Activated carbon; Dandruff; Dirt; Herbal shampoo
Hair is one of the external barometers of internal body conditions. It is an important part of human body. Various synthetic compounds, chemicals, dyes and their derivatives have been proved to cause harmful effects. Nowadays, people are having an awareness of their effects on hairs skin and eyes. Due to these reasons the community is attracted towards herbal products due to their inexpensive nature and negligible side-effects. Herbal cosmetics are denoted as products formulated using various permissible cosmetic ingredients to form the base in which one (or) more herbal ingredients are used to provide accurate cosmetic benefits. Nowadays, the usefulness of herbs in the cosmeceutical production has been extensively increased and there is a great demand for the herbal cosmetics. As far as the herbal shampoos are concerned in stability criteria, depending upon the nature of the ingredients, they may be simple (or) plain shampoo, antiseptic (or) antidandruff shampoo and nutritional shampoo containing vitamin, amino acids, proteins hydrolysate. The selection of active ingredients for hair care powders is based on the ability of the ingredient to prevent skin damage as well as to improve the quality of skin by cleansing, nourishing and protecting the skin. In this study, formulation and evaluation of herbal shampoo powder is reported.
The objective of the present research work is to develop an herbal shampoo powder with activated charcoal which clears sebum, dirt, dandruff, promotes hair growth and strengthens hair. Moreover, it also acts as a conditioning agent. This herbal shampoo powder performs all these actions without affecting or damaging hair [1-6].

Evaluation of Herbal Shampoo
Colour: The colour of the herbal.
Texture: The texture of the shampoo is observed. shampoo is observed and noted.
Odour: The odour of the shampoo is observed.
pH: 5% shampoo solution is taken and determined the pH using pH meter at room temperature.
Active matter: 2.2 g of the sample is weighed accurately and it is made up to 250 ml by addition of distilled water in a standard flask. It is shaken well and allowed to dissolve for some time. After few minutes 10 ml of the sample is pipetted out. Standardized benzethonium chloride solution is filled in the burette. 0.05 gram of methylene blue, 50 grams of sodium sulphate and 68 ml of concentrated sulphuric acid is dissolved in water, methylene blue solution is prepared. This methylene blue solution is used as the indicator. This methylene blue solution is added to the pipetted-out sample. 0.5 ml of benzethonium chloride solution is added slowly from the burette. The cylinder is stoppered and shaken well after each addition. The phases can separate. Initially the chloroform phase is coloured blue or greenish blue. Towards the end the colour started to migrate to the aqueous layer. The colour intensity in both the phases is same when viewed under standard conditions of light is noted.
The anionic active matter as sodium alkyl benzene sulphonate is calculated as:
Anionic active matter,
Percent by mass=342 × V × M × 5 ÷ m
342: Molecular mass of sodium alkyl benzene sulphonate taken for calculations
V: Volume in ml of benzethonium chloride solution added
M: Molarity of benzethonium chloride solution
M: Mass in g of the sample taken.
Non-volatile alcohol soluble matter: 2 g of sample is taken and 50 ml of 95% ethanol is added to it. The sample is soaked in the solution for 5 minutes. The mixture is then heated in a water bath for 15 minutes. After some time when all the alcohol soluble matter is dissolved, the solution is filtered to remove the remaining insoluble matter in a crucible. The empty weight of the crucible is noted before. The weight of the crucible along with the residue is noted and allowed to dry for 1 to 2 hours in an autoclave at 95°C. The final weight of the crucible is noted after drying. It is calculated as:
Percentage of Non-Volatile Alcohol soluble matter=(x?y × 100) ÷ z
x: Weight of the sample
y: Initial weight of the empty crucible
z: Final weight of the crucible with residue.
Foam height: 2 g of the sample is weighed accurately and mixed in 100 ml of distilled water. The mixture is taken in a 500 ml graduated cylinder and it is shaken for 50 times. The test is carried at room temperature. The foam is formed due to the foaming ability and its height is noted.
In water base: 2 g of the sample is weighed accurately and mixed in 100 ml of distilled water. The mixture is taken in a 500 ml graduated cylinder and it is shaken for 50 times. The test is carried at room temperature. Foam is formed due to the foaming ability. The formed foam retention time is noted.
In ethanol base: 0.3 g of the sample is weighed. The sample is added to an ethanol solution (99.9% ethanol 5 ml and water 25 ml). The mixture is taken in a 100 ml graduated cylinder and it is shaken for 20 times. Foam is produced. The foam retention time is noted.
A pinch of shampoo is taken in a large test tube. 10 ml of distilled water is added to it. 1 drop of India ink (blue ink) is added to the mixture. The test tube is stoppered and shaken for ten times. The amount of ink in the foam is estimated as (None, Light, Moderate, or Heavy) and recorded.
The yeast and mould are cultured for a five day. The samples with various carbon proportions are added to this culture and their reduction count is noted after two days. The base count is 12,00,000 cfu/g.
Critical Micelle Concentration
In colloidal and surface chemistry, the Critical Micelle Concentration (CMC) is defined as the concentration of surfactants above which micelles form and all additional surfactants added to the system go to micelles. The CMC is an important characteristic of a surfactant.
The sample is weighed and taken in five different proportions. 50 ml of distilled water is mixed in each proportion. This mixture is taken in a measuring cylinder and is shaken 20 times. Foam is produced in various heights for various concentrations. These heights are measured and the graph is plotted for concentration vs. foam height. Initially for increasing concentration the foam height is also increasing. After a concentration the foam height is found to be decreasing. The maximum foam height achievable is found from the graph. The corresponding concentration is the Critical Micelle Concentration (CMC) for the sample.
Results and Discussion
The result of visual inspection for all the shampoo powders are observed and evaluated for colour, odour, taste and in terms of their appearance, flow property and texture. They showed distinct change in colour. The results are reported in Table 2.
|Evaluation parameters||Sample 1||Sample 2||Sample 3|

Table 6. The evaluation of foam height.
Foam stability: In Water Base: The composition of activated carbon did not alter the foam stability of the shampoo. 30 minutes is the noted time which lies within the required standards.
In ethanol base: 25 minutes is the noted time. The foam which is stable in ethanol base can be used in soil remediation. Here the foam produced, irrespective of carbon content is stable on diluted ethanol base. So, it can be used in the process of soil remediation.
Dirt dispersion: The dirt dispersion ability increased as the concentration of the charcoal increased in the shampoo. It is shown in Figure 2.
The reduction count of microbes is found to be high, as the concentration of the activated charcoal in the shampoo is increased. The result is reported in Table 7.
|Herbal shampoo 1||900000||cfu/g|
|Herbal shampoo 2||600000||cfu/g|
|Herbal shampoo 3||200000||cfu/g|

Critical Micelle Concentration
The CMC is studied and a graph is plotted. The result is shown in Figure 3.
Activated carbon is applied in various fields due to its adsorption capacity and dirt removing capacity. In this paper usage of activated carbon in effectively removing dandruff and dirt is discussed. Based on the results obtained from the tests, it could be interpreted that usage of activated carbon in shampoo in various compositions yield better results in dandruff treatment and dirt dispersion. Since it is used along with herbs, the shampoo does not have any side effects.
