产品介绍 The Brij O range are primary O/W emulsifiers, particularly suited to emulsifying unsaturated fatty acids. Suitable for the formulation of microemulsion gels as primary emulsifiers or as co-emulsifiers paired with the Crodafos phosphate esters. They are solubilising, dispersing, spreading, wetting and gelling agents. Brij O20 has been found to be an extremely effective solubiliser for lipophilic vitamins and oil soluble actives. It is effective at remarkably low inclusion ratios of between 2:1 and 5:1 depending on the oil. Recommended topical usage levels of 0.5-10%.

长期鼻腔给药。2、吸收促进剂的鼻黏膜毒性 某些黏膜渗透性差的药物.如蛋白多肽类、同时使用吸收促进剂时其吸收效率会大大提高。但吸收促进剂普遍存在黏膜毒性问题。0.3%的牛磺褐霉素钠(STDHF)可使离体人鼻黏膜纤毛运动不可逆的静止。同浓度的聚氧乙烯月挂醚-9(L-9)和去氧胆酸钠(SDC)能迅速引起纤毛运动不可逆的静止,相比之下甘氨胆酸钠(GC)和牛磺胆酸钠(TC)对离体人鼻黏膜纤毛的影响则温和得多。以蛙上腭模型考察促进剂对黏膜纤毛转运能力的影响时发现:1%溶血胆碱磷脂(LPC)、1%L-
