Using Bergamot Essential Oil in Shampoo and Face Wash: Scent and Safety

Here are the answers to your questions regarding the use of Bergamot Essential Oil in shampoo and face wash:

1. Percentage for scent in shampoo: It is recommended to start with 1-3% of Bergamot Essential Oil in your shampoo formulation to achieve a noticeable scent.
2. Scent longevity in shampoo: The scent from essential oils can last for a long time in shampoo, especially if the product is stored in an airtight bottle that prevents easy air exchange.
3. Use in face wash and eye irritation: Bergamot Essential Oil belongs to the citrus group of oils.
