BACKGROUND OF THE INVENTION 10

Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Good health is a result of effective maintaining of personal hygiene. Maintaining 15 good personal hygiene consists of bathing, washing your hands, brushing teeth and sporting clean clothing. Soaps play an important role in maintaining good personal hygiene irrespective of age and gender. Soap is generally a salt of a fatty acid and product of saponification.
[0004] Saponification of fats and oils is the most widely used method in the process of 20 preparing commercial soap. This method involves heating fats and oils and reacting them with a liquid alkali (lye) to produce soap and water (neat soap). Apart from oil and lye, moisture retaining agents, colouring agents, flavouring agents, etc., are used to get a pleasant soaps.
[0005] Various soaps are available in commercial market and they are synthetic as well 25 as herbal with several benefits apart from its cleansing property. Currently, people are very much interested in using herbal soaps over the synthetic soaps because of less or no side effects in herbal soaps. It is also believed that anything natural will be promisingly safe to be used and does not produce any harmful effect on skin.
[0006] There is, therefore, a need to develop a safe and effective polyherbal soap 30 composition suitable for all skin types and a single soap for both cosmetic and therapeutic purpose. - 2 -

Preparation of poly herbal soap:
(a) Weighed amount of coconut oil, castor oil, neem oil and mentha oil were poured in a beaker and mixed well to obtain an oil mixture.
b). Rose petal extract was weighed separately and mixed well in distilled water in a separate 5 beaker.
c). 6g of NaOH was dissolved in 10 ml of distilled water in a beaker and added the rose petal extract solution and mixed well under stirring to obtain mixture of lye and rose extract solution.
d). The mixture of lye and rose extract solution was then poured into the oil mixture 10 obtained in step (a) with continuous stirring on a magnetic stirrer under room temperature to obtain a soap solution mixture.
e). The soap mixture obtained in above step (d) was then allowed to solidify and kept at room temperature to obtain the polyherbal soap.
[0066] The polyherbal soap obtained was analyzed for pH, moisture content, foaming 15 index, foam retention time, saponification, TFM determination and ethanol soluble matter using different concentration of soap solution comparing with standard. The results demonstrated that the polyherbal soap obtained has the following properties:
1. pH= 6.5 – 7;
2. Moisture content = 3.5%; 20
3. Foam index = 16.5;
4. Foam retention time = 10.0 minutes;
5. Saponification value = 161.287 mg/ml;
6. TFM = 72%; and
7. Ethanol soluble matter = 63.80%. 25
[0067] Example 2: Evaluation of Antimicrobial activity
The polyherbal soap obtained above was subjected to antimicrobial test using agar well diffusion method. Antibacterial property was evaluated for the prepared soap by agar well diffusion method. Microorganisms used were E. coli. and S. aureus. About 1g of soap was mixed in sterilized water. Different concentrations of the soap solutions were 30 prepared (25, 50 and 75 %). The standard antibiotic ciprofloxacin (5 μg) was taken to compare antibiotic potential. The plates were incubated for 24 hours at 37 ºC and zone of inhibition was calculated as shown in the table given below. - 12 -
