    Can someone please provide advise on the formulation of a sodium alginate facial mask that can be peeled-off after several minutes after application? What are the pitfalls and where can the sodium alginate be obtained?

    Where to get sodium alginate depends on your region and volumes you plan to purchase- are you making something at home as a hobbyist or for professional use?

    for the hobbyist: https://modernistpantry.com/products/sodium-alginate.html

    for manufacturing: several different options, FMC biopolymer/ kelco used to be large sources , but currently JRS, BASF supply.

    As for the formula, you can find free formulations on the following sites (may or may not have algin):

    People don’t generally give out free custom formulations on this forum, if you are looking to hire a formulator for development :

    Sir-thank you. Can you also provide information on how the actives chemically produce the gel? What amounts of sodium/potassium alginate along with calcium are needed for the best gelling effect? Are there ingredients that enhance or reduce the gelling time and consistency?

        @evchem2 Hi there. I actually tried what you linked but get fish eyes when mixing the powder with water. Any reason why? Is there a specific type of sodium alginate that should be used? Thank you for your insight.

          @Ron_93 I’d have to know more about what you included/ how it was prepared. Did you use a retarder/ extender? Without the extender you may see some lumping from poor dispersion of the alginate, without the retarder you may see lumping from premature gel formation

    Do you or anyone on this thread have experience with mannuronic acid?
