This document provides information on the key components of shampoos. It defines shampoo as a preparation containing surfactants that will remove dirt from hair without harm. The main ingredients include anionic surfactants, conditioning agents, thickeners, preservatives, and fragrances. Different types of shampoos are described such as liquid, lotion, and conditioning varieties. Guidelines for evaluating shampoos involve testing for solid content, pH, viscosity, foaming ability, skin/eye irritation, cleaning effectiveness, and packaging/labeling requirements.

4. Definition :
A shampoo is a preparation of surfactant in
a suitable form liquid, solid or powder
which when used under the specified
conditions will remove surface grease, dirt
& skin debris from the hair shaft & scalp
without adversely affecting the user.

5.  It should produce a good amount of foam.
 It should be easily removed on rinsing with water.
 It should impart a pleasant fragrance to the hair.
 It should not cause any side effects / irritation to the skin or eye.
 It should effectively or completely remove dust or soil.
 It should not make the hand rough.

6. INGRIDIENTS FOR SHAMPOO
 Surfactants
Surfactants are the main component of shampoo. Mainly anionic surfactants are used.
Anionic Surfactants:
Anionic surfactants are mostly used (good foaming properties). The hydrophilic portion carries
a negative charge which result in superior foaming & cleaning. e.g. Lauric acid, stearic acid.
Non-ionic Surfactants:
Non-ionic Surfactant have good cleansing properties but do not have sufficient foaming power.
e.g. Sorbitol esters (TWEENS), Ethoxylated fatty alcohols, Lauric monoethanolamide.
Amphoteric Surfactant:
Amphoteric surfactants carry positive and negative charge they are mainly used as secondary
surfactant & good hair conditioners. e.g. β – amino acid derivatives, Asparagine derivatives.

7.  Conditioning agents
They are intended to improve manageability, feel & lusture of hair.
e.g. Lanolin, Mineral oil, Polypeptides, Egg derivatives, Herbal extracts
 Viscosity modifier
They are used to improve the thickness of compounds.
(a) Electrolytes : Ammonium chloride, Sodium chloride
(b) Natural gums : Gum Tragacanth, Gum karaya, Alginates
(c) Cellulose derivatives : Hydroxyethyl cellulose, Hydroxypropyl cellulose
(d) Carboxyvinyl polymers : Polymer of acrylic acid cross-linked with
polyfunctional agent
 Opacifying & Clarifying agents
Stearyl alcohol, Propylene glycol, Phosphates, Finely dispersed zinc oxide
Milky emulsions of vinyl polymers. 7

8.  Preservatives
Bacterial growth in shampoo can lead to breakdown of detergent i.e.
resulting in discoloration of product hence preservative are important in
product.
e.g. Formaldehyde , Esters of para hydroxy benzoic acid
 Perfumes
There are two important aspects before final selection of fragrance for
shampoos.
a) Fragrance must be soluble in shampoo
b) It must be compatible with shampoo i.e. not affect the viscosity &
stability.
e.g. Herbal, fruity & floral fragrance.

9. TYPES OF SHAMPOO
Shampoos are of the following types:
 Powder shampoo
 Liquid shampoo
 Lotion shampoo
 Cream shampoo
 Specialized shampoo
 Conditioning shampoo
 Anti-dandruff shampoo
9

10.  Powder Shampoo
Powder shampoos were used earlier because of the trouble involved in
using them and because they leave hair in poor condition.
Formula:
 Liquid Shampoo
Formula:
Henna powder - 5%
Soap powder - 50%
Sodium carbonate - 22.5%
Potassium carbonate - 7.5%
Borax - 15%
Perfume - Q.S
Sodium lauryl sulphate - 40%
Sodium chloride - 2-4%
Water - upto 100%
Perfume, Colour & Preservatives - Q.S

11.  Lotion Shampoo
Formula:
 Conditioning Shampoo
Conditioning molecules contained in shampoos combine the cleansing
action with the function to impart manageability, gloss and antistatic
properties of hair.
Formula:
Sodium lauryl sulphate - 35%
Glyceryl monostearate - 2%
Magnesium monostearate - 1%
Water - upto 100%
Colour, Perfume & Preservatives - Q.S
Stearyl dimethyl benzyl ammonium chloride - 5.5%
Ethylene glycol monostearate - 2%
Cetyl alcohol - 2.5%
Water - upto 100%
Color, Perfume & Preservatives - Q.S

12. EVALUATION OF SHAMPOO
1. Determination of percent of solid contents :
 A clean dry evaporating dish was weighed and added 4g of shampoo to it.
 Evaporating dish with the shampoo was weighed.
 The exact weight of shampoo was calculated & the evaporating dish with the
shampoo was placed on a hot plate until the liquid portion evaporates.
 The weight of shampoo only (solids) after drying was calculated.
2. Determination of pH :
 The pH of 10% shampoo solution in distilled water was determined at room
temperature using a digital pH meter.

13. 13
3. Determination of viscosity :
 It is determined using Brookfield viscometer .
 100ml of shampoo is taken in a beaker & spindle is dipped in it for
about 5 minutes and then reading is taken.
4. Foaming ability & Foam stability :
 50ml of 1% shampoo solution was put into a 250ml graduated
cylinder and covered the cylinder with hand and shaken for 10 times.
 The total volume of the foam contents after 1 minute shaking were
recorded.
 The foam volume was calculated after shaking the volume of the
foam at 1 minute interval for 4 minutes were recorded.

14. 5. Skin irritation test :
 Patch test technique is used here.
 A set of 6 rabbits were used for testing each material.
 The shampoo preparations are diluted between concentrations of 8-10%.
 Patches containing the shampoo preparations were applied & then removed , the
skin sites were noted for any changes on the surface of skin like edema, erythema
formation.
 These products are then classified as mild irritant, moderate & severe.
6. Cleaning action :
 5g of wool yarn were placed in grease , after that it was placed in 200ml of water
containing 1g of shampoo in a flask .
 Temperature was maintained at 35ºC .
 The flask was shaked for 4 minutes at the rate of 50 times a minute 14

15. Continue..
 The solution was removed and sample was taken out, dried and weighed &
calculated the amount of grease removed.
7. Eye irritation test :
 About 1% shampoo solution was dripped into the eyes of 6 rats with their eyes held
open with the clips at the lid.
 The progressive damage to the rabbit’s eyes was recorded at specific intervals over
an average period of 4 seconds.
 Reaction to the irritants can include swelling of the eyelid , inflammation of the
iris, ulceration , hemorrhaging and blindness.
