Wax
* All wax is made of some combination of wax, resin, and oil
  - waxes contain fats or oils
* Many waxes leave behind a white powdery residue.
* Most wax becomes liquids
  - maintains moisture
  - waxes are either organic or polymer-based
* Some wax comes from bees
  - contains hydrocarbons
  - is produced by prey
  - resembles meals
  - waxes also serve as polishes, and are capable of removing minor paint imperfections
* Some waxes are made for colder weather, some for warm
  - of mineral origin
  - contain herbs or other substances
* are common in nature.
* are esters of fatty acids and long chain alcohols
  - formed from long-chain alcohols and a fatty acid
  - long chain aliphatic acids and alcohols
  - generally blends which contain other ingredients
  - important as waterproofing agents
* are insoluble in water and serve as protective coatings in nature
  - but soluble in organic, nonpolar solvents
  - one of the material which can be use to coat the drug in order to control the release
  - organic compounds that characteristically consist of a long alkyl chains
  - simple lipids composed of a fatty acid esterified with a long-chain alcohol
  - special molecules with fatty acid chains attached to alcohols
  - synthesized by many plants and animals
  - used as finishes and coatings for wood products
  - water-repellent and are used to coat surfaces
* coat the structures of living materials.
* comes from countries
  - eastern countries
* confer matting effects and wear resistance to paints.
* consists of carbon.
* defines heat index as the combination of temperature and humidity.
* esters in two species of freshwater zooplankton.
* generally accumulate much less gunk than oil-based lubes.
* give an antique, traditional finish to leather.
* has ability.
* includes atoms.
* interfere with the adhesion of new varnish.
* is an organic compound
* occur as protective coatings.
* provide vital waterproofing for body surfaces.
* requires applications.
* seals dust.

Cold wax
* involves wax bonded to strips of paper and is best for smaller, downier areas.
* is harder to scrape.
* work similarly to hot waxes.

### lipid | wax:

Ear wax
* Most ear wax has ability.
* accounts for most ear discharges.
* can plug the opening for sound in the ear mold.
* causes temporary deafness.
* comes from a combination of oil and sweat.
* contains waxy oils but much of it is made up of keratinocytes - dead skin cells.
* has a protective role
* helps keep the ear canal moist and clean, but for some it becomes thick and hard.
* is formed by small glands under the skin of the outer part of the ear canal
  - produced by special glands in the skin in the outer part of the ear canal
* mixture of alcohols and fats secreted by glands in the ear.
* natural product made by the skin of our ear canals for protection.
* protects the ears from excessive moisture.
* serves as a protective lining for the ear canal.

Hot wax
* can cause severe burns, so take great care to avoid contact with the skin.
* is applied to fabric in a design
  - highly flammable and can burn skin - so be extremely careful
* lasts a lot longer than rub-on wax.

Natural wax
* Some natural wax contains hydrocarbons.
* are typically esters of fatty acids and long chain alcohols.

Petroleum wax
* are derived from crude oil.
* reduce tack of letterpress inks, slip agents.

Ski wax
* compound that is often made from a combination of synthetics and natural substances.
* is considerably harder than shoe polish and it gives a high glossy shine
  - used in skiing and snowboarding

Soy wax
* burns cleaner and longer than paraffin wax and produces less soot.
* is added to minimize smoking
  - also clean-burning and produces less soot
  - water soluble , making it easy to extract from glass, tin, fabric, and other materials
