Description

Acetyl Tetrapeptide-15 is a synthetic peptide used in cosmetic formulations for its skin-enhancing and anti-aging properties. This peptide is designed to reduce the appearance of wrinkles and improve skin firmness, contributing to a younger-looking and smoother complexion.

Chemical Composition and Structure

Structure: Acetyl Tetrapeptide-15 is composed of a chain of four amino acids with an acetyl group attached to the N-terminal end. This structure allows the peptide to penetrate the skin effectively and provide its benefits.
Chemical Formula: The formula includes the amino acid sequence and the acetyl group, which enhance its efficacy and stability in cosmetic formulations.

Physical Properties

Appearance: Typically appears as a white or off-white powder or in liquid form, depending on the formulation.
Odor: Has a neutral or very faint odor that does not affect the fragrance of the final product.

Production Process

Synthesis: Acetyl Tetrapeptide-15 is synthesized using solid-phase peptide synthesis (SPPS), allowing for precise and controlled assembly of the peptide sequence.
Purification: After synthesis, the peptide is purified through high-performance liquid chromatography (HPLC) to ensure purity and efficacy.
Formulation: The purified peptide is incorporated into cosmetic products, maintaining its stability and activity in the final formulation.

Applications

Skincare: Used in anti-aging creams, serums, and lotions to improve skin appearance, reduce wrinkles, and increase elasticity.
Cosmetics: Found in products designed to enhance skin texture and provide a more even and radiant look.

Cosmetic Benefits

Anti-Aging: Stimulates collagen production and other skin proteins, reducing the visibility of wrinkles and improving firmness.
Skin Elasticity: Contributes to increased skin elasticity, making it firmer and more toned.
Texture Improvement: Enhances skin texture, making it appear smoother and more even.

Safety

This ingredient is generally regarded as safe for use in cosmetics and personal care products when used as directed. Individuals with sensitive skin or allergies to peptides should exercise caution and perform a preliminary test on a small area of skin.

Environmental and Safety Considerations

Sustainability: As a synthetic peptide, it has minimal environmental impact compared to natural plant extracts.
Regulation: Complies with cosmetic safety regulations, ensuring safe use in topical applications.

INCI Functions:


Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
