Kemsurf OPA is an anionic surfactant created through the sulphonation of oleic acid along the double bonds. This distinctive molecule boasts an exceptionally rapid foam break within 30 seconds in high-agitation systems, leading to virtually eliminated foaming. At 25°C, it appears as a clear amber liquid, and its composition includes fatty acid sulphonate and potassium salt.
