COPPER SULFATE.

Valuable CAS 7758-98-7 / SKIN CONDITIONING

Copper sulfate is a mineral salt recognized for its diverse actions on the skin, including potent antimicrobial, antibacterial, and antifungal properties. It supports the skin's natural regeneration processes and collagen synthesis, making it beneficial for compromised or irritated skin conditions.

Summary

Antimicrobial Antibacterial Antiseptic Fungicide Skin conditioning Promotes collagen production Supports skin regeneration Anti-inflammatory Wound healing

Science

Mechanism of Action

Copper sulfate exerts its beneficial effects by acting as an antimicrobial, antibacterial, antiseptic, and fungicide. It eliminates harmful microorganisms through the generation of reactive oxygen species (ROS) via copper's redox properties, leading to cellular damage, disruption of membrane integrity, DNA fragmentation, and interference with essential metabolic enzymes. Additionally, copper plays a crucial role in promoting collagen production, stabilizing extracellular matrix (ECM) skin proteins, and stimulating angiogenesis, which collectively contribute to enhanced skin regeneration, efficient wound healing, and anti-inflammatory responses.

Key findings

  1. 01 A dermo-cosmetic product formulated with 0.1% copper sulfate (in combination with 3% sucralfate and 0.1% zinc sulfate) demonstrated significant improvement or complete clearing of hand eczema symptoms in 56% of subjects after 1 week, and 66% after 3 weeks of consistent application.
  2. 02 Topical application of a 1% copper sulfate solution has been effectively used for treating phosphorus burns on the skin.

Stability

Copper sulfate is highly soluble in water and should be stored in a dry, cool environment, protected from direct sunlight and moisture. While a specific optimal pH range for copper sulfate's stability is not provided, related copper compounds like copper peptides are sensitive to low pH environments, where acidic conditions can dissociate copper ions from their complexes, potentially reducing their activity and stability within a formulation.

Synergies

  • Sucralfate
  • Zinc sulfate

Conflicts

  • Extremely low pH environments (potential for copper ion dissociation)

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

The CIR Expert Panel noted 'limited sensitization data' for copper sulfate. The U.S. EPA classified it as having very low dermal toxicity (dermal LD50 > 2000 mg/kg in rats) but as a severe eye irritant. It is generally considered non-irritating and non-sensitizing when applied topically, though rare cases of allergic dermatitis (0.34% in a 10-year study) have been reported. EWG indicates a high irritation potential for skin, eyes, or lungs, suggesting careful formulation and usage, especially around the eyes.

Verdict

Valuable

Copper Sulfate is a valuable ingredient for its powerful antimicrobial, wound-healing, and skin-regenerating capabilities, making it particularly effective for targeted treatments of compromised or irritated skin, provided eye contact is avoided.
