STRONTIUM PEROXIDE.

Questionable CAS 1314-18-7 / BLEACHING, OXIDISING

Strontium Peroxide is an inorganic compound primarily utilized as an oxidizing agent. It is known to release strontium ions and active oxygen species upon decomposition, offering potential for bleaching and antiseptic applications. However, its integration into formulations presents significant challenges due to inherent instability and documented irritant properties.

Summary

Oxidizing Agent Bleaching Agent

Science

Mechanism of Action

As a potent oxidizing agent, Strontium Peroxide functions by liberating strontium ions (Sr2+), hydrogen peroxide, and oxygen molecules. This molecular release contributes to increased local oxygen tension. Its documented bleaching capability on hair or skin is attributed to altering the chemical structure of substances through oxidation (addition of oxygen) or reduction (removal of hydrogen).

Stability

Strontium Peroxide exhibits slow decomposition in the presence of water and is highly sensitive to heat, shock, catalysts, and reducing agents. For optimal stability, it must be stored under recommended conditions, strictly avoiding moisture and air.

Conflicts

  • Combustibles (e.g., wood, paper, oil)
  • Hydrocarbons (e.g., fuels)
  • Moisture/water (causes slow decomposition; violent reaction possible with water in containers)

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

Strontium Peroxide is categorized as a hazardous substance under OSHA 29 CFR 1910.1200, with GHS hazard statements indicating it causes skin irritation, serious eye damage, and respiratory irritation. While the EU Cosmetics Regulation has approved its use in cosmetics following an SCCS assessment, this approval is contingent upon strict restrictions regarding purity criteria, maximum concentration, and specific product categories. EWG Skin Deep rates it as 'Restricted' with 'High' use limitations, highlighting significant safety considerations.

Verdict

Questionable

Given its classification as a hazardous substance with high irritation potential, substantial formulation challenges, and the absence of specific clinical studies for Strontium Peroxide itself demonstrating direct skincare benefits, its inclusion in precision skincare formulations is highly questionable despite restricted cosmetic approval.
