  • Comparison of two liquid laundry detergent formulas

    Posted by abdullah on November 28, 2022 at 3:05 am

    This is thw laundry detergent formula that i have made 

    Formula A 

    SLS in powder form 5.5% active 
    Lauryl glucoside 1.2% active 
    CAPB 1.2% active 
    STPP 6% 
    CMC 0.4% 
    pH 11 

    It is water thin liquid

    This is my competitors formula 

    Formula B
    SLES 20% active 
    LABSA 7% 
    SLS powder 0.3% 
    Caustic soda 0.145% 

    This is a this gel like petrolatum 

    Water is extremely hard here. About 700 TDS and higher.

    A company has this formula B and i want to convince  them that formula A is better than formula B and they should purchase that formula. 

    So i want to know all the advantages and disadvantages of these two formulas comparatively so i know first if formula A is better or not than formula B. 2nd to convince tham that how formula A is better than formula B. 

    My question.
    What is the advantages and disadvantages if these two formulas as laundry detergent?

    One advantage of A is that it costs half of B

    @Abdullah Have you test both products using something like EMPA soiled fabrics, to see the performance vs different type of soils? I’d start by doing that.

    No i haven’t. 

    I have just used them, A has little foam and B has very high amount of foam.

    What is EMPA?

    @Abdullah Formula B foams more both for having a higher anionic level (as well as total surfactant level), and for having a mixture of SLES and LABSA. It also probably has better detergency.

    EMPA soiled fabrics are standard soils used by the industry to evaluate the performance of laundry detergents vs different type of soils (https://www.mrpltd.com/html/empa_soiled_fabrics.html).

    As ketchita said, and consider in context. Are these both for machine use?  HE?

    Formula B is very popular here. It is being sold by the name of laundry vaseline. 

    They are both being used for machine and hand wash but not HE as HE machines are not common here. 

    Water is extremely hard. The TDS of water is ≥700.

    Thanks 

    In this coding for example 101, does it mean we should put 90g soil in 1 m2 fabric or 90g detergent in 1 m2 soiled fabric?
