Experiment of Lipstick Formulation
Introduction
Cosmetics
can be traced to ancient civilizations.In particular,the use of lip color was
prevalent among the
Sumerians,Egyptians,Syrians,Babylonians,Persians, and Greeks.Later,Elizabeth I
and the ladies of her court colored their lips red mercuric sulphide.In Western
society during the later half of the nineteenth century,it was generally
believed only promiscuous women wore lipstick.Then,lipsticks are made to appeal
to the current fashion trend and come in a wide range of colors.Lipstick is
made of dyes and pigments in a fragranced oil-wax base.The primary ingredients
found in lipstick are wax,oil,alcohol and pigment.Lipstick, is also a symbol of
feminine beauty and sensually and a method of attracting attention.The red
color of the lips was first accentuated in the ancient world.Today, a woman
uses lipstick to highlight her individually,character and seductive capacity to
underline her smile.
Objectives
-Differentiate the different function of
each ingredient in the formula
-Understand the rational and function of
the different type of formulation of the lipstick
-Evaluate the quality of lipstick

Discussion
For
this formulation, we have decided to not do any changes on phase B and C. This
is because any unsuitable alteration to them may lead to hardness or the
lipstick becomes too soft. Therefore, we use different types of pigment with
different mass without changing the volume of castor oil. The first formulation
used 2 types of pigment which are red with 1.5 g and 0.5 g blue. By mixing
them, we got purple color of lipstick. For the second formulation, we used only
one purple pigment at 0.5 g. Third formulation involve 0.5 g of red pigment.
Forth formulation included 0.5 g of blue and 1.0 g of red pigment. Next we mix
silver and red pigments of 0.6 g and 0.5 g respectively. For the last
formulation, we mix 0.1 g of gold with 15 drops of carmoisine.
An
evaluation is done for these product. All of them was evaluated at the room
temperature. For formulation 2, it is not hard and a bit melt compared to the
others. The others does not show any changes. Formulation 2,3 and 5 was placed
without the existence of light while formulation 1,4 and 6 is without light .
However at the end of the day, we consider all the formulation is passed.
CONCLUSION :
Different
pigment give different colour to the lipstick. Combination of two pigments will
give another colour to the lipstick but the colour and its’ intensity may also
depends on the mass of the pigment used. Phase B and C is the same as we do not
want to disturb or change the hardness of the lipstick. After evaluation is
done, all the formulation is passed.

Experiment of Deodorant and anti-perspirants
TITLE : Deodorents and anti-perspirants
INTRODUCTION :
Deodorents and anti-perspirants are preparations that can mask,
remove or reduce the unpleasant odor on the body due to sweat. Sweat on its own
does not generally have a smell; bacteria present on the surface of the skin
digests the sweat and the digestion and breakdown products cause the odor. Therefore, a deodorant
functions by decreasing the bacteria population on the skin or by adding
fragrance to the body to overcome the foul odor. On the other hands, the
anti-perspirant functions by reducing the production of sweat through its
astringent property.
OBJECTIVE:
1. To
prepare the products based on different fragrances
2. To
evaluate the effectiveness of the products.
3. To
test the stability of the products.
MATERIAL: Beeswax, coconut oil, silicone oil, cocoa butter, vitamin E oil, corn
starch, essential oil/perfumes.
PROCEDURE:
1.
The beeswax and cocoa butter were
heated until they are just melted. Then, coconut, silicone and vitamin E oil
were added.
2.
When all the oils and fats have
melted, the essential oils and perfumes were added.
3.
The corn starch was mixed in using
hand mixer until homogenous.
4.
The molten mixture was pour into
the container and was allowed to cool until it hardens.
Evaluation of products
1.
Each member of our group was taken
her turn to test the products.
2.
A simple questionnaire was devise
that will allow each person to compare the effectiveness of each product and
whether the fragrance incorporated is irritating to the skin.
3.
In the morning, a shower was taken for the
test and was dried by a towel. The underarm that will function as the control
was determined. Any preparation was not applied on this underarm. The same
underarm was used as the control throughout the study.
4.
On the other underarm, not more
than 1g of our product was applied.
5.
After exactly 9 hours of normal
daily activities, the questionnaire was filled.
Stability testing
1.
All the remaining product were
placed in one warm and sunny position.
After 4 weeks, the product was evaluated
Discussion
Antiperspirants
are usually deodorants impede the production of perspiration.Most
antiperspirants contain active ingredient such as aluminium chlorohydrates or
aluminium zirconium tetrachlorohydex glycine complex.Aluminium salts function
as astringents,producing an insoluble hydroxide gel in the sweat pores and thus
physically blocking the release of secretory products by constricting the
opening of the sweat gland ducts.The active ingredient in antiperspirants may also reduce odor,most
likely by destroying bacteria.Deodorants and antiperspirants can be formulated
into creams or lotions typically containing an oil base,solvents,propylene
glycol,emollients,lubricants,humectants and preservatives.Deodorants and
antiperspirants can also be dissolved in a solvent and applied as an aerosol
with the use of nonchlorofluorocarabon propellant.
Conclusion
To introduce new antiperspirant actives requiring costly studies on safety and
effectiveness.Aside that the
introduction of new antiperspirant, should be continually monitored the
introduction of unregulated ingredients that would be included in existing or
new formula.
