Hlb surfaktan
WebSpan 80 memiliki HLB yaitu 4,3 dan Tween memiliki HLB 15. Makin rendah nilai HLB surfaktan makin lipofil surfaktan itu, sedangkan makin tinggi nilai HLB surfaktan, maka makin hidrofil zat itu. Dalam percobaan ini digunakan nomor seri yang sama agar menghasilkan kestabilan emulsi. The hydrophilic–lipophilic balance (HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating percentages of molecular weights for the hydrophilic and lipohilic portions of the surfactant molecule, as described by Griffin in 1949 and 1954. Other methods have been suggested, notably in 1957 by Davies.
