Porous Particle Personal Care Composition for Long-Lasting Skin Blurring

The patent employs porous particles with high oil absorption values (50-1500 g/100g) as the core active ingredient. These porous structures absorb excess oil and sweat on the skin surface, maintaining the blurring effect by preventing oil breakdown of the optical matrix. The porosity enables continuous oil uptake throughout the wear period, resolving the contradiction between immediate blurring effect and duration.

The invention creates a composite system combining porous particles with film-forming polymers (acrylate, methacrylate, or urethane polymers). This composite structure forms a resilient optical matrix that maintains blurring properties while the porous component manages oil absorption. The combination synergistically provides both immediate visual effect and extended duration by preventing oil-induced breakdown.

The porous particles serve multiple functions simultaneously: they provide the primary blurring optical effect through light scattering, absorb excess oil and sweat to maintain effect duration, and contribute to the matte finish. This multi-functionality reduces the need for additional separate ingredients, managing composition complexity while achieving extended duration.

The patent optimizes specific parameters of the porous particles, particularly the oil absorption value (50-1500 g/100g) and particle size distribution, to achieve the desired performance. By carefully controlling these parameters, the invention achieves long-lasting effect with a relatively simple composition, as the optimized porous particles perform multiple functions within a narrow parameter range.
