The present disclosure relates to a composition for cleaning, in particular for cleansing of the skin and/or mucous membranes, in particular a personal care cleansing composition, to be applied onto tissue paper, in particular toilet paper. The present disclosure also relates to the use of said composition.
Improving personal care hygiene, when using the bathroom, is a constant need. Regular and effective cleaning not only improves the level of cleanliness but may also prevent irritation and/or, in some cases, prevent occurrence of infections and/or promote healing of disorders. Thorough cleanliness of the desired surface can be obtained by the conventional water/soap/drying routine. However, when travelling or working away from home, such method is not very convenient.
An alternative is the use of wet wipes or wet folded toilet paper under the faucet. However, these methods are not necessarily the most effective: plain water tears the toilet paper often making it unusable and wet wipes must be kept moist and hence may require specific packaging. Moreover, the waste created with soiled wet wipes, cannot be flushed like toilet paper as they do not disintegrate rapidly in water and can clog the pipes.
It is thus highly desirable to improve personal care hygiene when using bathroom, by ensuring thorough cleanliness of the desired body surface by eliminating the need of the above-mentioned methods.
Foamable cleansing compositions are good alternatives to previously mentioned methods. Such compositions have already been described in DE 10 2009 013 268. A foamable cleansing composition, Aaah® commercialized by Aaah Company, is currently on the market. This composition essentially contains water, a foamable surfactant, an emollient, a soothing agent, a deodorant and natural extracts. Despite their improvements over the previously mentioned methods, these foamable compositions have some drawbacks. The main drawback of these compositions is the insufficient stability of the foam over time once applied onto the tissue paper, causing a too quick absorption of the foam by the paper, and hence a too quick “soak through” and tear of the paper by the foam.
The term “soak through paper properties” refers to the ability of the composition to soak, penetrate, diffuse and pass/go through the sheets/layers of the tissue paper piled on each other. The faster a composition soaks, penetrates, diffuses and passes/goes through the sheets of tissue paper, the faster it can tear said sheets, making them unusable.
Therefore, a need currently exists for a composition for cleansing of the skin and/or mucous membranes, which:
has improved soak through paper properties (does not soak through the paper),
has an effective cleansing action,
does not need to be rinsed, and
leaves a clean, soothing and pleasant feel.
More particularly, a need exists for a composition for cleansing of the skin and/or mucous membranes, which, once applied onto the tissue paper, more particularly toilet paper, is capable of remaining on the surface of the paper in the form of a foam and not soak through the paper during use, thereby allowing efficient cleansing.
In addition, a need exists for a cleansing composition as indicated above that is environmentally-friendly, without extra waste, easy to handle and that does not require costly ingredients.
Furthermore, a need exists for a composition for cleansing of the skin and/or mucous membranes, that is capable of producing high quality foam (high stability over time and good soak through paper properties), with a very good cleansing action, good skin tolerance and skin care action, and without needing to be rinsed.
In a first embodiment, the present disclosure addresses these and other needs in the art by providing a composition including:
at least 70% by weight of water, relative to the total weight of the composition;
0.1 to 1% by weight of at least one gelling agent, relative to the total weight of the composition, and
0.1 to 10% by weight, of at least one surfactant including at least one foaming surfactant, relative to the total weight of the composition.
In particular embodiments, the composition satisfies at least one of the following conditions:
once transformed into foam and applied onto the surface of several sheets of tissue paper placed one on top of each other, the time required for said composition to soak through said sheets of paper, with or without applied pressure, is at least two times greater than the time required for a composition without a gelling agent (i.e. comparative examples 1 and 2) to soak through said sheets of paper, and/or
the foam stability of said composition is such that after two minutes, the said composition is transformed into liquid at least two times less fast than a composition without a gelling agent (i.e. comparative examples 1 and 2), and/or
once transformed into foam and applied onto the surface of several sheets of tissue paper, the time required to tear said sheets of paper under a mechanical stress, is at least two times less than the time required to tear said sheets of paper onto which a composition without a gelling agent (i.e. comparative examples 1 and 2) is applied.
