What Is Silica Gel & Why Are There Packets Of It In New Shoeboxes, Bags & Snacks?
No, it's not poison. But you still shouldn't eat it.
Cover image via You've definitely seen this mysterious white packet before. But what exactly is it?
Every time you unbox new shoes, open a handbag, or tear into a bag of snacks, there's always that tiny white sachet sitting there quietly with a dramatic warning: "DO NOT EAT".
Most of us either chuck it in the bin or assume it's some toxic preservative.
But guess what? That unassuming little packet actually plays an important role in keeping your stuff fresh and fungus-free.

That small white packet contains silica gel — a bunch of tiny, super thirsty beads made from a natural mineral called silicon dioxide
Silica gel is not food. It's a moisture magnet.
Its main job is to absorb moisture from the air so your new kicks, vitamins, or snacks don't turn into a mouldy science project.
It keeps things dry and odourless, especially in sealed packaging.

But why is it always hiding in shoeboxes, handbags, vitamin bottles, and snack packs?
The simple answer is that these are all moisture-sensitive products that would suffer in Malaysia's humid weather.
Items like leather shoes, handbags, electronics, and supplements can easily absorb moisture, which can lead to musty smells, bacterial growth, or even damage.
That's where silica gel saves the day. It traps water vapour and protects your precious items.

What happens if you accidentally eat it? Is it dangerous?
Silica gel isn't poisonous, but it's also not digestible, which is why it comes with that "DO NOT EAT" warning.
The danger lies in choking, especially for kids or pets. Some types of silica gel are dyed with cobalt chloride (blue packets), which can be harmful if ingested.
So, always keep them out of reach of curious mouths.

Fun fact: You can reuse it like a pro
Yep, silica gel is actually reusable. If it's still dry, you can reuse the packets to:
- Store with camera gear or lenses to prevent fog
- Keep spices or dried food crisp in jars
- Throw into gym bags, shoe cabinets, or wardrobes to fight smells and mildew
It's a low-key life hack not many people know about!
So, next time you see that tiny "DO NOT EAT" packet, don't toss it away
It's actually working hard behind the scenes to keep your stuff fresh and dry. Just don't eat it, lah.
