LAURAMINE.

Valuable CAS 124-22-1 / ANTISTATIC

Lauramine, commonly known as Lauramine Oxide, is an amphoteric surfactant and emulsifier frequently incorporated into precision skincare formulations. It effectively cleanses and supports ingredient mixing without compromising the skin's natural lipid barrier, while also enhancing foam characteristics and providing mild conditioning benefits. Its versatility supports its use across diverse skin types.

Science

Mechanism of Action

Functioning as an amphoteric surfactant, Lauramine Oxide lowers the surface tension of liquids, which facilitates the uniform dispersion of ingredients and the creation of stable emulsions. As a cleansing agent, it aids in dislodging dirt, excess oil, and impurities from the skin. It acts as a foam booster, increasing lather volume and stability, and contributes mild conditioning, leaving the skin feeling soft. Additionally, it may possess mild antimicrobial properties.

Stability

Lauramine performs most effectively within a pH range of 6.0-8.0, though it remains functional between pH 4.0-9.0. Its performance and solubility significantly decline below pH 4.0. To prevent degradation, avoid prolonged exposure to high heat or UV light. Store between 5°C and 30°C. Heating above 60°C in the presence of aluminum is contraindicated due to potential corrosion and the generation of flammable hydrogen gas.

Conflicts

  • Strong acids (especially below pH 4.0)
  • Strong bases
  • Peroxides
  • Phenols
  • Halogenated materials
  • Nitrites (risk of nitrosamine formation)
  • Certain cationic polymers (potential for cloudiness or precipitation)
  • Zinc, copper, copper alloys, or galvanized containers for storage

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) has deemed Lauramine safe for use in cosmetics, subject to specific concentration or use limitations. The U.S. FDA also approves its use within recommended concentrations. It is generally well-tolerated and not associated with severe toxicity or side effects when used as directed. However, in highly concentrated forms, it has the potential to cause skin irritation and serious eye damage, necessitating precise formulation adherence.