In an alternative embodiment, the present disclosure addresses the above-mentioned and other needs in the art by providing a composition including water, at least one gelling agent and at least one surfactant including at least one foaming surfactant, wherein said composition satisfies at least one of the following conditions:
once transformed into foam and applied onto the surface of several sheets of tissue paper placed one on top of each other, the time required for said composition to soak through said sheets of paper, with or without applied pressure, is at least two times greater than the time required for a composition without a gelling agent (i.e. comparative examples 1 and 2) to soak through said sheets of paper, and/or
the foam stability of said composition is such that after two minutes, the said composition is transformed into liquid at least two times less faster than a composition without a gelling agent (i.e. comparative examples 1 and 2), and/or
once transformed into foam and applied onto the surface of several sheets of tissue paper, the time required to tear said sheets of tissue paper under a mechanical stress, is at least two times less than the time required to tear said sheets of paper onto which a composition without a gelling agent (i.e. comparative examples 1 and 2) is applied.
In the alternative embodiment, the composition includes:
at least 70% by weight of water, relative to the total weight of the composition, and/or
0.1 to 1% by weight of at least one gelling agent, relative to the total weight of the composition, and/or
0.1 to 10% by weight of at least one surfactant including at least one foaming surfactant, relative to the total weight of the composition.
All features and aspects disclosed in greater detail hereafter, apply to both of the aforementioned embodiments.
In a particular embodiment, the above-mentioned tissue paper is a 1-ply CWP (conventional wet-pressed)+1-ply TAD (through-air-dried) toilet paper weighing 38.5 g/m2.
Once the composition is transformed into foam and applied onto the surface of 2 sheets of tissue paper placed one on top of each other, for example 2 sheets of a 1-ply CWP+1-ply TAD toilet paper weighing 38.5 g/m2, the time required for said composition to soak through said sheets of paper without applied pressure, is at least two times greater than the time required for a composition without a gelling agent (i.e. comparative examples 1 and 2) to soak through said sheets of paper.
Once the composition is transformed into foam and applied onto the surface of 4 sheets of tissue paper placed one on top of each other, for example 4 sheets of a 1-ply CWP+1-ply TAD toilet paper weighing 38.5 g/m2, the time required for said composition to soak through said sheets of paper with applied pressure, is at least two times greater than the time required for a composition without a gelling agent (i.e. comparative examples 1 and 2) to soak through said sheets of paper.
Once the composition is transformed into foam and applied onto the surface of 3 sheets of tissue paper placed one on top of each other, for example 3 sheets of a 1-ply CWP+1-ply TAD toilet paper weighing 38.5 g/m2, the time required to tear said sheets of paper under mechanical stress, is at least two times less than the time required to tear said sheets of paper onto which a composition without a gelling agent (i.e. comparative examples 1 and 2) is applied.
In certain embodiments, the cleansing composition is for topical application, meaning an external application to the skin and/or mucous membranes. Since the composition is for topical application, it includes a physiologically acceptable medium. The term “physiologically acceptable medium” is intended to mean a medium compatible with the skin and/or mucous membranes.
In certain embodiments, the composition is foamable, meaning that when combined with a gas, such as air, it is capable of being transformed into a foam.
The composition brings effective cleanliness with small amounts of surfactant(s) and leaves a fresh and pleasant feel to the skin and improves the softness of the tissue paper on which it is applied. Furthermore, no rinsing is required with the composition.
The composition includes at least 70% by weight, or 80% by weight of water, relative to the total weight of the composition. The amount of water can range, for example, from 70% to 95% by weight, from 80% to 95% by weight, or from 85% to 95% by weight, relative to the total weight of the composition, including the stated values and all weights and weight ranges between stated values.
The composition may optionally contain, in addition to water, one or more solvents chosen from alcohols containing from 1 to 6 carbon atoms such as ethanol; polyols such as glycerol; glycols such as butylene glycol, sorbitol, isoprene glycol, propylene glycol, polyethylene glycols such as PEG-8. The amount of solvents used in the composition, in addition to water, can range from 0.5 to 20% by weight and or from 1 to 10% by weight, relative to the total weight of the composition, including the stated values and all weights and weight ranges between stated values.
The term gelling agent, also known as thickening agent, is intended to mean a polymer which swells in water and increases the viscosity of the composition, gives a better feeling, decreases the foaming properties of the composition, etc. The stability of the composition before and after being transformed into foam, is also improved by the presence of the gelling agent.
In particular embodiments, the gelling agent can in particular be chosen from:
acrylic polymers chosen from
Clays such as montmorillonites, hectorites, bentonites, beidellites and saponites, are modified by chemical compounds selected from quaternary/tertiary amines, aminoacetates, imidazolines, amine soaps, fatty sulfates, alkyl aryl sulfonates, amine oxides, and mixtures thereof, in order to make them capable of swelling in oily media.
