Answer:
Option - allergy is the answer.
Explanation:
- There are three types of ointment bases:
- oleaginous (greasy) bases - water repellent, water-absorbing bases - greasy but allows absorption of water and water-miscible bases - water-soluble bases.
- To evaluate an ointment these are the parameters that are taken into consideration are colour, odour, pH, hardness, appearance, viscosity measurements, and spreadability.
- Important tests to evaluate pharmaceutical ointment formulations in accordance with the mechanical evaluation parameters like viscosity, spreadability, and homogeneity.
- Those ointments which result in nearly pH 6.8± 1 indicate better chemical compatibility of ointments for the skin.
Hence, allergy is not an evaluation parameter.
