Present invention describes oil in water emulsified cleansing composition which comprises selected natural oil, non-ionic surfactant in suitable ratios. The cleansing milk formulation requires no or minimal water for wash off and hence provides waterless cleansing.
Background of the invention
A common problem associated with the present day life style is being exposed to environmental pollution, dirt etc. The dirt that mainly comes from environmental impurities and cosmetic products deposited on skin is composed of both water and oil soluble materials. Mere washing the skin with simple water would not be sufficient to remove them. To completely remove the dirt, one needs to apply substances capable of emulsifying them into finer particles and solubilizing them in aqueous medium. For the very purpose, various cleanser formulations have been reported to handle this problem. Skin cleansers are composed of surface active substances (i.e. emulsifiers/detergents/surfactants/soaps) that lower the surface tension on the skin and remove dirt, sebum, oil from cosmetic products, microorganisms, and exfoliated corneum cells in an emulsified form. Few prior art documents provide such formulations.

Such skin cosmetic compositions cause no irritation to the skin, have great safety and affinity for the skin, exhibit excellent storage stability and emulsion stability, and present an attractive appearance. ‘657 in the examples show the essentiality of both the components in stabilizing the emulsion.
US 20050227882 provides a rinse-off cleanser compositions comprising surfactant selected from anionic, nonionic, amphoteric and cationic surfactants, titanium dioxide, optical modifier and hydrophilic structural dispersant. Said composition delivers immediate whitening effect.
An ideal cleanser should be able to remove the dirt and makeup particles by keeping the skin surface moist without damaging or irritating the skin.
Existing conventional cleansers are either surfactants and/or lathering surfactant based or soap based or based on their mixtures. Further they may be foam forming or using solvents that may not be suitable for skin. The major draw backs of the conventional cleansers are that post wash with water leaves the skin dry and require uses of skin moisturizer. In addition to that, long term uses of most of the conventional cleansers (surfactant-based or soap based) result in barrier damage, skin surface pH change and leave the skin vulnerable to different skin diseases and development of skin allergy.
Further the cleansing formulations which are natural oil based, particularly contain triglycerides and adapting them in cleansing milk formulation involves emulsification process. Emulsification of triglycerides requires large quantity of surfactants which in turn makes the final product harsh for the purpose of topical application.
Moreover, to prepare emulsified cleansing formulations are challenging because of their stability issue. One way to solve the problem of formulating a stable emulsified cleansing formulation is by using acrylates copolymers as stabilizers of the milk system. However uses of acrylates are not environment friendly as they are difficult to be removed from the skin surface and hence not desired to have such formulation.
Thus there is a need for a cleansing composition that spreads evenly on skin to gently remove dirt from the deeper layer of skin, provides stable emulsification without using undesirable acrylates.
Object of the invention
One object of the present invention is to overcome the drawback of the prior art.
It is an object of the present invention to provide an emulsified cleansing composition that is mild, gentle and spreads evenly on skin to remove dirt from the deeper layers of skin.
It is another object of the present invention to provide an emulsified cleansing composition formulated with a natural oil which employs the use of low level of surfactant and yet has excellent cleansing properties and also provides mildness.
It is yet another object of the present invention to provide an emulsified composition that provides reduced or waterless cleansing.
It is further an object of the present invention to provide a stable oil-in-water emulsified cleansing composition.
Summary of the invention
The present invention provides an oil-in-water emulsified cleansing composition comprising an oil component, non-ionic surfactant and cosmetically acceptable ingredients; wherein oil component and non-ionic surfactant is present in a ratio of 1:1 to 3:1.

The skin care cleansing composition according to the present invention comprises an oil component, nonionic emulsifier or surfactant and water. The oil component is present in an amount of 10-30 wt% while the surfactant is present in an amount of 5-30%.
The present composition is essentially water based and contains 60-90 wt% of water in the composition.
The present invention contemplates use of lower amount of surfactant in the emulsified composition wherein the ratio of oil to surfactant is in the range of 1:1 to 3:1.
The oil component of the composition consists of branched chain alcohol in an amount of 5-20% by weight and other oils in the range of 0.1-10 wt%. The presence of both “branched alcohol” and “vegetable oils” is essential for the formation of the oil-in-water emulsified cleansing composition in accordance with the present invention. The concentrations of these two types of oils have been shown to be critical in achieving the desired result as is evident from the examples.

The present invention is directed to provide a mild emulsified cleansing composition, which require less or no water for rinsing or in other words can provide waterless cleansing.
In order to make a mild product, the choice of surfactant plays a very important role. Mildness in cleansing product can be obtained by either suitable combination of anionic and non-ionic surfactant or by the combination of anionic and amphoteric surfactant. Yet another approach is the combination of anionic, amphoteric and non-ionic surfactant. However as the composition of the present invention aims to provide waterless cleansing foam generation is not desirable and use of anionic surfactants is not desirable as it produces foam in the system. Therefore the present invention contemplates the use of the non-ionic surfactant to impart mildness to the composition and helps in achieving the waterless cleansing as it does not produce any foam.
The Emulsifiers/Surfactants used in the preparation of nano-emulsions according to the present invention are non-ionic surfactants and may be selected form a group comprising: polyethylene glycol derivative of natural oils especially polyethylene glycol derivative of Ricinuscommunis (Castor) Oil, polyoxyethylene fatty acid ester of sorbitan especially polyoxyethylene sorbitan monolaurate, Polyoxyethylene glycol (40) Hydrogenated Castor Oil, Polyoxyethylene glycol (40) Sorbitan Perisostearate, Polyoxyethylene glycol (40) Stearate , Polyoxyethylene glycol (80) Glyceryl Cocoate, Polyoxyethylene glycol (120) Methyl Glucose Dioleate, Polyoxyethylene glycol (150) Distearate, Polyoxyethylene glycol (200) Hydrogenated Glyceryl Palmate, Polyglyceryl-3 Caprate, Polyglyceryl-3 Caprylate, Polyglyceryl-3 MethylglucoseDistearate, Polyglyceryl-3 Diisotearate, Polyglyceryl-3 Oleate, Polyglyceryl-4 Caprate, Polyglyceryl-4 Laurate, Polyglyceryl-4 Isostearate, Polyglyceryl-6 Isostearate, Polyglyceryl-6 Dioleate, Polyoxyethylene glycol (20) Sorbitan monolaurate, Polyoxyethylene glycol (20) Sorbitanmono stearate, Polyoxyethylene glycol (20) Sorbitan monooleate, Polyoxyethylene glycol (8) Caprylic/Capric Glycerides and combinations thereof.
