Emulsifier Blend for a Required HLB (Griffin)
Proportions of two emulsifiers for a required HLB, or the HLB of a mixture or of an oil phase (Griffin).

Example
- What to work out
- HLB of a mixture of emulsifiers
- Mixture: emulsifiers, one per line: weight, then its HLB
- 3, 8 1, 16
Result: HLB of the mixture: 10.
The tool opens with these values already filled in. Replace them with your own.
What you enter
- What to work out: blend two emulsifiers (blend), HLB of a mixture (mixture), required HLB of an oil phase (oil), estimate from saponification and acid numbers (sap), or from oxyethylene content (eo)
- Blend: required HLB
- Blend: HLB of emulsifier A, from its data sheet
- Blend: HLB of emulsifier B, from its data sheet
- Blend: total emulsifier weight (optional)
- Mixture: emulsifiers, one per line: weight, then its HLB
- Oil phase: oils, one per line: weight, then its required HLB
- Estimate: saponification number of the ester
The other 3 fields
- Estimate: acid number of the fatty acid
- Estimate: weight percent of oxyethylene
- Estimate: weight percent of polyhydric alcohol (optional)
