TRIDECETH-19 CARBOXYLIC ACID.

Valuable CAS 68412-55-5 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

TRIDECETH-19 CARBOXYLIC ACID is a mild anionic surfactant primarily functioning as a cleansing, foaming, and wetting agent in skincare formulations. It efficiently reduces surface tension, enabling oil and water to mix, and also supports formulation texture and stability.

Summary

Cleansing Foaming Surfactant Wetting Agent Solubilizer

Science

Mechanism of Action

This ingredient operates by lowering the surface tension of liquids, facilitating the mixing of immiscible substances like oils and water, which is fundamental for effective cleansing. It also acts as a foaming agent, trapping air within liquid formulations, and functions as a solubilizer for water-insoluble components, enhancing product stability and spreadability.

Stability

TRIDECETH-19 CARBOXYLIC ACID exhibits strong wetting capabilities across a broad range of pH and temperature conditions. Its carboxylic acid group, with a typical pKa of 4-5, allows for neutralization with alkaline substances, which can modify its functional properties within a formulation.

Conflicts

  • Strong bases (due to its carboxylic acid group, leading to salt formation)
  • Certain metal ions (may form insoluble salts)
  • Ingredients that react with carboxylic acid groups (e.g., strong oxidizing agents, alcohols in esterification conditions)

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Trideceth ingredients, including TRIDECETH-19 CARBOXYLIC ACID, safe for use in cosmetic products when properly formulated to be non-irritating. The panel noted that these are large, insoluble molecules not expected to readily penetrate the skin, alleviating concerns regarding dermal irritation or sensitization. Furthermore, the FDA permits the use of Trideceth ingredients as indirect food additives in certain food packaging materials.
