Valuable CAS 14960-06-6 / 26256-79-1 / ANTISTATIC, CLEANSING, FOAMING, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING

Sodium Lauriminodipropionate is a versatile amphoteric surfactant and cleansing agent. It excels at reducing surface tension to ensure even product distribution and enhance the removal of impurities, making it highly effective in various cleansing formulations.

Summary

Surfactant Cleansing Agent Foam Booster

Science

Mechanism of Action

This ingredient operates primarily as a surfactant, effectively lowering the surface tension of liquids to facilitate superior wetting, emulsification, and dispersion of dirt and oils. Its unique amphoteric nature allows it to adopt both positive and negative charges, enabling adaptive and effective interaction with diverse impurities across a broad pH spectrum. Additionally, it functions as a foam booster, enhancing lather, and can provide anti-static benefits.

Key findings

  1. 01 Human Repeated Insult Patch Test (HRIPT) studies demonstrated no delayed contact hypersensitivity when incorporated into formulated products, specifically a foaming face wash at 2.2% (active) and a shampoo at 3.5% (active).
  2. 02 Shampoo formulations containing 3.56% (active) did not induce ocular lesions or a significant increase in albumin levels in human tears, with only minimal reports of stinging or dryness.

Stability

Highly stable across the entire pH range, a characteristic attributed to its amphoteric nature which allows it to adapt effectively to different pH environments. A 30% active solution typically registers a neutral pH between 6.0 and 7.0.

Sensitization risk Low

The CIR Expert Panel concluded in 2011/2012 that Sodium Lauriminodipropionate is safe for cosmetic use within current practices and concentrations. While concentrated forms (e.g., 10-16% on rabbit skin) can be irritating, human studies with formulated products (2.2% in face wash, 3.5% in shampoo) showed no dermal sensitization or significant irritation. It is permitted for use in cosmetics in the European Union. EWG rates it 'LOW' across various toxicity categories.
