Transcripts
it is
Hawaiian and good day future chemist
welcome to the general chemistry one
class this section is a matter and its
properties focusing on chemicals in
consumer products
let's begin
in this lesson we will compare consumer
products on the basis of their
components for use safety quality and
costs
[Music]
anything around us is made up of
chemicals in contrast to a negative
connotation that chemicals are just
substance that are bugs or health
chemicals are present even in Goods
essential to our daily lives
for this lesson we will discuss some of
the chemicals found in consumer products
like toothpaste food products and salt
and detergents
yeah
first are toothpaste
fluoride is one of the active
ingredients of toothpaste
most fluoride containing compounds used
are sodium fluoride and sodium
monofluorophosphate
fluoride helps in strengthening the
animal the outermost layer of our teeth
sodium fire phosphate this also added to
minimize accumulation of third part
kills bacteria in mouth and is used in
toothpaste formulation to prevent
gingivitis or inflammation of gum pieces
surfactants like sodium Laurel sulfate
or SLS
unresponsible for bubbling of toothpaste
during brushing such chemicals are
important for Effective removal of flake
which barely mixed with water however
some people experience irritation to SOS
well this SOS free token are available
in the market these products use other
surfactants matter that SLS
[Music]
compounds such as glycerol
prophylene glycol and sorbital
serves Health in preventing toothpaste
from dining once it is exposed to air
[Music]
don't like season fun gum or Salinas gum
or added to thicken the formulation
these chemicals are big molecules called
polysaccharides
[Applause]
of recent Asians like hydrated silica
aluminum oxide and magnesium carbonates
made in removing animal stains keeping
teeth white
[Music]
phone grains like peppermint which
contains methanol and method
experiment contain carbon and cloth
containing eugenol or added in small
amounts to give pearlescent flavors
nuts are food products food products are
important for our survival however in
selecting food products it is important
to consider chemical processed as these
chemicals can provide us nutrients will
something cause adverse effects or help
upon consumption
the second food products one of the most
important things you need to chat on the
label are the nutrition facts nutrition
facts so the recommended serving of a
food product as well as its nutrient
content expressed in amount and percent
daily volume
survey is the amount of food products
that gives the amount of nutrients in
the nutrition facts calorie is the
amount of energy that one can get upon
the food intake
good labels usually reflect the number
of calories per serving people who want
to maintain or reduce the weight
check for products that are relatively
low in calories
it's the relative amount of nutrient
present in one serving we're just packed
to the prescribed daily measurement
requirements
[Music]
the daily value of the nutrient is based
on the nutrient content from a 2 000
calorie daily diet the value of five
percent and below is considered low
dietitians recommended food product with
low percent of DV for saturated fat
trans fat cholesterol and sodium is
desirable as too much consumption of
these nutrients are associated with
heart disease and high blood pressure
on the other hand values of 20 and
higher are considered high which is
desirable for vitamins minerals and
fibers
other than times are also indicated here
such as proteins and sugars protein is
essentially for the development of our
body sugars are sources of additional
energy but intake should be in
moderation as too much sugar can cause
obesity
aside from nutrition fact it is also
important to look at the ingredient
listed her in are the main ingredients
including some substance added to
improve the quality of the product
food additives
are a sub stance added and improve the
taste
taste quality of food
food preservatives are added to prolong
the shelf life of food by slowing down
the growth of microorganisms
nitrites and nitrates are example of
these preservatives used in meat
production
nitrites and nitrates are reported as
potential source of cancer causing
substance with these some consumers but
denies the nitrate and deny correct free
products
manufacturers claim that they do not use
synthetic nitrate or not try itself but
use alternative like
ciliary which still contain nitrate and
nitrate but the naturally occurring ones
foreign
mixed with some products to add or
improve nutrient content this process is
called fortification in the Philippines
locally made products pair with a Sanka
Pinoy seal on the label to indicate that
these products have undergone
fortification and past certain standards
color editors are included to make the
food products more appealing in color
different plants can be used as natural
color adjectives they contain chemical
responsible for the distinct colors
example or a matter
blueberry and turmeric
there are chemicals prepared and used as
artificial coloring agent however
addition of these chemicals must be done
in small amount as they can cause health
problems some of the most common
artificial food colors are the FD and C
food colors
sometimes
manufacturers emphasize some substance
that might be present also not listed as
ingredients but may have contained the
product during its process this is
important to alert consumers who might
have allergies to these substances
well let us proceed the Soaps and
detergents soaps our substance made by
mixing oil and an alkaline substance
such as lime
sodium hydroxide or caustic potage or
potassium hydroxide
solid soap is produced when lye is used
while liquid soap can be made using
potash
[Music]
foreign
bacterial soaps contain triclosan and
dry
glucarbine however the U.S Food and Drug
Administration reports that there is no
study proving that the presence of
tricloside and triclucarban
significantly remove bacteria in
comparison to soap products without
these chemicals
detergents on the other hand are usually
sulfate salts
these are normally used as cleaning
materials in household cleaning and in
washing clothes and dishes aside from
the sulfate salt in detergents and other
ingredients may be useful to our body
his detergents are not advisable to be
used in day thing
[Music]
consumer products in general may vary
from one to another in price
runs that are more expensive are not
always of better quality than the
cheaper ones
when choosing between Brands consider
not only the cost and quantity as most
of us do
shaking its chemical composition is a
must in order to find out which the best
serves
its purpose without putting our health
into compromise that just be deceived by
its cost
foreign
composition is very important
consideration in choosing consumer
products one must get to know which
ingredients are good and dangerous to
help
here are references and bibliography
thank you for watching and God bless
[Music]
