The balance of strength with (ethylene oxide chain) is expressed numerically. As the HLB value, the measured value calculated from the emulsification method is used ("Handbook-Cosmetics / Pharmaceutical Materials-" Nikko Chemicals Co., Ltd. (Revised version issued on February 1, 1977) "203.1 HLB by emulsification method" See the "Measured value" column). For the measurement of the measured HLB value, sorbitan monostearate (for example, NIKKOL SS-10 manufactured by Nikko Chemicals Co., Ltd., HLB value 4.7) and polyoxyethylene sorbitan monostearate (for example, Nikko Chemicals Co., Ltd.) are used as standard substances for surfactants. NIKKOL TS-10 manufactured by NIKKOL TS-10, HLB value 14.9) is used in combination. Liquid paraffin is used as the emulsion. Liquid paraffin shall be measured each time if it is considered to fluctuate depending on the type or lot. Liquid paraffin is emulsified with the above two types of surfactants, the optimum ratio of the surfactant is determined, and the required HLB value (HLB value to be emulsified) of the liquid paraffin is determined. The calculation formula is shown in the formula (1).

通常流動パラフィンの所要ＨＬＢ値は、種類及びロットにもよるが１０．１〜１０．３程度である。次に未知の界面活性剤のＨＬＢの測定は、所要ＨＬＢ値を求めた流動パラフィンを用いて測定する。未知の界面活性剤が親水性であればモノステアリン酸ソルビタンと組み合わせ、未知の界面活性剤が疎水性であればモノステアリン酸ポリオキシエチレンソルビタンと組み合わせて、上記流動パラフィンを乳化し、安定性のあるところの最適割合を求め、未知の界面活性剤のＨＬＢ値をｘとして上記数式（１）に当てはめて算出する。

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 is combined with sorbitan monostearate, and if the unknown surfactant is hydrophobic, it is 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).
