Chemical Structure
Made up of elements that have their own distinct physical and chemical properties.
Matter
A chemical combination of matter in fixed proportions.
Pure substance
Known as the universal solvent.
Water

What is average pH of skin and hair.
5
Results from loss of hydrogen.
Oxidation
Chemical combination of two or more atoms in fixed proportions.
Molecules
All matter can be classified as either a __________ or a __________.
Pure Substance
Physical Mixture
Which type of emulsion feels more greasy? O/W or W/O
Water in oil
The more hydroxide ions there are in a substance the more _________ it will be.
Alkaline
Requires the absorption of energy or heat from an external source for the reaction to occur.
Endothermic Reaction
Basuc unit of matter. Contains nucleus that consist of protons which determine the element.
Atom
These neutralize acids or raise the pH of many hair products. Often used in place if ammonia.
Alkanolamines
Used as both a solvent and a moisturizer in skin and body creams.
Glycerin
How many more times is a pH of 5 more acidic than a pH of 3.
100 times
When acid is mixed with an alkali in equal proportions, balancing the total pH.
Acid-alkali neutralization reaction
Represents the number of protons for an element.
Atomic Number
Less greasy than oils. Used in water-resistant lubricants for the skin.
Silicones
Compounds that react with acids to form salts.
Alkalis
What would be result of applying acidic products to dry, dehydrated skin?
It would further dry and irritate skin.
When oxidation and reduction take place at the same time.
Redox (Oxidation-reduction)
