25 Feb 2010 --- As a major international player within the hydrolyzed collagen industry, Rousselot produces and markets its hydrolyzed collagens to the health and nutricosmetic industries. The Group announces a new Peptan Cosmetic range intended for cosmetic applications. Supported by recent studies, Rousselot is launching PeptanTM SR marine (Skin Regeneration) and Peptan MR marine (Moisture Retention), topical versions of the Rousselot nutricosmetic active principle.

Caroline Nègre, RHC Marketing Manager, says “The results of in-vitro studies which we have conducted using specific grades of hydrolyzed collagen have been particularly positive. We are very proud to be able to offer the cosmetics industry our expertise in all matters collagen-related and to be able to provide ingredients of proven efficacy which are readily incorporated in anti-aging and personal hygiene applications.”

New active ingredients beneficial to the skin

The new peptide active ingredient of marine origin – Peptan SR marine – actually boosts fibroblast proliferation and promotes the synthesis of collagen; the structural organization of the dermis is thus preserved:
• Tested on a culture of fibroblasts, PeptanTM SR marine utilized in a dosage of 0.1mg/ml for 24 hours induces a significant increase of 18% in the proliferation of fibroblasts by comparison with an untreated control (p=0.016). *
• Tested on a culture of fibroblasts, PeptanTM SR marine utilized in a dosage of 0.01mg/ml for 2 days induces a significant increase of 22.5% in the synthesis of collagen by comparison with a control treated with BSA (p<0.05). **

Used in a concentration of 1% in cosmetic formulations, PeptanTM SR marine is an activator of the synthesis of collagen by fibroblasts. It is thus capable of restoring the three-dimensional structure of the dermis, giving it cohesion and tonicity. Its action on the extracellular matrix of the dermis thus combats the loss of firmness which in time leads to wrinkles. Peptan SR marine has also demonstrated an antioxidant effect. .

Peptan MR marine is a natural marine biopolymer with known film-forming properties, which helps to maintain the moisture balance of the skin and provides it with NMF-specific amino acids.

Ease of incorporation into topical formulations, even non-perfumed ones
Peptan Cosmetic is a range of type-1 natural peptides of collagen. Exceptionally versatile, they offer a unique combination of functional and sensory advantages and enable formulators to design innovative and top of the range solutions. The Peptan Cosmetic range, which is available in powder form, contains no preservatives. Having no odor, it is very easily incorporated into non-perfumed formulations.

Rousselot at last highlight the potential synergies between the nutricosmetic and topical Peptan ranges and their complementary capacity to improve the health and beauty of the skin. Peptan Beauty products for nutricosmetic applications have demonstrated their moisturizing and anti-aging efficacy in two clinical studies.
