Ossamonio 1825

"OSSAMONIO 1825 is an antistatic and conditioning agent composed of 25% stearalkonium chloride" (ULP)
-- Can this replace BTMS in a hair conditioner?
The only actives I have available apart from that, are cetrimonium chloride and Polyquat 7.

  • stearalkonium is a type of benzalkonium

    Benzalkoniums are banned by the FDA in actibacterial soaps
    I wonder if they were banned because they don't reduce bacterial counts much more than washing the hands with soap does, or if it's because it actually has some toxicity.

    The Stearalkonium molecule has an aromatic ring that cetrimonium or behentrimonium don't.
    I wonder how this makes it different, both regarding its conditioning effects and toxicity.

    I believe Cetrimonium chloride is just as good, if not better then behentrimoniums.
    I tried making both leave-on and rinse off conditioners with equivalent amounts of BTMS-50 and Cetrimonium chloride + cetyl alcohol and my customers just couldn't notice any difference in a blind test.

    While CETAC works the same than BTMS, in order to make a superb conditioner, I believe that you just must use some Polyquaternium-10 and amodimethicone.
  • Unfortunately I can't easily obtain Polyquat 10 or amodimethicone.

  • Some say Guar hydroxypropyltrimonium chloride (which is widely available) works almost the same as PQ-10.
    You can order tiny amounts of PQ-10 overseas to make some tests and compare with Guar HPTC.
    You can buy them online and have it shipped to Mexico, or use some online shopping and courier companies. They do all the customs clearance for you.

    As for amodimethicone, you can contact your local DOW chemicals distributor and see if they sell either 8170 (amodimethicone emulsion) or 8087 (pure amodimethicone), or some other amodimethicone.
    Even if they don't, you can often place a special order for it. It comes in 20 or 25 Kg vessels from the factory, so it's not like you have to buy a huge drum.

    Please keep us posted with your test results.

    it should be OK, though it may be less viscous as the alkyl chain is shorter (C18 vs. C22)
    also, stearalkonium chloride is not a kind of benzalkonium chloride; it is strictly aliphatic and does not have any benzene rings in it
