Leupeptin, scientifically known as N-acetyl-Leu-Leu-Arg-al, is a remarkable compound with the molecular formula C20H38N6O4 and a molecular weight of 426.55400. Identified by its CAS number 24365-47-7, this white powder boasts a density of 1.21 g/cm3 and an index of refraction of 1.557. Its unique chemical structure and properties make it a standout in various industries, particularly in cosmetics and biochemical research. This article explores its characteristics, applications, and why sourcing from a trusted leupeptin supplier in China can be a game-changer for businesses worldwide.

Chemical Composition and Physical Properties

Leupeptin is a tripeptide derivative, featuring a combination of leucine and arginine units, capped with an acetyl group and an aldehyde functionality (Ac-Leu-Leu-Arg-H). Its synonyms, such as acetyl-Leu-Leu-Arg-al and Acetyllaevulinsaeure, reflect its complex yet fascinating structure. With an assay purity of ≥95.0%, leupeptin appears as a fine white powder, making it easy to handle and incorporate into various formulations. Its physical stability is enhanced when stored in a cool, ventilated environment, typically packaged in 25 kg drums or customized according to client needs. These properties ensure that leupeptin remains consistent in quality, a key factor when considering a leupeptin manufacturer in China for bulk supply.

Applications of Leupeptin in Cosmetics

One of the most prominent uses of leupeptin lies in the cosmetic industry. This compound is celebrated for its ability to inhibit proteases—enzymes that break down proteins. In skincare formulations, leupeptin helps preserve the integrity of proteins in the skin, potentially reducing signs of aging such as wrinkles and fine lines. Its role as a protease inhibitor can enhance the stability of cosmetic products, ensuring they remain effective over time. This makes leupeptin a valuable ingredient in anti-aging creams, serums, and other beauty products aimed at maintaining youthful skin. Beyond its anti-aging benefits, leupeptin’s application in cosmetics extends to protecting sensitive skin by minimizing protein degradation caused by environmental stressors. As the demand for high-performance skincare grows, sourcing from a reliable leupeptin supplier in China becomes essential to meet market needs with consistent quality and competitive pricing.

Why Choose a Leupeptin Manufacturer in China?

China has emerged as a global hub for chemical manufacturing, and leupeptin is no exception. Manufacturers in China offer several advantages, including advanced production technologies, cost-effective pricing, and the ability to scale production from small batches to large volumes. A reputable leupeptin manufacturer in China ensures that the product meets stringent quality standards, with assays of ≥95.0%, making it suitable for cosmetic applications. Additionally, the flexibility to customize packaging—whether in 25 kg drums or tailored solutions—caters to diverse client requirements. The country’s robust supply chain and logistics infrastructure also facilitate timely delivery, a critical factor for businesses relying on steady raw material supplies. By partnering with an experienced manufacturer, companies can secure high-quality leupeptin while optimizing their production costs, giving them a competitive edge in the global market.

Sourcing High-Quality Leupeptin: Key Considerations

When selecting a supplier, quality assurance is paramount. Leupeptin’s efficacy in cosmetic applications depends on its purity and stability, so partnering with a supplier who conducts rigorous testing is crucial. Look for suppliers offering detailed specifications, such as density (1.21 g/cm3), molecular weight (426.55400), and refractive index (1.557), to ensure the product aligns with your needs. Storage conditions also play a role—keeping leupeptin in a cool, ventilated place preserves its integrity, a detail that top suppliers emphasize. Another consideration is the supplier’s ability to provide consistent supply. A dependable leupeptin supplier in China will have the capacity to deliver quantities ranging from small research batches to industrial-scale orders, all while maintaining high standards. This reliability is vital for cosmetic manufacturers aiming to launch products without delays or quality compromises.

The Science Behind Leupeptin’s Effectiveness

Leupeptin’s prowess as a protease inhibitor stems from its chemical structure, particularly the aldehyde group that interacts with enzyme active sites. This interaction prevents proteases from cleaving peptide bonds, a process that can degrade essential proteins in skin cells. In cosmetics, this translates to longer-lasting formulations and enhanced skin protection. For companies seeking to innovate in the beauty industry, collaborating with a knowledgeable leupeptin manufacturer in China can provide access to this cutting-edge ingredient at scale.
