COSMETIC ACTIVE
Ceramide 99% — Barrier Lipid
Ceramide is bought on purity and on the ceramide type, because the barrier function depends on which species is present. At 99% the material is a purified lipid and needs a carrier or a solubilisation step before it can enter an aqueous formula.
COA-Backed Specification
| Identity | Ceramide (source declared per lot) |
|---|---|
| Plant part | Not applicable (purified lipid) |
| Form and colour | White to off-white powder |
| Assay | Ceramide 99.0% |
| Method | HPLC |
| Particle size | 98% through 80 mesh |
| Loss on drying | Within the limits of the approved specification |
| Ash | Within the limits of the approved specification |

| Microbiological limits | Within the limits of the approved specification |
| Shelf life | Two years when stored properly |
Limits shown are the agreed specification. Result values are issued on the batch-specific certificate of analysis.
Buyer Decision Guide
Ask which ceramide species the lot contains and what the source is. A 99% figure alone does not tell you whether it fits your barrier claim.
- Assay: ceramide 99.0% by HPLC, with the species profile declared on the COA.
- Source: declared per lot. Plant-derived and fermentation-derived ceramides behave differently in formula.
- Solubility: lipid-soluble; requires a solubiliser or liposomal step for aqueous systems.
- Appearance: white to off-white powder. Discolouration indicates oxidation of the fatty acid chain.
- Handling: keep sealed and cool; ceramides are sensitive to moisture and heat.
- Documentation: COA, specification sheet and SDS with each batch.
How This Grade Differs
The site lists a 30% ceramide powder. This page is the 99% grade: the higher purity changes both the dosing and the price basis, and the 30% product usually carries a carrier that the 99% does not.
Quality and Documentation
Released on a batch certificate covering assay, species profile, peroxide value, heavy metals and microbiology.
Frequently Asked Questions
How is Ceramide Powder 99% quantified?
By HPLC against the specification figure of Ceramide 99.0%.
Which marker is the percentage based on?
The declared figure is Ceramide 99.0%, measured by HPLC; the marker basis is recorded on the batch certificate.
How do you control related substances?
Related substances are integrated on the same HPLC run used for the Ceramide 99.0% assay.
How does the material behave in your process?
It is supplied as White to off-white powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
What do you declare for moisture and ash?
Both are released against the limits on the approved specification; the measured result for your lot appears on its COA.
How is the material shipped?
Air and sea freight are both arranged, with the mode chosen against volume, destination and required date. Documents and the HS code are issued with the shipping instructions.
Which documents come with the shipment?
Batch COA, specification sheet, agreed third-party testing where required, commercial invoice, packing list, certificate of origin and transport documents. The exact set is confirmed against the product and destination market.
Can I review the COA before I pay?
Yes. Request the current or representative COA and check identity, method, limits and results before approving the purchase order.
