INVESTIGATORY PROJECT PRESENTATION
GROUPS 5 and 11

INTRODUCTION:
BACKGROUND OF THE STUDY:

Candle is an important material and is sometimes used in our community. In our modern times, it is used mainly for its aesthetic purposes and scent. Its fragrant smell is known for This study will be conducted in order to know the capabilities of the candle with used cooking oil and learn the difference of it from the commercially produced candles. This study aims to develop a better product that the commercial candles. By doing this, we could refrain from throwing cooking oil after being used, and make use of it as an additive material in making candles. The researchers wanted to develop a cheaper and recycled candle that can be easily made at home and with materials that are eco-friendly, recycled and can be commonly seen. It is easy to make a candle and is a good hobby. By doing this, we can save money and save mother earth.aromatherapy. Candles are also essential especially during power failures and emergencies

SIGNIFICANCE OF THE STUDY:
The study is significant to the following:
Environment
This study will help in the conservation of water forms. This study will also produce candle which
can be substituted to the commercially produced candles. With this, there will be less pollution
coming from factories.
Economy
This study will help our economy if this research will be patented and exported to other countries.
It can also be a source of livelihood to other people.
Household
This study will help the citizen in saving money, for they don’t need to spend money buying
candles. Instead, they could do it on their self.





As early as the biblical times, the presence of candles is already mentioned. First candle
were made of flax thread coated with wax and pitch. Palm oil, bee wax, coconut oil, and olive oil
are also used to produce these candles during the olden times. But as time passes by, there were
changes that took place in candles. Not only on its appearance, but also in the materials being
used to produce one. Up to the present, candles are still being used by every household and can
be consider as a necessity.
Knowing that candle is a necessity for every household, the researchers come to make a way to produce a candle which is cheap at the same time could help the environment. Given the
information that palm oil, coconut oil, and olive oil were used in the production of candle during
the olden time. The researchers come to test if cooking oil can also produce a candle which is as
effective as normal candle. Cooking oil are usually thrown every after use, and it contributes to
the pollution if our environment.
The researchers not only aim to produce a candle out of cooking oil, but also produce a
product which has same quality and as efficient as commercially produced candle. Not only will
it the environment, but also the people who will be able to save money.


HYPOTHESIS:
STATEMENT OF THE PROBLEM:
-The candles made of used cooking oil will not be as effective as the commercially produced candles.
-The candle which is made by vegetable oil used on pork will be more favorable to the public than of the ones used by fish and chicken
-None of the 3 candles made of used cooking oil will be accurate enough in terms of color, texture, odor and span.

METHODOLOGY:

Materials:
• 500 mL used cooking oil
• 1 kg paraffin wax
• strings cut into 5 inches long, serves as wick
• crayons in different colors
• kettle
• beaker
• stirring rod
container(aluminum/glass)
Procedure:
The measured paraffin waxes will be cut into small pieces to facilitate melting. It will be placed in a clean and dry kettle, together with a small piece of colored crayon, to produce a colored candle. The kettle will be heated in low fire until the waxes and crayons melt. The melted wax will be added with different percentages of used cooking oil. Before the mixture solidifies, they will be formed into molds, wicks suspended in the middle of the container. They will be air-dried until hardened.
DEFINITION OF TERMS:
Flax- a plant that has blue flowers and that is grown for its fiber and its seed
Paraffin - a soft, waxy substance that is usually made from petroleum or coal and is used in
candles and other products
Petrochemicals- a chemical isolated or derived from petroleum or natural gas
Polyurethane- a type of plastic that is used to make various products and especially to make a clear
liquid that is spread on a surface (such as a wooden floor) and that becomes hard when it dries
Wick- a string or piece of material in a candle or lamp that is lit for burning

REVIEW OF RELATED LITERATURE
Candles used to be largely made up of solid combustible waxes of fatty substance formed around a wick. It is a source of light. Beeswax candles were used in Egypt and Crete as early as 3000 B.C.
Much later, candles were made by pouring molten wax or tallow into molds, containing wicks. Next
came the paraffin wax, which is crystallized from petroleum. Today, commercially available candles
are approximately made up of 65 percent paraffin wax and 35 percent stearic acid.
Waxes compromises a broad group of opaque, water repellent, essentially solid materials having
varied chemical composition and many diverse applications. Its name applied originally to naturally
occurring esters of fatty acids and monohydric alcohols but not refers to both natural and
manufactured products resembling these esters. They soften gradually on heating, going through a
soft, malleable state before ultimately forming a liquid.
Oils are greasy, generally combustible liquid of vegetables, animals or mineral origin which is
insoluble in alcohol and always in Ether. Oils are used as food, for lubricating, illuminating and as
fuel. It is also used in the manufacture of soap, candles, cosmetics, perfumery, etc.
Wick were made up of cotton or linen woven and braided in such a way that it will burn i n one
direction, curling so as to texture its end into oxidizing zone of the candles flame for complete
combustion.

1. What are the diff. characteristics of sample candles in terms of color, odor, texture and span?
2.which of the 3 candles made of used cooking oil is accurate enough in terms of color, odor, texture and span?
3. will the 3 candles be as effective as the commercially produced oil?
