When exploring the world of advanced cosmetic ingredients, one often encounters a variety of specialized molecules. Among these, pentapeptide-3 stands out as a fascinating subject for those interested in the science of skincare formulations. As a user who frequently reviews high-end cosmetic actives, I have spent considerable time researching the specific identifiers and structural properties of this peptide to better understand its role in modern chemical synthesis.
Identifying the Molecule: Pentapeptide-3 CAS No.
For anyone involved in sourcing or analyzing raw materials, the CAS number is the most critical piece of Nanosome Palmitoyl Pentapeptide-3 documentation. It serves as a unique numerical identifier that removes ambiguity in scientific and commercial databases. When searching for this specific ingredient, you will frequently see the CAS Number 135679-88-8 associated with the sequence Gly-Pro-Arg-Pro-Ala-NH2 (often abbreviated as GPRPA-NH2).

While 135679-88-8 is the standard for the sequence mentioned above, some technical databases also reference CAS #: 725232-44-0 when discussing the synonym "Vialox." As a researcher, noticing these variations is part of the due diligence required when evaluating ingredient purity and origin. Whether you are dealing with a pentapeptide in powder form or a solution, always verify the documentation provided by the supplier.
Complexity and Variations: Pentapeptide vs. Palmitoyl Pentapeptide
It is easy for beginners to confuse pentapeptide-3 with other members of the peptide fami Pentapeptide-3 (Vialox) ly. A common point of confusion is the distinction between this molecule and Palmitoyl Pentapeptide-4 (often associated with CAS Number 214047-00-4).
While both are synthetic peptides used in topical applications, their chemical structures—and therefore their interactions—differ significantly. For instance, Matrixyl (Palmitoyl Pentapeptide-3) is a distinct complex that has gained historical fame in the industry for its role in supporting the structural integrity of the skin. Another related entry is Pentapeptide-4 (CAS No. 149128-48-3), which features a different amino acid composition, specifically lysine, serine, and Pentapeptide-3 - ExperChem threonine.
When looking at the broader landscape, you might encounter other identifiers like CAS. 64963-01-5 for pentapeptide-18, further highlighting why one must be precise with the Cas No when auditing a formulation.
My Personal Experience and Observations
In my ow Palmitoyl tripeptide-38 (CAS 1447824-23-8) n experiments with high-end cosmetic actives, I have found that the efficacy of these ingredients depends heavily on their delivery system. I have tested various iterations, including Nanosome Palmitoyl Pentapeptide-3, which utilizes advanced encapsulation technology to improve the stability of the molecule.
When evaluating these products, I look for:
* Purity Levels: High-quality providers usually offer 98% purity.
* Solubility: Understanding if the substance is lipophilic or hydrophilic is essential for proper emulsion.
* Documentation: Never rely on a "Cas No.: N/A" label when sourcing professional-grade materials. Always request a Certificate of A Cas No.: 725232-44-0. Synonym: Vialox. Application: cosmetics. Packaging Pentapeptide-3 reduces the depth of wrinkles caused by the contraction of nalysis (COA).
Navigating the Technical Landscape
Whether you are investigating Pentapeptide-3 CAS No. 135679-88-8 for its role in modulating skin appearance or comparing it to other 3-residue or pentapeptide structures, the goal is always to maintain clarity. The market is saturated with various catalog numbers—such as 27261—which often correspond to specific stock keeping units in laboratory databases rather th Anti aging efficacy and ingredients: palmitoyl pentapeptide an the chemical structure itself.
By maintaining a rigorous focus on the CAS registry and understanding the structural differences between a standard pentapeptide and its palmitoylated counterparts, you can better navigate the complex world of cosmetic chemistry. Always remember that these substances are for external cosmetic use only and should be handled with the respect due to any sophisticated chemical raw material.
