  • Dishwashing liquid soap formula

    Posted by Anonymous on April 30, 2017 at 8:48 pm

    Hi everybody I just joined the group. I m working on finding a good dishwashing liquid soap formula and I ve been suggested this one: labsa, sles, caustic soda, sodium chloride(ofcourse water, perfumes,…). What do you think? Also which one is really the thickening agent,whish one is the real foaming agent,and which one is the real cleaning agent when the foam ‘disappear’. Since I want something economic I may be missing some few chemicals here, I want to stick with the most important. Tanx

    You would be far better using pre-neutralised DDBS as your main detergent. This would obviate the use of dangerous materials (LABSA and NaOH) and make the manufacture a much simpler mixing process.

    Thickening is provided by complex formation of the mixture of NaDDBS, SLES and sodium chloride. Excess NaCl will cause the detergents to precipitate and/or have poor cold stability.

    The real cleaning agent is the NaDDBS. SLES is mainly a foaming agent present to satisfy the user that the product is functioning well.

    You will need a preservative.

    I don’t know where you are located but in many countries it is possible to buy premixed concentrates of dishwashing detergents ready for dilution and finishing with colour and fragrance. This would be the easiest approach for you and will provide a balanced blend in which the foam collapse corresponds with the end of the cleaning power.

    johnb, you are right about using DDBS or concentrates dishwashing detergents.
    but the cost will be high and the final product price will not be competitive.

    nabil, if you take into consideration the costs of manufacture e.g of neutralising the products yourself, mixing of the components, analysis, quality control and other things, the use of a pre-made concentrate where only dilution, addition of perfume and thickening is needed becomes an attractive proposition.

    nabil You have hijacked this thread. Perhaps Remi was happy with the first reply I gave.

    @johnb nabil talks with the local perception of MENA region and trust me in 99% cases it’s about the cost. Using LABSA ain’t no big deal here and that’s why local brands compete strongly with the biggies. I have worked with LABSA and once you know how to do it properly there is no parallel to it IMHO. Since the pre neutralized sodium salt is a bit more expensive the acid and alkali are the choice of many. 
    But I totally agree with you on safety and handling issues, no argument on that whatsoever.
