Micellar systems based on syntanols ALM: physicochemical properties and application as adjuvants in herbicide formulations

Abstract

A series of domestic syntanols ALM of the general formula C_nH_(2n+1)O(C₂H₄O)_m and different hydrophilic-lipophilic balance (HLB) were tested to evaluate their potential as adjuvants in herbicide formulations. A comparative analysis of aggregation behavior, surface activity, and solubility of these syntanols and their commercially available foreign analogue Brij®35 was carried out. Using spectrophotometric method, it was shown that syntanol ALM-7 has the greatest solubilizing effect on hydrophobic compounds. Using dandelion leaves as an example, it was demonstrated that, among the tested compounds, syntanols ALM-2 and ALM-7 provided the most efficient transport of the herbicide dicamba to target weeds.
