としては、液体安定性と溶解性が向上するため、20質量%以上50質量%以下であることがより好ましく、20質量%以上40質量%以下がさらに好ましい。
ここで、本明細書において「ナロー率」とは、EOの付加モル数が異なるエチレンオキシド付加体の分布の割合を示し、下記の数式(S)で表される。The nonionic surfactant represented by the general formula (b1) (hereinafter, also referred to as the component (b1)) preferably has a narrow ratio of 20% by mass or more, and more preferably 25% by mass or more. The higher the narrow ratio, the better the detergency can be obtained. Further, when the narrow ratio is 20% by mass or more, particularly 25% by mass or more, it becomes easy to obtain a cleaning agent composition having less raw material odor of the surfactant.
When the component (b1) is produced by a conventional method, the product contains the component (b1) and a component that does not contribute to detergency, for example, a fatty acid ester that is a raw material of the component (b1), or the general formula (b1). An ethylene oxide adduct having an s of 1 or 2 in the nonionic surfactant represented by is coexisting to reduce the narrow ratio. Therefore, when the narrow ratio is high, the number of coexisting components is sufficiently small, and the problems of deterioration of detergency and raw material odor are less likely to occur.
The same applies to the nonionic surfactant represented by the general formula (b2) (hereinafter, also referred to as the component (b2)).
The upper limit of the narrow ratio is not particularly limited, but it is practically preferable that the narrow ratio is 80% by mass or less.
The narrow ratio is more preferably 20% by mass or more and 50% by mass or less, and further preferably 20% by mass or more and 40% by mass or less, in order to improve liquid stability and solubility.
Here, in the present specification, the "narrow ratio" indicates the ratio of the distribution of ethylene oxide adducts having different numbers of moles of EO, and is represented by the following mathematical formula (S).
式(S)において、smaxは、全体のエチレンオキシド付加体中に最も多く存在するエチレンオキシド付加体のEOの付加モル数を示す。iはEOの付加モル数を示す。Yiは全体のエチレンオキシド付加体中に存在する、EOの付加モル数がiであるエチレンオキシド付加体の割合(質量%)を示す。In the formula (S), s max indicates the number of moles of EO of the ethylene oxide adduct that is most abundant in the total ethylene oxide adduct. i indicates the number of moles of EO added. Yi indicates the proportion (mass%) of the ethylene oxide adduct in which the number of moles of EO added is i, which is present in the whole ethylene oxide adduct.
前記ナロー率は、例えば、(b1)成分又は(b2)成分の製造方法等によって制御することができる。(b1)成分の製造方法としては、特に限定されるものではないが、例えば、表面改質された複合金属酸化物触媒を用いて、脂肪酸アルキルエステルにエチレンオキシドを付加重合させる方法(特開2000−144179号公報参照)により容易に製造することができる。(b2)成分の製造方法としては、例えば表面改質された複合金属酸化物触媒を用いて、炭素数6〜22のアルコールにエチレンオキシドを付加重合させる方法により製造することができる。
かかる方法に用いられる表面改質された複合金属酸化物触媒の好適なものとしては、具体的には、金属水酸化物等により表面改質された金属イオン(Al3+、Ga3+、In3+、Tl3+、Co3+、Sc3+、La3+、Mn2+等)が添加された酸化マグネシウム等の複合金属酸化物触媒や金属水酸化物及び金属アルコキシドより選ばれる1種以上により表面改質されたハイドロタルサイトの焼成物触媒等が挙げられる。
前記複合金属酸化物触媒を用いた表面改質においては、複合金属酸化物と、金属水酸化物及び金属アルコキシドより選ばれる1種以上とを併用することが好ましい。この場合、複合金属酸化物100質量部に対して、金属水酸化物及び金属アルコキシドより選ばれる1種以上の割合を0.5質量部以上10質量部以下とすることが好ましく、1質量部以上5質量部以下とすることがより好ましい。The narrow ratio can be controlled by, for example, a method for producing the component (b1) or the component (b2). The method for producing the component (b1) is not particularly limited, but for example, a method of addition-polymerizing ethylene oxide to a fatty acid alkyl ester using a surface-modified composite metal oxide catalyst (Japanese Patent Laid-Open No. 2000-). It can be easily manufactured according to (see JP-A-144179). As a method for producing the component (b2), for example, it can be produced by a method of addition-polymerizing ethylene oxide to an alcohol having 6 to 22 carbon atoms using a surface-modified composite metal oxide catalyst.

Hydro modified by one or more selected from composite metal oxide catalysts such as magnesium oxide to which Tl 3+ , Co 3+ , Sc 3+ , La 3+ , Mn 2+, etc. are added, and metal hydroxides and metal alkoxides. Examples thereof include a calcined product catalyst for tarcite.
