quaternium
some quaterniums such as 80 is antistatic, some are preservatives such as quaternium 15. so they are in conditioning group or preservatives?
quaternium 80 and other conditioning quaterniums act like polyquaterniums? -

Quaternium and Polyquaternium refer to molecules that have a + charged Nitrogen ion. Otherwise the molecules are not related. So just because something is a Quaternium or Polyquaternium doesn’t mean they are going to function similarly. The numbers also don’t mean much of anything except the order in which they were registered.

ok quaterniums are preservatives or conditioners?

@Perry I have read somewhere that the numbering is related to the source as well, is that correct?????????
-
@nasrins - yes, quaterniums can be either. Quaternium 80 is a conditioner. Quaternium 15 is a preservative.
@milliachemist - I haven’t heard that. I’m under the impression (from reading the PCPC guidelines to the INCI dictionary) that the numbers are just order of registration. -
@perry I think numbers in polyquaterniums are about their degree of polimerization…

Thanks Perry, it was rather the case as stated by you.
Cheers
