Disperse in glycol/glycerin

Hi everyone, 
what does it mean to disperse an ingredient in glycol/glycerin, and add to emulsion <40 degree Celsius. 

Does this mean I mix in glycerin and add to the cool down phase?

    By glycol, I believe you mean propylene glycol. And yes, you mix the ingredient in glycerin or propylene glycol. The ingredient will not be dissolved, it will be dispersed and you will get some kind of slurry (it depends on the quantity of the ingredient you are dispersing or the quantity of glycerin/propylene glycol). 
    Once the dispersion is ready, you add it to your emulsion while stirring it slowly till it is homogenized.
