Fragrance Usage Guidelines in Skincare and Hair Products

The appropriate percentage of fragrance to use in cosmetic products depends on the type of product and the area of application. Here are some general guidelines:

• Face Products: For products applied to the face, the recommended fragrance concentration is typically lower due to the skin's sensitivity. A common range is 0.1% to 0.5%.
• Body Products: Products applied to the body can generally tolerate a higher concentration of fragrance. A typical range is 0.5% to 1%, but can sometimes go up to 2% depending on the fragrance and product type (e.g., lotions, creams).
• Hair Products: The usage rate for hair products varies. For rinse-off products like shampoos and conditioners, the range is often similar to body products, around 0.5% to 1%. For leave-on hair products, a lower concentration, similar to face products, might be preferred, around 0.1% to 0.5%, to avoid potential scalp irritation or buildup.

These are general guidelines, and the optimal percentage can vary based on the specific fragrance compound, its intensity, regulatory restrictions, and the target consumer's sensitivity. Always start with a lower concentration and test for stability and skin compatibility.
