Blending Essential oils by the fragrance pyramid, THE CONNECTION BETWEEN AROMA, EMOTIONS & MEMORIES

If you’re looking to create a perfect perfume blend, one technique for blending essential oils is the fragrance pyramid. The fragrance pyramid is composed of three fragrance notes: top, heart, and base. By working with the fragrance pyramid, you’ll be able to balance the scent of your blend and create a lovely aroma for your aromatherapy fragrance and therapeutic blend.

Understanding the Fragrance Pyramid and Note Classification

The concept of a fragrance pyramid—in which different smells are arranged in levels according to their predominance and intensity—is used by perfumers around the world.

The fragrances are divided into three categories based on how long their molecules take to evaporate. This allows for a structured layering of scents, with each note playing a specific role in the overall fragrance profile.

A fragrance’s scent is composed of three layers: the top notes, the heart notes, and the base notes. The top notes are the initial smell that hits your nose, the heart notes are the main body of aroma that hangs around for a while, and the base notes are the lingering odour that emerges during the dry-down. The fragrance pyramid is a way to categorize and understand these layers of scent in a fragrance.

The Fragrance Pyramid: Top, Heart, and Base Notes 

Top Notes: Small, Light Molecules that Create the Initial Impression 

The top notes are the small, light molecules that create the initial impression of a fragrance. They consist of refreshing scents that evaporate quickly. These ingredients are known for being volatile, light, and fresh. However, because they evaporate quickly, top notes don’t last as long as other notes in a fragrance.

Examples of top notes in fragrances, particularly citrus oils, include:

These scents are part of the small, light molecules that create the initial impression of a fragrance. They are refreshing, volatile, light, and fresh. However, due to their quick evaporation, top notes do not last as long as other notes in a fragrance.

Mid (Heart) Notes: Giving the Fragrance Character and Intensity 

Mid notes, also known as heart notes, are responsible for giving a fragrance its character and intensity. They start to develop within 10 minutes of application and can linger on the skin for up to 3 hours.

Compared to top notes, mid notes have a more soft and rounded scent. They play a crucial role in masking any initial unpleasant impression of the base notes, which become more pleasant over time. Initially, both top and mid notes are present simultaneously, but as the scent matures, the middle notes become more dominant. Overall, mid-notes are essential for creating a well-rounded and balanced fragrance.

Examples of mid (heart) notes in fragrances include:

  • Rose
  • Lavender
  • Clary Sage
  • Geranium
  • Tea Tree
  • Chamomile
  • Ylang Ylang
  • Juniper
  • Thyme

These are herbaceous scents that contribute to the character and intensity of a fragrance.

Base Notes: Providing Depth, Balance, and Grounding to the Overall Scent 

Base notes of a fragrance add depth, balance, and grounding to the overall scent. They typically appear within 30 minutes of application and can last for several hours, providing body and longevity to the fragrance. These essences are rich and robust, serving as a fixative note to anchor the other notes of the scent.

As base notes tend to have a stronger and longer-lasting scent, they create a foundation on which other notes can be built. They are crucial in crafting a fragrance that is long-lasting and memorable.

Examples of base notes in fragrances, specifically woods and balsam, include:

  • Vetiver
  • Patchouli
  • Myrrh
  • Sandalwood
  • Benzoin

These essences contribute to the depth, balance, and grounding of a fragrance. They have rich and robust aromas that provide body and longevity, and they serve as a fixative note to enhance the overall scent.

Tips for Blending Fragrances

To create a well-balanced fragrance blend, it is essential to consider how the scent evolves over time. One effective way to do this is by evaluating the fragrance as it evaporates into the air. This helps in understanding the various stages of the blend and making necessary adjustments.

When blending fragrances, start by selecting the scents you want to combine. While you have the freedom to choose any combination that appeals to you, it is often recommended to keep the blend simple or opt for complementary scents. For instance, lavender and mint are both popular choices with pleasant aromas. Alternatively, you can experiment with contrasting scents to create a unique and unexpected combination. An example would be mixing lavender with rosemary.

Here are a few examples of fragrance pyramid blends:

Floral Blend:

Top Note: Bergamot
Middle Note: Rose
Base Note: Patchouli

Fresh Blend:

Top Note: Grapefruit
Middle Note: Basil
Base Note: Cedarwood

There are countless possibilities for fragrance pyramid blends. Experimenting with different combinations will help you discover unique scents that you love.

Testing and Adjusting Your Blends: Creating Unique and Personalized Scents 

To test small amounts of your blend, you can use perfume blotters or cotton balls. These tools allow you to sample the scent without having to apply it to your skin. This is especially useful when working with strong or unfamiliar scents, as it can help you identify any potential issues or imbalances in the blend. Overall, blending fragrances takes practice and patience. By taking the time to test and adjust your creations, you can create unique and personalized scents that are truly one-of-a-kind.

I hope these examples of fragrance pyramid blends have inspired you to explore combinations and create unique essential oil blends that make you feel happy and uplifted. By experimenting with different scents and notes, you can create your own signature fragrance that suits your personality and style. Have fun playing with different fragrance blends!
