LYSOLECITHIN.

Valuable CAS 85711-58-6 / SURFACTANT - EMULSIFYING

Lysolecithin is a versatile phospholipid-derived ingredient that functions primarily as an emulsifier, essential for creating stable and aesthetically pleasing skincare formulations. Beyond its textural contributions, it provides significant skin benefits, including enhanced hydration, visible barrier repair, and improved delivery of active ingredients.

Science

Mechanism of Action

Lysolecithin acts fundamentally as an emulsifier, enabling the seamless blend of oil and water-based components to achieve uniform, stable, and easily spreadable formulations. On the skin, it operates as a conditioning agent, offering lightweight, non-greasy hydration and supporting the visible restoration of the skin's crucial moisture barrier. Furthermore, lysolecithin facilitates advanced ingredient delivery by interacting with the skin's uppermost layers, aiding in the release and enhanced absorption of active compounds. It also possesses mild cleansing capabilities, assisting in the emulsification of impurities for effective rinsing.

Key findings

  1. 01 Studies indicate that at low concentrations, specifically within the range of 0.05% to 0.075%, lysolecithin positively impacts skin health. Its application demonstrably enhances skin hydration through the prevention of transepidermal water loss and aids in the visible repair of the skin's protective barrier. Importantly, lysolecithin also improves the penetration and absorption of other active ingredients into the skin.

Sensitization risk Low

The 2015 Cosmetic Ingredient Review (CIR) Expert Panel affirmed lysolecithin and other phosphoglycerides as safe for their intended uses and concentrations in cosmetic products, with the highest reported maximum use concentration at 0.2%. Formulators must exercise caution when combining lysolecithin with other ingredients whose safety profile is contingent on minimal dermal absorption, as lysolecithin possesses penetration-enhancing properties. Furthermore, formulations must meticulously avoid conditions conducive to the formation of N-nitroso compounds.
