containing a suitable blend of oils, fats and waxes suitably perfume,
flavored and moulded in the form of stick and enclosed in a case.
Base – emollient action
4. CHARACTERISTICS:
It should be smooth and easy to apply leaving a thin film on lips.
It should have a good degree of indelibility.
It should have high retention of colour intensity.
It should be free from grittiness and should be non-drying.

7. Manufacture of lipsticks:
Steps involved is:
Melting and mixing.
Moulding.
Labelling and packing.
DEFECTS IN LIPSTICKS
8. EVALUATION OF LIPSTICK:
Colour control,
Determination of melting point(heat test),
Softening point,
Microbial testing,
Rancidity,
Rupture test,
Breaking load test.
9. Colour control:
Colour control of lipstick is critical ,
manufacture to be aware of this.
Colorimetric equipment is used to provide some control on the
shades of lipstick.
This equipment gives a numerical reading of the shade, when
mixed, so it can identically match previous batches.
11. SOFTENING POINT:
A lipstick should withstand the range of conditions to
which it will subjected in the consumers handbag.
It should be resistant to varying temp & be just as easy to apply in
the hot as in cold weather.
Softening point range 50-550C.
Method: Ring and Ball method Second Method.
12. Microbial testing:
Contamination from raw materials, moulds, storage kettles or
lipstick container can lead to microbial growth.
The test consist of plating a known mass of the sample on two
selected culture media specifically suitable for the growth of
bacteria fungi incubating them for a specified period to permit the
development of visual colonies for counting.
The limit is, not more than 100 µo/gm
13. Rancidity:
Rancidification is the decomposition of fats, oils and other lipids by
hydrolysis or oxidation.
It leads to obnoxious odour, bad taste & sticky product &
sometimes change of colour of the product.
Testing of rancidity can be done by determining its peroxide
number
14. Breaking load test:
• The test is to find out the value of
maximum load that a lipstick can
withstand before it breaks.
• The protruded lipstick salve is subjected
to a number of weights hanging from it.
• The weight at which the lipstick
breaks is its Breaking Load
15. FACTS:
First manmade lipsticks appeared around four to five thousand
years ago in Ancient Mesopotamia.
80% of the American women regularly wear lipstick and over 25%
won’t leave house without wearing it.
Lipsticks can contain fish scales, and castor oil that provides lips
with shiny film that can’t be smeared easily.
During dark and middle ages in Europe, lipsticks were often
viewed as a fashion accessory of prostitutes and lower class
women.
One of the most expensive lipsticks in the world is
Guerlain’s KissKiss Gold and Diamonds Lipstick, which will set
you back $62,000.
