ALMONDAMIDOPROPYL BETAINE.

Valuable CAS 165586-98-1 / ANTISTATIC, CLEANSING, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - FOAM BOOSTING, VISCOSITY CONTROLLING

An amphoteric surfactant, Almondamidopropyl Betaine provides gentle cleansing while enhancing foam and overall formulation mildness. It is well-suited for sensitive skin due to its low irritancy profile.

Summary

antistatic cleansing surfactant foam boosting viscosity controlling

Science

Mechanism of Action

This betaine-type surfactant reduces water's surface tension, effectively lifting oil and dirt. Its zwitterionic nature helps neutralize harsh anionic surfactants, forming milder mixed micelles to protect the skin barrier.

Stability

Stable across a wide pH range (4.0–9.0); however, it is most stable and skin-compatible in the 4.5–8.0 range.

Synergies

  • Mitigates irritancy of harsher anionic surfactants (e.g., SLS)

Conflicts

  • Strongly acidic conditions (may lose amphoteric character)
  • High concentrations of zinc ricinoleate (can cause precipitation at pH > 8.2)

Sensitization risk Low

The CIR deems it safe for use, up to 3.0% active in leave-on products, provided impurities like DMAPA (<0.01%) and amidoamine (<0.5%) are minimized. A 0.005% concentration was non-sensitizing or irritating in a 103-participant study.
