DIACETYL

Description

Diacetyl, also known as 2,3-butanedione, is a organic compound with the molecular formula C4H6O2. This ketone is naturally occurring in various foods and is synthetically produced for use in cosmetic and personal care products. In skincare formulations, diacetyl serves as a flavoring agent and fragrance ingredient, imparting a buttery or creamy scent to products.

Despite its pleasant aroma, diacetyl has been associated with potential health concerns when inhaled in large quantities, particularly in industrial settings. However, its use in topical skincare products is generally considered safe at low concentrations. The Cosmetic Ingredient Review (CIR) has evaluated diacetyl and found it to be safe for use in cosmetics when formulated to be non-irritating.

In skincare, diacetyl is primarily used in lip products, such as lip balms and lipsticks, to enhance the sensory experience. It may also be found in body lotions and creams as a fragrance component. When formulating with diacetyl, it's crucial to adhere to recommended concentration limits and consider potential sensitivities in certain individuals. As with any ingredient, patch testing is advisable for those with sensitive skin or known allergies.
