PQ7 vs PQ10 deposition of amodimethicone micro emulsion
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)

PQ-7

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.

Do you know what was the article name from Dow?
