Directions: Read the passage and answer the question that follows.
If you pay close attention to soap advertisements, you may hear of its pH value being touted perfect for human skin. But is there really such a thing? pH (Potential Hydrogen) is defined as the concentration of hydrogen ions in a solution. pH value ranges between 0 and 14. 7 is the neutral point, 0 being the most acidic and 14 being the most alkaline. More importantly, your skin isn’t exactly pH 5.5. It falls in a range between 4.0 and 7.0, depending on factors as diverse as the body part, age, genetics, ethnicity, environment conditions, to list a few. So, are products formulated at pH 5.5 perfect for the skin? The short answer: not really! First, parameters like surfactants, texture and other ingredients indicate a cleanser’s quality, much better than pH alone. Second, though the skin pH rises slightly immediately after cleaning even with plain water, it reverts to its mild acidic pH in an hour. Healthy skin quickly rebalances the ‘acid mantle’- a protective layer over the skin- and is unaffected in the long term by the cleanser’s pH. Skin modulates pH, making skin products function optimally, not just at various pH levels, but in combination with the overall formula. So, why market pH 5.5 products as ‘perfect’? Well, for certain skin types (e.g. oily skin) and certain skin conditions (like acne), an increase in pH can aggravate these skin situations. This might lead to an interpretation of a product needing to be at a 5.5 pH for optimum cleaning. The Bureau of Indian Standards’ (BIS) mandatory guidelines for soap also exclude pH demonstrating that composition is more relevant to safety and mildness. BIS even approves the use of such soaps for a baby’s skin, underscoring their safety under normal usage conditions. Skincare experts around the country have expressed their reservations about the issue of pH being the sole judge of product safety and acid mantle preservation when factors, including but not limited, to plain water may be contributing to the same. Hence, an ideal product is almost impossible to define. So, can we look at this ‘ideal pH’ as the only ideal measure of a cleansing product? The answer: look well beyond pH alone.
Q. Which of the following statement(s) support that soaps with pH 5.5 is not considered ‘perfect’?
(i) the pH of skin isn’t exactly 5.5
(ii) a cleanser’s quality is indicated by surfactants, texture and other ingredients, better than pH
(iii) BIS excludes pH as a character of a good soap and indicates that soaps with any pH does not cause harm to human skin
(iv) for certain skin types, pH is the only thing that needs to be considered while buying a soap.
  • a)
    i, ii and iii
  • b)
    i, iii and iv
  • c)
    i and iv only
  • d)
    i and ii only
Correct answer is option 'D'. Can you explain this answer?
