This is a laundry detergent but it doesn't clean very effectively.

SLS powder 8%
Decyl Glucoside 10%
Tetrasodium EDTA 1%
pH ~11

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.

Abdullah

@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? 

Abdullah

@Quimico thanks
 what is stpp doing and what should be the final pH? 

PhilGeis

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.
