皮肤癣病为常见疾患之一,向来缺乏良好的治疗剂。十一烯酸(Urdecylenic aci■)疗效的发现,造福人类堪称非浅。194■年Keen■y等氏先发现十一烯酸之制霉菌作用,其钠盐之制霉菌作用较当时应用之丙酸钠为强。次年,氏继报告在各种细菌培养基中十一烯酸钠之杀菌制菌效力较癸酸钠为大。1947年Foley及■氏报告百分之一的十一烯酸制剂杀病原霉菌效力较一般有效脂肪酸制剂为强。

本标准规定了化妆品（膏霜、乳液、化妆水）和洗手液类产品中十一烯酸及其锌盐的气相色谱测定方法。

本标准适用于化妆品（膏霜、乳液、化妆水）和洗手液类产品中十一烯酸及其锌盐的测定。

本方法对十一烯酸及其锌盐的检出限为12 mg/kg(0.0012%)，定量限为40 mg/kg(0.004%)(均以酸计）。

Skin rickets are one of the common diseases and have always lacked good therapeutic agents. The discovery of the efficacy of undecylenic acid (Urdecylenic aci ■) is beneficial to the benefit of mankind. In 194, the first time Keen ■ y was found to have the mold-forming effect of undecylenic acid, and the mold-forming effect of the sodium salt was stronger than that of sodium propionate applied at that time. In the following year, it was reported that the antibacterial and bacteriostatic efficacy of sodium undecylenate in various bacterial culture media was greater than that of sodium citrate. In 1947, Foley and Hershes reported that one percent of the undecylenic acid preparations were more potent than the general effective fatty acid preparations.

This standard specifies the gas chromatographic method for the determination of undecylenic acid and its zinc salt in cosmetics (creams, lotions, lotions) and hand sanitizers.

This standard applies to the determination of undecylenic acid and its zinc salt in cosmetics (creams, lotions, lotions) and hand sanitizers.

The detection limit of this method for undecylenic acid and its zinc salt is 12 mg/kg (0.0012%), and the limit of quantification is 40 mg/kg (0.004%) (all based on acid).
