    Posted by Lainee on October 13, 2017 at 5:26 am

    So I’ve come up with an idea to put beads into my hand sanitizer but I don’t know how to deal with these beads. The beads are still hard even after I put them into my hand sanitizer. Should I soak them first in water for about an hour or more before putting them in my hand sanitizer? They should dissolve when I rub them. 

    Also, should I use carbomer for suspending them? Cause they are just settling. Im using HEC.

    The beads are made of Cellulose, Mannitol, Tocopheryl Acetate, Hydroxypropyl Methylcellulose. Thanks !

    Carbomer is best for suspension (even suspends air in water).Try soaking in hydro-alcoholic solution but an hour sounds long so do 15 minute intervals and test for slight softening before adding to sanitizer which I presume is alcohol based.

    @DRBOB@VERDIENT.BIZ yes it is alcohol based. At what ratio of hydro-alcoholic solution?

    63% Ethanol will be a standard dosage, NO HEC and as Dr. Bob says use Carbober instead. Also check with your supplier about the nature of beads, I never had to pre soak them.

    is it likely that these beads are designed to be hard initially and then soften once in the product. This will allow time to fill the product without destroying the bead structure.

    Update: Soaked beads in water-ethanol solution for about 2 hrs. Still hard but it will brittle once rub…. but still hard. Maybe I should soak them longer.

    @Lainee what is the name of the beads?  can you contact the distributor for technical info?  The beads might be hardening due to the alcohol, are they hard in a regular hand soap?
