Ceramide NP
Name and spec: Ceramide NP 90%
CAS: 10003-19-8
Ceramide is a class of amide compounds formed by dehydration of long-chain fatty acids and the amino group of sphingosine, mainly ceramide phosphorylcholine and ceramide phosphorylethanolamine. Phospholipids are the main components of cell membranes. 40%~50% of sebum in the stratum corneum is composed of ceramide. Ceramide is the main part of the intercellular matrix and plays an important role in maintaining the balance of moisture in the stratum corneum. Ceramide has a strong ability to associate with water molecules. It maintains skin moisture by forming a reticular structure in the stratum corneum. Therefore, ceramide has the function of maintaining skin moisture. Ceramide exists in all eukaryotic cells and plays an important role in regulating life activities such as cell differentiation, proliferation, apoptosis, and aging. As the main component of intercellular lipids in the stratum corneum of the skin, ceramide not only acts as a second messenger molecule in the sphingomyelin pathway, but also plays an important role in the formation process of the epidermal stratum corneum. It has the functions of maintaining skin barrier, moisturizing, anti-aging, whitening and disease treatment.
