Detergents

Description

Detergents — Chemistry Chapter Presentation Slides: 16 | Audience: High school / early-college chemistry, applied chemistry, or consumer science students | Format: Editable PowerPoint (.pptx) | Series: Chapter 2 of The Chemistry Spirit (Soaps & Detergents) Ever wondered why laundry powder cleans in hard water when soap gives up and leaves scum on the tub? This chapter opens up the bag of detergent and shows what's actually in it — surfactants, builders, and additives — and why each one earns its slot on the ingredients list. Students move from the 1907 invention of Persil, through the anatomy of a surfactant molecule, all the way to a real percentage breakdown of what fills a modern laundry powder. It pairs textbook chemistry with two hands-on activities and enough real-world detail that students will start reading the labels on the shelf at home.
