  • Help for the formulation of my dishwashing.

    Posted by PacificBlueParrotlet on May 15, 2024 at 12:44 pm

    Hello, everyone! I am trying to make a dishwashing liquid that has a quality grease removing capability, rich foaming potential and anti-bacterial but with great scent. I want to add some fragrance compounds and solvents but I am not really sure if they should be mixed all together with the fragrance oil prior, or should these compounds be mixed/added during the making of the dishwashing liquid (especially the Dipropylene glycol and the Triethyl citrate). I am not 100% sure about the proper percentage of the fragrance compounds, all I know is that it is better that they should not exceed to 1%. I am looking forward for your help.

    P.S. I intended to list them chronologically based on what’s first and the last, did I put them in order correctly?

    Water 70.1

    Ethylenediaminetetraacetic acid (EDTA) 0.1


    Sodium laureth sulfate (SLES) 3.0

    Linear alkyl benzene sulphonic acid (LABSA) 7.0

    Triethanolamine 1.0

    Sodium lauryl sulfate (SLS) needles 8.0

    Cocamide diethanolamine (CDEA) 2.0

    Cocamidopropyl betaine (CAPB) 2.0

    Colorant qs

    Fragrance 3.0

    Dipropylene glycol 0.5

    Aldehyde C-10 (Decanal) 0.1

    Triethyl Citrate (TEC) 0.1

    Polyhexamethylene biguanide 20% 1.0

    Sodium xylene sulfonate 2.0

    I wanted to add them, but I am not sure how to or where (is it on the fragrance or the whole mix itself?)

    *Hexyl acetate



    Thank you for reading me! 💖

    Biguanides are cationic and are not compatible with anionic systems.

    Why do you have so much fragrance (1% should be more than enough) and why are you trying to add extra fragrance components? Just choose a fragrance you like and add it as supplied or work with your fragrance supplier to come up with something that better meets your needs.

    Why did you reduce your surfactants so much in the revised version?

    Thank you for confirming that the fragrance should just be 1% 😅 I bought a dishwashing liquid from a local business and I find the fragrance too light, compared with brands like Ajax. I thought adding more fragrance compounds will make a difference. Also with the biguanide 🙁 A seller said that this is good for dishwashing liquid formulation so I thought adding it is an advantage.

    I simply thought that the unrevised version is too wrong. 🤭

    If you want to use a solvent like Dipropylene glycol, you need to add it at a higher dose. I’m not sure trietyl citrate would do anything at such a low level. If you don’t have silubility issues, you can remove your xylene sulfonate since it can impair detergency and viscosity. A chelating agent if especially usefun in dishwashers…and if you want more foam, you could replace either SLS, CAPB or CDEA for an amine oxide. To boost detergency and viscosity, an inorganic salt can be added (if your system doesn’t get turbid).
