What is Saponification? Structure and Action of Soaps and Detergents // HSC Chemistry

In this video we will be discussing saponification – production of soaps from triglycerides. The video also explores the structure and action of soaps and various types of synthetic detergents, as well as their advantages and disadvantages.

• investigate the structural formulae, properties and functional group including:
– esters

• investigate the structure and action of soaps and detergents

What soaps? What are detergents? Soaps and detergent comparison and discussion. How to produce soaps from fats? What is saponification? What are the different types of detergents?

There is a small mistake in this video – the systematic name of glycerol is 1, 2, 3-propantriol (not 1, 2, 3-tripropanol). Sorry for the confusion.

Great video !!! Few questions for you if you don't mind.

1) Structurally, soaps and detergents are so similar but perform differently, why ?
- Is it just the hydrophilic group being different that makes this difference.
- Are there other compounds present which are responsible for these differences?

2) What makes synthetic non-biodegradable, despite similar structure ?
-Isn't the hydrophobic tail the same, so is it because of the hydrophilic side?

3) Also, what makes the charge on the hydrophilic head (anionic or cationic or non-ionic) make such a difference in terms of their applications/uses ?

4) Generally speaking, which is harsher on skin ?
- I'm assuming detergents.

Thank You

@3:02 what's the difference between OH and HO?

Good job.. I like to know about chemistry of rubber
