Normally, the required HLB value of liquid paraffin is about 10.1 to 10.3, although it depends on the type and lot. Next, the HLB of the unknown surfactant is measured using liquid paraffin for which the required HLB value has been determined. If the unknown surfactant is hydrophilic, it can be combined with sorbitan monostearate, and if the unknown surfactant is hydrophobic, it can be combined with polyoxyethylene sorbitan monostearate to emulsify the liquid paraffin for stability. The optimum ratio at a certain place is obtained, and the HLB value of an unknown surfactant is set to x and calculated by applying it to the above formula (1).
