C14-15 PARETH-7.

Valuable CAS 68951-67-7 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A synthetic non-ionic surfactant and emulsifier derived from a blend of C14-15 fatty alcohols reacted with 7 moles of ethylene oxide. This amphiphilic molecule is essential for creating stable, sophisticated textures and ensuring that oil and water-based components remain perfectly integrated.

Surfactant Cleansing Agent Emulsifier Solubilizer

Science

It functions by reducing the interfacial tension between immiscible phases, allowing for the formation of stable emulsions. In cleansing systems, its hydrophobic tail binds to sebum and impurities, while its hydrophilic head remains water-soluble, facilitating the lifting and removal of debris during rinsing.

Key findings

  1. 01 Clinical sensitization assessments (OECD TG 406) at 50% concentration confirmed zero evidence of skin sensitization over a 48-hour period.
  2. 02 Draize irritation testing indicates that while the undiluted (100%) substance is a severe irritant, potential for irritation is significantly mitigated at concentrations below 10%.

As a functional emulsifier and surfactant, it is rarely used for 'marketing claims.' Concentrations below 0.1% are generally insufficient to provide any meaningful impact on the structural integrity or cleansing performance of a formula.

Stability

Displays exceptional chemical stability across a wide pH range. It is particularly effective at increasing viscosity when paired with hydrophobically modified rheology modifiers like HEUR polymers.

Synergies

  • HEUR rheology modifiers
  • Lipophilic active ingredients
  • Fragrance oils

Conflicts

  • Strong oxidizing agents
  • High-salt environments when combined with specific anionic surfactants
