CHAPTER ONE

1.0 INTRODUCTION

In our daily life we use different forms of soap. We cant imagine a single day without theuse of soap. It is an essential part of cleanliness in our civilized society. Soap is an

important surface-active agent and it is chemically the alkaline metal salt of long-chain

fatty acids.

Fatty acid + base soap + water

The most common used fat or oils for production of soap through saponification reactions

are animal tallow, coconut oil, palm oil, kernel oil and linseed oil.

1.1 WHAT IS MEDICATED SOAP?

Medicated soap have the germicidal substance like, Triclosan, trichlocarbon etc. are

incorporated into them, in order to enhance their antibacterial activity.

These germicide substance are normally added in a specified amount and percentage of

the substance used are always stated on the soap case or inside the lesflet which certain

the information on how to use the soap for various purposes.

1.2 HOW DOES ANTIBACTERIAL SOAP WORKS?

Antibacterial soaps contain a special ingredient to kill or control the growth of germs.

When washing with an antibacterial soap, more than 99% of the germs that have been

picked up on the hands are typically eliminated. In contrast, washing with plain soap

initially removes fewer germs through friction, but the germs left on the hands can

quickly regrow, increase in number and spread from person to person.

1.3 WHAT KINDS OF GERMS DO ANTIBACTERIAL SOAP KILL?

Antibacterial soaps kill or inhibit bacteria that cause skin infections, food poisoning,

intestinal illnesses and other commonly transmitted diseases, such as E. coli,

Staphylococci, Salmonella, etc. Their effectiveness can depend on the antibacterial

ingredient concentration, the product formulation and its contact time on the skin. It is

also important to follow the product label directions.

1.4 HOW DO ANTIBACTERIAL SOAPS WORK?

Antibacterial soaps are categorized as over-the-counter (OTC) drugs by the Food and

Drug Administration (FDA) and they are regulated in accordance with the provisions of

the Federal Food, Drug and Cosmetic Act (FFDCA). This requires that they demonstrate

their safety and effectiveness.

Scientists use standard approved clinical and laboratory tests to evaluate the effectiveness

of antibacterial soaps.

Antibacterial hand washes have been shown to reduce the numbers of germs on the skin

to a greater extent than washing with plain soap.

1.5 DESIGN

An antibacterial soap is designed to safely kill germs and cleanse the skin. The formulator

must therefore consider the types of organisms the product should be effective against

and how much time is required for the product to work. The formulator must also

consider factors related to cleansing such as foam quality, speed of foaming, rinsability,

and skin feels, to name a few. In addition, the product's aesthetic qualities (how it looks

and smells) must also be evaluated. The chemist formulating such products must address

all of these factors. The chemist must design the formula, (a recipe which identifies the

ingredients and the quantities used), the manufacturing procedure (which instructs how to

make the product), and the product specifications (which describe the quality of the

finished soap.)

1.6 WHO CURRENTLY USES THEM

Consumers looking for additional protection before preparing and eating meals,

after using the bathroom or diapering a child, after playing with a pet or when

caring for the sick may want to use an antibacterial soap.

Because of the extra protection that antibacterial soaps provide, many restaurants

and hospitals require their employees to wash with antibacterial soap.

1.7 MEDICAL RELEVANCE OF ANTIBACTERIAL SOAP

Antibacterial soap is any cleaning product to which active antibacterial ingredients have

been added. These chemicals kill bacteria and microbes, but are no more effective at

deactivating viruses than any other kind of soap or detergent, and they also kill

nonpathogenic bacteria.

Ingredients: Most liquid hand and body soaps contain antibacterial chemicals. Triclosan

is a common ingredient. Since there is a great variety of bacteria, effectiveness against

any given type of bacterium does not ensure that it is effective against unrelated types.

These are generally only contained at preservative levels unless the product is markedantibacterial, antiseptic, or germicidal. Triclosan, Triclocarban/Trichlorocarbamide and

PCMX/Chloroxylenol are commonly used for antibacterial and deodorant effect in

consumer products. Some soap contains tetra sodium EDTA which is a chelating agent

that sequesters metals that the bacteria require in order to grow. Other microbes also

require metals and so it is actually an anti-microbial agent that is widely used even as a

preservative. It appears to be fairly harmless in the environment.

CHAPTER TWO

2.0 HISTORY

Antibacterial soaps were originally marketed as deodorant soaps to control body odor

caused by the action of bacteria on perspiration. These products, sold in bar form, gained

popularity in the 1950s under such well-recognized brand names as Dial and Lifebouy.

While many of these bar soaps are still available today, liquid antibacterial soaps used for

disinfecting hands are becoming increasingly more popular. Major brands include Lever's

Caress, Dove's Liquid and Proctor and Gamble's Oil of Olay liquid. In addition to these

products intended for consumer use, other antibacterial cleansers are available for use by

health care professionals. Such specialty products include surgical scrubs, wound

disinfectants, and wound cleansers. In the United States, all soaps that make antibacterial

claims are classified as over-the-counter (OTC) drugs because they are sold to kill germs.This designation means they can be purchased without a prescription as long as they

adhere to guidelines set forth by the Food and Drug Administration (FDA). These

guidelines are established in a document known as a monograph which specifies which

active ingredients can be used, the claims that can be made, and so forth. As of 1998, the

FDA has not issued a final monograph on antibacterial soaps, but over the last 25 years

they have published a series of Tentative Final Monographs (TFMs).

