Scent Selection or Creation

We offer you a wide range of options to choose from or design a unique olfactory identity that transforms your spaces and emotions. Our collection of 65 aromas, created by renowned perfumers, encompasses a variety of emotions and olfactory notes. For example, in our "Self Confidence" collection, the 1.1 Luxury Drive aroma takes you to the roar of the engine, the feel of leather-wrapped steering, and the thrill of speed. Each aroma in our collection is designed to evoke unique and vivid emotions. It's the ideal choice for small to medium-sized clients seeking variety and a proven solution to enhance different environments. You can select these aromas with the assistance of our sensory architects and our App, The Aroma Trace, using an artificial intelligence test that determines which aroma best suits your personality and mood. To go a step further, we can conduct neuromarketing studies to measure the impact of scent on brain functions and emotions. For larger clients and BTL activations, we offer the creation of exclusive olfactory identities. We collaborate closely with you to understand your goals and brand, crafting personalized aromas that align with your identity and create memorable experiences for your audience.

Process 01

We initiate the process by immersing ourselves in a virtual reality presentation where we travel to different environments through scent. Later we immerse in the essence of the client's brand. This involves a comprehensive understanding of their values, objectives, key audience, and the specific emotions they wish to highlight. We maintain a holistic approach to ensure that the olfactory identity is a genuine extension of the brand.

Process 02

We then use our Scent Briefcase with 65 fragrances to determine which fragrance integrates best with the overall brand identity. We consider elements such as the logo, slogan, architecture, space design, corporate colors, and the brand's personality. Based on this process we gift the client mouillettes with the preferred scents and we pick one from our collection or move on to scent creation if the client qualifies.

Process 03

In the case of olfactory creation, our highly skilled and expert team of perfumers meticulously creates 3 to 5 initial aroma samples designed to reflect the brand's values and attributes. Throughout this process, we ensure that each aroma complies with the highest ethical standards and the regulations set by the IFRA.

Process 04

In the case of olfactory creation, we facilitate the testing of these samples with the client using a Sensory Box format. Each sample is presented through a unique video with a QR code, allowing decision-makers to experience the olfactory sensations and participate in a survey at the end to select their favorite aroma. Optionally, we conduct neuromarketing studies to identify the emotions evoked by the aromas in the audience.

Process 05

Based on client feedback and test results, we make adjustments and refine the aromas as necessary. Furthermore, we tailor the aromas for nebulization and prepare them for final testing at specific locations.

Process 06

Once the client selects the final aroma, we strategically implement it in their spaces. Over time, we provide ongoing monitoring and support to ensure that the olfactory identity remains effective and aligns with the brand's evolving needs.

What are the benefits of olfactory marketing in the hotel industry?

Olfactory marketing in hotels offers several significant benefits. Firstly, it contributes to creating a unique and memorable experience for guests, establishing an emotional connection with the brand. Additionally, strategically using scents can positively influence the perception of the environment, enhancing the hotel's image and creating a sense of well-being. Customer loyalty is also a benefit, as pleasant aromas can leave a lasting impression, encouraging guests to return. In summary, olfactory marketing not only adds a distinctive element to the hotel's brand but also enhances customer satisfaction and strengthens the property's unique identity.

What are the most commonly used scents in hotels to enhance the guest experience?

In hotels, commonly used scents often include fresh fragrances such as lemon, lavender, mint, or eucalyptus, conveying a sense of cleanliness and relaxation. Warm notes like vanilla, cinnamon, or wood are also employed to create cozy atmospheres. The specific choice of scents may vary based on the hotel's identity and style, always aiming to create a unique and pleasant sensory experience for guests.

Are the scents used in hotels safe for the health of guests?

Yes, the scents used in hotels are designed with safety in mind. All aromas comply with the regulations set by the International Fragrance Association (IFRA). Additionally, each aroma employed in the hotel has a safety data sheet detailing its components, ensuring that it meets the established standards of quality and safety. This approach guarantees that guests can enjoy a pleasant olfactory experience while maintaining a safe environment for their well-being.

In which areas of hotels is olfactory marketing commonly utilized?

Olfactory marketing is typically employed in various areas of hotels to enhance the overall guest experience. Commonly scented areas include hotel lobbies, reception areas, hallways, and guest rooms. Some hotels also extend the use of fragrance to specific amenities such as spas, fitness centers, and even conference rooms. The strategic use of scents in these spaces aims to create a welcoming and memorable atmosphere, contributing to guests' overall satisfaction and enjoyment during their stay.

What types of diffusers are commonly used in hotels?

In hotels, various types of diffusers are employed in different areas to achieve effective fragrance distribution. For spacious areas like lobbies, air stream diffusers are often used to disperse scents evenly. In smaller spaces like bathrooms and offices, trace mist diffusers are commonly employed for more localized diffusion. Additionally, in guest rooms, home fragrance diffusers such as reed diffusers are preferred for a personalized and pleasant experience. In large, non-public areas, diffusers like the "Beasty" can be installed through the air conditioning system, enabling powerful and efficient fragrance diffusion to create consistent atmospheres throughout the establishment. This diversity of diffusers allows for a tailored approach to fragrance in each corner of the hotel.

Do you offer exclusivity in the development of olfactory identity for your clients?

Yes, we provide exclusivity in our olfactory development contracts. To clients for whom we create a unique olfactory identity, we guarantee exclusivity throughout the duration of the contract. This means that we commit not to offer the same fragrance to any other client during the agreed-upon period. This measure ensures that the olfactory identity crafted for a client is unique and distinctly reflects the desired brand or environment without duplicates in other locations or establishments.

How long does it take to develop a custom fragrance?

The process of developing a custom fragrance typically takes between 1 and 2 months. This timeframe encompasses the meticulous search for the perfect chemical blend that aligns with the desired identity, ensuring it adheres to our strict ethical code. Additionally, time is dedicated to crafting multiple samples to guarantee the fragrance is exceptional. Once the samples are completed, they are sent to the client for evaluation, ensuring the final fragrance is entirely satisfactory and unique for their specific application.

Are your fragrances natural?

We offer a variety of aromas, some of which are completely natural and hypoallergenic, perfect for sprays and home products. However, it's important to note that essential oil fragrances require a solvent in their chemical composition for diffusion. There is no natural solvent that is free from CMR (carcinogenic, mutagens, reprotoxic chemicals). Therefore, our fragrances contain a carefully balanced combination of natural and synthetic ingredients.

The inclusion of synthetic ingredients helps us limit the use of respiratory allergens and reduce sensitivity to fragrances without compromising olfactive quality. We strive to maintain a balance between quality and sustainability in our formulas. Furthermore, all our fragrances come with IFRA (International Fragrance Association) certificates, ensuring compliance with international safety and quality standards.
