Acetyl Tetrapeptide-2 is an acetylated four-amino-acid cosmetic peptide used in formulations positioned for firming, elasticity support and mature-skin care. The defined Ac-Lys-Asp-Val-Tyr sequence offers formulators a compact peptide active for premium serums, creams, neck products and multi-peptide systems.

Basic Product Information

Key Product Value
Defined reduced tripeptide structure. The γ-glutamyl linkage and cysteine thiol group give Glutathione its characteristic biochemical and formulation profile.
Antioxidant-system positioning. GSH is widely evaluated in antioxidant and redox-related systems.Performance in a finished product depends on
concentration, formula, processing,packaging and stability control.
Broad downstream compatibility. The material can support cosmetic, biochemical, analytical And nutritional projects when the correct grade and specification are selected.

Main Application Areas
Cosmetic and personal care formulations. For antioxidant-focused serums, creams, masks and other skin-care concepts. Formula stability, color, odor and compatibility should be evaluated in the complete system.
Biochemical and laboratory use. For redox studies, enzyme-related workflows, cell-free systems,standards and other biochemical applications requiring a known glutathione input.
Nutritional product development. For nutritional blends and ingredient systems where reduced glutathione is permitted and the selected grade meets local requirements.
Fine chemical and formulation research. For product development, analytical comparison and Process studies involving a sulfur-containing tripeptide building block.

Frequently Asked Questions

What should be confirmed before ordering? Confirm the exact product name, CAS number, molecular form, required quantity, purity target, packaging, destination, and document list. For modified or species-specific materials, also confirm the complete sequence and modification pattern.

Does 98% purity mean 98% active content? Not necessarily. Chromatographic purity is usually a relative peak-area result. Water, counter-ions, salts, and other non-volatile components may affect the weighed amount. Ask for the content basis when exact molar preparation is important.

Which documents are commonly available? A lot-specific Certificate of Analysis is the main document. Supporting chromatographic and mass data can be discussed, together with any additional test agreed before release.

Can the package size be customized? Yes, subject to material compatibility and production feasibility. Small research packs, multiple matched units, or larger research quantities can be reviewed during quotation.

How should a working concentration be selected? There is no single concentration suitable for every model. Researchers should begin with relevant published methods or prior internal data, then perform a range study with suitable controls.

How long can a prepared solution be kept? The answer depends on solvent, concentration, pH, temperature, light, container, and assay requirements. Use freshly prepared solution when possible or establish a validated holding period for the specific method.

Why is the lot certificate important? The certificate connects the physical material to its batch number, test results, product form, and storage statement. General website information cannot replace the delivered lot record.

Who is the intended customer? The material is intended for trained professionals in qualified laboratory, biotechnology, industrial research, academic, or contract research settings.

Research-Use Statement

This material is supplied solely for laboratory research and analytical work by trained professionals. It is not supplied for human or veterinary use, food use, household use, or diagnostic procedures. The purchaser is responsible for assessing suitability, reviewing the lot documents, establishing safe laboratory procedures, and following applicable institutional and local requirements.

Packaging, Storage and Use Statement

Commercial packaging is selected according to the product form and order quantity. Inner packaging, net weight, label language, shipping marks and customized configurations should be confirmed in the quotation.

Keep in the original tightly closed package in a cool, dry place, protected from light, moisture and air. After opening, reseal promptly and use clean handling procedures. Exact storage, shelf-life and retest instructions follow the label and batch documentation.
