Have a look at some starting formulations for laundry liquids to find out what else is added to laundry liquid formulations. UL Prospector and Stepan (https://www.stepan.com/content/stepan-dot-com/en/products-markets/formulation-finders.html) are good places to start.

I recommend you the following formula;
1 water
2. LABSA 11%
3. caustic soda 1.4%
4. SLES 7%
5. STPP 1%
THICKNER salt up to 2.5%
This is a very stable formula with high foam & good cleaning properties -
what is pH? Be aware - you can’t sell this in the US.

@PhilGeis pH is 11.
Currently it is for own use because it doesn’t have good enough quality to sell it????.Can i ask why cant sell it in US?

Phosphate regs. To control eutrophication of lakes etc., misguided regulations banned phosphates in household products last century.

@PhilGeis thanks.
Any idea why this formula doesn’t clean oil soil very well from clothes?

@Quimico thanks
what is stpp doing and what should be the final pH? -
Sorry Abdullah, I don’t know.
If you haven’t - suggest you subscribe to Happi (Household and personal product industry) trade journal athttps://www.happi.com/issues/2021-09-01/ .
They publish formulas and you can find ’em in Happi archives. -
