Quaternium-70
What is Quaternium-70?
Quaternium-70 belongs to the quaternary ammonium compounds, synthetic cationic surfactants created by reacting tertiary amines with fatty alkyl halides to form a positively charged nitrogen headgroup attached to hydrophobic chains. Primarily incorporated into hair care items like conditioners, leave-in treatments, and styling sprays, it works by adsorbing onto the negatively charged surface of hair keratin fibers. This electrostatic attraction neutralizes charge imbalances that cause static cling and tangles, while its lipophilic tails create a thin lubricating layer. The result is lowered friction between hair shafts, easier comb-through, and better alignment for shine. It also imparts a protective hydrophobic barrier against moisture, aiding frizz control in humid environments. Employed at trace levels in mostly rinse-off formulas, it delivers tactile improvements without residue in regular use.