In a certain embodiment, the gelling agent is chosen from:
acrylic polymers chosen from acrylic and/or methacrylic acid homo- or co-polymers, their salts and esters, acrylic acid and acrylamide copolymers, acrylates/C10-30alkyl acrylates copolymers, polyacrylamidomethyl propane sulfonic acid and its derivatives, carbomers, in more certain embodiments, carbomers,
cellulose derivatives selected from hydroxypropylcellulose, hydroxyethylcellulose, ethylhydroxyethyl cellulose, methylcellulose, hydroxypropyl methylcellulose, carboxymethyl cellulose, or quaternized derivatives of cellulose, in more certain embodiments, hydroxythylcellulose (HEC); and mixtures thereof.
In a still more certain embodiment, the gelling agent(s) is (are) chosen from carbomers, hydroxythylcellulose (HEC), and mixtures thereof.
When a composition is foamable, it is usually difficult to thicken the foaming medium while at the same time conserving the required properties, i.e. ability to foam in particular with a foam dispenser; good foam stability and reduced “soak through paper” properties when applied on tissue paper, in particular toilet paper. Hence, the choice of the gelling agent and the amount used in the composition of the invention is an important parameter. A cleansing composition including less than 0.1% by weight of gelling agent shows a too low “soak through properties” and foam stability. A cleansing composition including more than 1% by weight of gelling agent shows a too high viscosity and thus difficulty in transforming the composition into foam, in particular with a foam dispenser.
In a particular embodiment, the total amount of gelling agent(s) in the composition is from 0.2 to 0.5% by weight, or from 0.25 to 0.45%, by weight, relative to the total weight of the composition, including the stated values and all weights and weight ranges between stated values. The “total amount” is intended to mean the amount of all gelling agents(s) present in the composition.
As already indicated, the composition includes at least one surfactant including at least one foaming surfactant. This means that the composition may either contain only one or more foaming surfactant(s), or one or more other type(s) of surfactant(s) in addition to the foaming surfactant(s).
The term “foaming surfactant” is intended to mean a surfactant which has foaming properties when it is introduced in water.
The foaming surfactant(s) may be chosen from, but not limited to, the following surfactants:
amphoteric surfactants chosen from
non-ionic surfactants chosen from
In a particular embodiment, the composition includes at least one foaming surfactant, said foaming surfactant(s) being a betaine derivative chosen from alkylbetaines such as cocobetaine, alkylaminobetaines (alkyl amidobetaines) such as cocamidopropylbetaine, and mixtures thereof.
The total weight of foaming surfactant(s) in the composition ranges from 0.1 to 10% by weight, or from 0.5 to 6% by weight, relative to the total weight of the composition, including the stated values and all weights and weight ranges between stated values. The “total weight” in this embodiment is intended to mean the weight of all foaming surfactants present in the composition.
As previously mentioned, the composition may only contain foaming surfactant(s). The composition may further contain or one or more other surfactant(s) in addition to the foaming surfactant(s). The total weight of surfactant(s) including the foaming surfactant(s) in the composition, ranges from 0.1 to 10% by weight, or from 0.5 to 6% by weight, relative to the total weight of the composition, including the stated values and all weights and weight ranges between stated values. The “total weight” is intended to mean the weight of all surfactants present in the composition.
The additional surfactants are mainly intended to lower the surface tension of water and other liquids or that between a liquid and a solid. They may thus act, for example, as detergents, wetting agents, emulsifiers and dispersants. They may also have foaming properties.
The additional surfactant(s) may be chosen from:
anionic surfactants chosen from
cationic surfactants chosen from quaternary ammoniums, alkylpyridinium chlorides, alkylammonium saccharinates, or aminoxydes having a pH<6.5;
and mixtures thereof.
The composition may contain further additives and/or active agents chosen from, for example:
and mixtures thereof.
The amounts of these various additives are those conventionally used in this field, and complete the weight of the composition to a total weight of 100%. These additives and the concentrations thereof should be such that they do not modify the property desired for the composition and that they do not destabilize it.
In a particular embodiment, the composition contains at least a soothing agent or emollient. The soothing agents or emollients can be chosen from panthenol; polyols such as glycerol or glycerin; glycols such as butylene glycol, and mixtures thereof.
The amount of emollients in the composition ranges, for example, from 0.1 to 5% by weight relative to the total weight of the composition, including the stated values and all weights and weight ranges between stated values.
