COSMETIC COMPOSITIONS

The present invention relates to new cosmetic compositions, in particular compositions for cleansing the skin or hair and compositions for conditioning the skin or hair.

Cosmetic compositions are well known, in particular surfactant based compositions for cleansing and compositions for conditioning such as hand and body moisturizers and hair conditioners. The formulations for such compositions have been improved over time so as to achieve desirable properties such as greater cleansing ability, gentleness and reduced irritancy potential. However, users of cosmetic compositions such as cleansers and conditioners of the skin and hair are increasingly looking for products that are both pleasant to use and aesthetically pleasing and that also have a novelty value.

The present invention provides, in a first aspect, a cosmetic composition which is in liquid form and is non-foamed, comprising a liquid base, one or more surfactants and gas which is dissolved and/or suspended in the liquid base.

Due to the inclusion of a gas in the non-foamed liquid product of the invention, when a container in which the cosmetic composition of the invention is provided is opened, there will be a release of gas from the liquid base into the atmosphere. For example, pressure may build up during transit that will in particular cause a release of gas from the liquid base into the atmosphere. Such a composition therefore has novelty and amusement value, due to this release of gas causing fizzing upon opening.

Accordingly, the composition comprises gas in order that gas is released upon opening of a container in which the cosmetic composition is e: :: :: ::- e ë ce ce.

A. . .. provided, for example to produce fizzing, and/or to assist foaming. The gas is not present at pressures or in amounts as would be used for conventional propellant purposes, as it is not included for this purpose.

The composition is not a composition for dispensing by aerosol as the effect of release of gas with fizzing upon opening of the container would clearly not be achieved if the composition was dispensed under the controlled pressurized dispensing of an aerosol through a valve or the like.

Accordingly, the present invention provides a non-aerosol cosmetic composition which is in liquid form and is non-foamed, comprising a liquid base, one or more surfactants and gas which is dissolved and/or suspended in the liquid base.

The compositions of the present invention include compositions for cleansing the skin or hair, such as bubble baths, bath oils, shower gels, body washes, facial washes, liquid soaps, hand washes and shampoos; and compositions for conditioning the skin or hair, such as hand, face or body moisturizers and lotions and hair conditioners.

Preferably, the composition also comprises perfume. The perfume may be one or more components that give rise to a perfumed smell. In particular the composition may suitably comprise one or more perfumes as known in the art for use in cosmetic compositions.

When the composition of the present invention comprises perfume, the release of gas that occurs upon opening of the container, as described above, propels the perfume into the atmosphere. Accordingly such a composition has the additional benefit of having an increased release of perfume upon opening of the container, as compared to an equivalent : :: :: ::.

::.. e:.: :.:.

perfumed product as presently available. Therefore, less perfume is required to achieve the same perfumed effect, for example around half the amount of perfume used in conventional products may give rise to the same effect, or the same amount of perfume will give rise to an increased sensation of perfume upon use.

The composition of the invention comprises one or more surfactant, also known as a surface-active agents Surfactants are well known in the art and may be defined as compounds that possess surface activity that, when dissolved in a liquid, in particular water, lowers the surface or interracial tension, by preferred adsorption at the liquid/vapour interfaces. Such compounds are in particular those having at least one group with an affinity for markedly polar surfaces, ensuring in most cases its dissolution in water, and a non-polar group that has little affinity for water.

The surfactant is suitably mixed in the liquid base; for example it may be suspended or dissolved in the liquid base.

The surfactant comprised in the composition may be a single surfactant or any combination of two or more surfactants. The surfactant should of course be selected such that it is cosmetically acceptable and provides the particular cosmetic composition with the desired characteristics, e.g. foaming characteristics or conditioning characteristics. The surfactant component of the composition may in particular comprise one or more of anionic surfactants, cationic surfactants, non-ionic surfactants, zwitterionic surfactants or amphoteric surfactants.

The composition may comprise surfactant at a level of from 1 to 55% by weight, preferably from 3 to 45o by weight, more preferably from 5 to 30o by weight, most preferably from 6 to 20% by weight, for example from 8 to 125'o by weight.

e fleece ce The composition suitably comprises one or more anionic surfactants.

These include fatty alcohol sulphates, fatty alcohol ether sulphates, alkyl phenol ether sulphates, alkyl aryl sulphonic acids and salts, cumene, toluene and xylene sulphonates, alkyl sulphosuccinates, alkyl sulphonates and sarcosinates. Examples of suitable anionic surfactants include sodium lauryl ether sulphate, sodium cocoyl isethionate and sodium Cl, Cat or C,6 olefin sulphonates.

