QUICK SUMMARY
This homemade liquid hand soap with essential oils uses liquid Castile soap, Mama Z’s carrier oil base, vitamin E, and essential oils for a simple, naturally scented alternative to conventional hand soap. Make the soap concentrate first, then dilute a small amount with distilled water when you’re ready to use it. Castile soap does the cleaning, while the oils add fragrance and skin-conditioning benefits.
One of the first things to do when you start living naturally is rid your home of toxic cleaners and body-care products. There’s no need to have unnecessary synthetic fragrance and other questionable ingredients around when simple natural ingredients get the job done!
This homemade liquid hand soap is easy to make and uses ingredients I love keeping in my non-toxic medicine and body-care cabinet. It cleans your hands without relying on antibacterial drug ingredients, gives you complete control over the fragrance, and includes nourishing oils that help counter the dry feeling frequent handwashing can cause.
I keep this DIY in my cupboard at all times! Caring for the bodies God gave us can start with something as simple as the soap by the sink.

- Fill your hand soap containers with half soap mixture and half distilled water to make it easier to pump out. This also stretches your mixture!
Step One: Add Castile Soap
Slowly pour the castile soap into the jar.
Step Two: Add Essential Oils
Add the vitamin E, Mama Z’s oil base or carrier oil, and essential oils. Top with a sealed lid and shake well to blend.
Step Three: Dilute and Use
When you’re ready to use, fill a glass jar with a half soap solution and half distilled water. This makes it easier to pump out. It also stretches your liquid hand soap!
For effective handwashing, wet your hands with clean running water, apply soap, lather all surfaces, scrub for at least 20 seconds, rinse well, and dry.
How to Store Homemade Liquid Hand Soap
You can store the leftover homemade liquid hand soap (without water) until your containers need a refill; just remember to always shake well before using.
Important storage note: Once water is added, the soap can grow bacteria, yeast, or mold, because it has no preservative.
So mix only the amount of diluted soap your family will use quickly. Keep the bottle and pump clean, avoid topping off old diluted soap with a new batch, and discard the mixture if the smell, color, texture, or appearance changes.
Homemade Liquid Hand Soap Ingredients
Each ingredient was chosen with care, so your skin is nourished as well as cleansed. Here’s what you need.
Liquid Castile Soap: This vegetable oil-based soap is the foundation of the recipe. Soap helps lift dirt, grease, and microorganisms from the skin so they can be rinsed away with running water. You don’t need antibacterial drug ingredients for routine handwashing.
Mama Z’s Oil Base or Carrier Oil: I recommend using my carrier oil base whenever you can! It’s a lovely combination of carrier oils that provide moisturizing benefits. If you don’t have a batch on hand, you can use your favorite carrier oil. I like using sweet almond oil in this recipe!
Carrier oils dilute essential oils and provide skin-conditioning benefits. Because oils don’t naturally mix evenly with water, shake the finished mixture as directed.
Vitamin E Oil: I add vitamin E to many of my DIYs because it has antioxidant properties and is wonderful in skin-care formulations.
Vitamin E can help slow the oxidation of oils, but it is not a broad-spectrum antimicrobial preservative. It cannot be relied upon to prevent bacterial, yeast, or mold growth in water-containing soap. (1)
Essential Oils: Essential oils are the cherry on top of an already fantastic recipe! You can use any of the suggestions below or develop your own blend. I like making different blends and gifting this DIY to loved ones. It’s an inexpensive gift that anyone can use!
Supplies: To make this recipe, you’ll need a glass jar to mix ingredients and a glass liquid soap bottle.
Must-Try Essential Oil Blends for Homemade Soap
Kicking synthetic fragrance to the curb is painless when you have endless essential oil blends! We often change our blends to fit our season in life or even the time of year. The sky is the limit.
These are some of our favorite combinations. Their names describe the aromas and blends we enjoy, not proven medical effects from a rinse-off soap.
- Christmas Blend: Fir needle (Balsam fir, Douglas fir, white fir), peppermint, and vanilla absolute
- Deep Breathing Blend: Cardamom, eucalyptus, lemon, peppermint, rosemary, tea tree
- Focus Blend: Cedarwood, frankincense, sandalwood, and vetiver
- Goodbye Allergy Blend: Lavender, lemon, and peppermint
- Healthy Digestion Blend: Anise, caraway, fennel, ginger, lemon, tarragon
- Immune Boosting Blend: Cinnamon leaf (bark would be too strong in this recipe), clove, eucalyptus, rosemary, orange, and lemon
- Happy Blend: Orange, lemon, bergamot, grapefruit, and vanilla absolute
- Sleepy Time Blend: Roman chamomile, lavender, and vetiver
Safety tip: Not every essential oil is appropriate for every person. Cinnamon, clove, peppermint, eucalyptus, and other potent oils can irritate sensitive skin, especially in children. Choose skin-appropriate blends, follow the recipe’s total essential-oil quantity, and stop using the soap if irritation occurs.
3 Ingredients We Avoid in Store-Bought Liquid Hand Soap
You might wonder why you should make your own body-care products. Several great brands contain no unnecessary synthetic fragrance, but they can be expensive. When you DIY simple products, you know exactly what’s going onto your skin and can save money on products your family uses every day.
Here are three ingredient categories we prefer to avoid when we can.
1. Synthetic Fragrance
Synthetic fragrance is common in liquid hand soaps and personal-care products.
Fragrance formulas may contain multiple ingredients, and some fragrance compounds can trigger sensitivities or allergic reactions. That is reason enough for us to choose fragrance-free products or make our own with carefully selected essential oils.
For our family, essential oils give us the scent we want without a mystery fragrance blend.
2. Formaldehyde-Releasing Preservatives
Some personal-care products contain preservatives that can release small amounts of formaldehyde. Formaldehyde is classified as a known human carcinogen, based mainly on people who breathed it in at higher levels. (2)
The more directly relevant concern in personal care is contact allergy. A systematic review found that formaldehyde and several formaldehyde-releasing preservatives remain meaningful allergens for some people with dermatitis. (3)
Choosing simpler products is one easy way we reduce that exposure in our home.
3. Certain Glycol Ethers
Glycol ethers are a broad family of solvents used in cleaners, cosmetics, paints, and other products. Some of them have raised health concerns at higher exposures. (4)
For our family, making simple products from recognizable ingredients means we can reduce unnecessary solvent exposure without becoming chemists in the grocery aisle.
Homemade Liquid Hand Soap FAQs
Does homemade Castile hand soap remove germs?
Yes. Plain soap, friction, and running water help lift and rinse away microorganisms, dirt, and grease. Scrub your hands thoroughly for at least 20 seconds.
Do essential oils make homemade hand soap antibacterial?
Many essential oils fight germs in lab studies, but this soap has not been tested as an antibacterial product. The Castile soap and a good 20-second scrub do the cleaning.
Is vitamin E a natural preservative?
Vitamin E is an antioxidant, not a complete antimicrobial preservation system for water-containing products.
How long does homemade liquid hand soap last?
The undiluted concentrate keeps until you need a refill; just shake it well before using. Once you dilute it with water, it has no preservative, so make small batches, keep dispensers clean, and use them up quickly.
Can I use tap water instead of distilled water?
Distilled water is best because it cuts down on contamination. Even so, diluted soap still needs to be used up quickly.
Can I use any essential oil blend in hand soap?
Choose oils appropriate for topical use and the people using the soap. Avoid increasing the essential-oil concentration for a stronger scent, and take extra care with children and sensitive skin.
