Chelating agents are compounds with electrophilic groups that can form stable complexes with metal ions. Different types of chelating agents may have different odors, but usually liquid chelating agents should not have a particularly foul odor.
If the liquid chelating agent has a particularly foul odor, it may be due to contamination, decomposition, or degradation, or the use of low-quality raw materials or improper processes in processing and production. In addition, if the chelating agent is excessively diluted or other chemical substances are added, it may also cause it to produce abnormal odors.
Although most liquid chelating agents should not have a particularly foul odor, some specific chelating agents may have a mild and uncomfortable odor. For example, some acidic cleaners and detergents contain EDTA (ethylene diamine tetraacetic acid) chelating agents. Due to the decomposition products of EDTA, which can cause unpleasant odors, these types of cleaners may have a certain odor.
In short, liquid chelating agents PBTC should not have a particularly foul odor. If an abnormal odor occurs, it may indicate that they have been contaminated, degraded, or improperly processed. It is recommended to check whether the chelating agent is normal before use and follow the correct storage and use methods in the product manual.
