Description

Acetyl Tetrapeptide-11 is a synthetic peptide commonly used in cosmetic formulations for its anti-aging and skin-rejuvenating properties. It is known for its role in promoting cellular regeneration and improving skin texture.

Chemical Composition and Structure

Structure: Acetyl Tetrapeptide-11 is composed of a chain of four amino acids with an acetyl group attached at the N-terminal end, which enhances its stability and effectiveness in skincare products.
Chemical Formula: This peptide's formula combines the specific amino acid sequence with an acetyl group to optimize its skin benefits.

Physical Properties

Appearance: Available in white or off-white powder or liquid form, depending on the formulation.
Odor: Generally neutral or faint, which does not influence the overall fragrance of the cosmetic product.

Production Process

Synthesis: Created through solid-phase peptide synthesis (SPPS), allowing precise assembly of the peptide chain.
Purification: After synthesis, it is purified using high-performance liquid chromatography (HPLC) to ensure high purity and efficacy.
Formulation: Integrated into cosmetic products to maintain its effectiveness and stability.

Applications

Skincare: Utilized in anti-aging creams, serums, and lotions to enhance skin regeneration, improve texture, and reduce signs of aging.
Cosmetics: Included in products designed to revitalize the skin, contributing to a youthful and radiant appearance.

Cosmetic Benefits

Anti-Aging: Encourages the production of key skin proteins, potentially reducing the appearance of fine lines and wrinkles.
Skin Regeneration: Supports cellular renewal, leading to a more youthful and vibrant complexion.
Texture Improvement: Enhances the skin's texture, making it 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 allergies or sensitivities to peptides should review ingredient lists carefully.

Environmental and Safety Considerations

Sustainability: As a synthetic peptide, it typically has a lower environmental impact compared to natural extracts.
Regulation: Complies with 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.
