Applications of Silica Solutions in the Cosmetics Industry
For cosmetics, adding silica helps absorb moisture and oily components, keeping powders dry, preventing clumping, improving powder flowability, preventing moisture caking, and enhancing storage stability.
For foundations, setting powders, and other cosmetics, adding spherical silica effectively improves the flowability of powders and emulsions, enhancing skin feel and a soft-focus effect.
For ointments and other creams, adding silica can regulate the rheology of the paste, making it full and non-collapsed, and easy to extrude.
Furthermore, silica, with its excellent adsorption properties, can also be used as a carrier for active ingredients.
KosNature’s various silica grades comprehensively meet the above functions, offering a wide range of products to meet your needs and providing customization services.
Our silica features high whiteness, uniform particle size distribution, stable physicochemical properties, good compatibility with your cosmetics, and excellent anti-caking or anti-carrier properties.
Common Formulation Challenges
Many cosmetic formulations face challenges such as:
• Poor oil control and short wear time
• Heavy or greasy skin feel
• Weak soft-focus or blurring effect
• Poor compatibility in oil-based systems
• Instability in powder or dispersion systems
These issues directly affect product performance and user experience.
How We Solve These Challenges
We design material solutions that directly target formulation performance:
Oil Control
→ Silica (porous / spherical)
Soft Focus
→ Spherical silica
Texture Optimization
→ Silica + MgO
UV Protection / Functional
→ ZnO / TiO₂
Recommended Material System
Function | Material | Benefit |
Oil control | Silica | Absorb sebum |
Soft focus | Spherical silica | Blur effect |
UV protection | ZnO / TiO₂ | Protection |
Texture | Silica + MgO | Smooth feel |
