What it does

Triethanolamine (TEA) is an amine base. Its most common job is to neutralise carbomer so a runny liquid turns into a clear gel; it also pairs with fatty acids to form emulsifiers in creams and shaving foams. CosIng lists it as buffering, emulsifying and cleansing surfactant.

It is synthetic and affects none of the six checks.
