Let’s be honest, cleansing is probably the most underestimated step in skincare. We focus so much on serums and creams that we forget what really sets the stage: a good, gentle cleanse.
Now, here’s the thing, cleansing isn’t just about removing makeup or grime. It’s about balancing. It’s the moment your skin gets prepped to receive everything else you lovingly apply afterward. But if your cleanser is too harsh or stripping, it’s like starting your routine with a little damage, and your skin has to work overtime just to get back to baseline.
As a formulator, I always say: your cleanser should never make your skin feel tight, squeaky, or irritated. It should feel refreshed, soft, and calm, like your skin just took a deep breath. Whether you’re working on formulations for dry, oily, or sensitive skin, the goal is the same: cleanse without compromise.
In this blog, I’ll walk you through exactly how to create a face cleanser that’s not just gentle, but also nourishing and beautifully balanced. Let’s dive in!
Understanding Your Skin Barrier & Why Harsh Cleansers Hurt
Before we talk about ingredients and formulations, let’s talk about your skin’s superhero: the skin barrier. Think of it like your skin’s personal shield, it’s what keeps the good stuff (like moisture) in and the bad stuff (like pollutants and bacteria) out.
This barrier is made up of lipids, proteins, and cells that work together like a tightly knit wall. When it’s healthy, your skin looks smooth, feels supple, and behaves beautifully. But here’s where many commercial cleansers go wrong: they strip away not just dirt, but the protective lipids too, especially if they’re loaded with strong surfactants or high pH levels.
When the barrier is compromised, you’ll see the signs pretty quickly: tightness, dryness, flakiness, sensitivity, and even breakouts. That “squeaky clean” feeling? That’s actually your skin crying for help.
As a formulator, my job is to respect the skin’s natural structure. That means choosing surfactants that cleanse gently, supporting hydration with humectants, and always, always staying within a skin-friendly pH range (usually around 4.5 to 5.5).
Because real skincare doesn’t just clean, it protects, nourishes, and supports the skin’s natural brilliance.
Key Ingredients for a Gentle Cleanser
Alright, now let’s get to the fun part, ingredients! When you’re formulating a gentle face cleanser, your ingredient list is where the magic (and mindfulness) really begins.
Think of it like crafting a soothing herbal tea, you want it to be calming, effective, and a joy to use. Every ingredient should have a purpose, especially when the goal is to cleanse without disrupting the skin’s natural harmony.
Mild Surfactants (the cleansing heroes)
These are the star players in any cleanser, but we want them to be the gentle kind.
- Coco Glucoside and Decyl Glucoside: Both plant-derived and super mild, perfect for sensitive or dry skin.
- Sodium Lauroyl Lactylate or Disodium/Sodium Cocoyl Glutamate: These offer a soft foam and excellent skin compatibility.
- Capryl/Caprylyl Glucoside: Wonderful for formulations needing a touch of solubilizing action too.
Always aim to blend surfactants for the perfect balance of mildness, cleansing power, and feel. That’s your secret sauce!
Hydrating & Moisture-Retaining Ingredients
Gentle cleansing doesn’t stop at “not stripping”, you also want to add hydration back in.
- Glycerin: A classic and affordable humectant that draws water to the skin.
- Panthenol (Provitamin B5): A skin soother that hydrates and strengthens the barrier.
- Aloe Vera Juice or Extract: Calming, cooling, and beautifully hydrating, plus it aligns with the natural and Ayurvedic vibe.
Skin Soothers
These are especially important for reactive or dry skin.
- Colloidal Oatmeal or Oat Extract: Rich in beta-glucans, oats calm irritation and reduce redness.
- Chamomile Hydrosol or Extract: A botanical soother with anti-inflammatory properties.
- Cucumber Extract: Cooling and refreshing, perfect for sensitive skin blends.
pH Adjusters & Preservatives
Yes, even in a cleanser, these are non-negotiable.
- Citric Acid or Lactic Acid to bring your pH down into that ideal skin-loving range.
- Sodium Phytate or Sodium Gluconate for chelation support.
- Geogard ECT, Dermosoft, or any broad-spectrum preservative system suitable for your formulation style.
