Pinus Pinaster Bark Extract

Product Description

Pinus Pinaster Bark Extract is a cosmetic-grade botanical active from Pinus pinaster (French maritime pine) bark, produced under direct factory supply with lot traceability and batch COA available upon request. Each lot is standardized against oligomeric proanthocyanidin (OPC) markers using UV spectrophotometry (Typical), supporting consistent formulator sourcing.

Unlike generic polyphenol blends, this extract delivers defined OPC-rich proanthocyanidins that modulate oxidative stress pathways and help support endogenous collagen and elastin metabolism in the dermis. The polyphenol profile is suited to stable in aqueous solution serums and hydro-alcoholic defense systems targeting photo-aging and barrier-related oxidative damage.

Indexed under INCI Pinus Pinaster Bark Extract and CosIng ref. 86849, maritime pine bark extract is widely specified in professional antioxidant, anti-pollution, and matrix-support lines. For cosmetic use only; formulation support and SDS are available upon request.

Key Benefits & Applications

This standardized maritime pine bark extract supports clinically oriented antioxidant and dermal matrix applications across leave-on skincare and body care systems.

• Delivers OPC-mediated free radical scavenging for environmental oxidative stress defense in antioxidant serums at 0.5–2.0% w/w.
• Supports fibroblast collagen synthesis to promote a firmer, more resilient dermal matrix in anti-aging creams and essences.
• Modulates inflammatory signaling pathways for calmer, balanced skin in sensitive-skin toners and post-exposure care.
• Helps defend against photo-induced oxidative damage, supporting photo-aging protection in day creams and UV-aftercare lotions.
• Supports elastin network integrity for improved skin elasticity in firming face and body formulations.
• Reinforces stratum corneum barrier function and reduces TEWL in barrier-repair moisturizers and post-treatment balms.

Formulation Guidelines

Pinus Pinaster Bark Extract is compatible with aqueous and hydro-alcoholic systems when processed within the recommended pH and temperature window. Avoid co-formulating with strong oxidizers in the same phase.

• Serum / Essence: 0.5–2.0% w/w; add below 40°C during cool-down for optimal OPC stability in aqueous solution.
• Day Cream / Lotion: 0.5–1.5% w/w; maintain pH 4.0–6.5 for proanthocyanidin stability and TEWL-control performance.
• pH Window: 4.0–7.0; performance may decline above pH 7.5 (Suggested).
• Compatibility: Pairs with humectants and peptide actives; separate from strong peroxides or highly alkaline phases.
• Processing: Pre-dispersion in glycerin or pentylene glycol (Typical 1:1) improves incorporation into cold-process emulsions.
• Synergy: Combine with Hyaluronic Acid for enhanced hydration and antioxidant defense in transdermal delivery serums.
