LECITHINAMIDE DEA.

Valuable CAS 91053-51-9 / ANTISTATIC, HAIR CONDITIONING, SURFACTANT - FOAM BOOSTING, VISCOSITY CONTROLLING

Lecithinamide DEA is a versatile cosmetic ingredient primarily used to enhance the sensory and performance attributes of cleansing and topical formulations. It effectively modifies foam characteristics, acts as a thickening agent, and provides a lubricating effect, particularly beneficial for delicate skin.

Summary

Antistatic Agent Emulsifying Agent Viscosity Controlling Agent Foam Boosting Agent Foam Stabilizing Agent Gelling Agent (for anionic detergents) Lubricant

Science

Mechanism of Action

This diethanolamide functions within cosmetic matrices by improving the quality and stability of foams, mitigating the coarser effects of primary foaming agents. It demonstrates the ability to gel anionic detergents, regulate product viscosity, and serve as an efficient lubricant in cleansers designed for sensitive skin. Additionally, it contributes emulsifying and antistatic properties to formulations.

Dusting Analysis

Not commonly dusted

Lecithinamide DEA is valued for its specific functional contributions to product formulation, such as foam modification and viscosity control, rather than direct 'active' skin benefits. Consequently, it is not typically characterized as a 'dusted' ingredient, which refers to components often overhyped for superficial skin claims.

Stability

Optimal pH stability data specific to Lecithinamide DEA is not documented. However, for a chemically related diethanolamide (Oleamide DEA), stability has been noted within a pH range of 5-7.

Conflicts

  • Must not be incorporated into cosmetic products where the potential for N-nitroso compound formation exists.
  • Formulations must be carefully designed to be non-irritating and to ensure free diethanolamine (DEA) levels do not exceed recognized safety limits.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Unknown

The CIR Expert Panel considers diethanolamides, including Lecithinamide DEA, safe under specific conditions: formulations must be non-irritating, and free diethanolamine (DEA) content must remain below established safe thresholds. Strict avoidance is mandated in products where N-nitroso compounds could form. While no specific maximum concentration for Lecithinamide DEA is provided, related DEA amides have been deemed safe up to approximately 50%, with some leave-on applications limiting free ethanolamines to 5% at a maximum use concentration of 40%.

Our Assessment

Verdict

Valuable

Lecithinamide DEA is a valuable functional ingredient, enhancing foam characteristics, thickening, and providing a lubricating effect particularly in cleansers for delicate skin, provided formulations rigorously adhere to safety restrictions concerning free diethanolamine levels and nitrosamine prevention.
