Overview
Acetyl Tetrapeptide is a synthetic peptide composed of four amino acids, commonly used in the cosmetic industry for its anti-aging and skin-repairing properties. It is often marketed under trade names like Eyeliss and is a popular ingredient in high-end skincare products. The peptide works by stimulating collagen production and improving skin elasticity, making it a key component in formulations targeting wrinkles and puffiness. Research has shown that Acetyl Tetrapeptide can significantly reduce signs of aging, particularly around the eyes. Its small molecular size allows for better skin penetration, enhancing its efficacy. Due to its proven benefits, it is widely used in serums, creams, and other topical applications.
Physical and Chemical Properties
Acetyl Tetrapeptide is a white to off-white powder with a molecular weight of approximately 492.53 g/mol. It is soluble in water and alcohol, making it easy to incorporate into various cosmetic formulations. The peptide is stable under normal storage conditions but should be protected from extreme temperatures and moisture to maintain its efficacy. While the exact melting and boiling points are not widely documented, the peptide's stability in aqueous solutions makes it suitable for use in a range of pH levels. Its solubility and stability are key factors in its widespread use in skincare products.
Main Applications
Acetyl Tetrapeptide is primarily used in the cosmetic industry, particularly in anti-aging and skincare products. It is a common ingredient in eye serums, creams, and lotions aimed at reducing wrinkles, puffiness, and dark circles. The peptide's ability to stimulate collagen production and improve skin elasticity makes it a valuable addition to formulations targeting mature skin. Beyond skincare, Acetyl Tetrapeptide is also explored for its potential in medical applications, such as wound healing and tissue repair. However, its primary use remains in cosmetics, where it is celebrated for its non-invasive approach to skin rejuvenation.
Safety and Storage
Acetyl Tetrapeptide is generally considered safe for topical use, with minimal risk of irritation. However, a patch test is recommended for individuals with sensitive skin. The peptide should be stored in a cool, dry place, away from direct sunlight, to maintain its stability and efficacy. Manufacturers should ensure that the peptide is handled in accordance with good manufacturing practices (GMP) to prevent contamination. Proper labeling and storage conditions are essential to preserve the peptide's properties and ensure its safe use in cosmetic formulations.
B2B Procurement Guide
When procuring Acetyl Tetrapeptide, B2B buyers should prioritize suppliers who provide a Certificate of Analysis (COA) to verify purity and stability. The peptide's price can vary significantly based on purity, with higher grades costing upwards of $500 per gram. Buyers should also consider the supplier's reputation and compliance with regulatory standards. It is advisable to request samples for testing before large-scale purchases. Additionally, buyers should ensure that the peptide is packaged and shipped under conditions that preserve its stability, such as temperature-controlled environments.
