Description

C16 Ceramide CAS NO 24696-26-2 is a high-purity, synthetic ceramide analog, specifically N-palmitoyl-D-erythro-sphingosine. This compound is a critical lipid molecule that serves as a fundamental building block for the skin's natural barrier function. It is essential for manufacturers in the cosmetic, pharmaceutical, and advanced dermatological research sectors seeking to develop products that enhance skin hydration, repair, and protection.

Application

• Premium Cosmetic & Skincare Formulations: A key active ingredient in anti-aging serums, moisturizers, and barrier repair creams to improve skin elasticity and reduce transepidermal water loss (TEWL).
• Pharmaceutical Topicals: Used in medicated creams and ointments for treating eczema, psoriasis, and other dermatological conditions characterized by impaired skin barrier function.
• Hair Care Products: Incorporated into conditioners and treatments to strengthen hair cuticles, improve shine, and prevent moisture loss from hair strands.
• Biomedical & Cell Biology Research: Serves as a standard or reagent in studies of sphingolipid metabolism, apoptosis (programmed cell death), and cell signaling pathways.
• Advanced Dermal Delivery Systems: Utilized in the development of liposomes and other nano-carriers to enhance the penetration and stability of active ingredients.