In particular, the composition may comprise one or more anionic surfactants of a nature such and in amounts such that they are capable of producing noticeable foaming. The use of anionic surfactants capable of causing foaming is known in the art in conventional compositions for cleansing such as bubble baths, facial cleansers and liquid soaps, whereby surfactants are included in amounts such that upon agitation with water foam develops. Any such known anionic surfactants and known suitable quantities may be used in the compositions of the present invention.

Examples of anionic surfactants and the suitable amounts to be used for each in order to produce noticeable foaming are: fatty alcohol sulphates, fatty alcohol ether sulphates, alkyl phenol ether sulphates, alkyl aryl sulphonic acids and salts, cumene, toluene and xylene sulphonates, alkyl sulphosuccinates, alkyl sulphonates and sarcosinates, each in amounts of 1% by weight or more.

Compositions of the present invention that include one or more anionic surfactants of a nature such and in amounts such that they are capable of producing noticeable foaming are particularly advantageous. This is because when the composition is in contact with warm water, the resultant increase in temperature of the composition causes gas to be released from the composition, which then combines with the anionic surfactant, resulting in the formation of foam. Therefore whilst agitation may of )es. eqë course be carried out if desired to produce additional foam, it is not essential. Hence a clear advantage of such compositions in accordance with the present invention is the fact that foaming can be achieved without agitation of the composition.

The composition may suitably comprise one or more amphoteric surfactants. Preferably, the composition comprises one or more amphoteric surfactants together with one or more anionic surfactants.

Amphoteric surfactants as used in conjunction with anionic surfactants reduce the potential of the composition for causing skin irritation and improve foam density and longevity. Amphoteric surfactants are well known in the art and those amphoteric surfactants known for use in cosmetic compositions may be used in the compositions of the present invention. Suitable amphoteric surfactants include alkyl betaines, such as cocamidopropyl betaine, and sulphobetaines.

The composition may suitably comprise one or more cationic surfactants.

Preferably, the composition comprises one or more cationic surfactants together with one or more anionic surfactants. Such a composition having water as the liquid base may suitably be used as a hair conditioner.

Cationic surfactants are well known in the art and those cationic surfactants known for use in cosmetic compositions may be used in the compositions of the present invention. Suitable cationic surfactants include alkyl trimethyl ammonium chlorides and fatty alcohol ethoxy ammonium methyl sulphates.

The composition may suitably comprise one or more non-ionic surfactants. The composition may in particular comprise one or more non-ionic surfactants together with one or more anionic surfactants. Such a composition more preferably further comprises one or more emollients, such as vegetable or silicone oil.

e e #e ele ce e tetle In one embodiment, the surfactants and emollients in such a composition are selected in respect of their HLB (hydrophilicity lipophilicity balance) values in order that a moisturising oil/water emulsion is obtained that is suitable for use as a hand, body or face moisturizer or lotion. Non-ionic surfactants are well known in the art and those non-ionic surfactants known for use in cosmetic compositions may be used in the compositions of the present invention. Suitable non-ionic surfactants include alcohol ethoxylates, ethoxylated triglycerides and polysorbates (also known as Spans and Tweens @) and alkanolamides such as coconut diethanolamide or cocamide DEA.

The gas that is comprised in the composition of the present invention may be any gas that is cosmetically acceptable, that will not react with the other components of the composition and that is non-toxic. The gas may be a single gas, such as argon, carbon dioxide (CO2), helium, nitrous oxide (N2O) or oxygen, or a mixture of two or more gases, such as air.

Preferably a single gas is used.

The gas may suitably have a boiling point at atmospheric pressure of 0 C or less, such as -10 C or less, preferably -200C or less, more preferably -300C or less, such as -500C or less, for example -700C or less.

It is preferred that the composition comprises gas dissolved in liquid base. Accordingly, it is preferred that the gas is one that readily dissolves in the liquid base. In particular, as it is preferred that the liquid base is aqueous, it is preferable that the gas is one that readily dissolves in an aqueous solution.

It is particularly preferred that the gas is one that readily dissolves in the liquid base, for example aqueous solution, at atmospheric pressure. This eve C . . . > . t is advantageous, as the gas will then remain substantially dissolved in the liquid base when the composition is kept in a standard, non-pressurised container, rather than requiring a pressurised or other special container.

The gas is preferably one which, when dissolved in the liquid base forms a weak acid. This then acts to neutralise alkaline ingredients, including surfactants such as ethoxylated alkyl sulphates, and thus allows the composition to be maintained at an acceptable pH for cosmetic use, for example from 6 to 8, without requiring the inclusion of additional components to achieve this.

