L'Oréal Paris Infallible 24H Fresh Wear Soft Matte Foundation is formulated with a combination of synthetic polymer technology, silicone-based compounds, and various organic pigments, designed to provide extended wear and a matte finish. The primary active ingredients include water (aqua), dimethicone, cyclopentasiloxane, and various surfactants that function to enhance the product's textural and aesthetic qualities. Water acts as a solvent and delivery medium, contributing approximately 30-40% to the formulation's composition. Dimethicone and cyclopentasiloxane, both of which are cyclic siloxanes, enhance spreadability and provide a smooth application due to their low surface tension and non-occlusive properties. The use of these siloxanes also allows for a breathable finish that can minimize the perception of heaviness on the skin. The foundation includes a blend of pigments such as iron oxides (CI 77491, CI 77492, CI 77499), which provide opacity and color stability. These iron oxides are known for their stability and resistance to environmental factors, such as UV exposure, ensuring that the product maintains its color integrity throughout wear. The product maintains a pH around 5.0 to 6.0, which is close to that of natural skin, thus minimizing potential irritation. In terms of viscosity, the formula is engineered to be fluid, enabling ease of application with various tools.
