聚酸80比聚酸20更有效地显著增强氨酸的溶解性,特别是在低于和临界菌度的度下. 这一发现对于开发局部氨酸配方至关重要.
科学领域:
- 药理学 药理学是指药理学的学科.
- 材料科学 材料科学 材料科学
- 物理化学 物理化学
背景情况:
- 奎思具有宝贵的抗氧化,抗炎,伤口愈合和抗衰老特性,使其适合局部应用.
- 昆塞丁局部使用的一个显著限制是其水溶性差 (25°C时0.01 mg/ml).
- 研究了表面活性剂,以提高奎尔素的水溶性,以改善配方.
研究的目的:
- 为了比较Polysorbate 20 (P20) 和Polysorbate 80 (P80) 在提高氨酸溶解度方面的有效性.
- 评估氨酸在酸盐缓冲体 (pH 4.5±0.2) 中的溶解度,P20和P80的度不同,相对于它们的临界菌根度 (CMC).
主要方法:
- 在最大波长下使用光谱光度法确定奎尔的溶解度.
- 在酸盐缓冲剂 (pH 4.5±0.2) 中进行了溶解性测试,含有或不含P20和P80.
- 表面活性剂度被设置在上面,下面和相应的CMC值.
主要成果:
- 在没有表面活性剂的情况下,奎尔塞丁的溶解度为3.89±0.59 mg/L.
- 聚酸盐20增加了氨酸的溶解度高达2.14倍,但仅在度超过其CMC时.
- 聚酸盐80在所有测试度 (在CMC下方,在CMC上方和CMC以上) 中增加了2.87至3.63倍的奎尔西丁溶解度.
结论:
- 与PolySorbate 20相比,PolySorbate 80在增强氨酸溶解度方面表现出更高的有效性.
- 聚酸80的可溶性增加在所有测试度中是一致的,包括低于其CMC的度.
- 这些发现支持Polysorbate 80的使用,以改善局部Quercetin制剂的配方.

Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
