Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

Specification of Cosmetic Raw Material SiO2 Fumed Silica

Fumed silica, known as SiO2, is a key ingredient in many cosmetic products. It comes from vaporizing silicon tetrachloride at high temperatures. This process creates very fine particles. These particles form aggregates with high surface area. This structure gives fumed silica its useful properties.

Cosmetic formulators use fumed silica primarily as a thickener. It helps control the texture of creams, lotions, and gels. It prevents liquid components from separating. This improves product stability. It also acts as an anti-caking agent. It keeps powders flowing freely in foundations and blushes. This stops them from clumping together.

The small particle size is crucial. Typical particles range from 5 to 50 nanometers. This tiny size contributes to its large surface area. Surface area often measures between 50 and 400 square meters per gram. Higher surface area generally means better thickening power. It also impacts how the powder feels. Fine particles give a smoother, silkier touch to the skin.

Another important property is oil absorption. This tells us how much oil the silica can take up. Higher oil absorption helps mattify the skin. It reduces shine in makeup and skincare products. It also helps suspend pigments evenly.

Fumed silica comes in two main types: hydrophilic and hydrophobic. Hydrophilic silica attracts water. It works well in water-based formulas. Hydrophobic silica repels water. It performs better in oil-based systems or anhydrous products. Choosing the right type depends on the formula’s base.

It also improves the application feel. It can give a velvety, non-tacky finish. It helps products spread easily on the skin.

Applications of Cosmetic Raw Material SiO2 Fumed Silica

Fumed silica is silicon dioxide. It is a common cosmetic ingredient. It is made from vaporized silicon compounds. This process creates tiny particles. These particles have a large surface area. This makes them very useful in cosmetics. They thicken products well. Creams and lotions use it. It helps make them smooth. It prevents them from feeling too sticky. It gives a nice texture. It also helps powders work better. Face powders and eyeshadows use it. It makes them apply evenly. It stops them from clumping together. This is called anti-caking. It absorbs oils too. This is good for oily skin. It keeps makeup looking fresh longer. It gives a matte finish. Many people like this look. It reduces shine on the skin. It helps suspend other ingredients. This means things stay mixed in the product. Colors and sparkles stay put. It doesn’t feel gritty on the skin. It feels very soft. It improves the overall feel of cosmetics. It makes products easier to spread. It is a key raw material. Cosmetic labs rely on it. It helps create high-quality textures. Consumers enjoy the results. It is safe for skin use. Manufacturers trust its performance. It is a versatile powder. It solves many formulation problems. It works in liquid and powder formulas. It is effective in small amounts. This makes it cost-efficient too. Formulators appreciate this. It helps achieve desired product effects.

5 FAQs of Cosmetic Raw Material SiO2 Fumed Silica

What is fumed silica? Fumed silica is a special form of silicon dioxide. Manufacturers make it by burning silicon tetrachloride in a flame. This process creates very fine particles. These particles are extremely small and have a large surface area. This makes fumed silica useful in many products.

Why use fumed silica in cosmetics? Fumed silica has several key jobs in cosmetics. It thickens liquids. It prevents powders from clumping together. It helps control how shiny or matte a product looks. It improves the texture. It makes products feel smooth on the skin. It helps other ingredients spread evenly. It absorbs oils. This is good for products that need to stay dry.

Is fumed silica safe for skin? Yes, fumed silica is safe for cosmetic use. Regulatory agencies approve it. It is non-toxic. It is chemically inert. This means it usually doesn’t react badly with skin. It is considered safe when used properly. Cosmetic formulas use specific grades designed for skin safety.

Where is fumed silica used in cosmetics? You find fumed silica in many common products. It is in foundations and powders. It helps them apply smoothly. It is in lipsticks. It prevents them from feeling greasy. It is in creams and lotions. It thickens them and stops separation. It is in sunscreens. It helps the formula stay stable. It is in makeup primers. It controls shine and oil.

Why pick fumed silica over other silicas? Fumed silica has unique properties. It is very good at thickening liquids without making them feel gritty. It absorbs liquids and oils effectively. It acts as an anti-caking agent very well. It provides a light, silky feel. This is different from some other silica types. Other silicas might feel heavier or work less effectively. Fumed silica offers strong performance at low usage levels.
