Which preparations contain salicylic acid to break up impactions and kill bacteria?

Antibacterial
Moisturizing
Chemical
Styling

The correct answer is: Chemical

Salicylic acid is well-known for its keratolytic properties, meaning it helps to exfoliate the skin and remove dead skin cells, which can prevent and treat clogged pores and acne. This ingredient promotes the breaking up of impactions in the skin, making it particularly effective for treating conditions such as acne. It also has antibacterial properties, which can help to kill bacteria on the skin surface, further aiding in the reduction of breakouts and promoting clearer skin. While antibacterial preparations do focus on killing bacteria, they may not necessarily contain salicylic acid as the primary active ingredient. Moisturizing products aim to hydrate the skin and are not designed for breaking up skin impactions. Styling products are typically used to enhance hair appearance and do not contain salicylic acid as they target hair rather than skin concerns. Therefore, the correct choice highlights the role of salicylic acid specifically found in chemical preparations that are formulated for exfoliation and acne treatment.
