You want a custom body wash that smells exactly the way you love — but every pre-scented bottle either fights your favorite essential oils (concentrated plant extracts that carry the plant’s natural scent) or leaves your skin irritated. The real trick is finding a blank, unscented base that plays nice with whatever oils you add, so you get that perfect fresh scent without any wrong notes or skin reactions.

Use this guide to find a concentrated body wash to mix with essential oils that treats your skin right and lets your custom scent shine.
Our Picks at a Glance
How To Choose The Best Concentrated Body Wash to Mix with Essential Oils
Choosing the right base means looking past the pretty packaging and focusing on what lets those essential oils do their job. You need a completely neutral canvas that doesn’t fight your custom scent and won’t irritate your skin when you start blending. Here are the main things to consider when picking a concentrated body wash for your DIY creations.
Start with a Truly Fragrance-Free or Unscented Base
The single most important rule for mixing with essential oils is starting with a base that has no added fragrance of any kind. “Fragrance-free” means no synthetic or natural scents have been added, while “unscented” can sometimes mean a scent-masking agent is present. For the truest blank slate, look for both fragrance-free and unscented labels. This ensures your essential oil blend is the only scent you smell in the shower.
Check the Concentration Level
Concentrated body washes (like castile soaps or thick gels) give you the control to dilute them exactly how you like and allow the essential oils to mix in more evenly. A thin, watery base will separate faster and may change the consistency of your final product. Thicker formulas also mean you use less product per wash, making that gallon jug last even longer. This is especially important if you plan to gift your custom blends or make them in bulk.
Look at the Base Ingredients for Skin Compatibility
The base formula determines how gentle the wash is on your skin. For sensitive or dry skin, look for soothing ingredients like ceramides, colloidal oatmeal, or organic oils (olive, coconut, jojoba). These protect your skin’s barrier while you experiment with essential oils. Avoid harsh sulfates (SLS/SLES) or synthetic foaming agents, as they can strip moisture and interact poorly with essential oils, especially on sensitive skin.

In‑Depth Reviews
1. The Honest Company Shampoo & Body Wash
Our pick — over 4.5★ from 46,500+ verified ratings; the strongest balance of quality and price.
The crowd-favorite 2-in-1 that babies, kids, and adults all seem to agree on.
This fragrance-free formula from Honest is a surprisingly versatile base for essential oil blending. It is a 2-in-1 shampoo and body wash that comes in at 2.47 pounds (the heaviest among the smaller bottles here, noticeably bigger than the 1.05-pound Naturium). What wins people over is how gentle it is — physician-tested, hypoallergenic (meaning it is less likely to cause an allergic reaction), and free of phthalates (chemicals that soften plastics), parabens (preservatives), dyes, and SLS/SLES (sulfate-based foaming agents that can dry out skin). That means your essential oils go into a completely neutral, non-irritating starting point.
The texture is what makes it a great DIY canvas. It foams up beautifully without being harsh — buyers report it gets “so foamy” in shampooing, which tells you the lather is rich and stable enough to carry your custom scent. A few owners mention the pump design can accumulate water, so if you plan to mix a large batch, consider decanting into a separate bottle.
What owners love
- Extremely gentle on sensitive skin and babies — 1,500+ call out the fragrance-free quality
- Leaves gray and normal hair soft without the yellow tinge
- Dermatologist tested and tear-free for stress-free bath time
The honest catch
- A few find it drying on hair despite the general moisturizing feel
- Pump design can breed bacteria if water sits in the nozzle
- Premium price for the size compared to bulk castile options
Consider another if: You prefer a super-concentrated castile soap for bulk mixing — this is a ready-to-use gel, not a dilution concentrate.
2. Naturium The Calmer Ceramide Body Wash
The dermatologist darling that soothes while it cleans — perfect for stressed-out skin.
This 16.9-oz fragrance-free wash is built around calming ceramides (lipid molecules that help your skin hold onto moisture) and colloidal oatmeal (finely ground oats that calm irritation), making it a prime base for anyone with dry, itchy, or sensitive skin. It’s also 6% larger than the 16-oz LandLSoap castile, so you get a touch more volume for your blending project. The texture is “plush and creamy” according to reviewers, and it foams nicely without any synthetic fragrance getting in the way of your essential oils.
What’s clever here is its versatility. Owners use it as a face wash, shaving cream, and even a shampoo for textured hair. One reviewer found it wasn’t their favorite as a daily body wash but discovered it worked “fantastic for shaving my legs” because of the slip and moisturizing effect. The star ingredient — ceramides — supports your skin barrier while you enjoy your custom scent, so you’re not trading fragrance for health.
The defining quality: The skin feel is what owners praise most — 32 call it out, with creamy, silky results that leave no film. If your skin gets angry with new blends, this base gives you a safety net.
Your go-to for sensitive skin: If you want a soothing, luxurious base that hydrates while your essential oils do the aromatherapy, reach for Naturium.
