Common questions

Is my formula kept confidential?
Yes. Your full INCI list and percentages are never published. Only your product’s final NOI score is made public, and only if you opt into certification. We sign NDAs on request.
What standard do you use?
All assessments follow ISO 16128-2:2017 (Natural Origin Index for ingredients). We use the feedstock categorisation and weighted-average calculation method defined in that document.
Can I use the score for marketing claims?
Yes. The NOI score and certificate are designed to support percentage-based “naturally derived” claims, in line with how ISO 16128 is applied in the EU and other markets.
What if I want to improve my score?
Formula assessments include optional reformulation consultation — we identify low-NOI ingredients and suggest higher-NOI alternatives with similar functional profiles.
How long does it take?
Single ingredient analyses typically take 3 business days. Full formula assessments take 5–7 business days depending on complexity and the number of ingredients.
