What is the ideal pH for a cleanser formulated with sodium lauryl ether sulfate?
pH 6.5-7.5
pH 4.5-5.0
pH 3.5-4.5
pH 9.5-10
Homework Answers
Sodium lauryl ether sulfate is a kind of surfactant commonly used in shampoos , soaps , detergents etc.
All detergents and soaps are basic in nature.
If the pH lies in the range 0 to 6.9 then it is acidic.
If pH is 7 then it is neutral.
If pH lies in the range 7.1 to 14 then it is basic.
Ideal pH range of cleanser must be basic.
Ideal pH range is 9.5 to 10
Answer -- 9.5 to 10
