In the world of specialized cosmetic ingredients, few compounds are as fascinating as acetyl dipeptide 1 cetyl ester. As someone who frequently researches peptide-based formulations, I often find myself diving deep into the technical specifications of these raw materials. Understanding the core characteristics—specifically the molecular weight—is essential for anyone interested in how these What is Acetyl Dipeptide-1 Cetyl Ester? compounds interact with surface-le Acetyl dipeptide-1 cetyl ester - Descrizione vel applications.
What is Acetyl Dipeptide 1 Cetyl Ester?
At its most basic level, this ingredient is a synthetic peptide used in cosmetics designed for its unique soothing properties. Often referred to by the synonym "Calmosensine," this molecule is composed of two primary amino acids: tyrosine + arginine. By combining these into a dipeptide structure and stabilizing it with a cetyl ester, the Dec 8, 2025 — INCI name: Acetyl Dipeptide-1 Cetyl Ester. CAS number: 196604-48-5. Molecular structure: Dipeptide with cetyl ester. Appearance: White to cream resulting compound gains excellent oil-solubility, which is a significant advantage for topical formulations.
When I look at the molecular structure, I see a carefully engineered chain (Ac-Tyr-Arg-{Cetyl ester}). It is this specific arrangement that allows the peptide to function effectively as a messenger, promoting a sense of tranquility and comfort on the skin's surface.
Technical Specifications: The 603.84 Value
For those of us tracking the purity and identity of our supplies, the molecular weight is a constant, verifiable metric. Across various databases, including PubChem and technical data sheets, the Molecular Weight: 603.84 (often rounded to 603.8 g/mol or 603.8374) is the standard value associated with this compound.
Here is a quick breakdown of the technical data I typically review:
* Chemical Formula: C33H57N5O5
* Molecular Weight 603.8: This remains the consistent benchmark for high-purity samples.
* Appearance: Typically a white to off-white powder.
* Solubility: Highly oil-soluble, which facilitates better integration into serums and creams.
* CAS Number: 196604-48-5
One reason this ingredient is so fa Acetyl dipeptide-1 cetyl ester (Synonyms: Calmosensine) vored in modern formulations is its low molecular weight. In the study of peptide delivery, a lower mass generally correlates with better absorption profiles. The fact that the formula weight 603.8 allows for stable, effective performance makes it a staple in my personal collection of high-quality cosmetic ingredients.
My Experience with the Ingredient
When I first started sourcing acetyl dipeptide 1 cetyl ester, I was struck by the precision required in Acetyl dipeptide-1 cetyl ester | C33H57N5O5 - PubChem - NIH its handling. Because it is a lab-engineered peptide, the molecular weight 603.84 is a vital indicator of batch consistency. When I receive a new shipment, I verify that the document Acetyl dipeptide-1 cetyl ester is an oil-soluble anti-ageing messenger peptide that promotes visibly firmer skin. Learn more at Paula's Choice. ation lists the correct molecular weight: 603.8 to ensure I am using the authentic compound.
I have found that the 1 cetyl ester modification is what truly sets this apart from standard dipeptides. It acts as a delivery vehicle, ensuring that the acetyl dipeptide remains stable and functional. Whether you are looking at it from a chemical perspective or simply as a user of raw cosmetic materials, the molecular weight data serves as the primary "fingerprint" of the substance.
Final Thoughts on Purity and Standards
For enthusiasts who prioritize transparency, always look for suppliers who provide a Certificate of Analysis (COA) confirming the molecular weight 603.8374 and purity levels, which should ideally be ≥98%. By understanding the specific molecular structure and the role of the tyrosine + arginine sequence, you gain a much better appreciation for why this synthetic peptide used in cosmetics is so highly regarded for skin comfort and relaxation.
Ultimately, the technical consistency of this molecule—de ACETYL DIPEPTIDE-1 CETYL ESTER fined by its 603.8 g/mol mass—is what makes it a reliable choice for anyone interested in the science of high-performance cosmetic ingredients.
