Palmitoyl Grape Seed Extract: properties, uses, pros, cons, safety

Palmitoyl Grape Seed Extract is a chemical compound of natural origin.

The name describes the structure of the molecule

• "Palmitoyl" refers to the derivative of palmitic acid, a common saturated fatty acid. It indicates that a molecule of palmitic acid has been bound to another molecule through an ester linkage.
• "Grape Seed" refers to the seeds of grapes, from which oils and other compounds can be extracted.
• "Extract" indicates that the product is a substance obtained by extracting desired components from grape seeds, usually through processes like infusion, decoction, or percolation.

Description of raw materials used in production and their funcions

• Grape Seed Extract. Derived from the ground-up seeds of red wine grapes, this extract is known for its high antioxidant content, especially proanthocyanidins.
• Palmitic Acid. A common saturated fatty acid found in fats and waxes, often derived from both animal and plant oils.

Step-by-step summary of industrial extraction process

• Grapes seeds are separated from the fruit pulp and then undergo a cold pressing or solvent extraction method to extract the beneficial compounds.
• The grape seed extract is then chemically bound to palmitic acid through an esterification process. This involves reacting the grape seed extract's hydroxyl groups with palmitic acid in the presence of a catalyst.
• The resultant palmitoyl grape seed extract is purified to eliminate unwanted residues and impurities, commonly using filtration or chromatography.

What it is for and where

Cosmetics

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.

Commercial Applications

Cosmetics and skincare. Used as an anti-aging ingredient in skin products to leverage its antioxidant properties.

Anti-wrinkle products. The extract might help reduce the appearance of wrinkles and improve skin texture.

Serums and lotions. Can be included in formulas for its ability to better penetrate the skin and offer anti-aging benefits.

Medical Applications

Skin protection. The antioxidants in grape seed extract can help protect skin from free radical damage and premature aging.

Potential wound healing. While research is limited, there are indications it might aid in skin repair.
