Verdict
Generally very well-tolerated; non-irritating at typical use levels; often cited as one of the gentlest cationic surfactants; not a sulfate-type surfactant despite the name. Quaternary ammonium salt (IUPAC: docosyltrimethylammonium methyl sulfate) typically derived from rapeseed oil; provides excellent detangling, anti-static effects, and emulsification; widely used in "clean beauty" and COSMOS-eligible formulations; requires a co-emulsifier/stabilizing agent (commonly cetearyl alcohol)
