1. 1. Essential Oil Usage Standards:

• • The fragrance must be composed entirely of 100% pure natural essential oils without artificial fragrances, diluents, or non-natural ingredients.
  • Participants may freely choose the types and quantities of essential oils, but the formula must include a complete fragrance structure with top, middle, and base notes.

1. 2. Perfume Type and Concentration:

• • Perfume type: Eau de Parfum (EdP) to ensure usability and professional quality:
  • Essential Oil Concentration: 10%-15%.
  • Alcohol Proportion: 85%-90% of the total perfume volume, used to dilute essential oils, enhance diffusion, and prolong scent retention.

1. 3. Fragrance Layering:

• • Top Notes (15%-30%): The initial, light, and fresh impression of the fragrance.
  • Middle Notes (30%-50%): The core body of the fragrance, providing depth and character.
