Primary Chemistry:
Tridecyl alcohol
Chemal TDA-3 is a tridecyl alcohol surfactant used as a cleaning, wetting, and emulsifying additive typically used in hard surface cleaners, metal cleaners, and textile finishes. At use rates as low as 0.25%, Chemal TDA-3 provides effective performance in high-temperature systems and generates minimal foam. Compared to other PCC Chemax surfactants in ChemPoint’s portfolio, Chemal TDA-3 delivers the most powerful wetting and surface tension reduction capabilities.
