What is Citric Acid Powder? Uses, Benefits & Safety Tips
In the modern world, citric acid powder is widely used across various industries due to its versatility. From food and beverage manufacturing to personal care products, household cleaning, and even industrial processes, citric acid offers a wide range of benefits.
What Is Citric Acid Powder?
Citric acid powder is a natural substance found in citrus fruits like lemons, limes, and oranges. It has a sour taste and comes in the form of a white, odourless powder made from clear crystals. Even though it’s found in fruit, the powder is often made through a natural fermentation process in factories.
It’s very useful in many areas—food, cleaning, skincare, and DIY projects like bath bombs.
How Citric Acid Powder Is Used in Bath Bombs
One of the most popular uses for citric acid powder is in making bath bombs. When you mix it with baking soda (also known as sodium bicarbonate), you get that fun fizzing reaction when the bath bomb touches water.
You can mix in colours, fragrances or essential oil to create fun and relaxing bath time treats.
- Add essential oils for a calming effect.
- Use body & colours to make them bright and fun.
- Try layering colours or adding a surprise inside!
Making bath bombs at home is fun and easy, and citric acid powder is a must-have for this DIY project.
