    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

    @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?

    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.
