The tested plants will reward us the possible colors to be used as an effective alternative dye.

Scope And LimiTaTionS...

This study is limited only in exploring the individual potential of the tested plants is in extracting the expected colors which are to be used as an alternative dye over commercial ones.

defiNiTiOn Of Terms...

Dye - colored substance that has an affinity to the substrate to which it is being applied.

Substrate - the material or substance on which an enzyme acts.

Aqueous solution - is a solution in which the solvent is water.

Pigment - is a material that changes the color of light it reflects as the result of selective color absorption.

Carotenoids - organic pigments that are naturally occuring in chromoplasts of plants and some other photosynthetic organisms like algae, some types of fungi and bacteria.

Chlorophyll - is a green pigment found in most plants

Mordant - is a substance used to set dyes on fabrics forming an insoluble compound with the dye.

A. Background of the study
The background of the study written by the researchers is good. They made mention of the materials used and it's potential as an alternative cement. It is also written in a brief and clear manner.


B. Statement of the Problem
Their statement of the problem is too short and i think it didn't tell the real purpose of the study.


C. Significance of the Study
Their significance of the study is okay but for me it lacks important points which will likely help the readers in understanding their study like the effects of rice hull ash and limestone in their study and they did not state the specific chemical composition that may affect the results of their study which will become a proof to make certain innovations in the industry.

SiGnIFiCaNcE oF The StUdY...

Most plant parts have a mixture of pigments which is where dyes are made.The results of this study maybe used as reference for further improvements in the future. The properties of this project as it's results will try to improve the quality of dyes that are used in dyeing fabrics, coloring and cosmetics industry.

There are different kinds of dyes present in the world , but then those dyes are not abundantly produced in the Philippines , that is why this project is exploring the potential of the plants used to be a possible source of pigments used as dyes to contribute in dyeing.

The different kinds of colors produce different kinds of dyes which helps dyers in simpliflying their work. This project may then reveal the hidden hues and colors of the tested plants to provide a wider range of colors.

bAcKgRoUnD Of ThE StUdy...

Nature presents us an incredible visual rainbow. For centuries, people have tried to capture these natural hues for decorating animal skins, fabrics, crafts, and bodies. Although plants exhibit a wide range of colors, not all of these pigments can be used as dyes. Some won't dissolve in water. It's not obvious from looking at plant colors which will reward us with vibrant dyes - a fact that can lend shades of mystery in dyeing explorations.

A dye can generally be described as a colored substance that has an affinity to the substance to which it is being applied. The dye is generally applied in an aqueous solution and may require a mordant to improve the fastness of the dye on the fiber.

There may be some other ways by which the plants' pigments can be put into use. For this project, it's individual potent will be tested. Since not all of these pigments are found in our country and are not simply attained, selected plants are to be used and their possible colors which are to be explored.

These materials include Carrot(Daucus carota subsp. sativus),Star apple (Chrysophyllum cainito), Mlabar Nightshade (Basella rubra Linn) with their potential color, green. Tomato plants (Solanum lycopersicum) with red and blue, Ube(Dioscorea alata) and Malabar Nightshade (Basella rubra Linn) with purple, and the last would be Carrots (Daucus carota subsp. sativus) with yellow and orange. These plants contain pigments that are possible sources of colors such as carotenoids and chlorophyll.

Extracting the color pigments from plants and testing it's quality against environmental elements to be an alternative source of dyes which in the future be used in cosmetics industry, color, textiles and even in compelling crafts.

sTatEmEnT Of ThE pRobLeM...

This study tries to test whether certain plants(as listed below) can be a possible source of colors used as dyes, and to find out which part of the said plants (stems,leaves,roots,flowers,seeds) produces quality colors against the elements of water, sunlight, temperature etc.

Sample plants with their colors:(possible colors)

Green - Carrot (Daucus carota subsp. sativus)
Star apple (Chrysophyllum cainito)
Malbar Nightsahde (Basella rubra Linn)
Red - Tomato plants (Solanum lycopersicum)
Blue - Tomato plants (Solanum lycopersicum)
Yellow - Carrot (Daucus carota subps. sativus)
Orange - Carrot (Daucus carota subsps. sativus)
Purple - Ube ( Discorea alata)
Malabar Nightsahade (Basella rubra Linn)

Specifically, the study will try to answer the ff. questions:

1. Are the materials attainable?
2.What part of the said plants produces quality colors against environmental elements?
3. Is the intensity of the color produced by such plants good enough to be applied in fibers etc.?
4. Are the colors comparable to the commercial ones?
5. Are the colors produced, can be used as an alternative dye?
6.Will dyes work differently in different types od fabrics?
7. Will different parts of the same plant produce different colors?
