Ceramide NP N-Octadecanoylphytosphingosine Skin Barrier Repair Cosmetic Raw Material CAS 100403-19-8

Ceramide NP, also known as N-Octadecanoylphytosphingosine, is a sphingolipid active ingredient with high homology to human stratum corneum lipids and a core raw material for skin barrier repair. This cosmetic-grade product is white crystalline powder with liposoluble property. It dissolves in oils and synthetic esters, and water-dispersible grade is also available for emulsion systems. Ceramide NP fills lipid gaps in stratum corneum, reconstructs keratin brick-and-mortar structure, locks internal skin moisture and reduces transepidermal water loss. It relieves dry flaking, roughness and tightness, calms redness and sensitivity, strengthens skin barrier defense and alleviates discomfort caused by external irritants. It is ideal for sensitive skin, dry sensitive skin and damaged barrier formulas. It features excellent skin affinity and extremely low irritation with good compatibility with native skin lipids. We supply high purity Ceramide NP powder. Every batch passes full inspection including HPLC assay, heavy metal and microbiology test. Samples are available for formulation trial, accelerated stability test and efficacy evaluation. Full documents including COA, TDS and SDS are supplied. The product complies with REACH, GMP, ISO22716, FDA, HALAL, KOSHER standards for global cosmetic filing.

Ceramide NP is the core ingredient for barrier repair and soothing moisturizing formulas, widely used in sensitive repair, dry skin hydration and anti-irritation skincare products. It is commonly incorporated into repair serums, soothing toners, barrier lotions, repair creams, sensitive-skin masks, eye creams, baby care and hair care items. It has excellent formulation compatibility and can be compounded with panthenol, sodium hyaluronate, ectoin, peptides, cholesterol, fatty acids and soothing botanical extracts to build complete lipid system and enhance barrier repair and moisturizing effects. Oil-soluble Ceramide NP is recommended to be added in oil phase, and water-dispersible grade can be added after emulsification. It should be sealed, protected from light and stored under cool conditions to prevent high-temperature oxidation. It fits mid-to-premium skincare brands focusing on barrier repair and sensitive skin care. We provide formulation suggestions and complete compliance documents to support new product development and export filing for cosmetic manufacturers and brands.

We provide standard industrial packing solutions and support customized packaging upon request. There are two regular packing sizes: 1kg vacuum aluminum foil bag for sample testing, laboratory formulation trial and small‑batch production; 25kg food‑grade sealed plastic drum for mass industrial production procurement. All packages are equipped with internal moisture‑proof layers to block moisture and light, preventing activity loss of raw materials during storage and transportation. It should be stored in sealed, light‑proof, cool and dry conditions, away from heat sources, open flames and strong oxidants, and avoid drastic temperature changes. The shelf life is 24 months for unopened products. Once opened, it is recommended to consume as soon as possible. Residual materials need to be re‑sealed and stored away from light under refrigeration to avoid degradation of active components. We also offer neutral packing and private label packing services to meet export and repackaging demands of different brands.
