Question 1: Reducing agent

Answer:

A substance that adds hydrogen to a chemical compound or subtracts oxygen from the compound.

Question 2: Solution

Answer:

a stable physical mixture of two or more substances

Question 3: Alpha Hydroxyl Acids

Answer:

Abbreviated AHAs; acids derived from plants (mostly fruit) that are often used to exfoliate the skin.

Question 4: Oxidation-reduction

Answer:

Also known as redox (ree-DOCS); a chemical reaction in which the oxidizing agent is reduced (by losing oxygen) and the reducing agent is oxidized (by gaining oxygen).

Question 5: Suspension

Answer:

unstable physical mixtures of undissolved particles in a liwuid

Question 6: Exothermic reaction

Answer:

Chemical reactions that release a significant amount of heat.

Question 7: Ammonia

Answer:

Colorless gas with a pungent odor that is composed of hydrogen and nitrogen.

Question 8: Volatile Organic Compounds

Answer:

Abbreviated VOCs; compounds that contain carbon (organic) and evaporate very easily (volatile).

Question 9: Immiscible

Answer:

liquids that are not capable of being mixed together to form stable solutions

Question 10: Thioglycolic Acid

Answer:

A colorless liquid or white crystals with a strong unpleasant odor that is used in permanent waving solutions

Question 11: Glycolic Acid

Answer:

An alpha hydroxy acid used in exfoliation and to lower the pH of products.

Question 12: Glycerin

Answer:

Sweet, colorless, oily substance used as a solvent and as a moisturizer in skin and body creams.

Question 13: Solvent

Answer:

the substance that dissolves the solute and makes a solution

Question 14: Emulsifier

Answer:

An ingredient that brings two normally incompatible materials together and binds them into a uniform and fairly stable blend.

Question 15: Miscible

Answer:

liquids that are mutually soluble, meaning that they can be mixed together to form stable solution

Question 16: Water-in-oil emulsion

Answer:

Abbreviated W/O emulsion; water droplets emulsified in oil.

Question 17: Surfactant

Answer:

A contraction of surface active agents; substances that allow oil and water to mix, or emulsify.

Question 18: Emulsion

Answer:

An unstable physical mixture of two or more immiscible substances (substances that normally will not stay blended) plus a special ingredient called an emulsifier.

Question 19: Combustion

Answer:

Rapid oxidation of a substance accompanied by the production of heat and light.

Question 20: Silicone Oils

Answer:

Special type of oil used in hair conditioners, water-resistant lubricants for the skin, and nail polish dryers.

Question 21: Solute

Answer:

the substance that is dissolved in a solution

Question 22: Oil-in-water emulsion

Answer:

Abbreviated O/W emulsion; oil droplets emulsified in water.

Question 23: Volatile alcohols

Answer:

Alcohols that evaporate easily.

Question 24: Alkanolamines

Answer:

Alkaline substances used to neutralize acids or raise the pH of many hair products.

Question 25: Oxidizing agent

Answer:

Also known as redox (ree-DOCS); a chemical reaction in which the oxidizing agent is reduced (by losing oxygen) and the reducing agent is oxidized (by gaining oxygen).
