Amodimethicone viscosity for hair conditioning

I am going to purchase Amodimethicone emulsion to use in Shampoo instead of polyquaternium 10. There are different viscosities.

Which Amodimethicone emulsion viscosity is better for hair conditioning in Shampoo? 

Higher or lower viscosity?

  • Probably cyclomethicone!!

  • My Dow rep told me the 3500 cSt was most common
  • Is it pure amodimethicone not in an emulsion? Emulsified versions are usually used in shampoos. Like this one https://www.ulprospector.com/en/eu/PersonalCare/Detail/1021/42597/SilCare-Silicone-SEA
  • @Dr Catherine Pratt, D4, D5 and D6 are not allowed in wash-off products in EU. So market should be taken into account.

    check the emulsifiers; in my experience, amodimethicone is usually dispersed in a cationic emulsion, making it completely useless in shampoo

  • @Bill_Toge, may I ask why being in emulsion makes it useless? I often notice it in commercial products and I feel it adds slip during washing, although I totally understand that anecdotal evidence isn’t an evidence.
  • @ngarayeva001 they have both pure Amodimethicone and emulsions but want to purchase the emulsion for my Shampoo. I currently use pq10.
    They have viscosities from 1000 up to 100000 cst. Unlike dimethicone the price increases when viscosity increases. 
  • @Dr Catherine Pratt i want it to stay in hair
  • @Bill_Toge the emulsion has %30 Amodimethicone and %2 Cetrimonium Chloride. 
    I wat to add it at %1 which becomes %0.3 Amodimethicone and %0.02 Cetrimonium Chloride.
