What is porcine dermal ECM collagen, and is a quotation that says only Collagen the same purchase? It is not. Porcine Dermal ECM Collagen is a named cosmetic grade: a freeze-dried, multi-component protein complex from porcine dermis. Use this page to decide whether the offer in front of you is that grade. Then ask the supplier for the current specification and for a sample of the same trade name.
What a buyer has to identify
The useful comparison is between two lines on a quotation. One line names Porcine Dermal ECM Collagen. Another line says Collagen, sometimes with a porcine source and sometimes without one. Those lines can share an INCI word and still refer to different lots. Decide whether the offer names this grade’s trade name, tissue, and full INCI declaration.
What the public page says this grade is
The public product page uses the trade name Porcine Dermal ECM Collagen and names Green Stone Swiss as the supplier. It describes a freeze-dried cosmetic protein complex prepared from porcine dermis. The process words on that page are high hydrostatic pressure decellularization, followed by extraction, purification, and lyophilization. The source line reads Sus scrofa domestica dermis. The product-type line calls it a porcine dermal ECM collagen complex and a skin-conditioning protein matrix.
The same page lists the physical form as a white to pale yellow solid, or a lyophilized powder, and the grade label as Cosmetic Grade. It prints CAS as N/A. It also says that images and information are for reference only and that the actual product may vary. Treat those sentences as the public description you are matching. The specification you request is the document that identifies the lot you will receive.
How this grade sits beside the INCI name Collagen
The public page names Collagen as the principal INCI. It also says the grade is a tissue-derived mixture and a multi-component protein complex, rather than a single molecule. Ordering Collagen by that INCI name alone leaves the trade name, the tissue, and the rest of the declaration undecided. Ask the supplier to put all three on the current specification before you accept the lot as this grade.
The accompanying names printed on the page are Collagen Amino Acids, Keratin Amino Acids, Elastin, Fibronectin, Sodium Hyaluronate, Sodium Chondroitin Sulfate, and Sodium Dermatan Sulfate. The description and the specification block print this same set of names in different orders. Ask which order is on the current specification, and use that order in the sample request.
The page states that, according to CosIng, Collagen functions as a hair-conditioning, moisturising, and skin-conditioning agent. That sentence cites function vocabulary for the INCI name Collagen. It tells you how the inventory names that INCI. It still has to be read together with the commercial mixture on the specification, and it is not a finished-product claim.
The page positions the material as a leave-on skin-conditioning protein in creams, essences, serums, and masks. Read that as the application language attached to this grade. It shows where a formulator might trial it. It is not evidence for a finished formula. Name the intended base when you ask the supplier about the sample.
Which inquiry to send next
- A different collagen class: A hydrolyzed collagen peptide, and a material offered as atelocollagen or soluble collagen, each need their own sample request. If the quotation uses those words, decide which collagen sample to request and send that request for the label on the quotation.
- The file set for this grade: When the trade name matches, the species, tissue, INCI order, and batch documents still have to match the quotation. Review the files to check before sampling an animal-origin ECM collagen complex and include that file request in the same inquiry.
- The first trial: Dissolution, pH, temperature, and compatibility remain questions for the current TDS. Send the questions to confirm before a porcine dermal ECM collagen trial and ask the supplier to answer them in writing.
- Numbers and quality phrases on the web page: The public page includes language on protein content, residual DNA, use level, pH, addition temperature, and GMP-aligned quality control. The same page says the information is for reference only and that assay values such as protein content are confirmed on the batch COA. Ask for that COA with the sample. Those web figures and that quality phrase stay off the specification until the supplier’s document states them.
Next step
Send the supplier one inquiry for this trade name. Ask for the current specification with the species, tissue, and full INCI declaration marked, and ask for a sample of that same grade. Request the sample when the specification and the quotation name the same grade. Keep the returned document with the quotation so the later file check and trial questions use it too.