Preferably the gas is carbon dioxide or nitrous oxide, both of which readily dissolve in an aqueous solution at atmospheric pressure. Most preferably the gas is carbon dioxide, which dissolves in water to produce carbonic acid and thus can act to keep the pH of the composition at a suitable level even if alkaline components are included.

The composition may comprise gas at a level of from 0.01 to 5.0% by weight, such as from 0.1 to 3.0% by weight, preferably from 0.2 to 2.0% by weight, more preferably from 0.5 to 1.0% by weight, for example from 0. 8 to 1.0% by weight.

It is preferred that most, substantially all or all of the gas that is present in the composition is dissolved in the liquid base. For example, 70% or more of the gas that is present in the composition may be dissolved in the liquid base, preferably 80% or more, more preferably 90% or more, most preferably 95% or more, such as 98% or more, for example 99% or more.

Preferably the composition is such that when the composition is at atmospheric pressure at least some of the gas is dissolved in the liquid . be: A. I: c. . base; accordingly when the composition is exposed to the atmosphere at least some of the gas remains dissolved, suitably 5wt% or more, such as lOwto or more, for example 20wto or more.

Accordingly, it is preferred that the gas is not compressed or is substantially non-compressed.

Suitably, the gas may be at approximately ambient pressure. The gas may be at a pressure of from 100 to 150kPa, preferably from 100 to 130kPa, more preferably from 100 to 120kPa, most preferably from 100 to llOkPa, such as from 100 to 105kPa, for example from 101 to 102kPa.

The liquid base may be any cosmetically acceptable liquid base; in particular it should be a base that does not react with the other components of the composition and that is non-toxic and non-irritating to the skin. Preferably the liquid base is aqueous; more preferably the liquid base is water. The liquid base may also suitably be an oil such as a vegetable or silicone oil. The composition preferably comprises liquid base in an amount from 45 to 95% by weight, more preferably from 60 to 90% by weight, for example from 75 to 85% by weight.

The composition may further comprise one or more additional components in order to confer desired properties on the composition as required. For example, components that are conventionally used in cosmetic compositions may be included in the composition of the present invention. These include emollients, humectants, antioxidants, disinfectants, antiseptics, preservatives, including parabens, exfoliants, conditioning agents, including cationic polymers, silicones and silicone derivatives, colorants and perfumes, alone or in combination. Additional solvents for dissolving one or more of such components may also be included.

c . e ëë ace e. e.

The composition should have a viscosity such that the release of the gas from the liquid base into the atmosphere is not adversely affected.

Preferably, the composition has a viscosity of 1000 cps or less, more preferably 800 cps or less, for example 600 cps or less. In order to achieve this, components that increase the viscosity of the composition should generally be avoided where possible, for example electrolytic ingredients such as sodium chloride should be avoided in compositions comprising anionic surfactant as these components will react and increase; the viscosity of the composition. The viscosity related characteristics of standard components used in cosmetic compositions are of course well known in the art.

The present invention also provides, in a second aspect, a cosmetic product that comprises a container containing cosmetic composition in accordance with the first aspect of the invention.

Suitably the container is a sealed container so as to avoid escape of the gas from the container. Preferably the container is a re-closable container, such as a bottle or jar with a screw top or flip top lid, more preferably a re-closable container that can be resealed after each use, as this will avoid the gas escaping from the composition over a period of time between uses.

The container is preferably not an aerosol type container. The composition of the first aspect does not need to be held within a container under pressure, as the gas is not included as a propellant.

Accordingly, the present invention provides a cosmetic product that comprises a non-aerosol container containing cosmetic composition in accordance with the first aspect of the invention.

< . . < . . The container is suitably a non-pressurised container, although agitation may cause some of the gas to come out of solution, pressurizing the container to some degree. Accordingly, the container may be at a pressure of from 100 to 350kPa, such as from 100 to 300kPa, preferably from 100 to 250kPa, more preferably from 100 to 150kPa, such as from to 130kPa.

The container suitably allows release of the composition through an opening that, when opened, allows the composition to directly contact the atmosphere. In particular, the opening may be such that it allows free flow of the composition from the container. The container preferably does not have a valve or other similar release system but rather suitably allows free and direct flow of the composition out of the container through an opening.

For example, the container may be a jar or bottle with a mouth opening, which can be closed and opened by a top, lid or cap. The mouth opening is suitably such that it allows the composition to be directly poured or scooped out of the container.

