Introduction:Introduction:

What is Creams?

Answer- Creams are thought of as ointments but usually contain a water soluble base due to which they can be easily removed from the skin. When applied to the skin, leave no visible evidence of their presence on the skin.

What is shaving ?

Answer- Shaving is the removal of hair, by using a razor or any other kind of bladed implement, to slice it down to the level of the skin.

Is it necessary ( Scientifically ) ?

Answer – No ,it is not necessary . There are many peoples in the field who have never think of shaving their hairs . Infect a lot of your body hair though is to help keep you cool, keep dirt out of certain areas, and can also help you to feel things when something moves or touches them.

Shaving cream is applied to the skin to facilitate

removal of hair. Shaving cream softens and

moistens the skin and the hair, thus making shaving

more comfortable and contributing to smoother

skin.

Shaving Cream:Shaving Cream:

Shaving Cream achieve three effects: lubricate the

cutting process; swell keratin and desensitize skin.

Shaving creams commonly consist of an emulsion of

oils, soaps or surfactants and water.

Shaving cream that are in tubes are commonly used

with a shaving brush to produce a rich lather.

History:History:

A rudimentary form of shaving cream was documented in

Sumer around3000 BC. This substance combined wood

alkali and animal fat and was applied to a beard as a

shaving preparation.

Until the early 20th century, bars or sticks of hard shaving

soap were used. Later, tubes containing compounds of oils

and soft soap were sold. Newer creams introduced in the

1940s neither produced lather nor required brushes, often

referred to as brushless creams.

History:History:

Modern commercial creams are often sold in spray cans,

but can also be purchased in tubs or tubes.

Shaving creams in a can are commonly dispensed as a

foam or a gel.

Creams that are in tubes or tubs are commonly used with a

shaving brush to produce a rich lather (most often used in

wet shaving).

Classes Of Shaving PreparationClasses Of Shaving Preparation::

Shaving Soaps:Shaving Soaps:

Shaving soap typically refers to a hard soap that is whipped

into a lather using a shaving brush.

Combination of coconut oil soaps & palm oil soaps for quick

& stable lathering.

Within each there is a combination of potassium & sodium

soaps to get quick lathering & maintain the body of soap.

Supper fatting agents & talc are also employed.

recent innovation lies in the use of haemostatic materials .

Shaving PowdersShaving Powders::

Popular with the barbers.

Powder easily dispensed into shaving mug prior to

addition of water and production of lather using shaving

brush.

Product claimed to more sanitary because fresh

quantity of powder was used every time.

Shaving SticksShaving Sticks::

Generally not popular among customers but it exist

Formulation logic is same as that of soap but this

one is more enriched in soaps.

Once formulation existed in 1939 with alkali

peroxide as an ingredients.

Lather Shaving Cream:Lather Shaving Cream:

Have same ingredients as that of soap with inclusion

of greater amount of water to give creamy

consistency.

Playing with the ratio of Na/K soaps not only affect

lather but also consistency and stability of cream.

Supper fatting agents and borax are added to

maintain stability.

Brushless Shaving Cream:Brushless Shaving Cream:

Not meant to produce foam

It is o/w emulsion.

Comfortable shave is because of greater lubricating

ability and subsequent reduction in razor pull or drag.

Leaves face with thin coating of oil.

Wetting agents are employed to improve beard

softening.

Raw Materials:Raw Materials:

A standard recipe contains approximately i. Aqua/water

ii. Stearic Acid,

iii. Triethanolamine,

iv. Lanolin,

v. Glycerin,

vi. Polyoxyethylene sorbitan monostearate,

vii. Laureth 23,

viii. Lauryl Sulfate,

ix. Waxes and cocamides.

x. Methyl paraben

xi. Ethyl paraben


Two major ingredients in this formula are common in many of

today's preparations.

Stearic acid is one of the main ingredients in soap making, and

triethanolamine is a surfactant, which does the job of soap.

Lanolin and polyoxyethylene sorbitan monostearate are both

emulsifiers which hold water to the skin,

While glycerin, a solvent and an emollient, renders skin softer

and more supple.


Common substitutes for the third, fourth, and fifth ingredients listed

above include laureth 23 and lauryl sulfate are both sudsing and

foaming agents.

Waxes and cocamides which cleanse and aid foaming.

Most ingredients are powdered or flaked, although lanolin, lanolin

derivatives, and cocamides are liquids.


The differences between one brand of shaving cream and

another amount to adjustments in the proportions of

ingredients and in the processing method and choice of

ingredients such as emulsifiers or perfumes. Also important

is the choice of aerosol propellant. Some mixtures contain

more than one propellant; most common are butane,

isobutane and propane.

The Manufacturing Process:The Manufacturing Process:

The modern manufacture of shaving cream is a carefully controlled

process. There are two main phases to the manufacturing

process.

1. In the first phase, the fatty or oily portions of the formula—stearic

acid, lanolin, and polyoxyethylene sorbitan monostearate—are

heated in a jacketed kettle to a temperature of approximately 179

to 188°F (80 to 85°C) for 40 minutes.

2. Then the steam is released from the outer container of the kettle,

and the mixture is allowed to cool.


3. The second phase of manufacture begins when the mixture has

cooled to about 152°F (65°C). Most of the remaining ingredients

—water, glycerin and triethanolamine—are added now, and

mixing continues for approximately 40 minutes.

4. When the mixture reaches a temperature of 125 to

134°F (50 to 55°C), preservatives and perfumes or

other scents can be added. Because perfumes

consist primarily of highly volatile oils, they would

evaporate if added when the blend was still warm.


5. The mixture, still being stirred, is allowed to cool

further, until it reaches a temperature of 89°F (30°C).

6. Then the mixture is ready for filling and sealing.

Quality Control:Quality Control:

o Today's soaps, shaving creams, and lotions are all manufactured

under strict quality control, and regulated by various federal

agencies including the Food and Drug Administration (FDA).

o Batches of shaving cream are examined and analyzed both at the

manufacturing site and in the laboratory. Individual containers of

shaving preparations are coded so that a manufacturer knows

exactly which batch any given can or tube came from, and can

identify its distribution history.

Quality Control:Quality Control:

o A manufacturer of shaving cream needs to be certain that

each batch meets quality standards. Among the things

tested for are pH value (the acidity or alkalinity of the

product). The pH value of shaving cream is 8 to 9.

o Water quality must also be checked carefully. Most

manufacturers make sure the water they use is pure by

exposing the water to ultraviolet light or using distilled water.

Having a microbiologist on site to test the water and the final

product is common in the industry.

Criteria:Criteria:

Must have well lubricant properties, skin protection

against razor.

Must have hydrating properties and softening

properties.

Should be smooth and non-dumpy.

Must be well tolerated and should be non-irritant.

Must have good wetting properties & resistance to

rapid drying.

Criteria:Criteria:

Rapid softening of beard & sufficient viscosity to

hold & should not change viscosity according to

temperature.

Easy application, easy spread.

Small quantity should produce desired lather.

Should be non-corrosive.

Must be economical.

AApplication:pplication:

We all know that shaving cream can be very useful for aiding in unwanted hair maintenance. However, it also has many excellent uses for cleaning many things around the house as well. Just check out some of these helpful uses!
