Stabilizers in perfumery are ingredients that help to preserve the fragrance and prevent it from degrading over time. There are several different types of stabilizers commonly used in perfumery, including:
Antioxidants - Antioxidants are used to protect the fragrance from oxidation and rancidity. Some common antioxidants used in perfumery include BHT, BHA, and vitamin E.
Chelating agents - Chelating agents are used to remove metal ions from the fragrance, which can cause the fragrance to degrade over time. Some common chelating agents used in perfumery include EDTA and citric acid.
UV absorbers - UV absorbers are used to protect the fragrance from the harmful effects of UV radiation, which can cause the fragrance to break down and degrade over time. Some common UV absorbers used in perfumery include benzophenone and octocrylene.
The appropriate concentration of stabilizers in a perfume will depend on the specific stabilizer being used, as well as the other ingredients in the formula. In general, stabilizers are used in small amounts, usually less than 1% of the total fragrance formula. The exact concentration will be determined by the perfumer, who will carefully balance the stabilizers with the other fragrance ingredients to create a stable, long-lasting, and high-quality perfume.
