종래, 제지용 유연제로서는, 일반적으로 비이온성 계면활성제계의 유연제 (예를 들면, 특허 문헌 1) 및 양이온성 계면활성제계의 유연제 (예를 들면, 특허 문헌 2, 3)가 알려져 있다.Conventionally, as softeners for papermaking, nonionic surfactant-based softeners (for example, Patent Document 1) and cationic surfactant-based softeners (for example, Patent Documents 2 and 3) are known.
그러나, 비이온성 계면활성제계의 유연제는, 펄프에 대한 정착성이 나쁘다. 이 때문에, 요구되는 성능을 얻기 위해서, 대량의 첨가가 필요하며, 제조 비용 등의 관점에서 문제가 크다.However, nonionic surfactant-based softeners have poor fixation properties to pulp. For this reason, in order to obtain the required performance, a large amount of addition is required, which poses a significant problem from the viewpoint of manufacturing costs and the like.
또, 양이온성 계면활성제계의 유연제는, 펄프에 대한 정착성이 뛰어나지만, 종이의 강도가 저하되기 쉽다는 문제가 있다.In addition, cationic surfactant-based softeners have excellent fixation properties to pulp, but have the problem that the strength of paper tends to decrease.
이들 문제를 해결하는 방법으로서 알킬기를 갖는 비이온성 계면활성제와 양이온성 계면활성제를 병용한 유연제 (특허 문헌 4)가 알려져 있다.As a method of solving these problems, a softener using a combination of a nonionic surfactant having an alkyl group and a cationic surfactant (Patent Document 4) is known.
특허 문헌 4에 개시된 유연제에 의해 처리된 종이는, 높은 유연성과 높은 강도의 양립이라는 점에서 충분하다고는 말할 수 없다.The paper treated with the softener disclosed in Patent Document 4 cannot be said to be sufficient in terms of both high flexibility and high strength.
이러한 상황 하, 본 발명은, 종이에 대해서 높은 유연성과 높은 강도를 부여할 수 있는 제지용 유연제를 제공하는 것을 주요 목적으로 한다. 또, 본 발명은, 종이에 대해서 유연성과 높은 흡수성을 부여할 수 있는 제지용 유연제를 제공하는 것도 목적으로 한다.Under these circumstances, the main purpose of the present invention is to provide a paper softener capable of imparting high flexibility and high strength to paper. Another object of the present invention is to provide a paper softener capable of imparting flexibility and high water absorption to paper.

As a result, it contains at least one of polyoxyalkylene castor oil and polyoxyalkylene hydrogenated castor oil as component A, and a quaternary cationic surfactant as component B, and also contains polyoxyalkylene castor oil and polyoxyalkylene castor oil as component A. It has been discovered that polyoxyalkylene hydrogenated castor oil, a paper softener containing at least a propylene oxide unit, can impart high flexibility and high strength to paper.
또, 본 발명자들은 A성분으로서, 폴리옥시에틸렌 피마자유 및 폴리옥시에틸렌 경화 피마자유 중 적어도 하나와, B성분으로서, 4급 양이온 계면활성제를 포함하며, B성분의 4급 양이온 계면활성제가, 디메틸디알킬암모늄클로라이드, 트리메틸모노알킬암모늄클로라이드 및 이미다졸린환을 갖는 4급 암모늄염으로 이루어진 군으로부터 선택되는 적어도 1종을 포함하고 있는 제지용 유연제는, 종이에 대해서 유연성과 높은 흡수성을 부여할 수 있는 것을 발견하였다.In addition, the present inventors include at least one of polyoxyethylene castor oil and polyoxyethylene hydrogenated castor oil as component A, and a quaternary cationic surfactant as component B, and the quaternary cationic surfactant of component B is dimethyl. A paper softener containing at least one member selected from the group consisting of dialkylammonium chloride, trimethylmonoalkylammonium chloride, and quaternary ammonium salts having an imidazoline ring is capable of imparting flexibility and high absorbency to paper. discovered that
