Ceramide （NP AP EOP NS）Ceramide Series Products
Ceramide applies to skincare formulation R&D for skin barrier care. Indicate your type (NP/AP/EOP/NS or blended grade) upon inquiry. Xi'an Wanlv provides matching specifications, documents and sample support.
Overview
What is Ceramide?Ceramide is a key intercellular lipid component in the human stratum corneum, accounting for 40‑50% of total stratum corneum lipids, and is commonly known in the industry as “molecular rivet”. Its molecule consists of a sphingosine backbone linked to fatty acids via amide bonds, and it takes part in the formation of skin barrier structure. Factors such as age, external environment and cleansing habits may alter endogenous ceramide levels, which in turn affects skin lipid conditions. This product series includes Ceramide NP, AP, EOP, NS and complex ceramide. Manufactured by bio‑fermentation or chemical synthesis processes, the material appears as white powder. With molecular structures similar to skin‑native lipids, it exhibits favorable skin‑compatible properties and is a widely‑used skin‑protective active raw material in the cosmetic industry.
Key Parameters
Applications
Cosmetic & Skincare Applications
1. Cream / Skin Lotion: Complex Ceramide NP/AP for formulations intended for dry‑skin and skin with low tolerance. Recommended dosage: 0.1‑2%. Can be combined with cholesterol and free fatty acids. 2. Serum: Liposomal / nano‑emulsified ceramide for light‑weight systems, suitable for oily‑sensitive skin formulations. 3. Mask (sheet / wash‑off): For formulations targeting soothing‑oriented skincare concepts. 4. Skin Oil: Oil‑soluble ceramide features good solubility in oil systems with low crystallization tendency, ideal for oil‑based formulations. 5. Cleanser: Pseudo‑ceramide or low‑dosage ceramide for cleansing‑type skincare formulas. 6. Color Cosmetics: Foundation and primer formulas to build skin‑lipid‑related system and improve cosmetic application feel.
Scalp & Hair Care
Applicable to scalp serum, hair conditioner, hair mask, shampoo and other hair‑wash formulations. It participates in scalp lipid‑structure construction and suits formulation development for post‑perm & post‑color hair care.
Baby & Infant Care
Infant stratum corneum structure is not fully developed and prone to moisture loss. It can be used in baby moisturizing cream, body lotion and 2‑in‑1 wash‑&‑bath formulations. Fermentation‑derived ceramide fits baby‑care formula development.
Product FAQ
What are the differences among Ceramide NP / AP / EOP / NS?
All are listed in China Inventory of Existing Cosmetic Ingredients. They differ in INCI names, CAS numbers, fatty‑acid chain lengths, melting points and crystallization properties. Ceramide NP and AP are the most widely used grades; EOP and NS are mostly applied in complex blends. Single components are available for purchase, and custom blended powders can also be provided for your projects.
What is the difference between fermentation‑derived ceramide and chemically‑synthesized ceramide?
They differ in manufacturing process, stereoconfiguration, melting point and crystallization behavior. Fermentation‑derived ceramide shows high stereochemical similarity to human sphingolipids, while chemically‑synthesized ceramide offers prominent cost advantages. Both are compliant cosmetic raw materials. Selection can be made according to end‑product positioning.
Why is pure ceramide powder poorly soluble in water and how to dissolve it in formulation?
High‑purity ceramide powder is a lipid‑like substance, practically insoluble in water but soluble in hot oils and certain organic solvents. Common processing methods: ① Oil‑phase high‑temperature dissolution: fully melt in oil phase at 80‑90 °C prior to emulsification; ② Pre‑dissolve in solvents such as isocetyl alcohol to reduce crystallization risk upon cooling; ③ Adopt ready‑made liposomal ceramide liquid or pre‑dispersed oil‑soluble products to simplify formulation operations.
What is its regulatory status in China? Is it a new cosmetic raw material?
Ceramide NP, AP, EOP and NS are included in China Inventory of Existing Cosmetic Ingredients (2021 Edition). They are not new cosmetic raw materials and can be legally used for domestic cosmetic production. Other ceramide subtypes not covered by the inventory shall go through new cosmetic raw material registration or filing procedures.
