Why Choose Fizzy Bath Powder Recipe Over Bath Bombs

While bath bombs are popular for their effervescent delight, fizzy bath powders offer a more versatile and customizable option. 

Unlike bath bombs, bath powders allow you to control the amount used in each bath, ensuring the perfect level of fizz and fragrance every time. 

They are easier to make, store, and can be tailored with various ingredients to suit your specific needs.

Calendula Bath Benefits

Calendula, a vibrant and sunny flower, has been cherished for centuries for its healing properties. Known for its anti-inflammatory and antimicrobial benefits, calendula is a star ingredient in skincare, promoting healthy, glowing skin. 

When infused in bath products, calendula can soothe irritated skin, reduce redness, and provide a calming effect, making it a perfect addition to your bath-time routine.

Anti-Inflammatory Properties: Calendula is renowned for its powerful anti-inflammatory properties. The flower contains compounds like flavonoids and saponins that help reduce inflammation, making it an excellent remedy for soothing irritated skin conditions such as eczema, dermatitis, and psoriasis. 

Wound Healing:  One of the most celebrated benefits of calendula is its ability to promote wound healing. Calendula stimulates collagen production, which is crucial for wound repair. It also enhances tissue regeneration and helps prevent infection, making it effective in treating cuts, scrapes, and minor burns.

Moisturizing and Hydrating:  Calendula has natural moisturizing properties that help keep the skin hydrated. It is particularly beneficial for dry or sensitive skin types. The emollient properties of calendula help to lock in moisture and prevent water loss, which is essential for maintaining healthy skin barrier function.

Antimicrobial and Antifungal:  Calendula has antimicrobial and antifungal properties that make it effective in treating a variety of skin infections. The antimicrobial action of calendula helps to cleanse wounds and prevent infection, promoting faster healing.

Antioxidant Protection:  Calendula is rich in antioxidants, such as carotenoids and flavonoids, which help protect the skin from oxidative stress and environmental damage. These antioxidants neutralize free radicals, preventing premature aging and maintaining youthful, healthy skin. 

Soothing and Calming: Calendula is highly effective in soothing and calming the skin. It is often used in products designed for sensitive skin due to its gentle nature. 

Homemade Herbal Bath Powder Ingredients

Baking Soda and Citric Acid:  The foundation of any fizzy bath powder recipe is a combination of baking soda and citric acid. These two ingredients react with water to create the delightful fizz. Baking soda can also help soothe irritated skin in a batb.

Dried Calendula PetalsDried calendula petals not only add a touch of beauty to your bath powder but also infuse the water with their healing properties. When selecting calendula petals, opt for high-quality, vibrant petals to ensure maximum benefits.

Carrier Oil and Essential Oils: Using a carrier oil and essential oils is optional.  I recommend using a carrier oil for dry skin like avocado oil or sunflower oil.  Learn more about carrier oils and their benefits.  You can use your choice of essential oils.  Lavender essential oil or frankincense essential oil would both be great options.

I used 6 drops of essential oils for a 1 percent dilution.  Always dilute essential oils with a carrier oil and use an essential oil dilution chart to know how much to add.

Optional Add Ins

Since this is a dry herbal bath powder recipe, you can easily add other dry ingredients.  I recommend adding up to 1/4 cup per batch.

  • Cornstarch adds a silky texture to the bath water, leaving your skin feeling soft and smooth. Sea salt, with its rich mineral content, helps detoxify and rejuvenate the skin, enhancing the overall bathing experience.
  • Colloidal oatmeal can be included for its moisturizing and anti-inflammatory properties. It is particularly beneficial for sensitive or irritated skin, adding an extra layer of nourishment to your bath.
  • Epsom salt adds magnesium to your soothing bath soak.  This can help with sore muscles.
  • Sea salt can improve circulation and help you relax.
  • In addition to calendula, other botanicals like lavender buds, chamomile flowers, and rose petals can enhance the visual appeal and therapeutic benefits of your bath powder.

For a standard-sized bathtub, use about 1/4 to 1/2 cup of bath powder. Adjust the amount based on personal preference and the desired intensity of the fizz and scent.

You can also place the diy soothing bath soak in a muslin bag and place in the water.  This helps to contain the calendula petals so they don't risk clogging your pipes.