Pass if: You need a super-concentrated formula to dilute — this is a ready-to-use wash, not a castile concentrate.
3. Antibacterial Unscented Pure Castile Liquid Soap (LandLSoap)
The unscented castile that owners mention is “the best” for a reason — it just works.
This 16-oz castile soap from LandLSoap is a true blank slate: no added fragrance, no sulfates, and made from all-natural, ethically sourced ingredients. It’s a concentrated liquid, meaning a little goes a long way when you dilute it for body wash or face washing. The standout feature here is the antibacterial property — rare in the unscented world — which buyers call “the best unscented antibacterial soap on the market.” It foams like crazy and leaves skin feeling soft, not stripped.
The versatility is immense. Owners use it on their face for acne, as a hand soap, and even to clean CPAP equipment. Because it’s concentrated, you can mix it with a carrier oil and your essential oils to create a custom body wash that suds up well. The only note of caution is the consistency — it’s thick and may need a vigorous shake or stir when you first mix in your oils to avoid separation.
Why it stands out: Cleaning power is what owners praise most — 39 highlight how well it cleans without the need for synthetic sudsers. If you want a base that truly purifies, this is a strong contender.
Grab this if: You need an antibacterial blank slate for acne-prone skin or want a bulk, no-nonsense DIY base for the whole house — it’s great for body, face, and even cleaning.
Think twice if: You have very dry skin; the castile can feel slightly drying if you don’t dilute enough or add a moisturizing carrier oil.
4. Seaweed Bath Co. Hydrate Body Wash
A foaming gel that hydrates with seaweed and works double duty as a shaving cream.
This pack of two 12-oz bottles brings organic seaweed, spirulina, kukui oil, and aloe vera into your custom blend. The foaming formula is a gel rather than a watery soap, so it holds essential oils well without immediate separation. It’s also Leaping Bunny certified (meaning no animal testing) and made with 50% post-consumer recycled plastic — a nice eco touch for the environmentally conscious mixer.
Owners rave about how it leaves skin feeling smooth and moisturized, and some say it has a “calming” effect that makes it perfect for a bedtime wash. Since it’s completely fragrance-free, your essential oil blend will be the only star. The texture works as both a body wash and a shaving gel, giving you two uses from one base. The only catch is the smaller 12-oz size — if you’re mixing large batches, you’ll need to stock up on multiple packs.
The straight truth: The scent gets 29 positive mentions, which is impressive for a fragrance-free product — it means the natural seaweed and aloe smell pleasant on their own, so your oils will only make it better.
Ideal for: A luxurious, hydrating base that works as a shaving cream and body wash in one. Great for dry skin that still wants a rich foam.
Skip if: You need a super-cheap bulk option — the 12-oz size means per-ounce cost is higher than gallon castile jugs.
5. YARELI Pure Castile Soap Liquid Unscented
A half-gallon of EWG Verified castile soap with six organic oils — the DIY dream base.
The versatility is off the charts. Owners use it for body wash, face wash, makeup remover, laundry, dishes, and pet shampoo. It’s concentrated, so you dilute it yourself, which is perfect for mixing in your essential oils at your preferred strength. A few owners note the lather is less than mass-market soaps, but that’s typical of true castile — the trade-off is a much gentler, more natural clean.
What the data says: Quality is praised most by 57 owners, calling it a “quality lather” that doesn’t dry sensitive skin. If purity and natural ingredients matter most, this is your pick.
Great for: Heavy DIY users who want a single base for body, home, and pet care — the 64-oz bottle lasts months, even with frequent mixing.
Not for you if: You want a ready-to-use gel; this requires dilution and a bit of trial to get the right soap-to-oil ratio.
6. Illiyoon Ceramide Ato 6.0 Top to Toe Wash
A Korean beauty 3-in-1 that treats your skin as gently as a newborn’s — and the 4.6-star crowd agrees.
This 16.9-oz gel from Illiyoon is a head-to-toe wash designed for the whole family, including newborns. It’s completely unscented and uses a low-pH (slightly acidic, matching your skin’s natural level) formula with ceramides (natural fats that lock in moisture) to protect the skin barrier. The “Ato” in the name refers to atopic (eczema-prone) skin — the brand claims it cleanses away 99.9% of germs while being so mild it won’t strip the skin’s natural moisture.
what separates it is the moisturizing payoff. Owners with severely dry skin call it “absolutely perfect” and say it helps their skin absorb creams better. It works equally well as a shampoo, leaving hair shiny. The catch is that some users find it stings the eyes (ironic for a baby product). If you plan to use this as a shampoo for your custom blend, just keep it away from eyes.
The winning stat: Moisturizing is praised most — 44 owners highlight how it hydrates without leaving any greasy film. This is a brilliant base for dry-skin essential oil recipes.
Perfect for: Anyone with dry, eczema-prone, or baby-sensitive skin who wants a low-pH, ceramide-rich base for their custom scents.
