Description

Acetyl Tetrapeptide-17 is a synthetic peptide used in cosmetic formulations for its skin-rejuvenating and anti-aging benefits. This peptide helps to improve skin texture, reduce the appearance of fine lines and wrinkles, and enhance overall skin elasticity and firmness.

Chemical Composition and Structure

Structure: Acetyl Tetrapeptide-17 is composed of a sequence of four amino acids with an acetyl group attached at the N-terminal end. This structure is designed to optimize the peptide's effectiveness and stability in cosmetic formulations.
Chemical Formula: The formula includes the amino acid sequence and the acetyl modification necessary for its function in skincare products.

Physical Properties

Appearance: Typically appears as a white or off-white powder, or it may be found in a liquid form depending on the formulation.
Odor: Generally has a neutral or minimal odor, which does not influence the fragrance of the final cosmetic product.

Production Process

Synthesis: Acetyl Tetrapeptide-17 is synthesized using solid-phase peptide synthesis (SPPS). This method allows for precise control over the sequence of amino acids in the peptide chain.
Purification: After synthesis, the peptide undergoes purification using high-performance liquid chromatography (HPLC) to ensure it meets purity standards.
Formulation: The purified peptide is then incorporated into various cosmetic products, ensuring it remains stable and effective in the final formulation.

Applications

Skincare: Commonly used in anti-aging creams, serums, and lotions. It helps to reduce the appearance of wrinkles and fine lines and improves skin firmness and elasticity.
Cosmetics: Used in formulations designed to enhance skin texture and tone, providing a smoother and more youthful appearance.

Cosmetic Benefits

Anti-Aging: Stimulates collagen production, improving skin firmness and reducing the visibility of wrinkles and fine lines.
Skin Elasticity: Enhances skin elasticity, contributing to a more youthful and supple appearance.
Texture Improvement: Helps to smooth and even out skin texture, making the skin look more radiant and healthy.

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 conduct a patch test before full application.

Environmental and Safety Considerations

Sustainability: As a synthetic peptide, it has a relatively low environmental impact compared to natural extracts.
Regulation: Adheres to cosmetic safety regulations to ensure 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.
