Description

n-Stearoyl-Seryl-Proline Ethyl Ester is a synthetic lipopeptide derivative, specifically engineered to combine the structural benefits of a long-chain fatty acid with a bioactive peptide sequence. This molecular design is crucial for enhancing skin penetration and stability in advanced cosmetic and pharmaceutical formulations. It is primarily sought by R&D and production teams in the cosmeceutical, dermatological, and high-performance personal care industries for developing next-generation anti-aging and skin-repair products.

Application

• Cosmeceutical Actives: A key functional ingredient in anti-wrinkle, firming, and anti-aging serums and creams, where it supports collagen synthesis and skin barrier function.
• Dermatological Preparations: Used in topical formulations aimed at skin repair, scar reduction, and improving skin elasticity.
• Advanced Skincare: Incorporated into moisturizers and lotions for its emollient properties and ability to enhance the delivery of other active compounds.
• Biochemical Research: Serves as a standard or intermediate in studies focusing on peptide-lipid conjugates, enzyme inhibition, and signal transduction pathways related to skin biology.
• Hair Care Products: Formulated into conditioners and treatments to improve hair strength and scalp health.

Quality Control

Our n-Stearoyl-Seryl-Proline Ethyl Ester is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation, to ensure it meets stringent specifications for cosmetic and research applications. Certificates of Analysis (COA) detailing all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption and degradation.
