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.
