Ingredient Breakdown + Substitutions
Understanding why each ingredient is used will help you customize this formula and help you if you are missing an ingredient.
Distilled Water
What it does:
- Main solvent (base of the formula)
- Dissolves and carries all other ingredients
Why it’s used:
Water makes up the bulk of the hand wash and allows the surfactants to function properly.
Substitutions:
- Aloe vera liquid (replace up to 20–30%)
- Herbal infusions (short shelf life unless preserved properly)
Glycerin
What it does:
- Humectant (draws moisture to the skin)
- Helps disperse guar gum
Why it’s used:
Prevents the formula from feeling overly drying after washing.
Substitutions:
- Propanediol
- Sorbitol
- Honey (can make formula sticky and harder to preserve)
Guar Gum
What it does:
- Thickens the formula
- Creates gel-like texture
Why it’s used:
Provides viscosity without needing salt or synthetic thickeners.
Substitutions:
- Xanthan gum (slightly different texture, more “snotty”)
- Hydroxyethylcellulose (more professional feel, less drag)
Disodium Laureth Sulfosuccinate
What it does:
- Primary cleanser
- Removes dirt and oils
Why it’s used:
It’s a gentle, sulfate-free surfactant that still provides good cleansing.
Substitutions:
- Sodium Lauroyl Sarcosinate
- Sodium Cocoyl Isethionate (liquid form only)
Cocamidopropyl Betaine
What it does:
- Secondary surfactant
- Reduces irritation
- Boosts foam
Why it’s used:
Balances the formula to make it milder and more skin-friendly.
Substitutions:
- Coco Betaine
- Lauryl Betaine
Lauramine Oxide
What it does:
- Foam booster
- Helps thicken surfactant systems
Why it’s used:
Improves lather and gives the formula a richer feel.
Substitutions:
- Cocamide MIPA (less mild)
- Additional CAPB (not a direct replacement, but helps)
Glycol Distearate
What it does:
- Pearling agent (creates milky appearance)
- Adds creaminess and body
Why it’s used:
Gives the hand wash a luxury, store-bought look and feel.
Substitutions:
- Opacifying agents (like EGDS blends)
- Omit for a clear formula
- Omit for no heat formula
Sweet Almond Oil
What it does:
- Light conditioning
- Improves after-feel
Why it’s used:
Adds a small amount of softness without making the formula greasy.
Substitutions:
- Jojoba oil (lighter, more stable)
- Sunflower oil (budget-friendly)
Polysorbate 80
What it does:
- Solubilizer (keeps oil mixed in water)
Why it’s used:
Prevents separation and keeps the formula stable.
Substitutions:
- Polysorbate 20 (better for fragrance, weaker for oils)
- PEG-40 Hydrogenated Castor Oil
Fragrance Oil
What it does:
- Adds scent
Why it’s used:
Improves user experience and makes the product more enjoyable.
Substitutions:
- Essential oils (use at safe levels)
- Fragrance-free option
Liquid Germall Plus
What it does:
- Broad-spectrum preservative
Why it’s used:
Prevents mold, yeast, and bacterial growth.
Substitutions:
- Optiphen
- Geogard ECT
- Phenoxyethanol blends
**Always check usage rates and compatibility.
Citric Acid
What it does:
- Adjusts pH
Why it’s used:
Keeps the formula within a skin-friendly pH (5–5.5).
Substitutions:
- Lactic acid
Final Tip
If you substitute ingredients, always:
- Re-check pH
- Watch for changes in thickness
- Test stability over time
Small changes can significantly affect the final product.
How to Make DIY Pearly Hand Soap
Step 1: Make a Guar Gum Slurry
Start by mixing your guar gum and glycerin together until smooth.
This step prevents clumping and helps the gum disperse evenly in water.
Set this aside.
Step 2: Prepare the Water Phase
In a heat-safe container, combine:
- Distilled water
- Your glycerin + guar gum slurry
- Glycol distearate
Each ingredient has a role:
- Water → base of the formula
- Glycerin → hydration + helps texture
- Guar Guar→ helps thicken
- Glycol distearate → gives that pearly, creamy look
Step 3: Heat Until Fully Melted
Place your container into a double boiler.
Heat on medium heat, stirring occasionally.
Continue heating until the glycol distearate is completely melted and the mixture is uniform.
Remove from heat once fully melted.
Step 4: Add Surfactants
In a separate container, combine:
- Disodium Laureth Sulfosuccinate
- Cocamidopropyl Betaine
- Lauramine Oxide
Each one does something different:
- Cleansing
- Mildness
- Foam boosting
Add this mixture into your warm water phase and stir gently.
** Avoid overmixing to prevent bubbles.
** If your mixture looks slightly clumpy, you can place it back on heat for a few minutes until smooth.
Step 5: Add Cool Down Ingredients
Add the:
- Polysorbate 80
- Sweet almond oil
- Fragrance oil
Polysorbate 80 is essential—it allows the oils to mix into the water instead of floating on top.
- You’ll notice we use about the same amount of polysorbate as the total oil + fragrance.
Step 6: Combine
Add your oil mixture into the main batch.
At first, you’ll see the oil sitting on top.
As you mix, it will fully incorporate into the formula.
Step 7: Cool to Room Temperature
Allow the mixture to cool completely before moving on.
This is important because pH changes depending on temperature.
How to Test pH (10% Solution Method)
Step 1: Make a 10% Solution
- 1 g hand soap
- 9 g distilled water
Mix gently.
Step 2: Test pH
Use pH strips or a digital meter.
✔️ Target: pH 5 – 5.5
How to Adjust pH
If your pH is too high:
- Use a diluted citric acid solution
- Add a small amount
- Stir well
- Wait a few minutes
- Test again
Repeat as needed until you reach a skin-safe range.
Step 8: Add Preservative
Once your pH is within range, add your preservative.
I’m using Liquid Germall Plus.
Mix well.
Learn more about preservatives in my What Are Preservatives post.
Step 9: Bottle Your Hand Soap
Pour into a foaming pump bottle.
This formula is too thin for a regular pump.
** Do not fill all the way to the top—leave space for the lid.
Step 10: Use and Enjoy
Pump and enjoy that light, fluffy foam.
Troubleshooting
Too thick → reduce guar gum
Too thin → increase slightly
Oil separating → increase polysorbate 80
Feels drying → increase oil slightly
