Cosmetics HLB Blend Calculator

Compute the required Hydrophile-Lipophile Balance (HLB) of an emulsifier blend from two ingredient percentages and their individual HLB values.

Ingredient 1 amount (%)

Ingredient 1 HLB

Ingredient 2 amount (%)

Ingredient 2 HLB

公式

HLB_blend = Σ (fraction_i × HLB_i). Typical guides: < 4 water-in-oil, 4–6 W/O emulsifier, 7–9 wetting, 10–13 O/W, 13–16 detergent, 16+ solubilizer.

常见问题

Why mix emulsifiers?

Blends of low- and high-HLB surfactants often form more stable emulsions than a single surfactant at the same average HLB because the two molecules pack at the interface more tightly.

Which HLB do I target?

Every oil phase has a "required HLB" determined experimentally. Match the blend HLB to the required HLB of the oil phase for maximum stability.
