本発明は液体柔軟剤組成物に関する。 The present invention relates to a liquid softener composition.
一般的に、繊維製品に柔軟性を付与する柔軟剤は、長鎖のアルキルを2つ有する4級アンモニウム塩を主柔軟基剤として含有し、更に非イオン性界面活性剤などの相安定化剤、シリコーンなどの柔軟助剤、香料、エタノール、プロパノール、エチレングリコールなどの溶剤などの成分、及び水を含有する組成物であり、水を分散媒として水中に主成分である長鎖ジアルキル基を有する4級アンモニウム塩を分散させた分散溶液である。 In general, a softening agent for imparting flexibility to a textile product contains a quaternary ammonium salt having two long-chain alkyls as a main softening base, and a phase stabilizer such as a nonionic surfactant. , A composition containing a soft assistant such as silicone, a fragrance, a solvent such as ethanol, propanol and ethylene glycol, and water, and having a long-chain dialkyl group as a main component in water using water as a dispersion medium This is a dispersion solution in which a quaternary ammonium salt is dispersed.
最近の柔軟剤に関して、環境に対する関心の高まりから、輸送に優位なコンパクト化のために少量の使用で十分な柔軟性を有する高濃度柔軟剤の開発が求められている。しかしながら高濃度柔軟剤を製造するにあたり、主成分である長鎖ジアルキル基を有する4級アンモニウム塩の配合量が増加すると、水との相構造を形成し易くなることから、柔軟剤が非常に高粘度化する傾向がある。長鎖ジアルキル基を有する4級アンモニウム塩の配合量を増加させた系では、減粘のために相安定化剤などを用いて流動可能な組成物を調製した場合でも、長期貯蔵や温度変化により増粘や分離が生じる。この解決策として、非イオン性界面活性剤を配合することや、長鎖モノアルキル基を有する4級アンモニウム塩を併用する方法が知られている。また特許文献1には、油相の微粒子化を促進させることにより、低粘度で経時安定性が良好な柔軟剤組成物を連続的に製造が開示されている。また組成物の観点から、特許文献2には長期貯蔵後や凍結回復後に安定な柔軟剤組成物が開示されている。 With respect to recent softening agents, the development of a high-concentration softening agent that has sufficient flexibility with a small amount of use for compactness superior in transportation has been demanded due to increasing interest in the environment. However, when producing a high-concentration softening agent, if the amount of the quaternary ammonium salt having a long-chain dialkyl group, which is the main component, is increased, it becomes easier to form a phase structure with water. There is a tendency to thicken. In a system in which the amount of quaternary ammonium salt having a long-chain dialkyl group is increased, even when a flowable composition is prepared using a phase stabilizer or the like for viscosity reduction, long-term storage or temperature change Thickening or separation occurs. As a solution to this problem, a method in which a nonionic surfactant is blended or a quaternary ammonium salt having a long-chain monoalkyl group is used in combination is known. Patent Document 1 discloses the continuous production of a softener composition having a low viscosity and good stability over time by promoting the atomization of the oil phase. From the viewpoint of the composition, Patent Document 2 discloses a softener composition that is stable after long-term storage or after recovery from freezing.
配合直後から貯蔵にかけて、及び凍結回復時に過度の増粘を示さず、粘度を良好に保つには不十分であり、従来以上にこれら課題を解決できる液体柔軟剤組成物が求められている。 There is a need for a liquid softener composition that does not show excessive thickening immediately after compounding and during storage and freeze recovery, and is insufficient to keep the viscosity good and can solve these problems more than ever.
本発明は、高濃度で柔軟基剤を含有し、より少ない構成成分で、調製直後、貯蔵後、凍結回復後の各粘度の増加を抑制することができる液体柔軟剤組成物を提供する。 The present invention provides a liquid softening agent composition that contains a softening base at a high concentration and that can suppress an increase in each viscosity immediately after preparation, after storage, and after recovery from freezing, with fewer components.
水中への陽イオン性界面活性剤の分散として、従来の組成物では非イオン性界面活性剤が用いられることがあるが、本発明者らは、陽イオン性界面活性剤を高濃度で含有する組成物の場合、初期粘度や凍結回復後の増粘に水溶性の非イオン性界面活性剤が影響を与えていることを見出した。更に本発明者らは、トリアルカノールアミンの脂肪酸エステルから製造される陽イオン性界面活性剤に関し、限定的な脂肪酸分布と、“モノ体、ジ体及びトリ体の限定的な比率”で構成された陽イオン性界面活性剤を用いること、そして塩化カルシウムのような水溶性無機塩化物を特定範囲内で比較的多く含有することで、従来、陽イオン性界面活性剤の分散剤として使用されていた非イオン性界面活性剤を実質的に含まない組成で、初期粘度や凍結回復後の粘度の増加を抑制することが出来ること、またDLVO理論などで言われるような電荷の遮蔽による柔軟剤成分の凝集もなく、低粘度且つハンドリングが容易な状態を保つことを見出し、本発明に至った。 As a dispersion of the cationic surfactant in water, in the conventional composition, a nonionic surfactant may be used, but the present inventors contain a high concentration of the cationic surfactant. In the case of the composition, it was found that a water-soluble nonionic surfactant affects the initial viscosity and the thickening after freezing recovery. Furthermore, the present inventors relate to a cationic surfactant produced from a fatty acid ester of trialkanolamine, which is composed of a limited fatty acid distribution and a “limited ratio of mono-, di- and tri-isomers”. In the past, it was used as a dispersant for cationic surfactants by using a cationic surfactant and containing a relatively large amount of water-soluble inorganic chloride such as calcium chloride within a specific range. In addition, it has a composition that does not contain any nonionic surfactant and can suppress the increase in initial viscosity and viscosity after freeze recovery. As a result, the inventors have found that a state of low viscosity and easy handling can be maintained without agglomeration.

