Glossary of Industry Terms

The purpose of this glossary was originally to assist those who have English language difficulties to better understand some common terms used in the US that may not have clear translations into other languages. The glossary has since been expanded and can also serve as a study aid for candidates preparing for the CPCP examinations who wish to review terminology.

 

Acute:   The rapid-onset, short-term initial stage of disease. Contrast with chronic.

 

AIDS:  Acquired Immunodeficiency Syndrome

 

Alcohols:  A group of organic compounds derived from the alkanes by the substitution of one hydroxyl radical for one hydrogen atom. In some benign forms, they are glycols used as humectants that help deliver ingredients into the skin as in skin moisturizers. There are many: ethanol, denatured alcohol, ethyl alcohol, methanol, benzyl alcohol, isopropyl alcohol, and SD alcohol. These alcohols are frequently used in tattoo pigments.

 

Analgesic:  1. Relieving pain. 2. A drug that relieves pain.

 

Antibacterial:  Destroying or inhibiting the growth of bacteria.

 

Antibiotic:  Any variety of natural or synthetic substances that inhibit growth of or destroy microorganisms. Used extensively in treatment of (and prophylactic prevention of) infectious diseases.

 

Antimicrobial:  Destructive to or preventing the development of microorganisms. Also refers to an agent that destroys or prevents the development of microorganisms.

 

Antiseptic:  A mild disinfectant used on the skin and mucous membranes to lower the count and inhibit the growth of bacteria; an agent capable of producing antisepsis by preventing or prohibiting the growth of causative microorganisms.

Autoimmune Disorders:  Disorders or diseases in which the body produces a disordered immunological response against itself. Normally the body’s immune mechanisms are able to distinguish clearly between what is a normal substance and what is foreign. In autoimmune diseases this system becomes defective and produces antibodies against normal parts of the body to such an extent as to cause tissue or organ injury.

Carbon Black:  Carbon Black, Pigment Black 6 and 7 – color index # 77226 is the generic name given to the product resulting from the partial oxidation or thermal decomposition of liquid or gaseous hydrocarbons. Variation in the process control conditions and the combustible hydrocarbons will result in the production of a wide variety of carbon blacks. Such differences yield carbon blacks described as lamp black, bone black, channel black, acetylene black, thermal black, and furnace black. Thermal and furnace are the carbon blacks mostly used in permanent cosmetics.
