Technical field
The invention relates to a cosmetic composition for eyes and face as a whole, to be used for waterproof and non-waterproof make-up removal, constituted of two different phases, an inferior phase, or aqueous phase, containing surfactant agents and a superior phase or oily phase.
The aqueous phase is constituted of sterile demineralized water.
A surfactant agent, which can be of the cationic, anionic, non-ionic or amphoteric type is, preferably, present in the aqueous phase. Among the non-ionic surfactant agents contained, preference is given to ethyiene oxide and propylene oxide condensates.
Among the cationic surfactant agents contained, preference is given to alkyl di¬ methyl benzyl ammonium chloride condensate.
Summary of the invention Among the emulgators
Dimethicone copolyol, glycol silicone copolymers.
These are fluids which act as artificial tension reducers, humectant agents, emulgators.
Additional benefits include emollient properties, reduction of tackiness and irri¬ tability, moisturising properties, softness and foam formation
Dimethicone copolyols are surfactants and form a mild and moisturising foam, providing a softness and smoothness sensation The aqueous phase can also contain preservative agents, buffer, sodium chlo¬ ride, and humectant and emulgator agents
Among the humectant agents is possible to name propylene glycol and glycerin
The oily phase of the composition for make-up removal, according to this inven¬ tion, is constituted of a mixture of mineral and silicone oils Among the mineral oils, is possible to name, particularly, the superior aliphatic hydrocarbonates Among the silicone oils, is possible to name cyclomethicone and dimethi¬ cone
Thus, the invention refers to a cosmetic composition for eyes and face, consti¬ tuted of a double-phase liquid, having an aqueous phase and an oily phase, in which the aqueous phase comprises approximately between 2 and 20%, by weight, of humectant, ap¬ proximately between 0,1 and 2%, by weight, of surfactant, approximately between 0,5 and 2,5%, by weight, of an emulsion inhibitor, approximately between 0,1 and 1 %, by weight, of a preservative, approximately between 0 and 1 ,0%, by weight, of emulgator and approxi¬ mately between 0,000002 and 0,0011% (approximately 0,02-11 ppm), by weight, of buffer, being the remaining to complete 100% constituted of an adequate vehicle, and in which the oily phase comprises a system constituted of approximately between 0 and 70%, by weight, of a solvent constituted of combined cyclomethicone/dimethicone or only dimethicone and between 0 to 100%, by weight, of a superior aliphatic hydrocarbonate

Action Mechanism
The cosmetic composition for eyes and face, as a whole, is used for waterproof and non-waterproof make-up removal. It loosens and removes skin make-up and impurities through solvent action, and does not cause itching The invented composition is a double-phase make-up remover, in which one phase, characterised as oily phase, exhibits chemical affinity with the raw materials usually contained in waterproof make-up This same phase also removes non-waterproof make-up
The other phase, characterised as aqueous phase, containing a low concentra¬ tion of surfactants, removes non-waterproof make-up and does not cause drying sensation
Uses and Advantages
There are waterproof and non-waterproof make-ups.
A make-up remover can act only as a non-waterproof make-up remover or both
To be effective, a make-up remover formulation acting only as non-waterproof make-up remover, can contain an high surfactants concentration.
A make-up remover formulation acting as waterproof and non-waterproof make-up types remover is, usually, based on components exhibiting chemical affinity with raw materials characterised by the fact of forming a water insoluble film (petroleum derivatives and poly- vinylpyrrolidone copolymers (PVP) and long chain alkyl olefins). The make-up remover formulations having the function of removing waterproof and non-waterproof make-ups exhibit high concentrations of raw materials which are able to remove the water insoluble film, usually oils or an high surfactants concentration
The main disadvantage of formulas containing high surfactants concentrations is their uncomfortable application, mostly causing itching, irritation and redness, dryness sen- sation after use They are not indicated for persons having dry skin.
These formula types make it particularly difficult to conciliate a good make-up removing ability and maintenance of the skin's normal conditions.
The invented make-up remover was developed to remove waterproof and non- waterproof make-up and contains components exhibiting chemical affinity with raw materials which confer the status of waterproof or non-waterproof to the make-up. It does not contain high surfactants and/or oils concentration, being a double-phase composition (oily and aqueous), extremely well balanced, indicated for all skin types.
The main advantage of this double-phase make-up remover is that one same formulation comprises an oily phase constituted of mineral oils and volatile silicone oils, not greasy, and an aqueous phase comprised of low surfactants concentration
In a research embracing the double-phase make-up remover and a market sample, following positive aspects were spontaneously reported by the users
