Unilever patent homogenizes emulsion at <40°c. Why?
Why this patent from Unilever homogenizes the emulsion with 5000rpm at temperature below 40c? <div>
It is a standard conditioner
2% BTAC
4% FA
1% silicone
</div>

What they are doing is adding cooling water at 40°C, and pushing it through the interfase of your emulsion to swell your LGN, which already got thick. I’d have added it at higher T (around 65-60°C), but some formulas get a boost of viscosity and homogenity by mixing at high speed for a few minutes around 40°C.
