LACTAMIDE DEA.

Questionable / SKIN CONDITIONING

LACTAMIDE DEA is a skin conditioning humectant derived from lactic acid, designed to attract and retain moisture, thereby supporting skin hydration. Its use requires careful formulation to adhere to specific safety guidelines, particularly regarding free diethanolamine levels.

Summary

Skin conditioning Humectant

Science

Mechanism of Action

LACTAMIDE DEA operates by binding water molecules to the skin's surface, functioning as a humectant to enhance and preserve moisture content, contributing to a conditioned skin feel.

Stability

This ingredient, an amide derivative, is prone to hydrolysis when exposed to strong acidic or basic conditions, which can break it down into lactic acid and ammonia. Optimal stability is achieved near a neutral pH range, with degradation accelerating at extreme pH values or higher temperatures, and requiring the presence of water.

Conflicts

  • Should not be incorporated into cosmetic products where N-nitroso compounds could potentially form.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

Regulatory bodies including the CIR Expert Panel, the SCCS of the EU Commission, and the FDA have assessed LACTAMIDE DEA. It is considered safe for cosmetic use under specific conditions: formulations must be non-irritating, and free diethanolamine (DEA) levels must not surpass safe thresholds established by the Panel. Furthermore, it is critical to avoid its use in products where N-nitroso compounds can be generated. For products intended for prolonged skin contact, the total concentration of ethanolamines should not exceed 5%. Consumers concerned about DEA-related ingredients are advised to review product labels.

Verdict

Questionable

While offering humectant properties, LACTAMIDE DEA's use is subject to significant regulatory restrictions regarding formulation, free DEA levels, and potential N-nitroso compound formation, making its inclusion questionable for precision skincare without stringent controls.
