What it is
Cyclododecyl Formate is a synthetic ester compound used primarily as a fragrance ingredient in cosmetics and personal care products. It is created in a lab by combining cyclododecanol with formic acid, resulting in a clear liquid with a strong, pleasant odor.
How it works
In a cosmetic product, Cyclododecyl Formate works by releasing its aromatic molecules into the air, creating a scent that masks any unpleasant base odors from other ingredients. It does not interact with the skin to provide any functional benefit beyond fragrance.
