Chemistry & Chemical Safety

A substance that causes or believed to cause cancer

SDS category of "Stability & Reactivity" provides what

Stable, uniform mixture of two or more substances

An atom or molecule that carries an electrical charge

Used to neutralize acids or raise the pH of many hair products. Often used in place of ammonia

Any substance that occupies space and has mass (weight)

A pH AT 7 is what kind of solution

Change in composition or makeup of a substance usually by combining or subtracting certain elements

Represents quantity of hydrogen ions & it's scale is used to measure acidity & alkalinity of substances

Change in form of a substance without the creation of a new substance

Chemical reactions that requires the absorption of energy or heat from external source for reaction to actually occur

Substance that MAY cause cancer but not always

Separation of an atom or molecule into positive and negative ions

______ molecules are chemical combinations of two or more Atoms of different t elements in definite proportions

What is NOT true about mixing chemicals

These evaporate easily and come in many types of free-flowing liquids to hard waxy solids

Elements produced artificially through synthesis are called what

Ion with a positive electrical charge

Refers to how a substance is used and how much of it is used and is determined by overexposure

Not capable of being mixed together to form stable solutions

How long can properly formulated Emulsion be stored under ideal conditions & what time frame is recommended to use them

Liquid that is capable of igniting but has a Flashpoint between 100-200 degrees Fahrenheit

Combination of matter in any proportion where the substance has the combined properties of the substance in the mixture

Subatomic particles with NO charge

A pH ABOVE 7 indicates

Tail of a surfactant molecule

Whats NOT true of the Safety Data Sheet (SDS)

Contain carbon & evaporate easily . Used in hairspray, nail polish, base and top coats, and polish removers

Substances that allow oil and water to mix, or emulsify

Liquid easy to ignite and has a Flashpoint below 100 degrees Fahrenheit.

What is NOT true about safely transporting chemicals

The head of surfactant molecule

A molecule containing two or more Atoms of the same element in definite proportions

Subatomic particles with a positive charge

All matter is made up of what

Science that deals w/ composition, structures & properties of matter and how matter changes under different conditions ​

Chemical combination of matter in definite proportions

Which is NOT true about oil-in-water (O/W) Emulsion

Occurs when acid is mixed with an alkali in equal proportions, balancing the total pH and forming water (H2O) & salt

Type of oil used in hair conditioner,Water-resistant Lubricants & nail polish dryers. Less greasy & form breathable film

What is NOT a reason beauty professionals should have a thorough understanding of chemistry

Are mutually soluble, meaning that they can be mixed together to form solutions

Substance that is dissolved in a solution

Simplest form of chemical matter and contains only one type of atom

Sweet, colorless, oily substance used as a solvent and as a moisturizer

Ability to rust, burn or change color are examples of which type of properties

Substance that dissolves the solute and makes the solution

Molecules are made by

Basic unit of matter with a nucleus center surrounded by negatively charged elections that move around nucleus in orbits

Unstable physical mixtures of two or more immiscible substances plus a special ingredient called an emulsifier

Examples of this type of properties are color, solubility, odor, density, melting point, boiling point, hardness, gloss

Unstable physical mixtures of undissolved particles in a liquid

Prolonged, repeated, or long-term ​exposure to certain product ingredients can cause sensitivity in some people

When certain chemical reactions release energy in the form of heat

Colorless gas composed hydrogen and nitrogen that has a pungent odor . It is used to raise the PH in hair products

A pH below 7 indicates this type of solution