According to a particular embodiment, the composition includes:
88 to 92% by weight of water,
0.25 to 0.45% by weight of a gelling such as carbomer and/or hydroxyethylcellulose,
1.5 to 2.5% by weight of a foaming surfactant such as cocamidopropylbetaine,
0.2 to 2.5% by weight of emollients such as butylene glycol and/or panthenol,
0.1 to 1% by weight of preservatives such as caprylyl glycol and/or phenoxyethanol,
0.5 to 1.5% by weight of a natural extract such as aloe vera,
0.15 to 2.7% by weight of a pH modifier such as sodium hydroxide or citric acid,
0.1 to 0.15% by weight of a chelating agent such as EDTA,
0.1 to 0.2% by weight of a fragrance such as Fleur d'ea MIP 1101016,
all weights being relative to the total weight of the composition.
In certain embodiments, the composition is in the form of a gel.
In certain embodiments, the composition has a viscosity ranging, for example, from 0.001 to 1 Pa·s, measured at a temperature of 25° C., using a Brookfield LV DV I+ from BROOKFIELD ENGINEERING LABORATORIES, INC. In particular embodiments, the viscosity of the composition ranges from 0.001 to 0.500 Pa·s, or from 0.010 to 0.350 Pa·s. The viscosity measuring device is equipped with a set of four spindles: LV1, LV2, LV3 and LV4. The following spindles (sp) and rotational speeds (v) are used:
The composition is foamable meaning that it is specifically formulated to form a foam when aerated. Said foam may be formed by using, for example, a foam dispenser.
In particular embodiments, the foam dispenser is easy to use, forms foam instantly, in a precise dosage, allows an improved spread of effective ingredients, and without use of propellants.
The composition may be contained in a dispensing foam pump container using, for example, a positive displacement pump that acts directly on the composition. The pump draws the composition up a siphon tube from the bottom of the container, and the composition is forced out a nozzle.
For example, the dispensing foam pump container may be an aerosol container. In an aerosol container, the composition is maintained under pressure sufficient to cause foam formation when dispensed. Of particular advantage, however, the composition is foamable without necessity of being placed in an aerosol container.
Airspray pump foamers allowing precise mixing of the composition and air without using gas propellants, can be used. Their use results in a high quality foam with each single stroke.
Foam dispensers may be chosen from F2-L11, F3-L11, G3-L11, WRT4-L11, WRT-L11, F2-L9, F3-L9, G3-L9, T1-L9, WRT4-L9, WRT-L9, F2-L7, F3-L7, G3-L7, T1-L7, WRT4-L7, or WRT-L7 sold by Rexam. Other foam dispensers supplied by other suppliers may also be used.
Automatic touchless foam dispensers may also be used. An example of such automatic touchless foam dispenser is: enMotion® Automated Touchless Soap Dispenser.
Said foamer dispensers entrain air in the composition as it is dispensed.
Also described herein is the use of the composition for cleansing of the skin and/or mucous membrane.
Additionally, the composition can be used with tissue paper, in particular toilet paper, for cleansing of the skin and/or mucous membrane.
Also described herein is a method for cleansing skin and/or mucous membrane including:
(i) applying the composition to a tissue paper, in particular toilet paper, and
(ii) cleansing the areas in need of being cleansed.
In step (i), when applied onto the tissue paper, the composition is in the form of a foam. The cleansing step (ii) may be carried out by wiping the areas to be cleansed with the tissue paper including said foamed composition on its surface.
The present disclosure also relates to a method for cleansing skin and/or mucous membrane wherein the composition is
(i) applied directly on the areas to be cleansed, and
(ii) cleansing said areas by wiping with a tissue paper, in particular toilet paper.
The cleaning composition may be applied onto all types of tissue papers such as hankies, facial tissues, tissue wipes, hand towels, kitchen towels, for cleaning any type of supports, and in particular for cleansing the skin or the mucous membranes. In a particular embodiment, the tissue paper is toilet paper. In a more particular embodiment, the tissue paper, in particular toilet paper, does not contain a wet strength agent.
The composition may also be applied directly on the skin and/or mucous membrane to be cleansed, and then rinsed off with water. However, this is not a preferred embodiment of the present invention.
The present disclosure further concerns a kit for cleansing of the skin and/or mucous membranes including the composition and a dispensing foam pump container. Said kit may further include tissue paper, in particular toilet paper.
The present disclosure also concerns a container provided with a dispensing foam pump and containing a composition.

Aaah® composition differs from compositions nos. 56 to 59 essentially by the absence of gelling agent, pH modifier, chelating agent and perfume.
Products nos. 56 to 59 (according to embodiments of the invention) were tested and compared to product no. 3 and commercialized Aaah® product.
Each composition was transformed into a foam by a foaming pump dispenser, reference F2-L11 manufactured by the company Rexam, and applied on sheets of toilet paper.
