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

Result

Phase A	Phase B	Phase C
15 ml castor oil	2.0 g white beeswax	2-3 drops Paraben
Pigments used	1.3 g cocoa butter	(0.1 % methyl paraben solution
	1.6 ml vitamin E acetate
	0.8 g Vaseline
	0.9 ml honey (for taste)

Phase A :

Formulation	Types of pigment	Mass (g)
1	Red	1.5
	Blue	0.5
2	Purple	0.5
3	Red	0.5
4	Blue	0.5
	Red	1.0
5	Silver	0.6
	Red	0.5
6	Gold	0.1
	Carmoisine	15 drops

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.
