POTASSIUM TROCLOSENE.

Avoid CAS 2244-21-5 / ANTIMICROBIAL

Potassium Troclosene, also identified as Potassium Dichloroisocyanurate, functions as a powerful chlorine-releasing agent, primarily recognized for its potent antimicrobial and disinfecting capabilities. It is also classified as a robust oxidizing agent.

antimicrobial/preservative oxidizing agent

Science

This ingredient exerts its primary function through the controlled release of available chlorine. This active chlorine species then acts as a broad-spectrum disinfectant, effectively targeting and inactivating various microorganisms.

Transparency

Not commonly dusted

Due to its significant potential for skin and eye irritation, its classification as a strong oxidizer, and its extensive incompatibilities with common cosmetic ingredients, Potassium Troclosene is not considered suitable for precision skincare formulations and is highly unlikely to be utilized in such products.

Stability

Potassium Troclosene presents as a white solid with a distinct chlorine odor, dissolving readily in water. However, the solid material may react vigorously upon contact with water, leading to the release of chlorine gas. It is slightly hygroscopic, and sustained exposure to elevated temperatures can induce vigorous decomposition and container rupture.

Conflicts

  • Water (vigorous reaction, chlorine gas release)
  • Ammonium compounds (vigorous reaction)
  • Hydrated salts (vigorous reaction)
  • Heat/fire (vigorous decomposition, rupture hazard)
  • Combustible materials (accelerates burning)
  • Reducing agents (violent reaction)
  • Organic compounds
  • Easily chlorinated or oxidized materials
  • Ammonia
  • Urea
  • Other nitrogen compounds
  • Calcium hypochlorite
  • Other alkalies
  • Moisture

Safety

CIR Status
Not reviewed
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically assessed Potassium Troclosene for use in cosmetics. Globally Harmonized System (GHS) classifications identify it as an oxidizer, harmful if swallowed, a cause of serious eye irritation (Category 1), and a potential respiratory irritant. It is also designated as a Category 2 skin irritant, capable of inducing itching and redness upon skin contact. As a strong oxidizer, it presents a significant fire risk when in contact with organic substances.

Our Assessment

Avoid

Due to its classification as a severe irritant and strong oxidizer, absence of a cosmetic safety review, and extensive formulation incompatibilities, Potassium Troclosene is deemed unsuitable for inclusion in precision skincare formulations and should be avoided.
