Description

Acetyl Tetrapeptide-2 Acetate is a synthetic peptide used in cosmetic formulations, known for its potential to improve skin firmness and reduce signs of aging. This peptide is often included in products designed to promote skin rejuvenation and enhance overall skin texture.

Chemical Composition and Structure

Structure: Acetyl Tetrapeptide-2 Acetate is composed of a sequence of four amino acids, with an acetyl group attached to the N-terminus of the peptide chain and an acetate group that enhances its stability.
Chemical Formula: The acetylation and acetate modifications improve the peptide’s stability and bioavailability when applied topically.

Physical Properties

Appearance: Typically found as a white or off-white powder or in solution form, depending on the formulation.
Odor: Generally neutral, with potential slight variations based on other ingredients in the formulation.

Production Process

Synthesis: Created through solid-phase peptide synthesis (SPPS), which involves assembling the peptide chain amino acid by amino acid.
Purification: Following synthesis, the peptide is purified using techniques such as high-performance liquid chromatography (HPLC) to ensure purity and effectiveness.
Formulation: The purified peptide is incorporated into cosmetic products, ensuring its stability and effectiveness in various formulations.

Applications

Skin Care: Used in anti-aging serums, creams, and lotions to support skin firmness and elasticity. Ideal for products aimed at reducing fine lines and improving skin texture.
Cosmetics: Included in formulations to enhance skin hydration, elasticity, and overall appearance.

Cosmetic Benefits

Anti-Aging: Supports collagen production and improves skin elasticity, reducing the appearance of wrinkles and fine lines.
Firming: Enhances skin firmness, contributing to a more youthful and toned appearance.
Hydrating: Improves the skin’s ability to retain moisture, supporting overall skin hydration and barrier function.

Safety

This ingredient is generally regarded as safe for use in cosmetics and personal care products when used as directed. Individuals with allergies to peptides or those with very sensitive skin should use caution.

Environmental and Safety Considerations

Sustainability: As a synthetic peptide, it does not directly impact natural resources and is produced with controlled environmental considerations.
Regulation: Acetyl Tetrapeptide-2 Acetate is regulated by cosmetic safety standards to ensure it is safe for topical use.

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.
