Field of the invention
The present invention relates to a skin cleansing composition, more particularly to a
skin cleansing compositionthat incorporates high amounts of Free Fatty Acids (FFA).
Background and prior arts of the invention
Cosmetic treatment involving skin cleansing is gaining much more attention in view
that skin regularly gets exposed to various agents such as UV rays, pollutants, and other
oxidative agents, which in turn act on fatty acid components of skin and makes skin
vulnerable to various dermatological ailments such as cancers, inflammation, allergy
and eczema. Washing skin with detergents such as soaps is widely followed procedure
for cleaning the surface of the skin but during this process the composition of fatty acids
of skin gets altered which leads to harsh feeling and dryness of skin. Accumulating
documented evidences suggest major disadvantages of using soap based cleansing
systems,as they are very harsh and make the skin dry, leaving white residues on skin
surface apart from altering the normal pH of the skin surface.
Prior art reported many skin cleansing soap compositions comprising of different grades
of surfactants such as anionic, cationic, non-ionic, amphoteric etc., used in
combinations. However these formulations have to be considered only after ensuring
their degree of harshness to the skin.
WO2008037609 relates to detergent compositions suitable for topical application for
cleansing and moisturizing the human skin and hair. This prior art identifies the stability
problems associated with cleansers containing combinations of substantial amounts of
hydrophobic emollients for skin conditioning, to produce good foaming and therefore
provides a cleansing composition with a foam, volumes greater than or equal to 20 ml.
This very mild and highly foaming personal cleansing composition further comprises of
0.5 to 20% by wt. of total N-(C6-C20) acyl sarcosinate surfactants; 0.5 to 50% by wt. of
total hydrocarbon or wax emollients or blends; Greater than 0.5% by wt.C10-C18 fatty

acids; 5-95% by wt water, while the ratio of the sarcosinate surfactant to the total
hydrocarbon or wax emollients is in the range of 0.04-2.0. The inventive feature of
WO2008037609 is the specific ratio in which C6-C20 acyl sarcosinates and total
hydrocarbon wax oil emollients are combined to give a liquid crystalline structure that
helps in providing good cleansing feel to the end user.
US 20060018865relates to a foaming cleansing composition which can be rinsed off
with water and has an appearance of gel. This foaming gel composition having both
good cosmetic properties (qualities of the foam and quality of rinsing) and good
properties of tolerance is provided by using surfactant system comprising at least one
alkyl glycol carboxylate and at least one surfactant of the mono/di alkyl phosphates and
their salts.
US5994280relates to foam-producing personal cleansing compositions suitable for
simultaneously cleansing and conditioning the skin and/or the hair and which may be
used, for in the form of foam bath preparations, shower products, skin cleansers, hand,
face and body cleansers, shampoos, etc. This prior art identifies the need for personal
cleansing products with abundant, stable and high quality foam generation capabilities
and at the same time providing the user good moisturizing and good rinsability
characteristics. US '280 teaches a moisturizing personal cleansing composition that
contain a total level of surfactant (inclusive of anionic, amphoteric, nonionic, betaine
and other surfactant components) from about 10% to about 35% by weight of
composition and about 0.1% to about 8% by weight of a fatty acid having an average
chain length of 10 to about 18 carbon atoms. The composition also contains about 1.5%
to about 10% by weight of citric acid or water soluble citrate salt or mixture thereof
along with water.
The above prior art compositions contains free fatty acids but is lesser amount. It is
known that free fatty acids in a soap composition impart higher moisturizing benefit. •
During skin cleansing process the composition of fatty acids of skin gets altered which
leads to harsh feeling and dryness of skin. It is desired to have a mild and /or
moisturizing skin cleansing system. One of the ways for formulating a mild skin

cleansing composition is incorporation of free fatty acid (FFA) in cleansing
formulations. Skin cleansing system having high amount of free fatty acid (FFA) is
highly accepted among the customers. Preparation of Skin cleansing system with high
amount of FFA is well known state of the art, however most of these formulation are
either soap based systems or non -soap based systems. Major disadvantage of using
soap based cleansing system is that it makes the skin dry and leaves white residue on
skin surface and also alters skin surface pH and is very harsh to use. Non-soap based
skin cleansing system has more likeability profile among customers. Foam formation is
one of the essential features of any cleansing system and it is well known state of the art
that FFA inhibitfoam formation and destabilize foam.
Hence it is required to develop a non-soap based foaming skin cleansing composition
incorporating high amount of FFA.
Object of invention
The object of the present invention is to overcome the drawbacks of the prior art.
Another object of the present invention is to provide a foaming skin cleansing
composition comprising high amount of free fatty acids.
Yet another object of the present invention is to provide skin cleansing system with a
unique combination of anionic, non-ionic and amphoteric surfactant that prevents the
destruction of foam by the activity of fatty acids in the composition.
Yet another object of the present invention is to develop a non-soap based skin
cleansing composition with high amount of FFA, which provides high and stable foam
characteristics, which would be highly preferred by the users.
A further object of the present invention is to provide a process for the preparation of
the foaming cleansing composition with high amount of FFA.
