Question

What functional groups of the emulsifying agent provide the hydrophilic character? Do these groups affect the pH?

Answer 1

Following this question....

Answer 2

Answer:

The polar groups are the ones that provide the hydrophilic character.

Explanation:

In an emulsifying agent, there will be always a part that is hydrophyllic (the polar part) and another part that is lipophyllic (the non - polar part). Depending the proportion of each group the emulsifying agent is consider with a value that goes from 0 to 20, that means, if is more useful to dissolve water into oil or the other way around.

Since in this chemical groups, there is a lot of charges, depending in the reaction the pH could change a little bit by the release of positive or negative charges of the emulsifying agent.
