Insufficient Data CAS 91722-18-8 / FRAGRANCE

Picea Glauca Leaf Extract, derived from White Spruce, provides antioxidant protection by neutralizing free radicals, potentially mitigating visible signs of aging and oxidative damage. It also functions as a skin conditioning agent, enhancing skin surface feel, with traditional uses suggesting antimicrobial and anti-inflammatory properties.

Science

Mechanism of Action

Operating primarily as an antioxidant, Picea Glauca Leaf Extract actively scavenges free radicals, thereby protecting skin cells from oxidative stress and potentially reducing the appearance of premature aging. Its role as a skin conditioning agent involves forming a protective layer on the epidermal surface. Furthermore, component analysis and traditional applications indicate potential antimicrobial activity against bacteria and fungi, alongside anti-inflammatory effects that could contribute to soothing irritated skin.

Stability

To maintain optimal stability and minimize potential for sensitization, Picea Glauca Leaf Extract, particularly its essential oil derivatives, should be formulated to ensure peroxide levels remain below 10 millimoles peroxide per liter. This is typically achieved by incorporating antioxidants during the production process.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has not evaluated Picea Glauca Leaf Extract. While the FDA lists 'SPRUCE NEEDLES AND TWIGS, OIL (PICEA SPP.)' as a flavoring agent, the International Fragrance Association (IFRA) identifies sensitization as a critical concern for Picea glauca leaf extract, absolute, or oil. To mitigate this, formulators are advised to ensure peroxide values are kept below 10 millimoles peroxide per liter, often by integrating antioxidants during manufacturing. The essential oil form may also cause slight respiratory irritation if inhaled, and ingestion is considered potentially harmful.

Verdict

Insufficient Data

While offering potential antioxidant and skin conditioning benefits, the lack of extensive clinical data, absence of CIR review, and identified sensitization risk from IFRA necessitate careful consideration and proper formulation.
