basics
the science that deals with the composition, structures, and properties of matter and how matter changes under different conditions
what is chemistry
Particles from which all matter is composed
what is an atom
a stable, uniform mixture of two or more substances
what is a solution
substances that allow oil and water to mix, or emulsify
what are surfactants
a solution that has a pH below 7
what is acidic
the study of substances that contain carbon, which allows them to burn. All living or formally alive things contain carbon
what is organic chemistry
A result of joined atoms
what are molecules
a substance that is dissolved in a solution
what is solute
water loving
what is hydrophilic
a solution that has a pH above 7
what is alkaline
the study of substances that do not contain carbon, but may contain hydrogen
what is inorganic chemistry
subatomic particles with a negative charge
what are electrons
a substance that dissolves a solute and makes it a solution
what is a solvent
oil loving
what is lipophilic
AHA used in exfoliation and to lower the pH of products
what is glycolic acid
Anything that occupies space, has physical and chemical properties, and exists as either a solid, liquid, or gas
what is matter
subatomic particles with a positive charge
what are protons
liquids that are mixable
what is miscible
an atom or molecule that carries an electrical charge
what is ion
acids derived from plants that are often used to exfoliate the skin
what are AHAs
The simplest form of matter
what is elements
subatomic particles with no charge
what are neutrons
an ingredient that brings two normally incompatible materials together and binds them into a fairly stable mixture
what is emulsifier
an ion with a negative electrical charge
what is anion
the pH of skin
what is 5.5