Furthermore, (A) component used for the liquid softening agent composition of this invention is comprised by the specific ratio of (ai) component, (a-ii) component, and (a-iii) component.
組成物の調製にあたっては、(A)成分として、(a−i)成分、(a−ii)成分及び(a−iii)成分を本発明の条件で含有する混合物を用いることが好ましい。例えば、炭素数1以上、3以下、更に炭素数2又は3のヒドロキシアルキル基を有するトリアルカノールアミン、好ましくはトリエタノールアミンと、脂肪酸との脱水エステル化反応又は前記アミンと脂肪酸低級アルコールエステルとのエステル交換反応により、エステルアミンを製造し、続いてアルキル化剤により4級化反応を行うことで調製される反応生成物を(A)成分を含む成分として使用することができる。その際、脂肪酸として炭素数の異なる脂肪酸の混合物〔R1COOH(R1は前記の通り。)の混合物〕又は脂肪酸低級アルコールエステルとして脂肪酸部分の炭素数の異なる脂肪酸低級アルコールエステルの混合物〔R1COOR’(R1は前記の通り。R’は好ましくはメチル基又はエチル基である。)の混合物〕を用いることで、(A)成分の条件を満たす反応生成物を製造することができる。 In preparing the composition, it is preferable to use a mixture containing the components (a-i), (a-ii) and (a-iii) under the conditions of the present invention as the component (A). For example, a trialkanolamine having a hydroxyalkyl group having 1 to 3 carbon atoms, preferably 2 or 3 carbon atoms, preferably triethanolamine, and a dehydration esterification reaction between a fatty acid or the amine and a fatty acid lower alcohol ester. A reaction product prepared by producing an ester amine by a transesterification reaction and subsequently performing a quaternization reaction with an alkylating agent can be used as a component including the component (A). At that time, a mixture of fatty acids having different carbon numbers as fatty acids [mixture of R 1 COOH (R 1 is as described above)] or a mixture of fatty acid lower alcohol esters having different carbon numbers in the fatty acid portion as fatty acid lower alcohol esters [R 1 By using COOR ′ (mixture of R 1 as described above. R ′ is preferably a methyl group or an ethyl group)], a reaction product satisfying the condition of component (A) can be produced.
本発明では、(A)成分についてのR1の規定は、合成時に用いる脂肪酸又は脂肪酸エステルの脂肪酸部分のアルキル基及びアルケニル基の炭素数分布に基づくものであってもよい。前記トリアルカノールアミンと脂肪酸又は脂肪酸低級アルコールエステルとを用いる製法では、反応生成物中の(a−i)成分、(a−ii)成分及び(a−iii)成分の組成は、前記トリアルカノールアミンと脂肪酸又は脂肪酸低級アルコールエステルとの反応比率や反応温度及び反応時間により調整することができる。本発明では、(A)成分を含有する反応生成物を、トリエタノールアミンと脂肪酸とで脱水エステル化反応を行い、続いてジメチル硫酸又はジエチル硫酸により4級化する方法で製造することが好ましい。 In the present invention, the definition of R 1 for the component (A) may be based on the carbon number distribution of the alkyl group and alkenyl group of the fatty acid part of the fatty acid or fatty acid ester used during synthesis.

脂肪酸のカルボニルを除いた炭素数の割合は、ガスクロマトグラフィーを用いて各脂肪酸に相当するピーク面積を算出することで測定することができる。具体的測定方法としては、脂肪酸原料をジアゾメタンやトリメチルシリル化剤を用いてメチルエステル化した後、ガスクロマトグラフィーにて分析する。得られた各脂肪酸由来のピーク面積から各脂肪酸質量を算出し脂肪酸組成を求めることができる。 The ratio of the number of carbon atoms excluding carbonyl of the fatty acid can be measured by calculating the peak area corresponding to each fatty acid using gas chromatography. As a specific measuring method, the fatty acid raw material is methylesterified using diazomethane or a trimethylsilylating agent and then analyzed by gas chromatography. The fatty acid composition can be obtained by calculating the mass of each fatty acid from the obtained peak area derived from each fatty acid.

衣料用液体柔軟剤組成物の30℃での粘度を、初期粘度、凍結回復後、貯蔵後について測定した。ここで、初期粘度は、調製直後の組成物の粘度である。また、凍結回復後の粘度は、一旦、凍結させた後、解凍して液状に戻した組成物についての粘度である。また、貯蔵後の粘度は、20℃で20日貯蔵後の組成物についての粘度である。結果を表1に示す。粘度の測定は、何れも、B型粘度計(東機産業:VISCOMETER TVB-10)を用いて、30℃恒温槽中でサンプル瓶を水に浸した状態で、60rpmで1分間せん断をかけて測定を行った。なお、表1中、粘度の欄の「−」は、層分離を生じたため測定しなかったことを意味する。
<Method for Measuring Viscosity of Softener Composition for Clothing>
The viscosity at 30 ° C. of the liquid softener composition for clothing was measured after initial viscosity, freeze recovery, and after storage. Here, the initial viscosity is the viscosity of the composition immediately after preparation. The viscosity after recovery from freezing is the viscosity of the composition once frozen and then thawed to return to liquid form. The viscosity after storage is the viscosity of the composition after storage at 20 ° C. for 20 days. The results are shown in Table 1. Viscosity is measured with a B-type viscometer (Toki Sangyo: VISCOMETER TVB-10), with the sample bottle immersed in water in a 30 ° C constant temperature bath and sheared at 60 rpm for 1 minute. Measurements were made. In Table 1, “−” in the viscosity column means that measurement was not performed because layer separation occurred.
