Waxes
Waxes are organic compounds that are hydrophobic, meaning they repel water. They are long-chain fatty acids that have a variety of uses in nature and industry.
Properties of Waxes:
- Waxes are solid at room temperature.
- They have a high melting point, which makes them useful for coatings and waterproofing.
- Waxes are insoluble in water but soluble in nonpolar solvents.
- They are malleable and can be easily molded into different shapes.
Natural Sources of Waxes:
Waxes are found in various natural sources, including:
- Plants: The leaves and fruits of many plants have a waxy coating to reduce water loss.
- Animals: Bees produce wax to build honeycombs, and some animals use waxes to coat their fur or feathers for waterproofing.
- Minerals: Some mineral waxes, such as ozocerite and montan wax, are derived from natural deposits.
Uses of Waxes:
Waxes have a wide range of applications, including:
- Polishes: Waxes are used in polishes for wood, leather, and metal surfaces to provide a protective and glossy finish.
- Cosmetics: They are used in the production of lipsticks, lotions, and creams for their emollient and protective properties.
- Candles: Waxes, such as paraffin wax and beeswax, are used in the production of candles for their slow-burning properties.
- Food: Some waxes, such as carnauba wax, are used as food glazing agents to provide a shiny coating on fruits and candies.

From Molecules to Organisms: Structures and Processes
Design a solution to a human problem by using materials to imitate how plants and/or animals use their external parts to help them survive, grow, and meet their needs (e.g., outerwear imitating animal furs for insulation, gear mimicking tree bark or shells for protection).
