INTRODUCTION
In USPXVIII ,creams are defined as
“ semisolid emulsions of either oil in water
or water in oil type.”
“semisolid emulsions usually medicated,
intended for external application.”.
THE SKIN CARE CREAMS CAN BE
CLASSIFIED ON THE FOLLOWING BASIS:
According to emulsion type:
1. W/O creams Eg: Cold cream
2. O/W creams Eg: Vanishing cream.
According to function:
Eg - cleansing, foundation, moisturizing etc.
VANISHING CREAM
Vanishing cream gets the name from the fact that it leaves
no trace when rubbed into the skin.
These are oil in water emulsions that contains large
percentages of water and stearic acid or other
oleaginous components.
After application, the continuous phase evaporates, leaving behind a thin
residue film of the stearic acid.
IDEAL PROPERTIES OF VANISHING
CREAMS
High melting point
Pure whiteness
Very little odor and low iodine number
Rubbed easily on the skin
MAJOR INGREDIENTS USED FOR THE
PRODUCTION OF VANISHING CREAMS
Stearic acid:
Major component of vanishing cream
Good quality triple pressed must be selected
Soap formed in-situ by the reaction between
a suitable alkali and stearic acid determines hardness
of the cream.
USE : Governs the consistency of the cream
Humectants:
Glycerol most favored followed by sorbitol and propylene glycol
USE: Prevents excessive drying out of cream
Alkali
Examples are Potassium hydroxide, sodium hydroxide,
sodium carbonate,triethanolamine and borax
Potassium hydroxide is mostly used since makes a cream
of fine texture without excessive harshness.
Sodium or potassium hydroxide when used alone forms
hard cream hence used always in combination.
Borax used in combination with potassium hydroxide or
triethanolamine to form white emulsion.
Carbonates not favoured, liberates CO2 and creams become spongy.
Stearic acid provides
oil phase and 20-30%
of free acid
neutralized by alkali
Emulsifier as soap from
KOH ( IN SITU )
VANISHING
CREAM in which oil
phase melts above
body temp and
crystallizes as
invisible form to give
a non greasy and
shiny layer on skin
FORMULATION OF VANISHING CREAM
Ingredients Quantity (%w/w) Category
Oil Phase
Stearic acid,triple pressed 15.0 %
Cetyl alcohol 0.50 % Emollient, water-
absorptive, and
emulsifying properties
Isopropyl myristate 3.00 % Nongreasy emollient
Aqueous Phase
Sodium Hydroxide 0.18 % Alkali
Potassium Hydroxide 0.50 % Alkali
Glycerol 5.0 % Humectant
Water 75.82 % Vehicle
Perfume q.s. Fragrance
Preservative q.s. Antimicrobial
Ideal formula
PROCEDURE
 Dissolve the sodium hydroxide and potassium hydroxide in water, add glycerol and
preservative and heat to 80˚C.
 In another vessel, melt the stearic acid, cetyl alcohol and isopropyl myristate (oily phase) and
heat to 75˚C.
 Add the alkali solution to the melted oily phase with good agitation.
 When the mixture has cooled to about 45˚C, add the perfume and continue slow mixing
until cool.
 Cover and let it stand overnight. Remix briefly next day before packaging.
NOTE:
 The alkali reacts with some of the stearic acid to form a soap which then acts as emulsifier.
 The polyol (glycerol) prevents loss of moisture.
 Sodium sterate crystals gives pearly shine .
COLD CREAM
It is an emulsion of water in oil (w/o) type.
Used as moisturizer, makeup remover
and cleanser.
The main principle of cold cream involves slow
evaporation of water phase which leads to cooling sensation.
Cold cream is protective to the skin.
Formula contains Borax and Beeswax.
Borax soap is obtained by free acids in the beeswax and borax (sodium
borate).
The sodium soap obtained gives oil in water (o/w) emulsion.
On storage, phase inversion occurs and water in oil (w/o) emulsion cream is
formed and this is often known as cold cream.
On application, due to evaporation of water, cold sensation is observed,
hence, it is called as cold cream.
Oily film remaining on the skin gives emollient action and protection to the
skin.
IDEAL CHARACTERISTICS OF COLD
CREAM
 Should have optimum pH (4.6-6).
 Consistency should be optimum
 Should not be sticky
 Should be attractive in appearance
 Penetration through epidermis of skin should be desirable.
 Must be non-irritant and non-inflammatory.
 Should give cooling effects.
INGREDIENTS USED FOR
PREPARATION OF COLD CREAM
Normally the following ingredients are used:
Mineral oil ( liquid paraffin )
White beeswax : Thickening agent and
emulsifier (Base for the cream)
Borax: Used as emulsifier and responsible for
the whiteness of cold cream.
Alcohol, glycerin, and lanolin
Perfume: Provides Fragrance
Cold cream was traditionally based on a mixture of natural waxes and vegetable
oils (beeswax and olive oil) stabilized with borax.
At the turn of the century, mineral oil replaced the more unstable vegetable oils.
In a cold cream the proportion of fatty and oily material predominates, but
application to the skin results in a cooling effect which is produced from slow
evaporation of the water contained in the emulsion.
Replacement of part of the mineral oil with up to 15% of petroleum jelly can be
used to produce different textures and consistencies. Further substitution with fatty
acid esters such as isopropyl myristate improves the thixotropic behaviour of the
cream, thus improving its spreading properties.

Preservative q.s. Antimicrobial
Perfume q.s. Fragrance
PROCEDURE
Heat the mineral oil and beeswax in a jacketed
vessel at 75˚C and maintain heat.
In another container, dissolve borax and preservative
in water and heat to 75˚C (Aqueous phase).
Slowly add this aqueous phase to the mineral
oil-beeswax heated oily phase.
Cool to 35˚C and add perfume.
USES
For Vanishing cream
Used as adhesive for makeup powders.
Reduces loss of moisture from dry skin.
Smoothens the skin and keeps it soft.
Prevents skin from roughening and chapping.
For Cold cream
Typically used to cleanse the face off makeup
Heavily moisturises dry skin.
Can also be used as a balm for dry cracked lips.
It can also be used as a shaving cream alternative for men.
