Tallow Dihydroxyethyl Betaine

TALLOW DIHYDROXYETHYL BETAINE is a zwitterionic surfactant known for its gentle cleansing and conditioning properties. It effectively lowers surface tension to facilitate the removal of impurities while simultaneously aiding in maintaining skin health. Its mild nature is particularly beneficial, as it can reduce the irritant potential of other surfactants within a formulation.

Science

Mechanism of Action

This zwitterionic surfactant operates by significantly reducing the surface tension of liquids, which allows for a harmonious blend of typically immiscible oil and water. This action is crucial for efficient cleansing, as it enables the detachment and removal of fatty residues and soil particles from the skin's surface. Concurrently, it functions as a skin conditioning agent, actively contributing to the maintenance of the skin's integrity and healthy state.

Stability

TALLOW DIHYDROXYETHYL BETAINE is inherently stable, though it exhibits susceptibility to oxidation, indicating that the inclusion of antioxidants may be beneficial in formulations to preserve product integrity. It demonstrates excellent compatibility with other ingredients and maintains efficacy in hard water conditions. Strict control of residual amine and chloroacetic acid content is essential during its synthesis to ensure purity.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

In its liquid form, TALLOW DIHYDROXYETHYL BETAINE presents a low risk of irritation to both skin and eyes, aligning with its classification as a mild surfactant. A notable characteristic is its ability to mitigate irritation potentially caused by other surfactants in a blend. While the Cosmetic Ingredient Review (CIR) has assessed related betaine compounds, acknowledging their anti-irritating effects, a definitive CIR status for this specific ingredient (CAS: 70750-46-8) is currently 'insufficient data'. It is also recognized for being biodegradable and is considered suitable for formulations intended for children's washing products.
