苯甲醇是一種無色透明的液體,在很早以前苯甲醇就被作為香料使用.隨著科學(xué)技術(shù)的日新月異,苯甲醇的用途越來越廣泛,化妝品工業(yè)中,苯甲醇作為香料和防腐劑使用,但它卻有很強(qiáng)的毒性.大鼠口服LD50為3.19g/kg.由于苯甲醇毒性強(qiáng),所以在某些方面已受到各國(guó)的限制.我國(guó)對(duì)苯甲醇也作了明文規(guī)定,在國(guó)務(wù)院批準(zhǔn)頒布的化妝品衛(wèi)生管理?xiàng)l例及其實(shí)施細(xì)則中規(guī)定,苯甲醇作為限用物質(zhì)使用,含量不得超過1%.

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司建立了一種靈敏、快速的氣相色譜方法 ,測(cè)定化妝品中防腐劑苯甲醇,檢測(cè)低限為 1.0mg kg。在開展一年多來的化妝品標(biāo)簽審核工作中 ,將其應(yīng)用到近千個(gè)實(shí)際樣品的檢測(cè) ,獲得了滿意的結(jié)果。

Determination of preservative benzyl alcohol in cosmetics by capillary column
Capillary column determination of preservative benzyl alcohol in cosmetics Details:

Name: Capillary Column
Fixing fluid: 5% phenyl-dimethyl polysiloxane
Specification: 60m*0.53mm*1.0um
Model: HH-5
Application: Determination of preservative benzyl alcohol in cosmetics Gas chromatography GB/T 24800.11-2009

Test spectrum of preservative benzyl alcohol in cosmetics by capillary column:

Benzyl alcohol is a colorless and transparent liquid. Benzyl alcohol has been used as a fragrance long ago. With the rapid development of science and technology, benzyl alcohol is used more and more widely. In the cosmetics industry, benzyl alcohol is used as a fragrance and preservative. It is used, but it has very strong toxicity. Rat oral LD50 is 3.19g/kg. Because of the strong toxicity of benzyl alcohol, it has been restricted by various countries in some aspects. China has also made explicit regulations on benzyl alcohol. The approved cosmetic hygiene management regulations and its implementation rules stipulate that benzyl alcohol is used as a restricted substance, and the content must not exceed 1%.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established a sensitive and rapid gas chromatography method to determine the preservative benzyl alcohol in cosmetics with a detection limit of 1.0 mg kg. In the cosmetics label review work carried out for more than a year, it has been applied to the testing of nearly a thousand actual samples, and satisfactory results have been obtained.