Try another if: You want a concentrated castile for household cleaning or bulk mixing — this is a ready-to-use gel, not a concentrate.
7. NaturSense Organic Castile Soap Liquid Unscented
A true organic concentrate that dilutes more than the rest — perfect for foaming dispensers.
NaturSense delivers a 64-oz half-gallon of castile soap made entirely from certified organic plant oils, and it’s proudly palm-oil-free. This is a highly concentrated liquid, and owners specifically say it “dilutes more than others,” working beautifully in foaming hand soap dispensers (containers that mix soap with air to create a rich, foam lather). The texture is described as “not too thick or too thin” — just right for blending essential oils evenly.
Versatility is the big story here. It works as a body wash, hand soap, face wash, shampoo, dish soap, mopping solution, and pet wash. Buyers love using it for DIY projects, from toddler bath bubbles to homemade foaming soaps. Because it’s unscented and organic, it’s a blank canvas that respects both your skin and your essential oil investment. The only potential downside is that some owners have had issues with fat separation between bottles, so give it a good shake before each use.
What owners say: Versatility is praised most — 33 highlight that one bottle replaces dozens of single-use products. If you want to simplify your bathroom while making custom blends, this is a winner.
Get this for: Serious DIYers who want an organic, palm-oil-free concentrate that works everywhere — body, home, and pets — and dilutes far more than mass-market castiles.
Pass on it if: You need a pre-mixed, ready-to-use body wash; this is a concentrate that needs water and oil added.
8. Goat Milk Unscented Pure Castile Soap (LandLSoap)
A thick, hand-crafted castile from Oklahoma that some say beats the legendary Dr. Bronner’s.
This 64-oz half-gallon uses goat milk as a key ingredient, which brings natural moisturizing and soothing properties that plain castile soaps lack. Owners with eczema and sensitive skin find it especially gentle — “clears hands, leaves clean feel” is a common refrain. The consistency is noticeably thick (no thickeners added), which means it dilutes really well and can be used straight for tough cleaning jobs.
A few owners find it “hard to foam” compared to synthetic soaps, and one specifically noted that “it doesn’t mix well with added oils.” That’s a crucial heads-up for the essential oil mixer: the thick, milk-based formula can be finicky with oil incorporation. Stirring or shaking vigorously should solve it, but be prepared for a bit of effort. Otherwise, the clean is described as crisp and residue-free.
The bottom line: Cleansing and quality both get 29 positive mentions. If you want a thick, hand-crafted castile for eczema-prone skin, this is a top choice — just expect to work a little harder to blend your oils.
Best suited for: Those with eczema or ultra-sensitive skin who want a thick, natural base. The goat milk adds extra moisture that plain castile lacks.
Consider alternatives if: You want a simple to use oil mixer — the thick consistency and goat milk can make blending slightly harder than with thinner castiles.
9. VERMONT SOAP Body Wash with Shea Butter
A 64-oz jug from master soapmakers who have been crafting since 1992 — experience in every drop.
Vermont Soap’s unscented body wash is a serious player for anyone who wants both volume and purity. It’s USDA organic certified, vegan, and free of sulfates, petrochemicals, and artificial colors. The base is built around organic aloe vera, coconut oil, shea butter, olive oil, jojoba, and rosemary oil — a rich blend that leaves skin feeling moisturized without a greasy film. It has a natural, minimal scent that owners appreciate, making it a very forgiving canvas for your essential oils.
Owners with sensitive skin and eczema find it soothing, and the fact that it lathers well despite being all-natural is a big plus. One owner described their skin as “always moisturized and smells beautiful” when using it. Because it’s 64 oz, you have plenty to experiment with different dilutions and oil blends. A few users note it’s a “little expensive for size” but consider it worth it for the organic purity.
What stands out: Fragrance gets 47 positive mentions — which for an unscented product means the natural ingredients smell fresh and pleasant on their own. Your essential oils will have a lovely, clean background to sit on.
Reach for this if: USDA organic certification matters to you and you want a large-format, moisturizing base that lathers without synthetic help. Great for the whole family.
Think twice if: Budget is your primary concern — the per-ounce cost is higher than basic castile concentrates, even though the ingredient quality is exceptional.
Understanding the Specs
Castile Soap vs. Gel Body Wash
Castile soap (like YARELI or NaturSense) is a concentrated liquid made from plant oils — you dilute it yourself with water and can add essential oils at any ratio. It’s the most flexible choice for DIY blending. Gel body washes (like Honest Co. or Naturium) are ready-to-use and already have the right viscosity (thickness), so your oils mix in easily but you have less control over final thickness.
Ceramides and Skin Barrier
Ceramides are lipid (fat) molecules that naturally occur in your skin’s outer layer. When you use a body wash with ceramides (like Naturium or Illiyoon), you’re helping your skin hold onto moisture and stay protected while the essential oils do their job. This is crucial if you have dry, itchy, or sensitive skin — it prevents the wash from stripping your natural barrier.
