Polyherbal soap was prepared by using sandal wood and Orange peel extract and evaluated by using various evaluation parameters such as organoleptic characteristics, pH, foam height and retention, skin irritation and high temperature stability. Prepared Polyherbal soap having good appearance better cleansing and foaming effect and doesn’t have any side effects.


KEYWORDS: Polyherbal soap, cleansing, foaming. 




Herbal cosmetics are prepared by the association of bioactive ingredients and pharmaceutical products. The presence of number of photochemical and botanicals in the herbal products have dual significance, one that they are used as cosmetics for body care and another that photochemical improve the biological functions of human body naturally results in healthy skin. As the realization said that the chemical medicines are not always work as magic bullets and they may have side effects. The current trend moves toward the herbalism and use of natural products. Indian herbs are the richest source to be used in cosmetic industries. Herbal cosmetics were gaining tremendous demand in the world market. There is a wide range of herbal cosmetic products used as beauty regime to satisfy the purpose of beautification.


Soap is sodium or potassium salt of fatty acid produced by saponification reaction using sodium or potassium hydroxide.



Based on its chemical properties as an anionic surface active agent (surfactant), soap is used to clean and wash skin and clothing. The soap that are being used in our day to day life have a history going back for about six thousand years. The ancient Babylonians discovered that mixing animal fats with wood ash and water created a cleansing substance which was latterly known as “soap”. In today’s world more and more people are looking for natural solutions to some of the products they are using, especially when it comes to their bodies.


Just as doctors are promoting a healthier lifestyle by choosing natural foods to put in our body, others are becoming more aware of things they are using on the outside of their bodies. As people begin to look toward natural products, as an alternative to commercial soaps with all their additives, more and more they are turning to natural soaps. People who are suffer from skin conditions, herbal soaps will help to control conditions such as cane, psoriasis and eczema.


There are basically four different types of methods that are used to make soaps are

·       The melt and pour process:

In this process simply a glycerin base is used, there is not usage of lye. Its easy, not dangerous you may add essential oils or fragrance to your mixture, as well as some coloring.

·       Cold process soap:

These processes involve addition of lye or sodium hydroxide and water.


·       Hot process soap:

Hot process of soap making simply involves using heat, in order to burn off excess liquid.

The basic soap bases


1.     Glycerin soap base:

Glycerin soap bases can come in clear, white or vegetable. This soap bases is more often used in melt and pour soaps, than in other kind of soap,


2.     Lard:

Lard is another soap base. It’s also known as one of the most popular bases, as it produces a thick creamy lather, has conditioning  properties.


3.     Soap chips:

These are a common base used for liquid soap.



Saponification is a process that involves conversion of fat or oil into soap and alcohol by the action of heat in the presence of aqueous alkali (e.g. NaOH). Soaps are salts of fatty acids whereas fatty acids are saturated monocarboxylic acids that have long carbon chains (at least 10) e.g. CH3(CH2)14COOH.


Vegetable oils and animal fats are the traditional materials that are saponified. These greasy materials, triesters called triglycerides, are mixtures derived from diverse fatty acids. Triglycerides can be converted to soap in either a one- or a two-step process. In the traditional one-step process, the triglyceride is treated with a strong base (e.g. lye), which cleaves to the ester bond, releasing fatty acid salts (soaps) and glycerol. This process is also the main industrial method for producing glycerol. In some soap-making, the glycerol is left in the soap. If necessary, soaps may be precipitated by salting it out with sodium chloride. Structure of soap


Skeletal formula of stearin, a triglyceride that is converted by saponification with sodium hydroxide into glycerol and soap. Fat in a corpse converts into adipocere, often called "grave wax". This process is more common where the amount of fatty tissue is high and the agents of decomposition are absent or only minutely present.

1.     The required quantity of oils were weighed and mix together and heated until it get melt and mix properly

2.     Simultaneously the required quantity of lye is dissolved in water.

3.     Then the solution of lye were added into the mixture of oils slowly with vigorous stirring until the saponification reaction takes place.

4.     After the formation of thick homogenous mixture the remaining amount of  ingredients like orange peel powder  extract, sandalwood powder extract, one tablespoon of honey and lemon oil were added to the mixture and stirred the mixture for  some time.

5.     Then this mixture was poured into the molds and covered with aluminium foil kept for 24 hrs in refrigerator.
