SODIUM PHENOXIDE.

Avoid CAS 139-02-6 / ANTIMICROBIAL

Sodium Phenoxide, the sodium salt of phenol, functions as an antimicrobial agent and preservative by inhibiting microbial proliferation. While it possesses antiseptic qualities, its inherent caustic and corrosive properties present a substantial risk of irritation and adverse skin reactions.

Summary

Antimicrobial

Science

Mechanism of Action

Sodium Phenoxide operates by inhibiting microbial growth, leveraging its phenoxide anion's strong nucleophilic and basic properties for antiseptic efficacy. This mechanism allows it to actively suppress microorganisms on the skin.

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

Classified as harmful and corrosive, Sodium Phenoxide solutions are notably caustic, carrying a high risk of inducing irritation, inflammation, and dryness, especially when co-formulated with other potentially problematic ingredients. Veterinary data indicated that 3-5% aqueous solutions exhibited weak toxic effects in warm-blooded animals, implying heightened concerns at greater concentrations. The substance is also recognized as a High Production Volume (HPV) chemical.
