The Best Castile and Natural Soaps of 2026
2026-11-09 · Updated 2026-11-09 · 8 min · GoodCart Editorial
Soap is the product you use most and think about least. You wash your hands a dozen times a day. Shouldn't that soap be one of the best?
We went through every hand soap, bar soap, and body wash on GoodCart: 38 products, all of which have already passed our ingredient standards, with more than 300,000 Amazon reviews between them. Then we ranked them by what shoppers actually think. The result is a short list of soaps that are the best in their category, led by the castile classic from the brand that tops our multi-product personal care ranking.
How we ranked
- Ingredients first. Every soap here passed our ingredient standards before it was listed. We judge products by what's in them and what's not.
- Ratings plus review volume. Each product gets a Bayesian-weighted score that blends its average Amazon rating with its number of reviews. A 4.8-star soap with 70,000 reviews beats a 5-star soap with 10.
- Three categories. We looked at our Hand Soap, Bar Soaps, and Body Washes rankings, then ordered brands by their best-ranked soap. Brands whose soaps have only a few dozen reviews were left off the numbered list.
- Stats are brand-wide. Each stats line covers all of a brand's qualifying products on GoodCart, not just its soaps.
- Always current. Rankings update live from our catalog. Stats here are a snapshot from November 9, 2026.
What is castile soap?
Castile soap is a traditional style of soap made from plant oils rather than animal fats. Today the name shows up on liquid and bar soaps alike. On GoodCart, the castile soaps that rate highest with shoppers come from one brand, and it's first on our list.
1. Dr. Bronner's
★ 4.72 · 110,688 reviews · 8 products
The undisputed champion of natural soap. Dr. Bronner's holds the #1 spot in our Hand Soap category and our Body Washes category, plus #2 in Bar Soaps. Its 18-in-1 Hemp Peppermint Pure-Castile Soap has 72,569 reviews at 4.8 stars, the most of any liquid soap in our catalog. If you're buying one castile soap, buy this one.
Top soaps:
- 18-in-1 Hemp Peppermint Pure-Castile Soap: 4.8★, 72,569 reviews (#1 Hand Soap)

2. Mrs. Meyer's
★ 4.80 · 59,847 reviews · 1 product
Neck and neck with Dr. Bronner's. Mrs. Meyer's Iowa Pine Liquid Hand Soap carries the same 4.8-star rating with nearly 60,000 reviews, and it ties the top spot on our Hand Soap leaderboard on score. One product, an enormous fan base, and a scent people clearly come back for.
Top soap:

3. Dudu-Osun
★ 4.80 · 1,893 reviews · 1 product

4. Koala Eco
★ 4.60 · 263 reviews · 1 product
A smaller name with a big rating. Koala Eco's Natural Hand Wash ranks #5 in our Hand Soap category at 4.6 stars. Its review base is still modest at 263, so think of it as a rising star rather than a proven giant. It's still a strong pick for the bathroom sink.
Top soap:
- Natural Hand Wash: 4.6★, 263 reviews (#5 Hand Soap)
5. A La Maison de Provence
★ 4.60 · 345 reviews · 1 product
A liquid soap with a sense of place. A La Maison de Provence's Fresh Sea Salt Liquid Soap is rated 4.6 stars and ranks #6 in our Hand Soap category. Like Koala Eco, it's working with a few hundred reviews, so it ranks on rating more than volume.
Top soap:
- Fresh Sea Salt Liquid Soap: 4.6★, 345 reviews (#6 Hand Soap)
