Description

C22 Ceramide is a high-purity, long-chain ceramide (N-acylsphingosine) specifically featuring a C22 fatty acid chain, identified by CAS NO 869501-30-4. This compound is a critical bioactive lipid molecule essential for maintaining the structural integrity and barrier function of cell membranes, particularly in the stratum corneum. It is a vital ingredient for manufacturers in the advanced cosmetic, pharmaceutical, and high-end nutraceutical industries seeking to develop products for skin barrier repair, hydration, and anti-aging.

Application

• Premium Cosmetic & Skincare Formulations: A key active ingredient in anti-aging serums, moisturizers, and creams designed to restore the skin's lipid barrier, improve hydration, and reduce trans-epidermal water loss (TEWL).
• Pharmaceutical Topicals: Used in medicated creams and ointments for the treatment of dermatological conditions like eczema, psoriasis, and ichthyosis, where skin barrier dysfunction is a primary concern.
• Advanced Nutraceuticals: Incorporated into dietary supplements targeting skin health from within, often in lipid-based delivery systems for enhanced bioavailability.
• Biomedical Research: Serves as a standard or reagent in lipidomics research, cell signaling studies, and investigations into apoptosis, sphingolipid metabolism, and membrane biophysics.
• Hair Care Products: Formulated into conditioners and treatments to strengthen the hair cuticle, improve shine, and protect against environmental damage.
• Model Lipid Systems: Used in the development of artificial membranes, liposomes, and other drug delivery vehicles due to its specific chain length and physicochemical properties.
