Generative AI and Machine Learning in Fragrance Design

Creating New Scent Formulations with Generative AI

Generative AI is reshaping the way fragrances are developed by converting raw chemical data into innovative scent formulas. This technology uses SMILES strings - a standardized system for digitally representing chemical structures - to encode fragrance ingredients as molecular fingerprints. By studying patterns within these fingerprints, AI can uncover statistical connections between molecular structures and the scents they produce.

One standout example of this is the Odor Generative Diffusion (OGDiffusion) method, pioneered by Professor Takamichi Nakamoto’s team.

"As Professor Nakamoto explains, our diffusion network uses mass spectrometry patterns of essential oils to generate new fragrance profiles automatically and accurately".

In 2023, Firmenich, a leading Swiss fragrance house, collaborated with MIT’s Media Lab on Project Oud Mirage. This project used AI to analyze 1,200 natural and synthetic oud-related molecules, resulting in the creation of "Oud Mirage Gamma." The formula skillfully combined affordable natural ingredients with synthetic norlimbanol to mimic the rich depth of artisanal oud. Niche brand Jorum Studio introduced the resulting fragrance, Resinum, to the market later that year.

What’s more, AI-driven platforms can now deliver physical fragrance samples in as little as 48 hours, dramatically cutting down the time needed for development.

Alex Wiltschko, Founder of Osmo, highlights the potential of this technology: "Generation can predict and create entirely new molecules that have never been smelled before, are more sustainable, and solve problems that existing materials can’t, such as toxicity and safety to humans and the planet".

In addition to generating formulas, AI is proving invaluable in refining fragrance designs to align with real-time consumer preferences.

Analyzing Consumer Preferences with Machine Learning

After creating innovative formulas, machine learning steps in to fine-tune fragrances based on shifting consumer trends. This technology excels at identifying hidden patterns in consumer behavior by analyzing diverse data sources, such as social media activity, weather trends, economic conditions, and even music playlists. Natural Language Processing (NLP) tools further enhance this process by translating consumer feedback from platforms like messaging apps and focus groups into actionable insights for perfumers.

For instance, in Q2 2022, Symrise’s AI systems detected a 47% increase in searches for terms like "damp moss", "cold linen", and "unripe pear", fueled by TikTok’s #cottagecore trend. Acting on this insight, the company developed and launched the unisex fragrance "Haven" in just 11 weeks.

Machine learning also plays a crucial role in adjusting fragrances for regional markets. By analyzing linguistic sentiment databases, AI can identify cultural nuances - such as the negative industrial associations of "leather" notes in Seoul - and suggest formula adjustments before launch. These systems can even predict molecular interactions, including how fragrances will adhere to skin or evaporate, with an impressive 92% accuracy. This kind of precision supports the growing consumer interest in personalized fragrance collections, allowing people to curate scents that match their individual tastes.

Companies are already making significant investments in this technology. In June 2025, Unilever allocated $114 million to create an in-house AI-powered fragrance design unit. This initiative combines AI with neuroscience to craft proprietary scents that enhance mood and emotional well-being across its global brands. Similarly, Paco Rabanne used EEG data to measure millennials’ brain activity, identifying ingredient combinations for its "Phantom" fragrance that would evoke specific emotional responses.

Artificial intelligence is reshaping the way fragrance brands source their ingredients, offering real-time insights into environmental impact and ethical considerations. Machine learning now tracks supply chains to identify ingredients linked to endangered species or unsustainable harvesting. These systems also evaluate carbon emissions for each component, helping perfumers choose more eco-friendly options.

For example, DSM — Firmenich introduced the EcoScent Compass platform between 2024 and 2026. This tool evaluates the sustainability of fragrance ingredients in real time, focusing on carbon emissions and environmental impact. It enables the creation of "circular" fragrances designed to meet strict eco-conscious standards. Similarly, platforms like NobleAI’s VIP and Chemcopilot integrate toxicology assessments, ingredient substitutions, and carbon emission tracking into a unified workflow. This approach allows manufacturers to balance sustainability metrics with chemical performance seamlessly.

AI’s predictive algorithms have achieved 96% accuracy in evaluating molecular stability and shelf-life. This ensures that ingredients sourced sustainably can maintain high-quality fragrance performance over time. Additionally, AI systems automate checks for compliance with IFRA standards and suggest sustainable alternatives, significantly cutting down on waste.

Beyond sourcing, AI plays a key role in reducing waste by optimizing formulation processes.

Minimizing Waste Through AI — Optimized Formulations

Traditional fragrance development relies heavily on trial-and-error methods, often requiring months of testing and substantial raw material use. AI is changing this by introducing digital simulations and predictive models that streamline the process. Machine learning tools can now predict molecular stability, volatility, and skin adhesion with over 92% accuracy, reducing the need for physical prototypes and conserving resources.

One notable innovation is Professor Takamichi Nakamoto’s Odor Generative Diffusion (OGDiffusion) model. This system automates scent creation by calculating precise blends of essential oils using mass spectrometry data, eliminating the need for human intervention or molecular synthesis.

AI-driven formulation models have also cut development timelines by 40% to 60%. Tools like Carto can generate compliant and viable formulas in under 90 seconds - an enormous leap compared to the weeks or months required for traditional methods. This efficiency not only preserves rare and costly ingredients like rose and oud but also reduces energy consumption throughout the research and development cycle.

How AI Powers Personalization

AI is transforming how fragrances are tailored to individual preferences. By analyzing a mix of personal data - like demographics, psychological traits, sensory memories, and behaviors — AI creates detailed scent profiles. It maps emotions and experiences to specific molecular attributes, bridging the gap between abstract feelings and tangible fragrances.

Take Jo Malone London, for instance. In December 2025, they introduced an AI Scent Advisor powered by Google Cloud. This tool translates user inputs, like "rainy morning", into personalized fragrance suggestions. The result? A doubling of purchase rates. Another example is International Flavors & Fragrances (IFF), which rolled out ScentChat™ in October 2025. This platform gathers real-time consumer feedback to fine-tune formulations on the spot.

This level of precision naturally extends to customizable fragrances, aligning perfectly with modern consumers’ desire for scents that fit their unique lifestyles.

The Growth of Customizable Fragrances

The push for personalization has evolved into a broader trend: fully customizable fragrances. Consumers are moving away from the idea of a single "signature scent" and instead are curating collections that match different moods, seasons, and events. This shift has fueled demand for mini-sized fragrance containers, which are now selling at three times the market rate. AI-driven customization plays a key role in this surge, as does the appeal of having personalized, portable options.

Platforms like EveryHuman, launched by The Fragrance Shop, take customization to new heights. Using 46 core building blocks, they can create over 500 billion unique fragrance combinations.

"There are 600 perfumers in the world... but it doesn’t mean that you and I can’t design scent and can’t participate deeply in the scent design process",

• Alex Wiltschko, Founder of Osmo.

This trend also ties into the concept of scent wardrobes. Instead of committing to a full bottle right away, consumers often test multiple decants to find their ideal match. While AI helps refine choices by factoring in elements like skin chemistry (pH, temperature, natural oils), physical testing remains crucial to discovering the perfect fit. Together, these personalization trends highlight how AI is revolutionizing both consumer experiences and the fragrance development process.
