There is a trophy/achievement that requires you too create all items that can be made using either Chem Fluid or Strong Chem Fluid:

1st Place at the Science Fair

Create all items that contain Chem Fluid and Strong Chem Fluid

What is the full list of items that can be created to unlock this?

In addition, I would be interested to know if any of them don't appear it the 'Combine Menu' which so far has been hinting on what items can be made by combining items in my inventory.

According to this guide, there are a total of eight recipes:

There are 8 recipes in RE7 — 4 Chem Fluid combos, and 4 Strong Chem Fluid combos.

Chem Fluid Recipes

• Chem Fluid + Herb = x1 First Aid Med
• Chem Fluid + Gunpowder = x10 Handgun Ammo
• Chem Fluid + Solid Fuel = x100 Burnen Fuel
• Chem Fluid + Supplements = x1 Psychostimulants

Strong Chem Fluid Recipes

• Strong Chem Fluid + Herb = x1 Strong First Aid Med
• Strong Chem Fluid + Gunpowder = x10 Enhanced Handgun Ammo
• Strong Chem Fluid + Solid Fuel = x2 Flame Rounds
• Strong Chem Fluid + Supplements = x2 Neuro Rounds

Basically, the Strong Chem Fluid recipes are the same as the Chem Fluid ones except you substitute in Strong Chem Fluid to make a different item. The guide also seems to suggest that you can make these by combining the items in your inventory (I'm not sure if that's what you mean by the crafting menu - I don't own the game... yet). It also lists some of the locations where you can find some of the materials.

All chemical fluid recipes appear in the menu, however, there are recipes that do not appear in the combine menu, such as 10 handgun ammo and 1 gunpowder, yielding 5 enhanced handgun ammo.
