Used in cosmetic formulations for its skin-conditioning properties, this phospholipid helps improve skin hydration and barrier function. It is commonly found in anti-aging creams, serums, and moisturizers due to its ability to enhance lipid bilayer structure in the skin. Also utilized in liposomal delivery systems to encapsulate active ingredients, improving their penetration and stability. In pharmaceuticals, it supports drug delivery efficiency by increasing bioavailability of compounds through membrane fusion or cellular uptake enhancement.

In the food industry, it acts as a natural emulsifier, aiding in the stabilization of emulsions in products like mayonnaise, sauces, and dairy items to prevent separation. Additionally, it is incorporated into nutritional supplements for liver health and nervous system support, due to its role in cell membrane function and neuron formation.

Derived from egg yolk via transphosphatidylation, its natural origin makes it suitable for use in mild and sensitive skin products, as well as clean-label food and supplement formulations.
