Bringing nature Indoors: A Guide to Using Flower Botanicals in bar Soap
There is something undeniably magical about turning a fragrant garden bouquet into a functional piece of art. Handmade soap, particularly when crafted using the melt and poor method, offers the perfect, gentle canvas for botanical ingredients. Using flower botanicals doesn't just make your soap look stunning—it adds natural color, texture, and a touch of luxury to your daily routine.
Whether you are a seasoned soapmaker or a beginner looking for a creative project, incorporating flowers is an easy way to elevate your soap from mundane to botanical beauty.
Why Use Botanicals in Soap?
Botanicals are natural ingredients derived from plants—roots, leaves, and, of course, flowers. In handcrafted soap, they serve several purposes:
Visual Appeal: Dried petals add a rustic, artisanal, and "boho" look to soap bars.
Gentle Exfoliation: Dried flowers like calendula or lavender buds can provide mild exfoliation for the skin.
Therapeutic Benefits: While they may not add much scent, botanicals like chamomile or calendula are known for their calming, soothing properties for sensitive skin.
Natural Color: Some flowers, like yellow calendula, can provide a sunny, lasting color to your soaps.
Best Flowers for Soap Making
Not all flowers hold up well in the high-pH environment of soap. Some turn brown or gray over time like rose petals, while others hold their color and shape perfectly. Here are the best flowers to start with:
Calendula Flowers (Marigolds)
Calendula is the superstar of botanical soapmaking. Its bright yellow and orange petals hold their color exceptionally well, even when mixed into the soap batter. They are renowned for their soothing and healing properties.
Lavender Buds
Lavender is beloved for its classic, relaxing scent and calming,, and and and "purple" appearance. While the buds may turn a light brown inside the soap, they look beautiful on top, especially when paired with lavender essential oil.
Chamomile Flowers
These small, sunny flower heads are perfect for a gentle, calming soap. They add a soft,, rustic look and offer skin-soothing properties, making them ideal for sensitive skin.
Rose Petals
Dried rose petals are wonderful, particularly as a topping, adding a luxurious feel to your bars. Keep in mind that they may turn a darker, rust-brown color over time.
Blue Cornflowers
These are perfect for adding a pop of color to the top of your soap, as they retain their vibrant color better than most other petals.
Ways to Incorporate Botanicals
As a Topper
Sprinkling dried flowers on top of your soap is the easiest and most popular method. This works best when the soap batter is thick enough to hold the weight of the flowers, usually at a "medium trace" (when the soap mixture has a custard-like consistency).
Pro Tip: To prevent the flowers from browning or rotting, ensure your soap cures in a dry, low-humidity environment.Infused Oils
Instead of putting raw flowers into the soap, you can infuse them into your oils beforehand.
Cold Method: Fill a jar halfway with dried flowers and cover with olive oil. Let it sit in a dark place for 3–6 weeks, shaking daily, then strain.
Hot Method: Gently heat the flowers and oil in a slow cooker on low for 1-5 hours, then strain.
As Exfoliant (Inside the Soap)
For a scrubby soap, you can add finely ground dried herbs or flowers directly to the soap batter at light trace.
Essential Tips for Success
Always Use Dried: Never use fresh flowers in soap, as they contain water that can cause mold and rot within the bar.
Embrace the Browning: Accept that most flowers will turn brown or beige over time. This is a natural reaction to the lye.
Use Proper Safety Equipment: When making soap from scratch (cold process), always wear gloves and eye protection.
Disclaimer: Some botanicals may cause skin sensitivity. Always test a small area of skin before using, and ensure you are not allergic to any flowers used.
Enjoy the process of creating beautiful, natural, botanical soaps!
