CAPRAMIDOETHYL CAPRAMIDOPROPYLDIMONIUM METHOSULFATE.

Valuable / ANTIMICROBIAL, ANTISTATIC, CLEANSING, DEODORANT, HAIR CONDITIONING, SURFACTANT - CLEANSING

A multifunctional quaternary ammonium compound that serves as a sophisticated conditioning agent and antimicrobial stabilizer. It provides a unique cationic film-forming capability that enhances skin feel while actively neutralizing odor-causing bacteria in precision personal care formulations.

Antimicrobial agent Antistatic agent Conditioning agent Deodorant active Surfactant

Science

This molecule operates through a permanent positive electrical charge, which creates an electrostatic attraction to the naturally negative charge of the skin and hair. Upon contact, it forms a weightless, anti-static protective layer that conditions the surface; simultaneously, its cationic structure disrupts the lipid membranes of microorganisms, causing targeted cell expiration without harsh chemical reactions.

Stability

Maintains structural integrity across a broad pH spectrum (2.0–11.0), but exhibits peak performance and compatibility in slightly acidic environments typical of healthy skin.

Synergies

  • Isosorbide Caprylate/Caprate
  • Cationic conditioning agents
  • Non-ionic surfactants

Conflicts

  • Anionic surfactants like SLS/SLES
  • Anionic rheology modifiers like Carbomer
  • Hyaluronic acid (high molecular weight)