The first proposed monograph, published in 1974, officially defined an antibacterial

cleanser as a soap containing an active ingredient with invivo and invitro activity against

skin organisms. It also suggested that antibacterial cleansers be grouped into the

following seven categories: antimicrobial soaps, health-care personal hand washes,

patient preoperative skin preparations, skin antiseptics, skin wound cleansers, skin wound

protectants, and surgical scrub hand soaps. In 1978 the agency issued a TFM which began

formal adoption of the definition and of the categories proposed in 1974. This tentative

monograph allowed products to use terms like deodorancy and reduction of body odor.

Chapter#218181818 5 5 5 5 558181818 5 5 5 5 55

However, this version of the monograph was never finalized, and in 1991 the FDA issued

another TFM with different rules. The 1991 TFM separated first aid antiseptics into a

different category, which included skin antiseptics, wound cleansers, and wound

protectants. Later monographs placed consumer and professional products into separate

categories. Then, in a surprising move in 1994, the agency reversed the earlier tentative

monographs that had recognized antibacterial cleansers specifically for consumers. The1994 TFM does not directly allow antimicrobial soaps for home use. While it does not

disallow these products, it does not set up separate rules for them. Therefore, consumer

products must use the same active ingredients as professional health care products. More

importantly, they are limited to the same types of claims that professional products can

make. This is problematic because consumer products have different requirements than

medical products. For example, deodorant soaps are intended to control body odor while

professional surgical scrub products are not. On the other hand, professional productsmust be safe enough to use up to 50 times per day, whereas consumer products are

typically not used more than two or three times per day. For these reasons and others,

many soap manufacturers believe that consumer and professional products should be

regulated separately. The FDA, however, tends to disagree. The regulatory status of

antibacterial soaps is still tentative; the monograph has not been finalized and industry

experts do not expect it to be ready until after the year 2000.

Today, annual sales of antimicrobial products in the United States have reached $600

million. However, the many antibacterial deodorant bar soaps for controlling body odor

have largely been replaced by antiperspirants/deodorants. The growth in the antibacterial

soap market has come primarily from the increased sales of liquid hand cleansers.

4.0 MEDICATED SOAP ANALYSIS

4.1 DETERMINATION OF SOME PHYSICOCHEMICAL CHARACTERISTICS

Standard analyses are carried out on the soap. The following tests were carried out on

the soap produced.

i. pH

ii. Moisture Content

iii. Total Fatty Matter

iv. Free Alkalinity/Acidity

v. Foam Height

vi. Alcohol insolubility

vii. Microbial Effect

4.1.1 pH DETERMINATION

The pH meter was calibrated using buffer solution of pH between 4.0 and 7.0,

thereafter it was dipped directly into the sample while the reading was taken

immediately.

4.1.2 DETERMINATION OF MOISTURE CONTENT

10g of the sample was weighed and reweighed after open heating for about

30minutes. The difference in weight gives the moisture content which is expressed in

percentage.

4.1.3 DETERMINATION OF TOTAL FATTY MATTER

5g of the sample was weighed into a beaker; 10ml of distilled water was added heated

to dissolve, while 20ml of 2M H2SO4 was added to liberate fatty matter. It was

cooked in a beaker and decanted leaving behind the fatty matter (extract) in the

beaker. The extract was washed with distilled water till it is neutral to litmus paper. It

was then dissolved in 70ml hot neutral alcohol and titrated with 1M NaOH using

phenolphthalein indicator. Total fatty matter (TFM) was then determined as FMV/W

where F is the factor of the oil blended, M is the molarity of the base, V is the volume

of the base used (titer value) and W is the weight of the sample.

4.1.4 DETERMINATION OF FREE ACID CONTENT

6g of the soap sample was dissolved in 70ml hot neutral alcohol and titrated against

2M H2SO4 using phenolphthalein indicator. The free alkali/acidity was calculated as

3.1.MV/W

4.1.5 FOAM HEIGHT

2g of the sample was dissolved in a one liter volumetric flask and made to mark with

tap water, 50ml of the solution was introduce into a measuring cylinder such that it

followed the walls of the column to avoid foaming. 200ml of the solution was taken in

a conical flask and poured into a funnel, which was already clamped with the outlet

closed. The measuring cylinder was then put directly beneath the funnel while the

level (height) of the foam generated was read from the cylinder immediately the

funnel outlet was opened.

4.1.6 ALCOHOL INSOLUBLE

5g of soap sample was dissolved in 50ml hot alcohol and quantitatively transferred

unto already weighed filter paper; the residue was dried in oven at 1050C for

30minutes, cooled in a dessicator and weighed again.

4.1.7 ANTIFULGAL SENSITIVITY

0.1g/ml solution of the medicated soap produced was prepared together with the crude

plant extract. Various dilutions (101, 102, 103, and 104) were also prepared for both

the soap solution and the crude plant extract. The Saboraud Dextrose Agar (S.D.A)

media was also prepared for 10 plates. About 20ml of the S.D.A was poured in each

of the plates. The content in the plates were allowed to solidify after which, the fungi

was placed in the plate (Pour plate method). Hole was made using 10mm diameter
