Flash Points and Safe Manufacturing Practices

Hi All,

I understand what flash points are and their purposes regarding handling and transport generally, but I am looking for some advice on how one scales up a formulation which is heavy in use on a flammable material.

Specifically, I have a lip recipe which uses 57% Isododecane, FP of 45C and I will be incorporating into it some Sunflower wax (6%) with a melt point of 74C.

The other ingredients are Dimethicone with a higher FP at 10%, and some texturizing powders.

I have made small batches but I'm ramping up to a jacketed container that holds about 10 gallons.  Advice on staging the process or what to worry or not worry about?

Bonus question:  I'll be sending the finished product out for a flash point test, but is there any way to mathematically calculate an estimate of where the product will end up?  I might want to pre-tweak the recipe so that I don't have a restricted to ship finished product.

    make sure the electric systems are properly earthed, make sure there's nothing inside the vessel that generates sparks, and keep the lid shut wherever possible (in order to prevent the release of flammable vapour)
    there are more advanced measures that can be taken, but these cover the basics
