Description

Acetyl Tetrapeptide-118 is a synthetic peptide designed for use in cosmetic formulations, particularly in anti-aging products. It is known for its potential to enhance skin firmness and elasticity, contributing to a more youthful appearance.

Chemical Composition and Structure

Structure: Acetyl Tetrapeptide-118 consists of a sequence of four amino acids with an acetyl group attached to the N-terminus of the peptide chain. This modification enhances the peptide's stability and absorption into the skin.
Chemical Formula: The acetylation of the peptide improves its interaction with skin cells and increases its efficacy in topical applications.

Physical Properties

Appearance: Typically found as a white or off-white powder or as a clear, colorless solution in its liquid form.
Odor: Usually neutral, or slightly influenced by other ingredients in the formulation.

Production Process

Synthesis: Produced through solid-phase peptide synthesis (SPPS), a method that builds the peptide chain one amino acid at a time.
Purification: After synthesis, the peptide is purified using high-performance liquid chromatography (HPLC) to ensure it meets quality standards and is free from contaminants.
Formulation: The purified peptide is then incorporated into cosmetic formulations, where it maintains stability and effectiveness.

Applications

Skin Care: Used in serums, creams, and lotions to improve skin texture and elasticity. Commonly found in products targeting mature skin, sensitive areas, and overall skin rejuvenation.
Cosmetics: Included in anti-aging and moisturizing products to enhance skin firmness and moisture levels.

Cosmetic Benefits

Anti-Aging: Helps reduce the appearance of fine lines and wrinkles by supporting collagen synthesis and skin elasticity.
Firming: Enhances skin firmness and elasticity, contributing to a more youthful appearance.
Moisturizing: Improves the skin's ability to retain moisture and supports the skin barrier function.

Safety

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

Environmental and Safety Considerations

Sustainability: As a synthetic ingredient, it does not have a direct impact on natural resources and can be produced with a controlled environmental impact.
Regulation: Acetyl Tetrapeptide-118 must comply with relevant cosmetic safety regulations, ensuring it is safe for topical use.
