With natural ingredients/products, sometimes, we talk about quality like it's a fixed target..It isn't!

With natural ingredients/products, sometimes, we talk about quality like it's a fixed target..
It isn't! When someone says "my product is of the highest quality" the next question should be "to whom?"

Quality is defined by who's buying and what they're going to do with it.
Take a lavender essential oil.

A soap maker doesn't need tight specs on linalool or linalyl acetate percentage or the full chemical characterization. The product is rinsed off in seconds, dermal exposure is minimal and the fragrance performance is what drives the purchase decision. You can work with broader chemotype variation and still deliver a great product.

But that same lavender going into a leave-on serum? Now you're dealing with a higher skin retention. The EU requires allergen declaration (limonene, linalool, geraniol) at very low thresholds, ten times stricter than rinse-off cosmetics. IFRA limits in leave-on products are significantly tighter than rinse-off, and lavandin, often sold as true lavender (lavandula angustifolia, by mistake) can have camphor levels that disqualify it entirely for certain cosmetic applications. A slight shift in chemotype or harvest batch cross-contamination could push you out of compliance.

And if for example an extract (different from essential oil) is going into a pharmaceutical product? You're in pharmaceutical-grade territory, meaning you must comply with the USP (United States Pharmacopeia) or EP (European Pharmacopoeia), the official compendiums that define the strictest purity and identity standards. Very high purity, full batch traceability, GMP-certified facilities, HPLC (and even GC-MS) verified actives.

The same logic applies across categories:
→ A rosemary extract for food flavoring needs GRAS/food-grade status and low pesticide residues (if non-organic). For a perfumery application, what matters is mostly the aromatic profile and fixative properties, the compliance framework is entirely different.
→ An extract for a food supplement brand needs that certain chemical compounds are standardized (chemical profile matters) and heavy metal testing among other types of testing. For a cosmetic claim, the actives profile matter and batch consistency matter but it matters even more a rigorous report of skin safety data and allergens list.

The ingredient doesn't change.
The buyer's world does.

This is why I always say: before you quote a spec, understand the application. Before, as a supplier, of sending your CoA, you need to understand what product is the buyer selling.
Quality is not a grade or fixed. It's a fit 🌱 Quality depends on to whom I'm selling.
