HLB System Calculator

Calculate Required HLB for your lipid phase and blend emulsifiers to match.

TARGET REQUIRED HLB

Total Oil Phase: %

Calculate your Required HLB first to determine the emulsifier blend.

HIGH HLB EMULSIFIER (Hydrophilic)

LOW HLB EMULSIFIER (Lipophilic)

Required Ratio to reach HLB

Interactive calculation requires JavaScript. To calculate manually:

Required HLB = Σ (Lipid % / Total Lipid %) × Lipid Req. HLB
% High Emulsifier = 100 × (Required HLB - Low Emulsifier HLB) / (High Emulsifier HLB - Low Emulsifier HLB)
% Low Emulsifier = 100 - % High Emulsifier
