Blending essential oils is both an art and a science. The 30/50/20 rule is a popular guideline used by aromatherapists and DIY enthusiasts to create balanced, harmonious blends. This rule divides the composition of a blend into 30% top notes, 50% middle notes, and 20% base notes, ensuring your creations are well-rounded and delightful from the first impression to the lingering finish.
Understanding the Notes
- Top Notes (30%)
- These are the lightest and most volatile oils.
- They are the first to evaporate and provide the initial impression of the blend.
- Often refreshing, uplifting, and energizing.
- Middle Notes (50%)
- Known as the “heart” of the blend, these oils form the core aroma.
- They provide balance and connect the top and base notes.
- Generally, they are well-rounded and have moderate staying power.
- Base Notes (20%)
- The heaviest and most long-lasting oils.
- They add depth, richness, and anchor the blend.
- Base notes are often grounding and calming.

Tips for Combining Essential Oils
Creating a blend that smells amazing and serves its purpose involves more than just following the 30/50/20 rule. Here are some tips:
- Complementary Scents:
- Citrus oils (top notes) like Lemon and Bergamot pair beautifully with herbal middle notes like Rosemary and floral base notes like Sandalwood.
- Balancing Strengths:
- Strong scents (like Peppermint or Ylang Ylang) should be used sparingly to avoid overpowering the blend.
- Purposeful Blends:
- Relaxation: Lavender (middle), Frankincense (base), and Bergamot (top).
- Energy Boost: Peppermint (top), Rosemary (middle), and Lemongrass (middle).
- Test Before Committing:
- Blend small batches first. Start with 10 drops total and adjust proportions as needed.
