Navigating the Sh-Polypeptide-16, also known as "sh-polypeptide," is a modern cosmetic ingredient valued for its ability to promote skin hydration and elasticity. complex world of skincare formulation often leads to the INCI (International Nomenclature Cosmetic Ingredient) dictionary. As an enthusiast who spends considerable time researching the components behind top-tier cosmetic products, I have found that understanding the polypeptide INCI name is essential for anyon Polypeptide Enriched Media (with Product List) e looking to decipher ingredient labels beyond mere marketing claims.
What is a Polypeptide INCI Name?
The INCI name serves as the universal language for identifying ingredients globally. When you see a polypeptide listed, you are looking at a chain of amino acids. The way these are named follows strict regulatory conventions. For example, Polypeptide-1 is a synthetic peptide containing a specific sequence—153 amino acids—that has become a staple in modern formulations.
In my experience, the prefix "sh-" is a critical identifier. It stands for "synthetic human," indicating that the ingredient is a recombinant protein produced via fermentation, often in *E. coli* or *Pichia pastoris*. You will frequently encounter entries like SH-POLYPEPTIDE-29, sh-Polypeptide-22, and SH-POLYPEPTIDE-107 in professional-grade products. These are not random codes; they represent specific structural configurations designed for targeted performance.
Variations and Specific Entities
The diversity of these ingredients is vast. I have been particularly impressed by the evolution INCI Name,SH-POLYPEPTIDE-29. Description, sh-Polypeptide-29 is a single chain recombinant human peptide, produced by fermentation in E. coli.Read more of specialized compounds:

* Functional Peptides: Some ingredients are categorized by their specific activity. For instance, SH-POLYPEPTIDE-1 (often linked to A The brand says the conditioner is "made with Bio-Protein Care and infused with Glutamic Amino Serum, that helps restore damaged hair for Read more cidic Fibroblast Growth Factor) is widely recognized for its role in skin conditioning. Similarly, Sh-Polypeptide-16 is frequently sought after for its influence on hydration and elasticity.
Sh-polypeptide-7Beyond the Basics: Complex Naming
When evaluating a peptide name, one must look for the modifying groups. The industry uses specific rules; for example, Acetyl dipeptide-1 cetyl ester or Acetyl Dipeptide-31 Amide follow the nomenclature where the parent peptide is combined with its modifying group.
I recently analyzed the INCI English name for a newer material: *beta-Alanyl HydroxyprolyIdiaminobutyroyI*. While it sounds like a mouthful, it represents the precision of modern synthesis. Other entries, like Pisum Sativum (Pea) Peptide, show that natural extracts are also being standardized under these rigorous naming systems to ensure transparency.
Why This Matters for Your Routine
Whether you are looking at SH-POLYPEPTIDE-7 for its humectant properties or investigating INCI Name: sh-Polypeptide-50 (often associated with pure elastin materials), knowing the name helps you verify what is actually in your bottle.
I’ve found that even niche ingredients like Creapep® Arginine/Lysine Polypeptide offer fascinating insights into stability and penetration. If you see products labeled with SH-POLYPEPTIDE-1 NONAPEPTIDE-29 or those using Polypeptide Enriched Media, you are witnessing the intersection of peptide science and cosmetic chemistry.
By familiarizing yourself with these designations—from Sh-Polypeptide-3 to SH-POLYPEPTIDE-45—you move from being a passive consumer to an informed enthusiast, capable of distinguishing between high-performance biotechnology and basic formulations. Always remember, the POLYPEPTIDE label is your gateway to understanding the structural integrity and intended function of your favorite skincare products.
