Description

Title of the invention: Cosmetic composition for body care without added water technical field

[0001] The invention relates to a cosmetic composition for body care in the form of a gelled cleansing solution, without added water, comprising at least 90% water of plant origin, such as fruit water, floral water, or vegetable water, between 1.5% and 4% of at least one preservative, and between 0.35% and 0.45% of at least one gelling agent; more particularly, the invention relates to a no-rinse cosmetic composition for washing and personal hygiene. Prior art

[0002] Leave-in personal hygiene cosmetic products, such as dry shampoos or leave-in conditioners, have gained popularity in recent years due to their convenience and their more limited environmental impact, particularly regarding water consumption. For example, approximately 70% of the carbon footprint of a shampoo comes from the energy required to heat the water used during a shower.

[0003] Long confined to very specific uses, particularly in the hospital sector, in order to provide hygiene care to hospitalized people, for example bedridden or with reduced mobility, these products now meet a growing need for quick and easy-to-use hygiene solutions, particularly adapted to active lifestyles and situations where access to water is limited or even non-existent.

[0004] Traditionally, cosmetic personal hygiene products require water for rinsing after application, including solid products or those that need to be reconstituted in water. However, the cosmetics industry has developed innovative formulations that allow for effective body cleansing without the need for rinsing. These formulations generally include gentle cleansing agents, moisturizers, and ingredients that evaporate quickly to leave the skin clean and fresh. Some formulations may also include antimicrobial agents to ensure optimal hygiene. However, the majority of known no-rinse products are in the form of a very liquid cleansing solution, to be applied either as a spray or to washcloths, particularly in the hospital setting.

[0005] More specifically, recent innovations in the field of leave-in products have focused primarily on the hair care sector (hair care and conditioners), thus meeting consumer expectations for products that are more environmentally friendly and limit water consumption.

[0006] However, a major challenge in facilitating the widespread adoption of these products is finding a balance between cleansing effectiveness and gentleness on the skin, while avoiding the feeling of residue after use. The stability of the formulation and its ability to maintain its properties and integrity over time are also crucial aspects.

[0007] In this context, and despite recent advances in the field, consumers are still looking for improved personal hygiene products containing natural ingredients that offer effective cleansing while reducing water consumption. To date, few solutions exist for washing when access to water is unavailable or for reducing daily water consumption.

[0008] Solid or dry cosmetic products requiring reconstitution only partially address this issue. Indeed, they need to be rinsed or reconstituted with water, thus resulting in the consumption of potable water. Therefore, there are no liquid personal hygiene products that do not contain potable water (added water) in their formulation and do not require rinsing.

[0009] There is therefore a need for personal hygiene products formulated without added water, thus contributing to the conservation of water resources, which is becoming essential in France, Europe, and the rest of the world in order to meet the many major environmental challenges of our time. Indeed, the demand for drinking water will exceed the supply by 40% by 2030, according to the latest United Nations report.

[0010] To meet this need, the present invention, in an approach respecting the environment and preserving resources, relates to a cosmetic composition intended for body care and more particularly to cosmetic products of the shower gel type for cleaning and maintaining the body, without added water. Summary of the invention

[0011] Thus, the invention relates to a cosmetic composition, in the form of a gelled cleansing solution, without added water, comprising: - at least 90% water of plant origin chosen from the group consisting of fruit water, vegetable water, floral water, plant water, food water and mixtures thereof, by weight of the total weight of the composition, - between 1.5% and 4% of at least one preservative, by weight of the total weight of the composition, and - between 0.35% and 0.45% of at least one gelling agent, by weight of the total weight of the composition.

[0012] The present composition according to the invention is particularly intended for body care, including hair care, for complete cleansing of the face and body. According to another preferred embodiment, the composition according to the invention is of the leave-on type.

[0013] The invention is characterized by the use of plant-based water as the main base, replacing the added water (demineralized drinking water) traditionally present in cosmetic products, including in known no-rinse cleansing solutions, particularly those used in hospitals. This new approach makes it possible to obtain a concentrated ingredient composition while maintaining a texture suitable for no-rinse application, thus reducing the product's water footprint.