Several toilet papers were tested:
Lotus Confort: 1-ply CWP+1-ply TAD (100% virgin fibers); weight 38.5 g/m2
Auchan 2-ply; 2-ply CWP (100% virgin fibers); weight 38.5 g/m2
Lotus Professional Next Turn Compact 2-ply CWP (100% recycled fibers); weight 30 g/m2
Moltonel; 3-ply CWP (100% virgin fibers); weight 54 g/m2
Several methods have been used to compare the effectiveness of different foams.
Method 1: Measure of the Time Required for the Composition to Soak Through Toilet Paper without Applied Pressure
The sensor shown in
Several sheets (i.e. 2 or 6 sheets) of toilet paper (4) were placed on the printed circuit and maintained by a plastic plate (5) with a hole (6) so that they remain flat against the printed circuit. This is shown in
The method is repeated identically for each product and each toilet paper. The following results are obtained (average of 5 measurements).
These results show that the time required for the compositions according to embodiments of the invention, which contain a gelling agent, to soak through two superposed sheets of the different toilet papers used, is more than two times greater than compositions no. 3 and Aaah® which do not contain any gelling agent. The improved “soak though” property (soak through speed is reduced) of the compositions according to embodiments of the invention is thus due to the presence of a gelling agent.
Method 2: Measure of the Time Required for the Composition to Soak Through Toilet Paper with Applied Pressure
A pile of toilet paper is prepared by superposing several sheets (i.e. 4, 6 or 8 sheets) one on another. This pile is placed on the printed circuit. A dose of foam is sprayed onto the top sheet at a distance of between 30 and 60 mm, with an angle of between 45 and 90° from the vertical. At the same time, a chronometer is started. A plastic plate weighing 194 g with a surface area of 81 cm2 is placed on the foam as quickly as possible. As soon as the lamp is lit, the chronometer is stopped and the time required for the fluid to soak through the four sheets is noted.
The following results are obtained (average of 5 measurements).
From the results obtained, it appears clearly that the time required for the compositions according to embodiments of the invention, which contain a gelling agent, to soak through four superposed sheets of the different toilet papers used, even when pressure is applied, is more than two times greater than compositions no. 3 and Aaah® which do not contain any gelling agent. These results show the improved “soak through” property (soak through speed is reduced) of the compositions according to embodiments of the invention due to the presence of the gelling agent.
The amount of foam transformed back into liquid over time shows the stability of a composition. The stability of compositions nos. 56 to 59 (according to embodiments of the invention) was measured and compared to the stability of compositions no. 3 and Aaah®, using the equipment illustrated in
Based on the results illustrated in
Based on these results, it is clear that the presence of a gelling agent improves the stability of the compositions.
Method 4: Measure of the Time Required for the Tissue Paper onto which the Foam is Applied to Tear Under a Mechanical Stress (Strength of the Paper)
Several sheets (i.e. 2 or 3 sheets) of toilet paper (4) are fixed on a 53 mm diameter cylindrical container (13) with a rubber band (not represented) so as to have an evenly distributed voltage. A dose of foam (8) is sprayed onto the top sheet at a distance of between 30 and 60 mm, with an angle of between 45 and 90° from the vertical. A cylindrical weight (12) having a diameter of 20 mm, a height of 21.5 mm and a weight of 50 g, is placed on the sheet. This is illustrated in
The following results are obtained (average of 5 measurements).
It appears from these results that under mechanical stress, the time required for superposed sheets of the toilet paper onto which the foam is applied, to tear, is more than two times less than the time required for superposed sheets of the toilet paper onto which comparative compositions (no. 3 and Aaah®) without a gelling agent are applied, to tear.
Compositions nos. 55 and 60 according to embodiments of the invention were prepared in a conventional manner, for example, by simple admixture of components at room temperature (20° C.+5° C.), and tested.
The amount of each component of the composition is given in % by weight relative to the total weight of the composition. The pH of the different compositions is 5.7+0.2.

The viscosity of each composition is measured at a temperature of 25° C., using a Brookfield LV DV I+ from BROOKFIELD ENGINEERING LABORATORIES, INC, as indicated previously.
Composition no. 55 showed a higher viscosity than composition no. 56, which may render the pumping slightly more difficult. The stability of this composition is lower than that of composition no. 56 but higher than the stability of comparative examples 1 and 2.
Composition no. 60 showed a lower viscosity than composition no. 57. Its soak through properties are not as good as composition no. 57 but still remain satisfactory.
