Study Notes
Chemistry Basics
- Chemistry is the science that deals with the composition, structure, and properties of matter
- Atoms are the basic building blocks of all matter and are the smallest particle of an element that has the chemical identity of the element
Chemical Compounds and Properties
- Chemical compounds are combinations of two or more atoms of different elements united chemically with fixed chemical composition, definite proportions, and distinct properties
- Compound molecules are two or more atoms of different elements united chemically with fixed chemical composition, definite proportions, and distinct properties
- Chemical properties are characteristics that can only be determined with a chemical reaction
- Chemical change is a change in the chemical composition of a substance by which new substances are formed
pH and Solutions
- Acids are solutions that have a pH below 7.0
- Alkalis (also known as bases) are solutions that have a pH above 7.0
Shampoos
- Balancing shampoos are designed for oily hair and scalps, washing away excess oiliness while keeping the hair from drying out
- Clarifying shampoos contain an active chelating agent that binds to and helps remove metals from the hair, providing thorough cleansing and cutting through product buildup
- Color-enhancing shampoos are created by combining surfactant bases with basic dyes
