  2. 4. abbreviated O/W emulsion; oil droplets emulsified in water
  3. 11. alcohols that evaporate easily
  4. 14. a substance that causes an increase in cellular mutations, some of which are harmful but others which have little or no effect on the body’s function; may cause cancer but not always
  5. 15. chemical reaction that requires the absorption of energy or heat from an external source for the reaction to occur
  6. 19. the smallest chemical components (often called particles) of an element
  7. 23. required by law for all products sold include safety information about products compiled by the manufacturer, including hazardous ingredients, safe use and handling procedures, proper disposal guidelines, and precautions to reduce the risk of accidental harm or overexposure
  8. 24. a stable, uniform mixture of two or more substances
  9. 25. a measure of the acidity and alkalinity of a substance
  10. 32. also known as bases; compounds that react with acids to form salts
  11. 33. an ingredient that brings two normally incompatible materials together and binds them into a uniform and fairly stable mixture
  12. 37. an ion with a negative electrical charge
  13. 39. a colorless liquid or white crystals with a strong unpleasant odor that is used in permanent waving solutions

  20. 49. chemical reaction that releases a significant amount of heat
  21. 51. sweet, colorless, oily substance used as a solvent and as a moisturizer in skin and body creams
  22. 54. abbreviated VOCs; compounds that contain carbon (organic) and evaporate very easily (volatile)
  23. 55. liquids that are mutually soluble, meaning that they can be mixed together to form stable solutions
  24. 56. subatomic particles with no charge
  25. 57. a substance that causes or is believed to cause cancer
Down
  1. 1. also known as redox; a chemical reaction in which the oxidizing agent is reduced (by losing oxygen) and the reducing agent is oxidized (by gaining oxygen)
  2. 2. a solution that has a pH below 7
  3. 5. rapid oxidation of a substance accompanied by the production of heat and light
  4. 6. a contraction of surface active agents; substances that allow oil and water to mix, or emulsify
  5. 7. an alpha hydroxy acid used in exfoliation and to lower the pH of products
  6. 8. molecule containing two or more atoms of the same element in definite (fixed) proportions
