Triethanolamine Usage Concentration

Regarding the use of Triethanolamine at concentrations exceeding 5%, based on the information available for Triethanolamine 99%, the recommended usage rate is 0.1-2.5%.

It is explicitly stated not to use more than 2.5% because Triethanolamine can cause skin irritation. It should not touch the skin directly and is primarily used in formulations to adjust the pH value within the recommended concentration range.

Exceeding the recommended usage rate, particularly going above 5% as you asked, significantly increases the risk of skin irritation and potential harm to the skin.
