PLEUROTUS/ROSA CANINA FERMENT EXTRACT.

Valuable

A biotechnologically advanced ingredient, PLEUROTUS/ROSA CANINA FERMENT EXTRACT combines the beneficial compounds of oyster mushroom (Pleurotus) and rosehip (Rosa Canina) via a fermentation process. This method significantly enhances the bioavailability and potency of their natural skin-active components, delivering amplified antioxidant, soothing, and conditioning benefits.

Science

Mechanism of Action

Fermentation transforms and concentrates the intrinsic bioactives of Pleurotus and Rosa Canina. This process yields smaller, more absorbable molecules and increases the content of free phenolic hydroxyl groups, boosting antioxidant and skin-enhancing capabilities. Pleurotus extracts are rich in beta-glucans, proteins, and polyphenols, providing robust antioxidant, anti-inflammatory, and immunomodulatory support. Rosa Canina contributes vitamin C and additional polyphenols, known for skin conditioning, astringent, and pigment-inhibiting effects. Together, the ferment works to protect against oxidative stress, calm irritation, and promote a more even, healthy complexion.

While specific data for the ferment extract is unavailable, related Rosa Canina Fruit Extract and Flower Extract have concentration restrictions in dusting applications. The Cosmetic Ingredient Review (CIR) Expert Panel advises a maximum of 0.01% for these derivatives in powders, dusting, talcum, and perfumes, to ensure non-irritating and non-sensitizing formulations. Formulators should be mindful of these thresholds when incorporating this ferment into powdered or sprayable products.

Stability

Optimal stability for related Pleurotus pigments has been observed at pH 7.0. As a general principle, fermentation extracts are often sensitive to extreme pH levels, and strong oxidizing or reducing agents should be avoided to maintain ingredient integrity and efficacy.

Sensitization risk Moderate

The CIR Expert Panel concluded that various Rosa canina-derived ingredients are safe for cosmetic use when formulated to be non-irritating and non-sensitizing. Specific maximum concentrations include 0.25% for Rosa Canina Fruit Extract in pump hair sprays and 0.01% in powders/perfumes. While no direct safety assessment exists for the combined ferment extract, formulators should be aware of potential allergens (e.g., benzyl alcohol, eugenol) present in related Rosa damascena species, which may require labeling if exceeding specific thresholds (e.g., 0.001% in leave-on products).
