• International Nomenclature of cosmetic Ingredients Dictionary


  The raw materials that are used in most cosmetics around the wworld are listed in this dictionary
• Functional, aesthetic, and claims


  Three types of cosmetic ingredients
• Functional ingredients


  Are the ones that provide benefit of cosmetics

  - Surfactants, conditioning agents, colorants, fragrances, reactive ingredients, film formers, and drug actives.
• Aesthetic ingredients

  - Solvents, thickeners, preservatives, pH adjusters, plasticizers, fillers, appearance modifiers, anti-oxidants, anti-irritants, delivery systems
• Claims ingredients


  It is sometimes called asfairy dust Are ingredients added to formula at a low level for the primary purpose of getting to put the ingredient name of the label- Natural extracts, vitamins, proteins, biotechnology, other fanciful made-up ingredient names

• Absorption


  This is a physical process which involves the assimilation of one body by another
• Adsorption

  Where one substance clings to the surface of another substance, withouth being assimilated by it, or having chemical reaction from it
• Analysis


  This is where a reaction to separate a compound or substance takes place
• Calorie


  It is simply a unit of energy
• Catalysis


  The process of adding a catalyst to a reaction to speed up that reaction
• Catalyst


  Substance that speed up the reaction, it remains intact and cannot be destroyed or changed by the process
• Colloid


  A form of a suspension with some characteristics of a solution
• Conduction


  This is how heat is transferred along with a metal
• Convection


  Method of transferring heat through the air
• Crystallization


  Involves negative and positive ions being packed tightly together, in order to form a crystal lattice in aparticular order to form crystals
• Decantation


  Process of pouring a liquid from one container into another in such way as to leave the sediment behind undistributed
• Dispersion


  A colloidal system consisting of dispersed particles and the medium in which they are suspended
• Distillation


  Involves a process of vaporization followed by condensation.

  The difference in the boiling point of various substances is utilized to separate them
• Distillate


  The condensed material in distillation
• Residue


  The uncondensed material in distillation
• Emulsifier


  Substance that allows two immiscible liquids to come together in order to combine to form a stable suspension
• Emulsion


  This is when a suspension in both phases consists of immiscible liquids
• Enzyme


  A biological catalyst
• Filtration


  Process used to separate two components, as long as one component is an insoluble solid.

  Invovles passing through a filter
• Homogenous


  A mixture that is uniform in composition.

  In one phase
• Heterogenous


  Mixture of non-uniform composition.

  More than one phase
• Hydrogenation


  Term used where a substance combines with hydrogen
