How to calculate the hlb

Web29 mei 2024 · HLB is Calculated – HLB = weight % of water loving molecule (Hydrophilic)/5 Let us say Z is a surfactant made of X and Y where X is a water is Hydrophilic Y is Lipophilic Calculate the weight % of Hydrophilic x% = x/ (x+y)*100 HLB = x%/100 Even though HLB helps in choosing the right surfactant or an emulsifier, it is not accurate. WebHere is an example of an HLB value calculation • our product BRIJ ® 98 INCI name : oleth-20 is a 20 mole ethoxylate of oleyl alcohol • we calculate the molecular weight of the 20 moles of ethylene oxide ( one mole ETO =44 ) – 20 x 44 = 880 • we add this number to the molecular weight of the oleyl alcohol – 880+ 270 = 1150 ( the mol. wt of BRIJ 98 )

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.
