This document defines and describes vanishing creams. It states that vanishing creams are oil-in-water emulsions that leave an almost invisible layer on the skin after application. They contain a high percentage of water and stearic acid, which evaporates leaving a thin film. Stearic acid is the major ingredient and provides a non-greasy feel. Other common ingredients include glycerin, preservatives, and perfumes. The document provides a sample formulation and instructions for producing a basic vanishing cream.

1. Vanishing creams

2. Definition
• Greaseless creams
• Vanishing creams are oil in water type of
emulsion which when applied to skin leaves an
almost invisible layer on skin.
• Also the creams which spread easily and and
seem to disappear rapidly when rubbed on skin
are known as vanishing creams.
• These creams are made with water removable
bases/water miscible bases thus can be quikly
washed off with water.

3. • These creams are o/w emulsion contains large
percentages of water and stearic acid or other
oleaginous components
• After application to skin it continuous phase
evaporates leaving behind a thin residue film
of stearic acid.
• Stearic acid gives pearly white shine to the
skin.

4. Ideal properties
• High melting point
• Pure whiteness
• Very little odor and low iodine number
• Rubbed easily on the skin

5. Major ingredients used
• Stearic acid-
 Major componenet of vanishing creams
 High quality be used because it provides an oil phase
thus it should melt above the body temperature
 Provides non greasy film and gives very attractive appearance
to skin.
 It also provides consistency to cream
• Humectants-
 Glycerol most favoured followed by sorbitol and propylene
glycol
 Its use to prevent excessive drying out of cream.

6. • KOH or NaOH-
 Use to neutralize free fatty acid.
 NaOH makes harder creams than KOH
 Triethanol amine is also used instead which makes
preparation easy and viable in nature.
• Glycerine-
 Used to maintain consistency and enhance spreading ability.
• Perfume-
 Sandalwood ,lavender oil, l inalol, rose, geraniol.
• Water in large quantity so preservative required to
prevent microbial growth
Methyl parahydroxy benzoate (0.12%)and propyl parahydroxy
benzoate (0.12%)in combination

7. Formulation of vanishing creams
• Oily phase
 Stearic acid- 15.0%
 Cetyl alcohol- 0.5%
 Isopropyl maristate- 3.0%
• Aqueos phase
 kOH- 0.50%
 NaOH- 0.18%
 Glycerol- 5%
 Water – 75.82%
 Preservative – q.s.
 Perfume- q.s.

8. Procedure
• Dissolve the sodium and potassium hydroxide in water add
glycerol and preservative and heat to 80 degree Celsius.
• In other vessel melt the stearic acid, cetyl alcohol, and
isopropyl maristate(oily phase) and to 75 degree Celsius.
• Add alkali solution to the melted oily phase with mixing.
• When the mixture has cooled to about 45 degree Celsius, add
the perfume continue mixing until cool.
• Cover it and let it stand overnight. Remix briefly next day
before packaging.

9. Uses-
• Reduces loss of moisture from dry skin.
• Smoothens the skin and keep it soft.
• Prevent skin from roughening and chapping.
• Used as adhesive for makeup powders.
