Diethylene Glycol is a chemical compound with reduced poisoning. After getting in the human body, as a result of its fast metabolism and no obvious accumulation, no proof of carcinogenicity, teratogenicity and mutagenicity has actually been found up until now, but high-dose intake will certainly damage the kidneys. This basic material is a prohibited material in China, yet it may be inevitably created or generated as a safety and security threat substance throughout the raw materials, product packaging products, manufacturing, transport as well as storage of cosmetics. As a result, the detection of diethylene glycol in cosmetics has always been A more crucial examination item.
But until now, there is no ideal, exact and independent discovery technique. Normally, describe the “Physical and also Chemical Examination Method 2.20 Diethylene glycol” in the “Cosmetic Safety Technical Specs” (2015 edition), which is suitable for the decision of the diethylene glycol content in the cosmetic raw material propylene glycol. For the content of diethylene glycol in other raw materials, the examination outcomes are not precise. Or describe the “GB/T 21842-2008 Decision of diethylene glycol in tooth paste” method applied on December 1, 2008, to conduct confirmation tests on diethylene glycol in cleansing cosmetics, treatment cosmetics, as well as beauty/modification cosmetics. The speculative outcomes show that this criterion method can be utilized for the decision of diethylene glycol in cosmetics.
The brand-new recommended market standard “QB/T 5411-2019 Decision of the outlawed substance diethylene glycol in cosmetics by gas chromatography” was released on December 2, 2019, and will be implemented on April 1, 2020.
This basic specifies the gas chromatography-hydrogen fire ionization detector approach for the decision of Diethylene Glycol, a forbidden compound in cosmetics, and applies to the decision of Diethylene Glycol in cream, water, emulsion, and also gel cosmetics. The detection limit and also quantitation restriction of this criterion: the discovery limit of diethylene glycol in gels and also fluids is 200 mg/kg, and the quantification limit is 500 mg/kg. The detection limit of diethylene glycol in cream as well as cream examples is 200 mg/kg. The limit of detection was 400 mg/kg, as well as the limit of quantitation was 600 mg/kg.
