  • How much liquid detergent should be used per load in 8kg machine with 3kg cloths?

    Posted by Abdullah on November 22, 2022 at 12:13 pm

    I am working on a liquid laundry detergent product and adjusting all aspects of it.

    In an automatic 8kg laundry machine, if we wash around 3kg clothes per load, how much liquid detergent should be used if the detergent has 8% active surfactant+ 4% STPP + 0.2% CMC and pH 11 and wash water is very hard? 

    On internet they say things like 1 or 2 tablespoon which is not enough.

    Check 

    Critical Micelle Concentration (CMC)

     of each surfactant that you used in formulation then multiply with 4, that minimum concentration your detergent for slightly to moderate dirt on the cloth, or multiply with 6 up to 8 for highly dirty cloth. Don’t forget to reduce active  surfactant availability based on hardness level water do you used

    The problem is i have no idea with how much water it gets diluted during washing process in front door automatic machine. 

    Any idea how to find it out?

    See common technical sheet of wash machine energy rates or water selector level that you used during washing

    See common technical sheet of wash machine energy rates or water selector level that you used during washing

    Couldn’t find this data on technical sheet.

    I cant find water selector level. Where should I look for it?