When chosen thoughtfully, these ingredients don’t just clean, they care. They respect the skin’s barrier, support hydration, and create an experience your skin will thank you for daily.
Formulator’s Tip: Pairing Surfactants for Mildness + Performance
Here’s a little behind-the-scenes insight from my lab to yours, surfactants work better together. Seriously. One of the biggest formulating mistakes I see is using a single surfactant and expecting it to do everything, cleanse thoroughly, foam beautifully, feel soft, and still be gentle? That’s a tall order for one ingredient.
The secret? Pairing complementary surfactants to balance cleansing power with skin-friendliness and that lovely sensorial experience we all crave.
Let me break it down:
- Start with a primary surfactant, something mild but with decent cleansing ability. Think: Decyl Glucoside or Sodium Cocoyl Glutamate.
- Then, blend in a secondary surfactant to soften the feel and reduce irritation. For example: Cocamidopropyl Betaine or Capryl Glucoside. These help with foam and viscosity, too.
- Want to make your formula creamier or more conditioning? Add in a fatty acid–based co-surfactant like Sodium Lauroyl Lactylate or a touch of a non-ionic emulsifier to support texture.
The result? A cleanser that doesn’t just clean, it caresses. It respects the skin barrier, feels lush during use, and rinses off without that tight, dry after-feel.
Oh, and here’s a bonus tip: always test your blend at different concentrations. Sometimes reducing your total surfactant load to 5–8% (for a face cleanser) gives you better results than loading up too much. Less is more when it comes to gentle cleansing!
How to Make the Cleanser
Now that we’ve explored the why and the what, let’s get into the how. Making a gentle face cleanser is actually a very meditative process, think of it as a mini lab ritual where every phase has its own rhythm and reason.
Here’s a step-by-step method I use when formulating a non-stripping, skin-loving cleanser:
Phase 1: Water Phase
Start with your distilled water or hydrosol base (like chamomile or cucumber for extra soothing power).
→ Add your humectants like glycerin and panthenol here.
→ You can also pre-mix your botanical extracts into this phase if they’re water-soluble.
Heat gently if needed, around 40–45°C, just enough to dissolve.
Phase 2: Surfactant Phase
In a separate beaker, measure and mix your primary and secondary surfactants.
→ For example: Decyl Glucoside + Cocamidopropyl Betaine
→ Stir them slowly to avoid introducing air (hello bubbles 👋🏼).
If using thick surfactants like Sodium Cocoyl Isethionate paste or Sodium Lauroyl Lactylate, warm them slightly to ease blending.
Phase 3: Combine & Blend
Once both phases are ready and around the same temperature, slowly combine the water phase into the surfactant phase, not the other way around.
→ Stir gently with a spatula or use a magnetic stirrer if you have one, this helps maintain a clear, bubble-free consistency.
This is also a great moment to check viscosity. If your cleanser is too runny, you can add a natural thickener like xanthan gum or a gum blend. (Just hydrate it beforehand in glycerin for a lump-free gel!)
Cool-Down Phase
Once the mix cools to under 40°C, it’s time to add your:
- Preservative (like Geogard ECT or Optiphen)
- Essential oils or natural fragrance (if using, optional)
- Chelators or antioxidants (like sodium phytate or vitamin E)
Finally, check and adjust the pH, you want to land between 4.5 and 5.5 for a happy skin barrier. Use citric acid solution to lower it, or sodium hydroxide solution to raise it (if needed).
Bottle It Up
Once you’re happy with the texture and pH, pour your cleanser into a clean pump or flip-cap bottle. Let it sit for 24 hours to see if the viscosity or pH shifts slightly before final labeling.
And voilà! You’ve just made a gentle, balanced cleanser that your skin, and your customers, will love.

Customization Tips for Different Skin Needs
One of the best things about this gentle cleanser base is how beautifully adaptable it is. Once you’ve nailed the core formulation, you can start tweaking it to suit different skin goals, whether it’s calming inflammation, clearing congestion, or giving dry skin a big drink of hydration.
Let’s break it down by skin type:
For Dry or Dehydrated Skin:
Dry skin needs more hydration and barrier support, so we’ll focus on soothing, water-binding ingredients.
