Stability

To maintain stability and efficacy, Picea Glauca Branch/Leaf Oil should be stored in its original, tightly closed packaging in a dry, well-ventilated area, protected from direct sunlight. Critical to its stability are peroxide levels, which must be kept below 10 millimoles per liter, ideally achieved through the inclusion of antioxidants during production.

Conflicts

  • Direct, undiluted application to skin (potential for severe irritation and allergic reactions)
  • Formulations with high peroxide levels (exceeding 10 mmol/L, requiring antioxidant addition)

Sensitization risk High

Listed by the FDA, this ingredient is associated with a high risk of sensitization according to IFRA guidelines. It is classified as causing skin irritation (H315), potentially leading to allergic skin reactions (H317), and serious eye damage (H318). Furthermore, it is harmful if swallowed (H302) and may be fatal if swallowed and enters airways (H304). IFRA mandates that essential oils from the Pinacea family, including Picea Glauca, must be formulated with peroxide levels kept at the lowest practicable level, ideally below 10 millimoles peroxide per liter, typically achieved by adding antioxidants.

Verdict

Questionable

While Picea Glauca Branch/Leaf Oil offers notable antimicrobial and anti-inflammatory properties, its high risk of skin irritation and sensitization, alongside specific formulation stability requirements, renders its use in precision skincare highly questionable without stringent control and justification.
