DEA-LINOLEATE.

Valuable CAS 59231-42-4 / ANTISTATIC, SURFACTANT - EMULSIFYING, VISCOSITY CONTROLLING

A specialized conditioning agent and surfactant that combines diethanolamine with linoleic acid to provide dual-action cleansing and barrier support. It serves as a lipid-replenishing ingredient that helps stabilize formulations while delivering essential fatty acids to the skin surface.

Science

Mechanism of Action

DEA-LINOLEATE operates by supplying linoleic acid, a critical component for ceramide synthesis and the maintenance of the epidermal lipid barrier. It promotes the migration of keratinocytes and neutrophils to accelerate wound healing and regulates epidermal differentiation to enhance barrier function. Furthermore, it exhibits anti-inflammatory properties and can assist in skin brightening by inhibiting tyrosinase activity and encouraging mild epidermal shedding.

Dusting Analysis

Not commonly dusted

As a functional surfactant and conditioning agent, DEA-LINOLEATE is rarely used as a standalone 'hero' ingredient for marketing, making it less prone to 'label dusting' than active botanical extracts.

Stability

The linoleic acid component is highly sensitive to oxidative stress; formulations should be protected from air and light. Oxidation rates remain relatively stable between pH 5.0 and 7.5.

Synergies

  • Antioxidants (tocopherol)
  • Ceramides
  • Chelating agents

Conflicts

  • Strong oxidizing agents
  • Heavy metals
  • Nitrosating agents

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

Safe when formulated to be non-irritating. A critical restriction exists: it must not be used in products containing N-nitroso compounds due to the risk of forming nitrosamines.
