Description

Phosphatidylserines, C16-18 is a high-purity phospholipid fraction, specifically enriched with phosphatidylserine species containing palmitic (C16:0) and stearic (C18:0) fatty acid chains. This specific composition is critical for ensuring consistent performance and bioavailability in advanced nutritional and pharmaceutical formulations. It serves as an essential raw material for manufacturers in the nutraceutical, pharmaceutical, and cosmeceutical industries seeking to develop products that support cognitive function and cellular health.

Application

• Cognitive Health Supplements: Primary ingredient in nootropic and memory support formulations for its role in neuronal membrane integrity and signaling.
• Pharmaceutical Excipients: Used in advanced drug delivery systems, including liposomes and lipid nanoparticles, for targeted therapeutic applications.
• Sports Nutrition: Incorporated into products aimed at reducing exercise-induced cortisol levels and supporting post-exercise recovery.
• Clinical Nutrition: A key component in medical foods and enteral formulas designed for patients with age-related cognitive decline or neurological conditions.
• Cosmetic Actives: Employed in high-end skincare for its skin barrier repair and anti-aging properties, promoting cellular membrane health.
• Cell Culture Media: Used as a supplement in specialized mammalian cell culture to support cell growth and membrane function in bioprocessing.

Quality Control

Our Phosphatidylserines, C16-18 is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for purity, fatty acid profile, and oxidation parameters. Certificates of Analysis (COA) detailing results for identity, assay, residual solvents, and heavy metals are provided and can be tailored to meet specific USP, FCC, or pharmaceutical grade requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. For short-term use, store at 2-8°C. This material is hygroscopic and easily oxidized; allow the sealed container to reach room temperature before opening to prevent moisture condensation. Keep away from strong oxidizing agents.
