Study Notes

Chemistry Fundamentals

  • Organic chemistry involves substances containing carbon.
  • Hair color products are classified as organic chemicals, thus containing carbon and hydrogen.

Types of Chemistry

  • Inorganic chemistry studies substances that lack carbon but may contain hydrogen.
  • Inorganic substances are characterized by the absence of carbon.

Matter and Its Composition

  • An element is the simplest form of chemical matter and cannot be broken down without losing its identity.
  • There are 98 naturally occurring elements, each with unique physical and chemical properties.
  • An atom is the basic unit of matter, consisting of a nucleus surrounded by negatively charged electrons.

Chemical Combinations

  • A molecule forms when two or more atoms chemically combine.
  • A compound results from the chemical combination of atoms from different elements, with sodium chloride being a common example of a compound molecule.

States and Properties of Matter

  • Liquids have a definite volume but take the shape of their containers.
  • A neutral solution has a pH value of seven.

Ions and Ionization

  • Cations are ions with a positive charge.
  • Ionization refers to the process of separating an atom or molecule into positive and negative ions.
  • Ions are charged atoms or molecules.

Hydrophilic and Lipophilic

  • Hydrophilic describes substances that attract water.
  • Lipophilic refers to substances that attract fats and oils.

Solutions and Mixtures

  • Cold cream exemplifies an oil-in-water emulsion.
  • Alkanolamines are substances used to neutralize acids and raise pH in hair products.
  • Ammonium hydroxide is an ammonia compound commonly used in salons.

Moisturizing Agents

  • Glycerin is a colorless, sweet oily substance used as a moisturizer in skin and body creams.
  • Ethyl alcohol is a volatile organic compound frequently used in hair spray.

Chemical Properties and Changes

  • The ability of a substance to rust is a chemical property.
  • Physical changes do not cause a chemical reaction, while chemical changes involve transformations like hair color oxidation.

Chemical Reactions

  • Redox reactions occur when the oxidizing agent is reduced and the reducing agent is oxidized.
  • Exothermic reactions release heat.
  • Combustion is the rapid oxidation of a substance producing heat and light.

Pure Substances and Mixtures

  • A pure substance consists of matter in fixed proportions.
  • Air is an example of a physical mixture, containing nitrogen, carbon dioxide, and water vapor.

Solutions and Solvents

  • A stable physical mixture of substances in a solvent is referred to as a solution.
  • A solvent dissolves another substance to form a solution.

Miscibility and Emulsions

  • Miscible liquids can mix to form clear solutions, with water and alcohol being examples.
  • An emulsion is an unstable physical mixture of two or more immiscible substances.
  • Surfactants are substances that enable oil and water to mix or emulsify.
