Olfactorian Review: Features, Community, and How It Compares to Oumamie
An in-depth look at Olfactorian, the invitation-only fragrance formula platform. We analyze its features, community, controversies, and how it compares to Oumamie for DIY fragrance creators.
What Is Olfactorian?
Olfactorian is a web platform launched in 2025 that positions itself as "the open workspace for perfumery." It was created by a Vietnamese hobbyist based in London as a personal digital notebook — a searchable database of fragrance formulas collected from forums, books, and websites across the internet. What started as a side project between the founder and his girlfriend eventually grew into a community-driven platform for perfume enthusiasts.
The platform focuses exclusively on perfumes and fragrances. Users can discover formulas, explore aromachemicals and natural materials, and connect with other fragrance creators — from bedroom perfumers to niche professionals.
Key Features
Olfactorian offers several tools for fragrance creators:
- Formula Editor — Create, edit, and organize fragrance formulas with integrated tools.
- Material Library — Access an extensive database of synthetic aromachemicals and natural botanicals, complete with odor profiles.
- Collection Manager — Organize formulas into custom collections.
- LabSpace — A private workspace for developing original fragrances independently or with select collaborators (still in beta).
- Version Control — Listed as "coming soon," this feature would allow tracking changes and reverting to previous formula iterations.
Many of the formulas available on the platform are sourced from well-known industry references such as The Good Scents Company (TGSC) and Bedoukian, giving users access to a wide library of existing compositions.
The Invitation System
Olfactorian currently operates under a beta invitation system. Access is not open to everyone — prospective users must request an invitation through the platform's beta registration page. This creates an air of exclusivity, but it also limits the platform's reach and can be frustrating for newcomers eager to explore fragrance creation tools.
Community and Social Features
One of Olfactorian's distinguishing traits is its emphasis on community and social interaction. The platform encourages perfumers to exchange insights, give feedback on formulas, and discover inspiration from peers. Its tagline — "Open formulas. Open knowledge. Open community" — reflects a vision of collaborative, transparent perfumery.
The founder has described the project as inspired by open-source software development: a place where hobbyists can build on each other's work the way developers collaborate on code. This philosophy of open formula sharing is something we at Oumamie also value deeply, and we appreciate seeing it championed in the fragrance space.
The Winter Challenge 2025
Olfactorian has organized competitions to engage its community. The most notable is the Winter Challenge 2025, run in partnership with BASED, a Madrid-based company that crafts and curates modern perfume bases for DIY perfumers and niche creators.
The competition offered a $900 total prize pool:
| Prize | Amount |
|---|---|
| Grand Champion | $500 |
| Most Creative Scent | $300 |
| Minimalist Prize (fewer than 12 materials) | $100 |
| Honorable Mentions (×2) | $50 each |
Participants were required to use 5–25 ingredients from 150 approved competition materials, including at least one from a curated list of 24 winter-specific materials. Entries were judged on originality, balance, technique, and theme alignment.
However, this partnership raised some eyebrows in the DIY fragrance community. At the time the competition was announced, BASED appeared to be a very young company — some community members questioned whether it was fully operational, casting doubt on the legitimacy and logistics of the prizes. While the competition itself was a creative initiative, the controversy highlighted the importance of transparency when partnering with sponsors in a niche community.
Formula Quality: A Mixed Bag
The quality of formulas on Olfactorian is uneven. Since many are aggregated from various online sources, some are well-researched and accurate, while others contain errors. Community members on Basenotes have pointed out specific inaccuracies — for example, one user found that a published Samsara formula replaced Ambreine Samuelson with generic Ambreine, substituted Methyl Ionone Gamma with Methyl Ionone Alpha, and listed pure substances instead of solutions.
The Olfactorian team has acknowledged these issues, noting that many formulas "need better vetting" and attributions still require work. For beginners especially, this means formulas on the platform should be treated as starting points for experimentation rather than exact, verified references.
What the Community Says
Opinions in the DIY fragrance community are mixed. On forums like Basenotes and Reddit's r/DIYfragrance, users have shared both praise and criticism:
What people appreciate:
- The site is well-designed and easy to navigate
- It aggregates formulas from many sources in one searchable place
- The material library is comprehensive, with links to formulas and source references
- Some describe it as "a Wikipedia of perfumery"
What concerns people:
- Formula accuracy is inconsistent
- Some formulas lack proper vetting or attribution
- The invitation-only system limits accessibility
- Questions around competition sponsor legitimacy
The founder has been receptive to feedback, engaging with the community and working to improve the platform. This openness is encouraging for a project still in its early stages.
Oumamie vs Olfactorian: Key Differences
While both platforms serve fragrance creators, Oumamie and Olfactorian take meaningfully different approaches.
Scope
Olfactorian focuses exclusively on perfumery. Oumamie covers three verticals: perfumes, cosmetics, and aromas (food flavoring). This makes Oumamie a broader tool for creators working across multiple domains of scent and taste.
Target Audience
Oumamie is designed as a practical, professional-grade tool for students, amateurs, and young professionals entering the flavor and fragrance industry. The platform provides a large, technical database of substances — with FEMA numbers, CAS numbers, usage levels, odor profiles, and domain-specific filtering — that enables users to create serious, industry-standard formulas.
Some students find Oumamie's database intimidating at first glance. That's by design: the depth is there to meet the needs of creators who want to grow from hobbyist to professional, with all the reference data they need in one place.
Social Features
Olfactorian places heavy emphasis on social interaction and community building — competitions, open formulas, collaborative development. Oumamie takes a more controlled approach to sharing. Users can share formulas publicly within the platform or privately with selected collaborators, but the focus remains on the formulation work itself rather than social engagement.
Formula Integrity
Oumamie's substance database is curated with technical accuracy as a priority. Rather than aggregating formulas from external sources with varying quality, we maintain a verified database that users can trust for professional formulation work.
At a Glance
| Feature | Oumamie | Olfactorian |
|---|---|---|
| Domains | Perfumes, cosmetics, aromas | Perfumes only |
| Target users | Students, amateurs, young professionals | Hobbyist perfumers, DIY creators |
| Formula source | User-created with verified substance data | Aggregated from forums, books, websites |
| Access | Open registration | Invitation-only (beta) |
| Social features | Controlled sharing (public/private) | Community-first, competitions |
| Database depth | Technical (CAS, FEMA, usage levels, domains) | Material library with odor profiles |
| Variations | Side-by-side formula comparison | Coming soon (version control) |
Conclusion
Olfactorian is an ambitious project that brings a community-first approach to fragrance creation. Its formula aggregation and social features fill a real gap in the DIY fragrance space. However, the uneven formula quality, beta access limitations, and occasional controversies around partnerships suggest the platform is still finding its footing.
For creators looking for a social, exploratory space focused purely on perfumery, Olfactorian offers something unique. For those who need a reliable, technical tool that spans perfumes, cosmetics, and aromas — with a verified database and professional-grade formulation features — Oumamie is built to serve that need.
Both platforms share a belief in open knowledge and accessible fragrance education. The DIY fragrance community benefits from having multiple tools available, each with its own strengths. What matters most is that creators choose the tool that matches their goals — whether that's experimenting with community-sourced formulas or building production-ready compositions with verified data.
