This document provides information about formulating and evaluating shampoos. It discusses the key ingredients in shampoo like surfactants and additives. Various shampoo formulations are presented, including liquid, lotion, cream, jelly, aerosol and specialized formulations. Methods for evaluating shampoos are outlined, focusing on foam and foam stability, detergency, rinsing, conditioning action, and microbiological assays. The document serves as a guide for formulating different types of shampoos and assessing their performance.
Shampoo
Human Hair Structure
Introduction
Shampoo is a hair care product that is used for the removal of oils, dirt, skin particles, dandruff, environmental pollutants and other contaminant particles that gradually build up in hair.
Introduction

Functions of Shampoo
Classification
Classification
Based on Appearance:
Powder Shampoos
Liquid Shampoos or Lotion
Gel Shampoos or Solid Cream
Classification
Classification
II. Based on Use or Function:
Conditioning Shampoos
Antidandruff and Therapeutic
Baby
Balancing
Clarifying
Classification
III. Based on Origin:
Compositions
Shampoos are typically composed of 10 to 30 ingredients.
Several types of ingredients are particularly important, including “Surfactants" that aid in cleansing and lathering.
“Conditioners" and “Active ingredients" that affect the hair and scalp.
“Additives" that stabilize the product.

Manufacturing Process
Some pearlising agents are waxy solids at ambient temperature and require melting in a drum oven or similar before use.
Demineralised water is most commonly used in order to minimise contamination of the product.
No further processing is required after blending, and the product may be packed off directly from the mixing vessel.
Manufacturing Process
For preparing liquid shampoo,
Triethanalamine lauvyl sulfate,
stearic acid are heated to about 650C.
Water & preservatives are also heated to 650C.
Both the solutions are mixed together and then cooled.
Perfumes are added after that. The shampoo thus prepared is bottled by automatic bottle filling machine.
Quality Control Tests
a)Foam Stability
Cylinder shake method was used for determining foaming ability.
50ml of the 1% shampoo solution was put into a 250ml graduated cylinder and cover 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. Foam should retain for atleast 5mins.
Foam Stability = V2-V1
Quality Control Tests
b)Skin – irritation Test:
Draize test in Rabbits where a patch test technique is used on the intact skin of Albino Rabbits.
A set of 6Rabbits used for testing each material.
Shampoos should be tested only for a short duration thatis,not more than(NMT)4hours as these products come in contact with skin only for a short duration.
These preparations are diluted between concentrations of 8 to 10%.
Quality Control Tests
c)Wetting Action:
Canvas disk is used, is one inch in diameter is floated on the surface of a solution and the time required for it to sink is measured accurately.
Quality Control Tests
d)Viscosity:
Is determined using Brookefield Viscometer.
100ml of shampoo is taken in a beaker and spindle is dipped in it for about 5min and then reading is taken.
