    关于此产品

    聚甘油,也称polyglycerol,是甘油在碱性催化和真空条件下自身缩合的产物,分子之间通过醚键连接成短链。商品牌号从二聚甘油到十聚甘油不等,为黏稠、色浅、可溶于水的液体或软质固体。

    把它理解为「调高档位的甘油」最为贴切。一个甘油分子带三个羟基;一个十聚甘油带十二个,而骨架质量约为前者的十倍。这提高了分子量、黏度和沸点,同时保持甚至增强了对水的亲和力,因此高聚合度牌号的保湿能力强于甘油,却远不如甘油易挥发,也不像高用量甘油那样发黏。从大约四聚甘油往上,HLB超过15,这正是它本身可用作增溶剂和分散剂的原因——在必须避开环氧乙烷化学的配方中,它可以替代乙氧基化增溶剂和珠光剂。不过,绝大部分产量并非以其本体使用:它是制取聚甘油脂肪酸酯(即E475乳化剂族)和聚甘油蓖麻醇酸酯的骨架。牌号比名称更重要,因为聚合度决定了其余一切,必须在订单中写明。

    用作个人护理中的保湿剂、替代乙氧基化物的增溶剂和分散剂、黏度与密度调节剂、聚甘油酯乳化剂的原料,以及聚氨酯和醇酸树脂的多元醇。

    Bio Green Oleo 供应聚甘油,按聚合度、羟值、色泽、水分和pH值规格执行,250公斤桶装。请说明牌号,因为二聚甘油和十聚甘油的表现相当不同。
