Here’s Why Your Bath Bombs are Sticking to Your Moulds, and Here’s How To Prevent It

The art of creating bath bombs is a blend of colour, creation and customisable fun! Whether you are crafting them for yourself, gifting them to family and friends or making them for resale, it is an activity that ensures creative expression. However, this may all change when it is time to take them out – as sometimes they get stuck in the mould. Has this happened to you? Don’t worry! You’re not alone. Here is what to do if you get yourself in that sticky situation.

How To Stop Bath Bombs From Sticking To the Mould

Bath bombs are made with baking soda, citric acid, surfactant, and often some oils and colours. When mixed, these ingredients create a chemical reaction that fizzes in water, giving you a delightful bath experience. However, the same reaction can cause issues if the mixture isn’t just right.

When your mixture is too wet, it can create a sticky texture that clings to the sides of your moulds. You want your mixture to hold together like damp sand, not like mud. If it’s too loose or too wet, you’ll end up with bombs that are more like blobs—stuck in their homes, refusing to come out and play.

Use the Right Moulds

It is important to know that moulds can come in all shapes and sizes. The type of material that a mould is made from can be the difference in preventing your mixture from sticking. Some non-stick materials to use include:

• Silicone
• Stainless steel
• Acrylic
• Aluminium
• LDPE plastic

LDPE plastic moulds are made of high-quality materials, ensuring optimal durability. This particular material is easy to use and works effectively at releasing your bath bomb creation!

Perfect Your Timing

Once your mixture is in hand, it is best practice to let your bath bomb rest for a few of minutes before handling it further. Letting it sit for around 10 to 15 minutes is ideal, and this is crucial for allowing the ingredients to combine well with each other. Leaving this step out could result in bombs that want to stick around like a bad sitcom rerun.

Nail the Right Consistency

Getting your mixture just right is crucial. Too much liquid and you’ve got a sticky mess; too little and they won’t hold together. Aim for a consistency that you could form into a ball in your hand, but it shouldn’t crumble apart either. If you find your mixture is too wet, add a bit more baking soda to help dry it out. If it’s too dry, a few drops of water or oil can save the day, just be careful not to overdo it.

Store in a Cool Place

When you have finished crafting your bath bomb creations, it is important to keep them stored in a cool and dry place to let them set properly. If you leave them in a place that is exposed to high humidity levels, they can absorb the moisture, which will make them prone to stickiness. Think of it as if you’re making pizza dough. When rolling out the dough, you need to add flour to stop the dough consistency from getting too wet and sticky. The same applies to your bath bomb mixture. It needs to be stored in a dry place (such as an airtight container) and avoid as much moisture as possible.

Use a Release Agent

If you’ve tried it all and still face stubborn bath bombs, consider using a release agent. You can use a light dusting of sodium bicarbonate before moulding to ease the release.
