Uniform mixture of two or more substances
Solution
Combination of two or more substances that are united physically, in any proportions with combined properties
Physical mixture
These have neither a definite size nor a definite shape
Gases
Unstable mixture of two or more immiscible substances
Suspension
Chemical reaction in which the oxidizing agent is reduced and the reducing agent is oxidized
Redox reaction
Droplets of water dispersed in an oil
Water-in-oil emulsion
These have a definite size but not a definite shape
Liquids
Substances with a pH below 7.0
Acids
These are used to emulsify oil and water
Surfactants
Characteristics that can be determined only with a chemical reaction and that cause a chemical change in the identity of the substance
Chemical properties
Droplets of oil dispersed in water with the aid of an emulsifying agent
Oil-in-water emulsion
Characteristics that can be determined without a chemical reaction and that do not cause a chemical change in the identity of the substance
Physical properties
Rapid oxidation of a substance, accompanied by the production of heat and light
Combustion
These have a definite size and a definite shape
Solids
Also known as bases; have a pH above 7.0
Alkalis
Rapid and interrupted current, flowing first in one direction and then in the opposite direction
Alternating current (AC)
Flow of electricity along a conductor in a complete circuit
Electric current
Process of infusing a negative (alkaline) product into the skin
Anaphoresis
Positive electrode
Anode
This supplies current to the circuit
Live connection
Application of light rays to the skin for the treatment of acne, wrinkles, capillaries, pigmentation, or hair removal
Light therapy
Any material that easily conducts electricity
Conductor
This indicates the negative or positive pole of an electric current
Polarity
This completes the circuit and carries the current safely away to the ground
Ground connection
Constant, even-flowing current that travels in one direction only
Direct current (DC)
Extremely low level of electricity that mirrors the body’s own natural electrical impulses

Substance that provides energy to cells and converts oxygen to carbon dioxide
Adenosine triphosphate
Organic acids that form the building blocks of protein
Amino acids
These break down the basic chemical sugars that supply energy for the body
Carbohydrates
Condition in which blood glucose or blood sugar drops too low
Hypoglycemia
Essential trace minerals and vitamins that we need for proper body functions
Micronutrients
Carbohydrate-lipid complexes that are good water binders
