Science
Mechanism of Action
This ingredient operates through a sophisticated blend of its natural components. Fatty acids and lecithin work synergistically to soften the skin, enhance moisture retention, and contribute antioxidant and anti-inflammatory effects; lecithin specifically aids in maintaining the skin's water balance. Vitamin A actively assists in reducing hyperpigmentation and brightening dark spots. A complex of vitamins (A, B, D) and minerals, including zinc, supports skin re-texturizing, intense nourishment, structural strengthening, and moisture lock-in. Proteins and vitamins facilitate the repair of damaged skin cells and accelerate cell turnover. Omega-3 and Omega-6 fatty acids provide profound hydration. The comprehensive lipid profile of egg yolk offers anti-inflammatory, antimicrobial, and acne-fighting actions, promotes healing, and acts as a penetration enhancer, thereby boosting skin elasticity, plumpness, and protection against environmental damage and bacteria. Phosvitin protein, upon enzymatic breakdown into peptides, functions as a potent antioxidant, antiviral, antibacterial, and metal-chelating agent. Furthermore, carotenoids like lutein and zeaxanthin serve as powerful antioxidants, effectively mitigating oxidative stress, combating visible signs of aging, and reversing environmental damage. Its inherent lipid content also endows it with beneficial emulsifying capabilities for formulations.

Stability
Dried egg yolk is susceptible to lipid peroxidation during processing and storage, which can compromise its protein structure and overall quality. Elevated temperatures, such as those during spray drying, may induce protein denaturation and reduce solubility. Degreasing treatments can similarly decrease solubility and water dispersibility due to protein unfolding. For optimal stability, dried egg yolks should be stored in a cool, dry place at room temperature; refrigeration is advised once opened. Reconstituted egg yolk should be utilized immediately or refrigerated for only short-term applications. The ingredient's intrinsic lipid content provides valuable emulsifying properties for formulations. Specialized encapsulation technologies, such as Ovasomes®, may be employed to effectively incorporate egg components into oil phases.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not explicitly assessed 'DRIED EGG YOLK' for cosmetic safety. While the European Commission's CosIng database lists it, a specific SCCS opinion is not available, and it references regulations on Category 1 and 2 animal materials without clarifying if this ingredient falls under those prohibitions. INCI Beauty categorizes it as 'Regulated' in Europe and the UK, though without further detail. It is important to note that the FDA's Generally Recognized As Safe (GRAS) status for certain dried egg yolk applications pertains to food safety and does not indicate its safety status as a cosmetic ingredient.
