1. Foaming ability and foam stability: Cylinder shake method was
used for determining foaming ability. 50 ml of the 1% shampoo
solution was put into a 250 ml graduated cylinder and covered the
cylinder with hand and shaken for 10 times. The total volumes of
the foam contents after 1 minute shaking were recorded. The foam
volume was calculated only. Immediately after shaking the volume
of foam at 1 minute intervals for 4 minutes were recorded.
2. Viscosity: This is also an important character and can be measured
by viscometer
1. Effect on hair : This can be studied by half-head technique. In
which half of the hair is shampooed and the other half is used as
control

1. Effect on skin and eyes: This can be measured by applying it on
animals
2. pH : The pH of shampoo can be measured by pH meter and it
should be between 6.0-9.0
3. Stability studies: The thermal stability of formulations was studied
by placing in glass tubes and they were placed in a humidity
chamber at 45 C and 75% relative humidity. Their appearance and
physical stability were inspected for a period of 3 months at interval
of one month.

7. Cleansing action : It can be tested on wool yarn in grease For this
method place 5 gm of wool yarn in grease in 200 ml of water
containing 1 gm of shampoo in a flask, shake the flask for 4 minute
at rate of 50 times a minute. Remove the solution and take out the
sample. Dry it and weigh it. The loss in weight will indicate the
amount of grease removed which is the cleansing action of
shampoo.

• These products are evaluated for the contents estimation and their
identification, also some other tests are required which are to be done
according to purpose.
1. Antiseptic property: This can be done by in-vitro anti
microbiological test against some specific organism using liquid &
solid medium.
2. Stability test: Stability of products and the ingredients must be
studied, particularly that deals with effects of heat & light etc. It is
well known that most of the phenolic materials will discolour on
exposure to light & thus make fair hair, dark particularly in the
presence of traces of alkali or soap.

3. Sensitivity test:
Some of the ingredients like antiseptics may cause irritation,
sensitization or photosensitization of the skin. So these should be tested
and can be done by patch test, either open or occlusive test.

• As chemicals used for hair removers can be toxic, it is necessary to
perform toxicity test along with other test including identification of
ingredients and estimating their quantity.
1. Estimation of hair removing agents: As high concentration of the
chemical hair removers may be dangerous, it is necessary to
remove the quantity. It can be done by any instrumental chemical
analysis.
2. Toxicity test: The test can be done on animal. For this purpose
rabbit can be used . Preparation can be applied for hair removal and
the effect on the skin can be studied by observation or by
microscopic study.

1. Stability: Stability of product is very important . This is done by
any normal stability study or accelerated stability study at higher
temperature.
2. Rheology: Rheology of the preparation can be studied by using any
suitable viscometer.

• As hair colorants can cause sensitization of skin or can produce toxic
effects, it is imperative to do tests for them, apart from normal
quantity test for ingredients and their quantity.
1. Sensitization test: This can be done on the animal skin by applying
dye stuff or the preparations and observing the effect on the skin. It
is necessary , histopathological study of the related tissues or cells
can be done when applied.
2. Long term toxic effect: This is also necessary to evaluate the long
term effect. This can be done on animal.

1. Stability of the ingredients: This is done by normal stability study,
of the active ingredient at room temperature or by accelerated
study.
2. Physical stability: This is particularly important for emulsion type
preparations to evaluate the stability of the emulsion creams. This
can be done by accelerated test by exposing the preparation
alternatively to heat and cold.
3. Rheology: Studied by using viscometer to measure the viscosity &
effect of storage on it.

• It is necessary to measure the quantity of chemical agents present in
the preparations, as use of higher concentration is toxic and is not
permitted by several countries.
1. Toxic or side effect: Several tests are required to evaluate the toxic
effects, the effects can be scalp irritation, incompatibility due to
cross sensitization leading to dermatitis. This can be done on
animal or by patch test.
2. Stability test: To test the stability and usefulness of the product
during shelf-life or when several ingredients are present. This can
be done by normal stability test or by accelerated stability study
