Silicon Dioxide
What is silicon dioxide?
Silicon dioxide is an organic compounds that has the SiO₂ formulation which is a purified crystal form of quartz, refined to produce high-purity silica—ideal for use in food, pharmaceutical, cosmetic, and chemical industries.
Even though the name of “SiliconDioxide" is similar to “Silica Gel" but both of them are different substances in both structure and usage.

Product Details
The differences between Silicon Dioxide and Silica Gel
| Comparing lists | Silicon Dioxide | Silica Gel |
|---|---|---|
| Chemical appearances | An inorganic compound made of silicon (Si) and oxygen (O), available in crystalline or fine powder form | Amorphous Porous Silica |
| External appearances | Fine white powder, odorless, and insoluble in water | Appears as small, clear or translucent round beads, similar to tiny pearls |
| Methodology | Derived from purified quartz and synthesized under controlled conditions | Made by reacting sodium silicate solution with sulfuric acid |
| Key Applications | Used in food as an anticaking agent, flavor carrier, thickener, and defoaming agent | Commonly used as a desiccant in packaging, storage cabinets, electronics, and more |
| Key featured | Food-grade, chemically stable, and safe for consumption | Highly effective at absorbing moisture and water vapor |
| Food status | Approved as a food additive under the code E551 | Not suitable for consumption and not approved for use in food |
The usage of Silicon Dioxide in the industries
Food and bakery industries
- Used as an Anticaking Agent
- Used as coloring/flavor carrier
- Used as an Antifoaming Agent in the manufacturing of seasoning powders, powdered drinks and sauces
Rubber and cosmetic industries
- Used as a flow aid and bulking agent in tablet production
- In cosmetics, it helps absorb excess oil and improves product texture for a smoother finish
Chemical and material industries
- Serves as a raw material in the production of silicone, glass, ceramics, and silicone rubber
Silicon Dioxide is a safe and widely used ingredient in food and chemical industries. In contrast, Silica Gel is a moisture absorber intended for external use and not suitable for direct consumption. While both originate from silica, they differ in structure, function, and application.
The frequently asked question (FAQ)— Silicon Dioxide
1. What is Silicon Dioxide?
It's a compound substance of silicon and oxygen (SiO₂) used as a food addictive (E551), such as anticaking agents, dispersing agents, colorants, fragrances and defoaming agents
2. Is it different from silica gel?
Yes, it's different.
Silicon Dioxide is a food grade
but silica gel a desiccant. Do not consume.
3. Using for what type of food?
Found in a seasoning powder, soup powder, powder, bakery, and dry ground spices to prevent the powder from clumping
4. Is it safe?
Safe for use in food—approved by both the FDA and EFSA.
Recommended usage: no more than 2% of the product or 25 mg per kg of body weight per day
5. Is it melting in the water?
It's not, but it's well dispersed in the liquid, not reacting to other substances
6. Can it be used in the cosmetic industry?
It is, used in loose powders and creams to absorb excess oil and enhance smooth texture
7. How to store it?
Keep in a dry place, tightly sealed, keep away from heat and moisture
Available in 20-25 kg / bag