- Add more humectants like Sodium PCA or Beta-Glucan (1–2%)
- Boost soothing with a dash of calendula or marshmallow root extract
- Use hydrating hydrosols like rose or lavender in place of chamomile
Optional: Add a small amount of a solubilized light oil (like jojoba) for extra nourishment, around 0.5%.
For Oily or Acne-Prone Skin:
We’re not aiming to “strip the oil”, just balance it while being kind to the skin’s microbiome.
- Swap hydrosol to something like green tea or witch hazel distillate (alcohol-free!)
- Add active botanicals like willow bark extract or niacinamide (up to 2%)
- Essential oil options: A tiny amount (0.2–0.3%) of tea tree or lavender (make sure to test for sensitivity)
You can reduce glycerin slightly if skin feels sticky, oily skin sometimes prefers lighter textures.
For Sensitive or Reactive Skin:
This is where your formulation really needs to feel like a gentle hug.
- Stick to ultra-mild surfactants, you can drop the Caprylyl/Capryl Glucoside if needed
- Go fragrance-free or use a calming hydrosol blend instead
- Add skin barrier superstars like allantoin (0.3–0.5%) or oat beta-glucan
Keep the pH right around 5.0 and avoid overloading the formula with too many actives.
For Mature or Dull Skin:
We’re talking glow and resilience here.
- Add brightening botanicals like licorice root extract or sea buckthorn (oil-soluble, so solubilize well!)
- Include a mild AHA, like lactic acid or a fermented fruit extract, for gentle exfoliation
- Switch panthenol for a mix of panthenol + sodium lactate for a hydration + mild peel effect
Keep everything balanced and gentle, you still want that non-stripping cleanse!
Remember, the base is just the beginning. As a formulator, the joy is in tweaking with intention, always asking: what does this skin truly need, and how can I give it that gently?
Testing & Preservation Matters
Let’s have a little heart-to-heart here: I know preservation and testing might not feel like the glamorous part of formulating, but trust me, this is where your product earns its safety badge.
Even the most beautifully crafted, natural, and skin-loving cleanser can go bad if we skip this step. And because cleansers are water-based, they’re basically a party invite for bacteria, mold, and yeast unless properly protected.
Preservation First – Why It’s Non-Negotiable
Whether you’re making for yourself, your brand, or clients, you must use a broad-spectrum preservative. In our sample formula, I included Geogard ECT, which works beautifully with mild cleansers and plays nicely with pH ranges between 3–8.
Here’s the thing: being “natural” doesn’t mean going preservative-free. It means choosing safe, effective preservation with intention.
If you’re using botanicals, aloe juice, or extracts, they’re incredible for skin benefits, but they also introduce microbial risk. So always balance beauty with science.
Basic Testing to Get You Started
If you’re making this for yourself or small batches, here are a few smart things to do:
- pH Testing: After your cool-down phase, check the pH with strips or a meter. For a face cleanser, aim for 4.5–5.5 to stay within the skin-friendly zone.
- Stability Test: Store your cleanser in 2–3 different conditions (room temp, warm, fridge). Observe for viscosity shifts, separation, or odor change over 2–4 weeks.
- Foam & Feel Test: Use it daily, notice how it feels on the skin, how it rinses, and if the viscosity holds.
If you’re scaling up or going commercial, preservative efficacy testing (PET) and microbial challenge testing are a must.
Testing and preserving well is like sealing your love into the formula. It’s how you show respect for your customer’s skin, and your own hard work.
Conclusion
And there you have it, a complete, skin-loving journey from understanding to formulating your very own gentle face cleanser. Whether you’re crafting this for your brand, your clients, or your own personal routine, remember this: cleansing isn’t just a step, it’s a daily ritual of care.
When we strip away the harsh surfactants, synthetic fragrances, and unnecessary fillers, what we’re left with is something truly intentional. A cleanser that respects the skin barrier, hydrates instead of dehydrates, and nurtures instead of overwhelms.
As a formulator, it’s incredibly empowering to know exactly what’s going into your product, and why. You’re not just mixing ingredients; you’re creating an experience. One that starts the day feeling fresh and ends the night feeling restored.
So keep experimenting. Keep customizing. And always listen to the skin, it’s smarter than we think. When you formulate with gentleness and purpose, trust me, your skin will absolutely thank you.
