  Polyquaternium-11 - Heat Protectant?

  Posted by Sailor on November 9, 2024 at 8:24 am

  I recently formulated a hair spray with both polyquats 7 & 11 and testing has been great.

  Is there any info out there about thermal/heat protection especially for Polyquat 11?

  @Sailor polyquaternium-11 is quite stable at the higher temperatures of styling implements, but its film structure will usually crack up and cause shedding under heat stress unless plasticized. Your combining with polyquaternium-7 helps with that. On another note: how the heck does that product spray? Neither of these polymers tends to atomize with a Euromist sprayer; they usually just stream out like most polymers. Is this an aerosol then?

    Thanks for the feedback Matt. I just have to see if the combination at least gives desired protection without having to incorporate the usuals aka silicon, PVP or the PQ55/37 etc

    Yes it doesnt atomize. Im thinking to change the consistency. Light cream/gel
