Analysis of Core Cosmetic-Grade Silica Models: Application Guide for SIPERNAT and AEROSIL Series
In summary, the SIPERNAT and AEROSIL series of cosmetic-grade silica form a differentiated functional matrix: the SIPERNAT series focuses on eco-friendly exfoliation replacement and gentle skin feel regulation, while the AEROSIL series centers on rheology control and anti-caking enhancement.
In the cosmetic formulation system, silica, as a multi-functional auxiliary material, has become a core component of color cosmetics and skin care products due to its excellent performance in skin feel regulation, stability enhancement and texture optimization. The following focuses on four core models—SIPERNAT 2200 PC, SIPERNAT 22 PC, AEROSIL R812, and AEROSIL R202, analyzing their professional value in the cosmetic field from the perspectives of product characteristics, formulation advantages and typical application scenarios.
SIPERNAT 2200 PC: The Preferred Eco-Friendly Exfoliating Particle
With the core advantage of porous structure with specific particle size distribution, SIPERNAT 2200 PC is an eco-friendly solution that can effectively replace polyethylene beads in exfoliating skin care products such as shower gels and body cleansers. Its porous structure combines gentle exfoliation and cleansing power, which can physically remove dead skin cells without damaging the skin barrier. Meanwhile, it is compatible with powder systems, which can improve the dispersion uniformity of particles in scrubs and avoid skin irritation caused by particle agglomeration during use, conforming to the development trend of green cosmetics.
SIPERNAT 22 PC: Dual-Effect Component for Gentle Exfoliation and Skin Feel Optimization
As an eco-friendly auxiliary material, SIPERNAT 22 PC can replace polyethylene beads in products like shower gels. Its fine particle size enables gentle exfoliation in exfoliating products, making it suitable for sensitive skin care formulations. It also has excellent dispersibility: in powder cosmetics such as loose powder and eyeshadow, it can improve fluidity and smooth skin feel while preventing caking; when added in small amounts to lotions, it can reduce greasiness and create a refreshing experience. Its neutral pH range of 6.0-8.0 further enhances formulation compatibility.
AEROSIL R812: Core Auxiliary for Rheology Regulation in Oil-Based Formulations
AEROSIL R812 has a large specific surface area of 230-290 m²/g and adopts HMDS hydrophobic modification technology. In the cosmetic field, it can effectively regulate the rheology of oil-based formulations such as nail polish and lip gloss, significantly improving anti-settling performance. Its excellent dispersibility and fluidity can enhance the fluidity and smooth skin feel of powder cosmetics like loose powder and pressed powder, serving as a high-efficiency flow agent for fine powder systems. Meanwhile, its strong hydrophobicity ensures excellent stability in oil-based systems, which can enhance the storage stability of lip gloss and nail polish and reduce stratification.
AEROSIL R202: High-Efficiency Rheology Modifier and Anti-Caking Agent
AEROSIL R202 takes PDMS modification as its core technology and acts as a high-efficiency rheology modifier and anti-caking agent in the cosmetic field. In powder products such as foundation and eyeshadow powder, it can effectively prevent particle settling, significantly improve fluidity and storage stability, and help create a smooth and dry skin feel. In cream cosmetics like lipsticks and blush creams, it can adjust product viscosity and enhance stability; its hydrophobic property can also improve the water resistance of systems such as sunscreen lotions, adapting to the formulation needs of multiple cosmetic categories.
In summary, the SIPERNAT and AEROSIL series of cosmetic-grade silica form a differentiated functional matrix: the SIPERNAT series focuses on eco-friendly exfoliation replacement and gentle skin feel regulation, while the AEROSIL series centers on rheology control and anti-caking enhancement. They fully cover multiple scenarios such as exfoliation, color cosmetics and skin care, providing professional support for green and high-performance cosmetic formulations.
