Quaternium-73 is a potent synthetic preservative with antimicrobial and antistatic benefits. It helps keep acne and dandruff under control by fighting off bacteria on the surface. In a formulation, it prevents microbial growth and increases the shelf life of beauty products. Quaternium-73 is popular in hair care formulations due to its antistatic action; it improves the texture and overall manageability of the shafts. Moreover, this ingredient is valuable as it is highly effective at very low concentrations. Quaternium-73 is commonly found in anti-acne creams, anti-dandruff shampoos, cleansers, and deodorants. It is safe for use but can cause mild irritation if used above the recommended concentrations.

Origin
Quaternium-73 is made by reacting a tertiary amine with an alkylating agent - such as alkyl halide - to form a quaternary ammonium salt. This quaternization process takes place under controlled temperature and pH. Then, iodide ions are introduced to form the final ingredient. Quaternium-73 appears as an odorless, yellow crystalline powder in its raw form. It is purified and standardized for use in cosmetics. The chemical formula of Quaternium-73 is C23H39IN2S2.
