Silica Gel is a versatile, food-grade, odourless, non-toxic, non-flammable desiccant that absorbs up to 30% of its weight. Silica gel is also a non-corrosive desiccant and can be reactivated and reused if required. Silica gel is used to prevent spoilage and shelf life in the pharmaceutical and food industry. Silica gel prevents mould in leather goods, photo albums etc. They also prevent corrosion in any steel products and camera and electronic equipment. Silica gel is great for manufacturing companies producing powder products to prevent clumping due to moisture.

Safeguard your products from humidity, mould, and degradation with our premium Silica Gel desiccants. Made from porous, granular silicon dioxide (SiO₂), silica gel adsorbs up to 30% of its weight in moisture by binding water molecules to its vast surface area without changing shape or texture. This makes it an ideal solution for protecting electronics, pharmaceuticals, clothing, leather goods, food packaging, tools, and collectibles.
Our food-grade, FDA and EU-compliant Silica Gel sachets are available in a wide range of sizes (0.5g to 500g) and are packaged in high-quality, tear-resistant Tyvek or Aihua Paper bags. These sachets are non-toxic, odourless, non-flammable, and chemically stable, making them safe for indirect contact with food (but not for consumption).
We offer both non-indicating and indicating types of silica gel:
- White (Non-Indicating): Standard, food-safe silica gel with no colour change.
- Orange (Indicating): Food-safe variant that turns green when saturated, using a non-toxic indicator.
- Blue (Indicating): Industrial-grade only. Turns pink when saturated. Contains cobalt chloride and is not food safe.
Why Choose Our Silica Gel Desiccants?
- Superior Moisture Control: Prevents mould, corrosion, spoilage, and clumping
- Reusable & Cost-Effective: Can be reactivated through heating
- Versatile Applications: Ideal for food packaging, pharmaceuticals, electronics, and more
- Eco-Friendly Choice: Long-lasting and non-toxic
- Visual Indicators Available: Easily monitor saturation with orange or blue gels

No. Silica gel is non-toxic but not edible and may cause choking or discomfort.
Silica gel is commonly used in electronics, food, vitamins, clothing, leather goods, toolboxes, safes, and shipping containers.
In sealed packs – years. Once exposed, its lifespan depends on humidity and air exposure.
General guide: 5 g per 1L of air volume. For bulk use (e.g. containers), use desiccants in grams to kilograms.
See type comparison table below.
The main difference between Silica Gel and Oxygen absorber is their function: • Oxygen Absorbers remove oxygen from sealed packaging to prevent spoilage, oxidation, and mold growth in food and sensitive products. • Silica gel absorbs moisture (humidity) to prevent condensation, mold, and corrosion inside packaging and storage containers. Both are essential for long-term preservation, but they serve different purposes.
Yes. Silica gel beads, especially those with indicating colours (e.g. pink to blue), can usually be reactivated and reused 3 to 5 times before their performance starts to decline.
Silica gel can be reactivated by removing the absorbed moisture using heat.
Microwave
: Place silica gel beads in a microwave-safe container. Use the defrost setting for 7–12 minutes, checking frequently to avoid overheating. Do not use high heat.
Oven
: Spread the beads in a shallow tray and bake at 200–250°F (up to 120°C) for 30 minutes to 2 hours. Do not exceed 125°C.
Colour Check:
Gel is fully reactivated when it returns to its original colour (e.g. deep blue for indicating gels).
Note
: Reactivation can be repeated several times, but performance may decline due to contamination or overheating.
Yes, silica gel is generally non-toxic and safe to handle. It’s a synthetic form of sand designed to absorb moisture. Some indicating gels may contain additives that could cause mild skin irritation, but it is safe for most people.
Humans: Silica gel is chemically inert and non-toxic, but medical advice should be sought, especially for indicator gels or large quantities.
Pets: Contact a veterinarian. Risks include intestinal blockage or exposure to absorbed toxins, particularly if the sachet was used in food or medication packaging.
No. Silica gel sachets are ready to use straight out of the packaging.
Store silica gel in a sealed, airtight container. Avoid exposing it to open air for more than 15 minutes, as it will begin to absorb moisture and lose effectiveness.
Silica gel can be disposed of in household rubbish. If it has absorbed hazardous substances, follow the same disposal guidelines as the contaminant.

Silica Gel is a porous, granular desiccant made from amorphous silicon dioxide. It adsorbs moisture to protect products from humidity.
Silica Gel adsorbs (not absorbs) moisture onto its surface, keeping environments dry and stable.
Yes – food-grade white or orange silica gel is non-toxic. Blue silica gel is not food safe.
Yes. Reactivate silica gel by heating at 120°C (250°F) for 1–2 hours to release moisture.
