With the improvement of living standards, people’s demand for cosmetics is increasing, and its safety has become the focus of attention of consumers and regulatory authorities. Both my country and the European Union have issued corresponding laws and regulations to stipulate the prohibited and restricted substances in cosmetics.
Learn about diethanolamine
Diethanolamine, chemical agent, Chinese name 2,2′-dihydroxydiethylamine, diethanolamine; bishydroxyethylamine; 2,2′-iminobiethanol. Appearance and properties are colorless viscous liquid or crystal. It is alkaline and can absorb gases such as carbon dioxide and hydrogen sulfide in the air. As a raw material for organic synthesis, diethanolamine is widely used in industries such as detergents, cosmetics, pesticides, construction and metals.
Diethanolamine is a prohibited and restricted substance in cosmetics
In the cosmetics industry, alcohol amine products such as diethanolamine are used as pH balance agents, which can be used in beauty care products and washing products.

Alcohol and amine substances are listed as quality control standards.
There are clear regulations on the content of diethanolamine in cosmetics in my country
The 2015 version of “Safety and Technical Specifications for Cosmetics” clearly stipulates that diethanolamine is a prohibited component, and the mass fraction of secondary alkanes (typically diethanolamine) in cosmetics shall not exceed 0.5%, and it is stipulated in other restrictions and requirements Do not use with nitrosation systems.
Detection method of ethanolamine substances in cosmetics
my country’s entry-exit inspection industry standard SN/T 2017—2008 “Determination of monoethanolamine, diethanolamine, and triethanolamine in imported and exported cosmetics” uses gas chromatography-mass spectrometry to detect the content of ethanolamines in cosmetics. The lower limit of determination is 0.05% (mass fraction).
