Sorry, this has not been edited for accuracy, copy, or clarity, yet.
1. Manufacturers should have material safety data sheets (MSDS) for each formula.
1.1. Many do not.
1.2. Many have badly written ones.
1.3. Many have fake ones which don't match the formula.
2. There's at least one MNC operating here which has good MSDS data. ChemPro. They have everything you need.
3. Manual dish detergents should have zero caustic soda (NaOH) and may mostly be akyl benzyl sulphonates, and other non-aggressive detergents.
4. If you move in the direction of "multipurpose cleaner" you may find more alcohol content.
5. Dishwashing machines typically use a NaOH solution for the cleaning cycle, and a isopropyle acohol solution for the drying cycle.
6. "Degreaser" is usually NaOH.

You may want to pay premium for certified 5. for food safety. Usually 2-5 rm/L.
You can pay a lot less for 6. if you just go to air-con supply shops and buy the chemical that bubbles on coils (NaOH reacts with Al to produce H2). This is down in the RM2/L range.
3. You can get a wide range of options from hypermarkets to (point 2). All are ok, but (2) will be potent and fairly cheap, and guaranteed safe. About RM2/L.

In general, there are a few classes of ingredients:
- soap / detergent
- alkaline reagent (saponifies fat to soap)
- flocking / flocculating agent (turns cloudy liquid to clear by collecting particles together)
- surfactant (gets between things)
--
Aside from all these I recommend you look at chlorine and peroxide bleaches. Many are in solid form, and easy to store.
