Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the chemical structure?Ring-shaped organosilicon compounds with repeating siloxane units
2. What is the physical property?High volatility, facilitating evaporation and use as solvents
3. What are cyclosiloxanes and why do they disappear into the air?They are tiny ring-shaped silicone molecules that can easily turn into gas because they are light and have weak forces between them.
4. How do cyclosiloxanes help make cosmetics feel smooth?They spread easily and evaporate quickly, leaving a smooth, non‑greasy finish on skin and hair.

Organosilicon Chemistry: The branch of chemistry dealing with compounds containing silicon-carbon bonds.
Photodegradation: The breakdown of a substance caused by exposure to light, especially ultraviolet radiation.
Siloxane: A functional group or polymer containing repeating silicon-oxygen (Si-O) units.
