There’s nothing quite like watching a bath bomb fizz, swirl and fill your bath with beautiful colour and scent. But have you ever wondered what actually makes that magic happen?

Behind every fizz, bubble and burst of fragrance is a clever little bit of science — and a lot of love that goes into making the perfect handmade bath bomb.

At Replenish Heaven, we handcraft each bath bomb with natural, skin-loving ingredients designed to nourish your skin and calm your mind. Let’s take a look at what’s really happening when your bath bomb hits the water.

🧪 The Two Key Players: Bicarbonate of Soda & Citric Acid

These two ingredients are the stars of the show!

When your bath bomb drops into the water, bicarbonate of soda (sodium bicarbonate) and citric acid react together to release carbon dioxide bubbles — that’s the fizzing magic you see.

This reaction helps to:
✨ Spread the scent and colours evenly through your bath
✨ Soften the water for a silky skin feel
✨ Release the fragrance oils for a full aromatherapy experience

That simple combination is what turns bath time into pure bliss!

🌿 Skin-Loving Additions: Butters, Oils & Clays

The best natural bath bombs don’t just fizz — they pamper.
At Replenish Heaven, we use shea butter, cocoa butter, and coconut oil to deeply moisturise your skin as you soak. These ingredients melt into the bathwater, leaving your skin soft, nourished and lightly scented.

You’ll also find kaolin clay in some of our handmade bath bombs — a natural clay that gently purifies and adds a luxurious creamy texture to your soak. It’s perfect for sensitive or dry skin.

🌸 The Scent Science: Essential & Fragrance Oils

Scent is where the magic really happens.
Our bath bomb ingredients include carefully chosen blends of essential oils and fragrance oils to create everything from fruity freshness to cosy vanilla and amber notes.

• Essential oils add natural aromatherapy benefits — lavender to relax, peppermint to refresh, chamomile to calm.

• Fragrance oils help your scent last longer and fill the room beautifully.

As your bath bomb fizzes, these oils are released into the air and onto your skin, turning your soak into a spa-like ritual.

🌈 Colour, Mica & Decoration: The Finishing Touches

Those gorgeous swirls of colour come from skin-safe, water-soluble dyes and natural mica powders.

We also use biodegradable glitter to keep your bath sparkling and eco-friendly. Our colour choices are tested carefully so your bath looks dreamy — without staining your skin or tub.

Because self-care should be stress-free ✨
