Hi Maurice,

Thank you--I'm glad you've joined this discussion   Both apparently.  For

those who have Harry's Cosmeticology 8th edition--under Cleaning of Quaternary

Ammonium Compounds and Cleaning of Polymeric Residue.....page 618--next to the

last paragraph. By reducing the charge density of polyquaternium 10 they were

able to remove 75% of it in one wash with SLS (wool swatches).  So, Maurice,

give us your thoughts on this issue

We've shared this link before, but the section on cationic polymers is

interesting:
