Description

C15 D-Erythro Ceramide (D18:1/15:0) is a high-purity, synthetic sphingolipid characterized by its specific stereochemistry and fatty acid chain length. This compound is a critical building block for advanced lipid research and the development of sophisticated cosmetic and pharmaceutical formulations. It is essential for scientists and manufacturers in the cosmeceutical, dermatological research, and high-end skincare industries who require precisely defined lipid components to study skin barrier function, develop bioactive delivery systems, and create premium anti-aging products.

Application

• Skin Barrier Research: Used as a standard or active component in studies investigating the structure and function of the stratum corneum lipid matrix.
• Cosmeceutical Formulations: Incorporated into premium anti-aging serums, creams, and lotions designed to restore and reinforce the skin's natural moisture barrier.
• Lipidomics & Analytical Standards: Serves as a critical reference standard for the identification and quantification of ceramide species in complex biological samples via LC-MS or HPLC.
• Biomimetic Delivery Systems: A key lipid for constructing liposomes, niosomes, or other nano-carriers designed for targeted and sustained delivery of active ingredients in dermatological products.
• Cell Signaling Studies: Employed in biochemical research to elucidate the role of specific ceramide species in cellular processes like apoptosis, differentiation, and stress response.
• Model Membrane Systems: Used to create defined lipid bilayers for biophysical studies of membrane permeability, protein-lipid interactions, and fusion events.

Quality Control

Our C15 D-Erythro Ceramide is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (NMR, IR), to ensure it meets the stringent requirements for research and formulation. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the product to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake.
