    This is a commercial dishwashing liquid. Can you pleaae identify what are the particles or tiny coloured balls trapped in this dishwash liquid? I have seen much litter particles same as these in a face wash gel also. Seems like manufacturer omits this chemical name from product label.Thank you.

    Only for aesthetic appeal, making product looks something special.

    Or they could be gelatin beads.  They dont actually do anything but make the product look unique.

     Can Gelatine beads float like this? Aren’t they heavy enough to precipitate? Besides their sizes are irregular. I will try to take some of them out and will post a closer image.

    Also, will gelatin beads dissolve when using the product?

    Yes, gelatin beads can float like that. Beads can be suspended in a formula using an acrylic polymer like Carbomer or even Xanthan gum. 

    Irregular sizes are not unexpected. When they produce beads like this the process results in particles with a range of sizes.

    You can find more information about gelatin beads here.

    Could also be Cosmospheres (i.e. microcrystalline cellulose plus lactose or mannitol) ;) .

    @Perry I contacted a beads supplier, he told me those beads are cellulose as @Pharma said. The product I posted here is crazy thick like a gel. (Probably around 3000 cp.) I have took some with fingers and rubbed, it tends to be sticky. Does this indicate that they might be using carbomer to achieve this thickness ? 
    My formula contains, Labsa 10%, SLES 20%, edta, phenoxyethanol, perfume, 
    It wold be great help to give me some idea how to achieve enough thickness to be able to suspend those beads. If to use carbomer how much % should I use?

    Thank you all for answering and showing directions.

    Sticky? Could be carbomer but I doubt that for a number of reasons, one of which is the difficulty of using carbomer in a high % of surfactant, and another, being the cost of doing so. Also, the product doesn’t look clear. I suspect it has a gum, or even several gums, possibly with salt thickening to increase the viscosity further.

    I tried carbomer, labsa, capb, makes them cloudy.
