How does the addition of 1-Dodecanol (C12OH) affect the properties of Akypo® formulations?

Label:chem

Topic
1-Dodecanol (C12OH) is added to Akypo® to enhance its oil-uptake efficiency and to induce structural transitions in the surfactant formulation.
Answer
The addition of C12OH to Akypo® leads to the formation of a lamellar phase at concentrations starting from 4 v/v%. This structural transition results in tighter packing of the surfactant molecules, as evidenced by a decrease in d-spacing and an increase in the correlation length (ξ) with increasing C12OH content. The presence of C12OH significantly enhances the oil-uptake efficiency of the formulation, achieving an oil absorption ratio of 72 wt% in the IKW test.
