Dec 18, 2024| The usage limit standards of Guanidine carbonate vary in different countries and regions. The following are some specific situations:
China
In cosmetics, the use of guanidine carbonate must comply with the relevant safety technical specifications for cosmetics, and there are strict limitations on its usage concentration, etc., to ensure the safety of products under normal usage conditions. In the field of medicine, when it is used as a drug synthesis intermediate, there are also corresponding quality standards and impurity limit requirements.
United States
For the usage limit of guanidine carbonate in different products, there is its own set of strict regulations. In drug production, the limit requirements for impurity content and other indicators are not exactly the same as those in China; the usage limits in other fields such as cosmetics also vary depending on the product type and usage, and its regulatory focus and evaluation methods are different from those in other countries and regions.
European Union
The European Union has clear regulations on the use of guanidine carbonate in cosmetics.
