Safety and Disinfection
cleaning tools with warm, soapy water and submerging in a EPA disinfectant
What is disinfecting?
protein building blocks of hair that link together and form tiny fibers
What are amino acids?
polypeptide chains side-by-side and are responsible for the hair's strength and elasticity
What is a side bond?
matter
What is a substance that has mass and occupies space?
a mixture that blends 2 or more small particles of gases, liquids, and solids that DO NOT separate
What is a solution?
sets the standard for what information the SDS contains
What is GHS?
very strong and create a spiral chain effect
What are peptide bonds?
weak bond broken by water or heat; reformed by drying or cooling the hair
what is a hydrogen bond?
smallest part of an element
What is an atom?
A substance that is able to be mixed with another substance.
Ex: alcohol and water
what is miscible?
mandates that every chemical located within a business has a SDS available
What is OSHA?
What are polypeptide chains?
weak bond broken by changes in potential hydrogen; reformed by balanced potential hydrogen
What is a salt bond?
when one or two atoms combined and retain their chemical and physical properties to form matter
What is a molecule?
Consists of two or more types of matter blended together, but not chemically altered
What is a physical mixture?
cleaning tools with warm soapy water water to remove all debris and placing them in a high pressure steam unit
What is Sterilization?
cortical fibers grouped together produce
what is a cortex?
strong bond broken by chemical solutions; restored by neutralizing solutions
what is a disulfide bond?
also known as chemical compounds, chemical substances consisting of atoms or ions of 2 or more elements in definite proportions, which cannot be separated by physical means
What are compounds?
Describe the process of temporary change
*Answers may vary, teacher will decide on points
strand tests are to be performed before every chemical service to determine processing time
What are preliminary strand tests?
The dried, dead cells that surround the cortex
What are cuticle scales?
The structure of hair
cuticle, cortex, and medulla
properties and changes of matter
What is physical change, physical properties, chemical change, and chemical properties?
Describe the process of permanent change
*Answers may vary, teacher will decide on points
