A certification is an independently verified standard with documented criteria — EPA Safer Choice, ECOCERT, ISO 9235, Clean at Sephora, and IFRA 51 are real certifications maintained by independent bodies. A 'clean' or 'non-toxic' marketing claim has no agreed-upon definition and isn't independently verified. Stock Fragrance ties every claim we make to a specific certification with verifiable criteria — never to vague marketing language.

There's no real limit. Every certification has its own criteria, so the same formula might pass one and fail another — and those criteria change continuously. A single Stock Fragrance oil can carry 25+ verified compliance attributes depending on its formulation, from EPA Safer Choice, ISO 9235 (plant-based), and ECOCERT to Clean at Sephora and other retailer standards; the full list for each oil is on its product page's Documentation tab. For catalog oils, we create first and verify after — the fragrance is never designed around a checklist. For custom projects, we work to the specs of your brief; just keep in mind that the more certifications required, the more the perfumer's palette is restricted, which can limit what's achievable olfactively.

Certifications are not self-claimed — each is defined and administered by its issuing body, and every claim on a Stock Fragrance oil is traceable to that body's criteria and documentation. But they don't all work the same way: some are pass/fail based on ingredient lists, others depend on the levels of specific ingredients in your end product, and many — like EPA Safer Choice or EWG — are only available at the product level. In those cases the oil itself isn't certified; it's formulated to pass when you submit your finished product for certification.

Certifications are typically issued at the finished-product level, so we don't certify oils. What we do is pre-screen each formula against the certification's published criteria to ensure it will pass should you choose to certify your product. "Compliant" on this page means exactly that: the oil has been verified against the standard's criteria, so the fragrance won't be the reason a product-level certification fails.

That's really up to what matters most to your brand. Every certification measures something different, and the same oil can pass one and fail another — so there's no universal ranking. Choose the standards that matter most for your positioning, your retail channel, and your market, then select oils verified against those. Not sure how to approach it? Book a consultation and we'll help you map the right standards to your product and channel.

It can — so it's always best to check with the specific certification. Some certifications are pass/fail based on the ingredient list; others depend on the final levels of specific ingredients in your finished product, which means your dosage and the rest of your formula matter too. Certifications are updated and changing continuously, and we conform to the most recent standards — which is why compliance is always verified against the current edition of each one.

No — our checks are free. Pre-screening is built into how we formulate, and compliance documentation is posted on each product page at no charge. Certifying your finished product is a different matter: issuing bodies charge for product-level certification, sometimes a lot, so factor that into your plans — always check with the issuing body for details.

Check with the issuer. Some standards on this page are international (ISO 9235, IFRA), while others are tied to a specific market or regulator (EPA Safer Choice, California Prop 65). Whether a claim carries weight in another market is the issuing body's call — confirm with them before relying on it for export.

Each product page has a Documentation tab with that oil's available documents — typically the SDS and IFRA 51 Regulatory Data Sheet, plus additional statements depending on the oil — downloadable individually. Available documents vary by fragrance. For consolidated documentation packages, custom compliance statements, or specific cert letters, use the Document Request form.

We don't certify anything ourselves — certification is always the issuing body's role. What we do is pre-screen each formula against a certification's published criteria, so you know which certifications your product could pass if you apply. Separately, our manufacturers hold their own facility-level certifications (ISO 9001, GMP, etc.), so both the formula and the process behind it are documented.
