1. Competition Objective

This competition evaluates participants’ comprehensive skills in designing fragrance layers, applying aromatherapy techniques, and showcasing creative expression through the formulation of a home sleep-aid roll-on essential oil. Participants are required to design a high-quality personalized aromatherapy formula with proven sleep-enhancing benefits tailored to real-life scenarios.

2. Scoring Criteria

• Fragrance Layering and Balance: Distinctiveness and harmony of the top, middle, and base notes, smoothness of transitions, and overall coherence.
• Blending Precision and Technical Performance: Accuracy in the proportion of essential oils and carrier oils, adherence to blending standards, and consistency and stability of the fragrance.
• Creativity and Expression: Relevance of the formula theme to the sleep-aid purpose, functionality of the amber roll-on bottle and diffuser stone, and completeness and clarity of the formula description.

3. Competition Rules

(1) Roll-On Essential Oil Formulation Rules

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.

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).

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.

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. 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.

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.

4. Competition Process

(1) Pre-Competition Preparation

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. 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. 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.

5. Formula Description Requirements

• Printing Standards: Formula descriptions must be printed on A4 paper, with clear and complete content.
• Content Requirements: Templates can be found in the appendix of the rules document.
