1. 1. Competition Rules

(1) Roll-On Essential Oil Formulation Rules

1. 1. Essential Oil Usage Standards:

• • The fragrance component must consist of 100% pure natural essential oils, with no artificial fragrances or non-natural ingredients.
  • Participants may freely select the types and quantities of essential oils but must ensure a complete fragrance structure with top, middle, and base notes.

1. 2. Roll-On Essential Oil Concentration

• • The total essential oil concentration must be maintained between 3%-5% to ensure safety and efficacy.
  • The carrier oil must be a natural plant-based oil (e.g., sweet almond oil, grapeseed oil, coconut oil).

1. 3. Fragrance Layering:

• • Top Notes (15%-30%): Light and fresh initial impressions of the fragrance.
  • Middle Notes (30%-50%): Core fragrance notes that create a calming and relaxing atmosphere.
  • Base Notes (20%-40%): Provide lasting depth and stabilize the overall fragrance.

1. 4. Blending and Maturation:

• • Essential oils and carrier oils must be thoroughly mixed. Once blended, the formulation should rest for 24-48 hours to ensure even fragrance distribution and optimal effectiveness.

(2) Roll-On Bottle and Diffuser Stone Design Guidelines

1. 1. Roll-On Bottle Requirements

• • Bottles must have a 10mL capacity and be made of amber glass for light protection and stability.
  • Rollers must be made of stainless steel to ensure smooth application.

1. 2. Diffuser Stone

• • The organizer will provide diffuser stones, sized between 5-7cm in diameter, made from ceramic or plaster material with strong absorption capabilities for stable diffusion of the essential oil fragrance.
  • Each entry will be paired with a diffuser stone labeled with the participant’s number for evaluation.

2. Competition Process

(1) Pre-Competition Preparation

1. 1. Submission of Entries

• • Participants must submit their roll-on essential oil and formula description to the designated location at least 1 hour before the competition begins.

(2) Display and Judging Process

1. 1. Display of Entries:

• • The organizer will arrange entries and formula descriptions based on participant numbers. Staff will extract a small amount of the roll-on oil (approximately 0.05-0.1mL) and evenly apply it to the diffuser stone surface.
  • Judges will evaluate the entries by smelling the diffuser stones based on the established criteria. Participants are not required to perform any on-site operations, as the assessment will be based on submitted entries.

(3) Retrieval of Entries

1. 1. Collection After Judging:

• • Participants may collect their entries at the designated location by 5:00 PM on the competition day.
  • Participants must present their entry numbers for identification. Any unclaimed entries will be handled by the organizer.
