実施例１
表１に示す組成の各成分をタンブラーブレンダーで混合後、押出機にて溶融混練し、ペレット状の熱可塑性樹脂組成物を得た。これらの組成物を使用し、下記の方法で洗浄試験を行った。結果を表１に示す。
Example 1
After mixing each component of the composition shown in Table 1 with a tumbler blender, it was melt-kneaded with an extruder to obtain a pellet-shaped thermoplastic resin composition. Using these compositions, a cleaning test was conducted by the following method. The results are shown in Table 1.
射出成形機（住友重機械工業社製「ＳＨ１００」；シリンダー温度２３０℃）に、先行使用樹脂としてＡＢＳ樹脂（ダイセルポリマー製セビアンV５５０SF）の黒着色品（カーボンブラック濃度２％）１ｋｇを流した。その後、表１の各組成物を流して黒色が消えるまでの組成物の使用量により洗浄性を評価した。 A black colored product (carbon black concentration: 2%) of ABS resin (Cebian V550SF made by Daicel Polymer) was flowed as an advance use resin through an injection molding machine (“SH100” manufactured by Sumitomo Heavy Industries, Ltd .; cylinder temperature 230 ° C.). Thereafter, each composition shown in Table 1 was allowed to flow and the detergency was evaluated based on the amount of the composition used until the black color disappeared.
実施例と比較例との対比から明らかなとおり、（ｂ）成分としてアニオン界面活性剤と２種のノニオン界面活性剤を併用することで、より洗浄性能が向上されることが確認された。
実施例２と実施例３、４との対比から明らかなとおり、（ｃ）成分として12−ヒドロキシステアリン酸の金属塩（亜鉛塩、アルミニウム塩）を併用することにより、ノニオン界面活性剤量を減少させた場合でも、洗浄性を高めることができた。
As is clear from the comparison between Examples and Comparative Examples, it was confirmed that the washing performance was further improved by using an anionic surfactant and two nonionic surfactants as the component (b).
As is clear from the comparison between Example 2 and Examples 3 and 4, the amount of nonionic surfactant is reduced by using a metal salt (zinc salt, aluminum salt) of 12-hydroxystearic acid as component (c). Even in the case of cleaning, the cleaning property could be improved.
