Dear experts, does anyone have guidance on the production process for Span 80? The products I manufacture become cloudy and opaque after decolorization. Also, I’m wondering how to control the hydroxyl value. Thank you.

A high hydroxyl value is mainly caused by an excess of sorbitol; control the material ratio
