CAABABHydrophilic Compatible with waterNissin Chemical Industry Co.,Ltd.加热时（60℃）乙炔二醇（2,4,7,9-四甲基-5-癸炔-4,7-二醇=TMDD）是一种非离子表面活性剂，具有中心乙炔键和对称疏水基团。它是小型低分子量骨架结构，分子结构非常稳定，能从液体中高速定向到界面，快速降低液体表面张力。同时由于其亲水基团小，疏水基团大，具有良好的消泡性能，即使少量添加也能赋予基材性能，因此可以在不损害耐水性的情况下使用。我司正在开发一种新产品，可以更轻松地使用难溶于水的乙炔二醇。什么是乙炔二醇与普通表面活性剂的区别结 构表面张力/接触角起泡性Static静止的Dynamic动态的Chemical Name: 2,4,7,9-Tetramethyl-5-decyne-4,7-diol (TMDD)Physical State: Solid (25℃)化学名：2,4,7,9-四甲基-5-癸炔-4,7-二醇（TMDD）性质：固体（25℃）低的低的小的Hydrophobic疏水基团常温（25℃）Hydrophilic亲水基团Compatible with oil氟、硅、其他高级醇等疏水基团，亲油部分普通表面活性剂亲水基团，溶水部分低的高的大的Hydrophobic疏水基团StructureSurface Tension / Contact AngleFoaming PropertyOLFINEHydrophobicCompatibleHydrophobicCompatiblewith oilwith oilRoom Temperature (25℃)○ Low○ Low○ SmallCH₃CH₃CHCH₃CH₃CH₂C≡CCOHCommon SurfactantsHydrophobicHeated (60℃)HydrophilicCompatible with waterCH₃CH₂CHCH₃OHAcetylene glycol (2,4,7,9-tetrameth-yl-5-decyne-4,7-diol = TMDD) is a non-ion-ic surfactant with acetylene linkage at its center and hydrophobic groups symmetri-cally positioned on both sides. It possess-es a highly stable molecular structure and serves as a compact framework for low-molecular-weight compounds. It rapidly orients from the liquid phase to the interface and quickly reduces surface tension. Moreover, due to its small hydro-philic group and larger hydrophobic group, it exhibits excellent defoaming properties. Additionally, even in small quantities, it imparts desirable performance, allowing for its usage without compromising water resistance. We offer products that make acetylene glycol, which is sparingly solu-ble in water, more easily usable.OLFINE is a surfactant with an ABA structure, where it has two hydrophobic groups for every one hydrophilic group. This is in contrast to typical AB structure surfactants, which have one hydrophobic group for every one hydrophilic group. Due to this unique structure, OLFINE exhibits characteristics such as reduced surface tension and contact angle even in dynamic environments. Additionally, it has low foaming properties.OLFINE是一种ABA结构的表面活性剂，具有两个疏水基团和一个亲水基团。与具有一个亲水基团和一个疏水基团的普通AB结构表面活性剂相比，即便在动态环境中，也具有降低表面张力和接触角、起泡小的特点。Fluorine, silicone, other high-level alcohol-based chemicals, etc.○ Low× High× Large02What is Acetylene Glycol?Differences From Typical Surfactants
