This section provides a physical profile of the chemical
through its various characteristics. Information given here applies to
the product as a whole (In this case, Bowl Descaler Pro.), not just to
specific ingredients. Items which may be listed here are:
Looking at our sample MSDS, we see that the vapor pressure
for Bowl Descaler Pro is N/D, or not determined. Its vapor density is >1,
meaning vapors will tend to sink. Its pH is <1, or highly acidic. Specific
gravity is 1.12, or greater than water, so it will tend to sink in water.
97% of the product can evaporate. Its evaporation rate is the same as water.
The product is completely soluble in water.
boiling point (BP)
melting point (Only applies to solid materials.)
vapor pressure (Substances with VPs above 20 mm Hg
may present a hazard due to their volatility.)
vapor density (VD) VD of air=1. Materials with a VD
less than 1.0 are lighter than air and their vapors will rise. Materials
with a VD greater than 1.0 are heavier than air, and their vapors will
sink to the floor or the lowest point available.
specific gravity (SG) Water=1. Materials with an SG
less than 1.0 will float in water. Materials with an SG greater than 1.0
evaporation rate (The rate at which a product will
vaporize when compared to the rate of a known material. ServiceMaster compares
its products to water. On a ServiceMaster MSDS an evaporation rate of 1
means a rate the same as water. Greater than 1 is faster than water, and
less than 1 is slower than water. Other MSDSs might use butyl acetate for
comparison. Normally, an MSDS will tell you what other material is the
basis for comparison. This ServiceMaster MSDS is flawed because it does
solubility in water (How much by weight will dissolve
solubility in other solvents
volatiles by volume (Percent that will evaporate.)
appearance and odor (Comparing this description to
the actual product is one way to be sure you have the correct MSDS.)
