🧐 Frequently Asked Questions (FAQ)

Q. What is fragrance concentration or "fragrance load"?

A. Fragrance concentration refers to the percentage of pure fragrance oil relative to the total volume of the final product. This percentage determines the scent's strength and longevity. Higher concentrations result in a stronger, longer-lasting scent.

Q. What is a safe concentration for products applied to the skin?

A. For products that come into direct contact with the skin, such as perfumes or rollerballs, it is crucial to use a safe dilution. While standards can vary, a concentration of 1-2% is generally recommended for beginners to minimize the risk of skin irritation. For sensitive skin or daily use, even lower concentrations (e.g., 0.5-1%) are advisable. Always perform a patch test on a small area of skin before regular use.

📚 Understanding Perfume Concentrations

The concentration of fragrance oil is what defines the type and intensity of a perfume. Knowing the standard categories can help you decide on the target concentration for your DIY project. Here's a general guide:

  • Eau de Cologne (EDC): Typically contains 2-4% fragrance oil. It's light, fresh, and usually lasts for a couple of hours.
  • Eau de Toilette (EDT): Contains 5-15% fragrance oil. This is a very common concentration, offering a balanced scent that is noticeable but not overwhelming, lasting for a few hours.
  • Eau de Parfum (EDP): Contains 15-20% fragrance oil. It is more intense and long-lasting than EDT, often lasting for five to eight hours.
  • Parfum / Extrait de Parfum: The most concentrated form, with 20-30% fragrance oil. It is the most potent and longest-lasting category, with the scent enduring for a full day or more.

When using this calculator, you can aim for these percentages to replicate your favorite type of fragrance.
