In the cosmetics industry, silica is a familiar material. For a long time, it has been a staple in makeup and skincare formulations, valued for its light weight and versatility, serving essential functions such as oil control, improving skin feel, and enhancing texture.
However, when we shift our focus to the semiconductor field, silica takes on an entirely different role—as a “chip-grade” material. Only under conditions of extremely high purity and precise structural control can silica be applied in critical processes such as chip packaging and wafer polishing.
UNI-POWDER’s latest launch of chip-grade high-purity silica is based on a more refined preparation concept, introducing the high purity and structural control originally serving the semiconductor industry into cosmetics. It not only retains the traditional functions of silica, but also achieves a qualitative leap in purity, safety, smoothness, and flowability.
High Purity & Uniform Particle Size: Empowering Skin Feel and Stability
▶ Purity up to 99.99%
Advanced processing effectively minimizes heavy metals and impurity residues, enhancing formulation stability and ensuring a cleaner, purer skin feel.
▶ Precisely controlled, uniform particle size
Even particle distribution reduces powder friction and uneven stacking, delivering a significantly smoother texture that feels lightweight, silky, and non-drying upon application.
▶ Outstanding flowability
Maintains excellent dispersion and free-flowing properties during both formulation processing and application, resulting in a more even and natural finish.
Different Silica Morphologies, Different Applications
Silica comes in diverse morphologies—spherical, flaky, hollow, mesoporous, etc.—with each structure offering distinct functional characteristics.
· Spherical silica: Excellent flowability and low friction, commonly used to improve skin feel and enhance powder dispersibility.
· Hollow or lightweight silica: Light and airy, ideal for soft-focus effects and a weightless texture.
· Mesoporous silica: High specific surface area with pores that provide combined functions such as oil absorption, act as carriers, and light scattering.
Clearly, beyond purity, the functional performance of silica depends on multiple factors, including morphology and structure.
Mesoporous Structure: From Surface Area to Texture Control
UNI-POWDER chip-grade high-purity silica features a characteristic mesoporous structure. Compared with micropores and macropores, mesopores offer several advantages:
▶ High specific surface area
This structure provides more surface sites, enabling longer-lasting sebum absorption.
▶ Optimized optical properties
The regular mesoporous arrangement and excellent pore connectivity produce softer, more uniform light scattering, enhancing the powder’s soft-focus matte effect.
▶ Enhanced skin feel
The mesoporous structure creates “buffer spaces” between particles, reducing friction and making the powder glide more smoothly on the skin.
▶ Superior adsorption and carrying capacity
Its highly ordered cylindrical pores facilitate loading and release of sunscreen agents or actives, making it ideal for functional delivery applications.
UNI-POWDER chip-grade high-purity silica features high purity, uniform particle size distribution, a mesoporous structure, and H1-type hysteresis loop characteristics, achieving superior performance in skin feel, flowability, and optical effects compared with conventional silica.
