3. • Shaving cream is a substance applied to the skin
to facilitate removal of hair.
• Shaving cream provides lubrication which helps
prevent razor burn and discomfort during
shaving. It comes in a wide variety of formats
including creams, gels and most commonly
foams.

4. IDEAL PROPERTIES
• It must be non-irritating to the skin.
• It must soften the beard so that the hair are cut easily.
• It must retain moisture during the period it remains on
the face.
• If it is to be used with a brush, it should be able to
develop high lather rapidly.
• It should be non-corrosive to the container in which it is
packed.
• It should be stable over wide range of temperatures.
• It should have sufficient viscosity to hold individual hair
erect so that it could be cut close to the skin surface.

5. SHAVING SOAP
• Definition:-
• Shaving soaps typically refers to a hard soap that is
• whipped into a lather using a shaving brush.
• History:-
• Hard shaving soaps in their modern form have
existed
• since at least the early 19th century.
• Shaving soaps can be presented in bar, stick or cup
• formulations.

7. MANUFACTURING
• The solid shaving soap can be made in crutcher using
a mix of sodium and potassium hydroxide. The glycerin
that is produced from fats is used in in the finished
cake. Thus, the product has shiny or sticky feel.
• To make cake shaving soap a kettle-made boiled soda
• soap can be used.
• For making shaving stick or shaving bowl soap, it is
• advantageous to use plodder of great packing power.

8. LATHER SHAVING CREAM
Definition::
• Lather shaving cream is defined as a mixture of soap
in glycerin and water.
Characteristics:-
• It should produce rich and copious lather.
• It should be non-irritant to the skin.
• It should be smooth, soft and free from lumps.
• It should have good wetting properties.

10. MANUFACTURING
• Oils/fats are melted and filtered and are saponified
• with soda lye in presence of glycerin.
• Melted stearic acid is added with slow stirring.
• The cream is then superfatted with boric acid, etc.
• Heating is stopped and stirring is continued till the
• cream cools.
• When the temperature drops to 40-45C, perfume is
• added. The cream is allowed to stand for 3-4 weeks
• before packaging.

11. BRUSHLESS SHAVING CREAM
Definition:-
• Brushless shaving cream, as the name suggests does
not require brush for applying. The cream is applied
and spread with fingers.
History:-
• The method was popularized in the United States
after the First World War.

13. MANUFACTURING
• The standard method is to heat water and water-
soluble ingredients to 65-70C and add to the molten
oil and fats heated to the same temperature with
stirring.
• Cream is cooled to about 45C and perfume is added.
• The cream is then allowed to mature, this period
varies from 24hrs to a week.

14. AEROSOL SHAVING LATHERS
• Aerosol shaving foams are o/w emulsions. When the
preparation is discharged to the atmosphere, droplets
of propellant vaporize producing vapor bubbles
surrounded by aqueous surfactant phase.

15. MANUFACTURING
• Saturated fatty acids are main components of aerosol
shaving cream and so used in proportion of 7-9%.
• Alkali likes potassium hydroxide may be used. The
quantity of alkali is so adjusted that the formulation
contains 1-3% of free fatty acids.
• Humectants such as glycerol, sorbitol are added in
• concentrations upto 3-10%.
• Lubricants—Ro make passage of the razor over the face
• easy. Proportions used 1-2%.
• Propellants:- fluorocarbons(7-10%), etc. propellants
used to lower the foam density.
• Soap compatible perfumes are used (0.15-0.65%).
