维生素B是一组结构各异的化合物，是B族维生素的总称。常见的B族维生素包括维生素B1（硫胺）、维生素B2（核黄素）、维生素B3（烟酸）、维生素B5（泛酸）、维生素B6（包括吡哆醇、吡哆醛及吡哆胺）、维生素B7（维生素H）、维生素B9（叶酸）等，这些均为水溶性维生素。目前，拉姆化妆品检测应用较多的B族维生素有维生素B3 和维生素B5，以及维生素B6和维生素B7。

Vitamin B is a group of compounds with different structures, which is a general term for B vitamins. Common B vitamins include vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (including pyridoxine, pyridoxine and pyridoxine), vitamin B7 (vitamin H), vitamin B9 (afolic acid), etc., all of which are water-soluble vitamins. At present, the more widely used B vitamins in Ram cosmetics are vitamin B3 and B5, as well as vitamin B6 and vitamin B7.

拉姆化妆品检测对于维生素B的检测方法主要包括薄层色谱法、高效液相色谱法、气相色谱法、毛细管电泳法、拉曼光谱法、电导滴定法等。

由于化妆品的基质复杂，提取及分离过程烦琐，因而拉姆化妆品检测对于化妆品中维生素B 的检测多采用高效液相色谱法（HPLC）。

拉姆化妆品检测可检测化妆品中5 种维生素（维生素B1、维生素B2、维生素B3、维生素B6和维生素C）；同时拉姆化妆品检测实验室采用HPLC 法测定化妆品中烟酸、烟酰胺、尿囊素和泛醇的含量。

The detection methods of vitamin B in Ram cosmetic detection mainly include thin layer chromatography, high performance liquid chromatography, gas chromatography, capillary electrophoresis, Raman spectroscopy, conductivity titration, etc. 

 Due to the complex matrix of cosmetics and the cumbersome extraction and separation process, Ram Cosmetics uses high performance liquid chromatography (HPLC) for the detection of vitamin B in cosmetics. 

 Ram Cosmetics Detection can detect 5 vitamins in cosmetics (vitamin B1, vitamin B2, vitamin B3, vitamin B6 and vitamin C); at the same time, Ram Cosmetics Testing Laboratory uses HPLC to determine the content of niacin, nicotinamide, allantoin and panthenol in cosmetics.
