Using the correct fragrance dosage is essential to achieve the desired scent profile, ensure consumer safety, and maintain product stability. Proper guidelines vary depending on the type of product, formulation, and intended use.
General Principles of Fragrance Usage

- Regulatory Limits: Always adhere to cosmetic and regulatory standards for maximum fragrance levels.
- Skin Sensitivity: Use lower concentrations in products for sensitive skin.
- Product Type: Different formulations require different fragrance loads for optimal scent and performance.
Fragrance Dosage Guidelines by Product Type
