Hydrolyzed Collagen

What Is It?

Hydrolyzed Collagen is a mixture of small peptides obtained from through the hydrolysis of collagen. In cosmetics and personal care products, Hydrolyzed Collagen is used primarily in hair preparations and skin care products, but can also be found in makeup, shampoos and bath products. Hydrolyzed Collagen may also be used in hair dyes.

Why Is It Used?

When used in hair preparations, Hydrolyzed Collagen enhances the appearance and feel of hair by increasing hair body, suppleness or sheen. It may also improve the texture of hair that has been damaged physically or by excessive treatment. Hydrolyzed Collagen used in skin-care products enhances the appearance of dry or damaged skin by reducing flaking and restoring suppleness.

Scientific Facts

Hydrolyzed Collagen generally is adsorbed on hair, increasing tensile strength and elongation. It is also used in soaps to impart a soft texture to skin. Hydrolyzed Collagen generally refers to enzymatically or chemically processed Collagen.

Safety Information

The safety of Hydrolyzed Collagen has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that Hydrolyzed Collagen was safe when used as a cosmetic ingredient. In 2004, as part of the scheduled re-evaluation of ingredients, the CIR Expert Panel considered available new data on this ingredient and reaffirmed the above conclusion.

CIR Safety Review: Hydrolyzed Collagen was practically nontoxic when administered orally or dermally in acute toxicity studies. This ingredient was minimally irritating to the eyes and skin when tested undiluted. Longer-term dermal studies on two cosmetic formulations containing 2% Hydrolyzed Collagen were negative for systemic toxicity. Hydrolyzed Collagen was nonsensitizing.

In clinical studies, Hydrolyzed Collagen produced no skin irritation, sensitization, or indication of phototoxicity. On the basis of the available data, the CIR Expert Panel concluded that Hydrolyzed Collagen was safe as a cosmetic ingredient.

The use of Hydrolyzed Collagen in cosmetic products is allowed in Europe according to the general provisions of the Cosmetics Regulation of the European Union. Ingredients of animal origin must comply with European Union animal by-products regulations.

More Scientific Information

Hydrolyzed Collagen is a collagen hydrolysate derived from acid, enzyme or other method of hydrolysis. It consists of water-soluble peptides of various molecular weights. These peptides are rich in the amino acids found in Collagen, including L-glycine, L-proline and L-hydroxyproline.

Nutritional supplements containing Hydrolyzed Collagen are marketed for bone and joint-health purposes. Hydrolyzed Collagen and gelatin hydrolysates are similar. Hydrolyzed Collagen is used as a conditioner or moisturizer in cosmetic products.
