Question

12. The HLB scale range for lipophilic
surfactants is:
A 2 to 9
B 9 to 16
C. 16 to 20
D. Above 20​

Answer 1

Answer:

The HLB scale range for lipophilic surfactants is 2 to 9.

Explanation:

• HLB stands for Hydrophilic-Lipophilic balance.

• The Hydrophilic-Lipophilic balance (HLB) of a surfactant refers to the measure of the degree to which it is hydrophilic or lipophilic.

• This is used to describe surfactants i.e. the balance of the size and strength of hydrophilic (water-loving) and lipophilic (lipid-loving) or hydrophobic moieties of a surfactant molecule.

• The HLB value ranges from 0 to 20.

• For a lipid soluble or lipophilic surfactant, HLB value lies below 10 or between 0 to 9.

Hence option  A. is correct.
