This report presents detailed analytical testing of Salicylic Acid 3% Shampoo, a specialized formulation combining keratolytic action with cleansing properties for scalp conditions requiring exfoliation and scale removal. The assessment was conducted to verify the product's quality attributes, including purity, concentration accuracy, and stability characteristics through comprehensive analytical methodologies for acid-based shampoo formulations that require precise pH control and concentration accuracy to maintain both cleansing efficacy and therapeutic keratolytic effects in challenging aqueous environments.

HPLC, Valoración química

The analytical results show that Salicylic Acid exhibits excellent purity at 98.7%, which is particularly important for an acid-based shampoo formulation where concentration accuracy directly affects both keratolytic efficacy and potential for irritation. The concentration of 2.0 mg/mL indicates precise manufacturing control and excellent product consistency in the challenging shampoo matrix. Impurity levels were minimal at less than 1.3%, consisting mainly of trace hydrolysis products. Chemical titration provided accurate quantitative confirmation of the active ingredient content, ensuring reliable dosing for scalp exfoliation.

Salicylic Acid 3% Shampoo exceeds quality specifications with high purity levels and precise concentration control. The minimal impurity profile confirms excellent manufacturing practices, making this medicated shampoo highly suitable for therapeutic use in scalp conditions requiring keratolytic action, providing effective scale removal and exfoliation while maintaining appropriate cleansing properties and formulation stability throughout product use.
