Question 1

Q: What are the components of Whitfield's ointment?

3% salicylic acid + 6% benzoic acid. ***3% salicylic acid + 6% benzoic acid*** - **Whitfield's ointment** traditionally contains a combination of **3% salicylic acid** and **6% benzoic acid**. - **Salicylic acid** acts as a keratolytic agent, helping to shed dead skin cells, while **benzoic acid** provides antifungal properties. *5% salicylic acid + 10% benzoic acid* - While these concentrations of **salicylic acid** and **benzoic acid** are both used in dermatology for their respective properties, they do not represent the classic formulation of **Whitfield's ointment**. - This higher concentration might be used in other topical preparations but is not standard for Whitfield's. *2% salicylic acid + 4% benzoic acid* - These concentrations are **lower** than the standard formulation of **Whitfield's ointment**. - Using lower concentrations might reduce efficacy for conditions like **tinea pedis** where Whitfield's is often employed. *2% benzoic acid + 4% salicylic acid* - This option reverses the typical higher concentration of **benzoic acid** compared to **salicylic acid** in Whitfield's ointment and uses incorrect percentages. - The specific ratio and concentrations are crucial for the product's intended antifungal and keratolytic actions.