A cosmetic product in accordance with the second aspect that comprises such a container is advantageous because it allows the gas in the composition to be directly released upon opening of the container, for example to produce fizzing and/or to assist in the release of perfume.

The present invention further provides, in a third aspect, a method of producing a cosmetic composition in accordance with the first aspect of the invention, which method comprises mixing one or more surfactants in a liquid base and then introducing a gas into the resultant liquid product e e ee.he eee see . until the desired amount of gas has been introduced, under conditions such that the liquid does not foam.

The conditions under which the gas is introduced are suitably such that the gas is dissolved and/or suspended in the liquid base.

If any additional components, other than one or more surfactant, a liquid base and a gas, are to be included in the composition, they may suitably be mixed with the surfactant and liquid base before the gas is introduced.

In particular, such components and one or more surfactants may be mixed together in the liquid base.

Preferably, the gas is introduced into the liquid product under pressure, for example at a pressure of 200kPa or higher, more preferably 300kPa or higher, for example 350kPa. It is also preferred that the introduction of the gas into the liquid product is carried out at room temperature or lower, in particular at 20OC or lower, preferably from -4 C to 18 C, for example from 5 to 80C.

If the gas is introduced under pressure, once the gas has been introduced, the pressure is suitably released. This may result in some gas also being released but some gas will stay in the liquid base, in particular some gas will stay dissolved in the liquid base. Accordingly, the gas in the liquid base will be at approximately ambient pressure.

Once the gas has been introduced the liquid product may suitably be returned to room temperature if the temperature was lowered during the

introduction of gas.

Preferably, the gas is introduced into the liquid product by injection, for example injection using a sinter tube. .

. . . ....DTD: e .. .- Prior to introduction of the gas, the liquid product may be de-aerated.

Any known de-aeration techniques may be used; for example nitrogen gas may passed through the liquid product in order to de-aerate the product.

Preferably, the gas is introduced such that it is not compressed or is substantially non-compressed within the liquid base.

In a fourth aspect, the present invention also provides a method for producing a cosmetic product that comprises a cosmetic composition in a container, in accordance with the second aspect of the invention, which method comprises the steps of a method in accordance with the third aspect together with a step in which the cosmetic composition or a precursor thereof is transferred into a closable container.

In one embodiment, such a method comprises the steps of a method in accordance with the third aspect, but further includes the step of transferring the liquid product comprising one or more surfactants in a liquid base into a closable container, for example a bottle, jar or other suitable packaging, before the step of introducing a gas into the liquid product.

The container is preferably a container as described above in relation to the second aspect. 1

The container is preferably non-pressurised when the liquid product is transferred into it. Preferably the liquid product is transferred into the container such that the resultant cosmetic product comprising a container containing a cosmetic composition is initially at approximately ambient pressure.

. . e C - .. ce e ë . Preferably, the liquid product as transferred comprises any additional components that are required to be present in the cosmetic composition.

The method of this embodiment is advantageous because the step in which the cosmetic composition is obtained, by the introduction of gas into the liquid product, is carried out in a closable container in which the composition can be provided for sale. Accordingly, there is no need for a step during which the cosmetic composition, which comprises dissolved and/or suspended gas, is transferred between vessels and hence the possibility of gas escaping during such a transfer is avoided.

In an alternative embodiment, such a method comprises the steps of a method in accordance with the third aspect, but further includes the step of transferring the cosmetic composition as obtained after the step of introducing a gas into the liquid product, into a closable container, for example a bottle, jar or other suitable packaging.

Preferably, the container is subsequently sealed in order to prevent the gas escaping from the composition.

The present invention will be further described by reference to the

following Example:

Example

A bubble bath with the following composition was produced: - L Component % w/w Sodium lauryl ether sulphate 5.6 Cocamidopropyl betaine 2.4 Perfume 0. 75 Carbon dioxide 0.5 Phenoxyethanol 0. 5 Methylparaben 0.1 Ethylparaben 0.1 Propylparaben 0.1 Butylparaben 0.1 Isobutylparaben 0.1 Colour qs I Water balance (to 100o) The composition was produced by mixing together all of the above components other than carbon dioxide to form a liquid product, and then cooling the product to 5 C. Carbon dioxide was then injected into the liquid product using a sinter tube, whilst maintaining the product at a temperature of 5 C and a pressure of 350kPa, until the required amount of carbon dioxide had been introduced into the product, which took approximately 45 minutes per 50 litres of composition to be produced.

The resultant composition was then transferred into bottles, which were closed using tight fitting, re-sealable lids.
