The gap nobody warns you about

You know your ingredients.
But do you know your formulation science?

Most independent natural skincare makers are deeply ingredient-literate. They know their oils, their extracts, their hydrosols. They care about what goes on their customers' skin. But there is a gap between knowing your ingredients and formulating safely.

01
"I thought Vitamin E was protecting my formula."
Vitamin E is an antioxidant — it protects oils from rancidity. It does nothing against bacteria, yeast, or mould.
02
"I had no idea lavender has three EU allergens I must declare."
From July 2026, three components of lavender must appear individually on your EU label. CEdermalab catches this automatically.
03
"Nobody told me aloe vera juice counts as water in my formula."
Any formula containing aloe, hydrosols, or glycerin above 10% needs a validated preservative system. The safety checker flags this immediately.
04
"I've been selling in Canada without filing a CNF."
Every cosmetic sold in Canada must be notified to Health Canada within 10 days of first sale. CEdermalab covers Canadian regulations in full.
05
"I can't afford a cosmetic scientist but I need to get the science right."
The AI Science Advisor answers formulation questions in the context of your actual formula — pH, preservatives, actives, and compatibility.
06
"My INCI list order isn't right — but I don't know what right looks like."
CEdermalab generates your full INCI declaration automatically in correct regulatory descending order, with allergens flagged separately.
What CEdermalab does

Everything a natural formulator
needs in one place

🌸
EU Allergen Scanner — 2026 Ready
All 82 allergens from Commission Regulation (EU) 2023/1545 coded in. Add lavender and it flags Linalool, Linalyl Acetate, and Camphor. Add ylang ylang and it catches six allergens at once. Scans in real time as you build.
🛡️
Real-Time Safety Checker
The moment you add a water-phase ingredient without a preservative, an alert fires. Every time. Explicitly separates antioxidants from preservatives. pH compatibility guide for every major active. No formula goes unsafe unnoticed.
⚗️
Phase-Organised Formula Builder
Water, Oil, Cool-down, and Active phases. Live percentage calculator, batch gram weights, QS auto-fill, and full INCI declaration in correct regulatory descending order. Export to CSV.
🌿
Natural-Only Ingredient Library
123+ ingredients across 10 tabs. Every ingredient is plant-derived, mineral, or fermentation-based. Zero synthetics. Usage rates, phase guidance, and EU/UK/US/Canada regulatory limits for every card.
🤖
AI Science Advisor
Ask it anything about your formula. It knows your current ingredients and answers in context — why you need a challenge test, what pH your niacinamide needs, how to substantiate a brightening claim.

Commission Regulation (EU) 2023/1545 · Deadline 31 July 2026

Lavender triggers 3.
Ylang ylang triggers six.
Is your formula compliant?

The EU has expanded its fragrance allergen list from 26 to 82. Every one of them is naturally occurring in popular essential oils. If you sell in the EU or UK and use fragrance ingredients, this deadline affects your labels. CEdermalab scans your formula against all 82 in real time — for free.

Case Study
🌿
Step 1
Build formula phase by phase — Rose Hydrosol, Aloe, Glycerin, Niacinamide, Kakadu Plum Extract, Ferulic Acid, Bisabolol
🚨
Step 2 — Alert
Safety checker fires: no preservative detected in an aqueous formula. Benzyl Alcohol + Dehydroacetic Acid added.
🌸
Step 3
Allergen scanner identifies Benzyl Alcohol (original 26) and Citronellol from Rose Hydrosol (new 2026 allergen)
🚨
What CEdermalab caught: The formulator had added Rose Hydrosol, Aloe Vera Juice, and Glycerin — but no preservative. The safety checker flagged this before the formula was finalised. Without this alert, the product would have been manufactured without antimicrobial protection.
✅
The outcome: Preservative system added. Allergens identified and declared. Full INCI declaration generated in correct regulatory order. Formula ready for safety assessor review and ISO 11930 challenge testing.
