  • PQ7 vs PQ10 deposition of amodimethicone micro emulsion

    Posted by Abdullah on May 22, 2024 at 10:21 pm

    In a shampoo with SLES: CAPB 14:2 active surfactants, which polymer would deposit more of small particle size or micro emulsion amodimethicone in hair?

    PQ7 or PQ10 (jr400)

    There was a very nice article from Dow on the topic. PQ-10 has both more charge density and hydrophobicity than PQ-7, that’s why it’s the king of deposition. For microemulsions there was some caviat compared to large particle silicones, but I can’t recall what. Nevertheless, I believe better deposition using PQ-10 would still hold for microemulsions.