[0014] According to another preferred embodiment, the composition according to the invention comprises a specific mixture of at least three preservatives, most preferably sodium benzoate, sodium phytate, and pentylene glycol, enabling the product's integrity to be preserved despite the absence of added water, such as demineralized or purified water. Indeed, natural water of plant origin, not having the same degree of purity as demineralized, purified, or potable water, then leads to an increased risk of microbial proliferation. The inventor has thus specifically selected a mixture of three preservatives to prevent any degradation and maintain the product's integrity, including reducing the risk of oxidation.

[0015] Thus, according to a particularly preferred object of the invention, the preservatives included in the composition according to the invention are: - pentylene glycol between 1.5% and 2.5%, by weight of the total weight of the composition, - sodium benzoate between 0.2% and 0.4%, by weight of the total weight of the composition, and - sodium phytate at a maximum of 0.25%, by weight of the total weight of the composition.

[0016] According to another object, the present composition also comprises at least one gelling agent. Preferably, the gelling agent is xanthan gum at a concentration of 0.35% to 0.45% by weight of the total weight of the composition. More preferably, RHODICARE® D (OUVRICARE D) xanthan gum will be chosen, namely xanthan gum obtained from Xanthomonas campestris, in particular xanthan gum CAS No. 11138-66-2, which gives the composition according to the invention its characteristic texture, leaving in particular a fresh, pleasant, and non-sticky finish on the skin.

[0017] In a particularly preferred manner, the composition comprises between 0.35% and 0.45% of RHODICARE® D (OUVRICARE D) xanthan gum, even more specifically 0.4% (plus or minus 0.02%) of RHODICARE® D xanthan gum (OUVRICARE D), by weight of the total weight of the composition.

[0018] According to another preferred aspect of the invention, the plant-derived water, which provides beneficial properties to the formulation, in addition to its aqueous properties, is advantageously: - a fruit water, such as apple water, grape water, plum water, and / or - vegetable water such as cucumber water, and / or - a floral water such as rose water, lavender water or floral water orange, and / or - a plant-based water such as aloe vera water, coconut water, green tea water, bamboo water, and / or - a food-grade water such as rice water, oat water.

[0019] To further improve the cosmetic properties, the user experience, or the stability over time, the composition according to the invention may also include at least one antioxidant agent, and / or at least one solubilizing agent, and / or at least one perfume.

[0020] The cosmetic composition according to the present invention thus meets the various expectations of consumers while overcoming the challenges posed by cosmetic products without added water, particularly with regard to their formulations. Indeed, it overcomes the difficulties commonly encountered with formulations without added water, especially in terms of stability and texture. Thus, the cosmetic composition according to the present invention maintains optimal cleansing efficacy, has a pleasant and easy-to-apply texture, remains stable over time, and uses natural and sustainable ingredients. The present composition therefore meets modern requirements for body care, efficacy, and sustainability.

[0021] Thus, according to another aspect, the invention finds its application in the field of cosmetic personal hygiene products, advantageously for the elimination of bad odors, sebum and perspiration.

[0022] These versatile cosmetic uses thus meet the varied needs of consumers for quick personal hygiene, in particular consumers with daily body care needs but without access to a water source allowing traditional personal hygiene.

[0023] The invention therefore aims at a cosmetic use of the composition according to the invention, to eliminate bad odors, and / or sebum, and / or perspiration.

[0024] Other features and advantages will become apparent from the detailed description of the invention, the examples and figures that follow. Detailed description of the invention

[0025] Definition

[0026] For the purposes of this invention, "added water" means demineralized water, drinking water, or any other form of purified or treated water that is intentionally incorporated into a cosmetic composition as a base or carrier for a traditional cosmetic composition in aqueous or gel form. This term therefore excludes water naturally present in ingredients of plant origin such as fruit waters, vegetable waters, floral waters, or plant waters, as well as bound water or water of constitution that is an integral part of the molecular structure of certain ingredients.

[0027] For the purposes of this invention, "no-rinse" refers to a property of the cosmetic composition whereby the product is designed to be applied to the skin or hair and left in place without requiring removal by rinsing with water. No-rinse products are specifically formulated to be rapidly absorbed by the skin or hair, leaving no visible or sticky residue, and are particularly suitable for convenient and quick use in daily personal hygiene routines.

[0028] For the purposes of this invention, "RHODICARE® D xanthan gum" or "OUVRICARE D xanthan gum" refers to a xanthan gum specifically obtained from Xanthomonas campestris, notably marketed by the company PMC OUVRIE. Most preferably, said xanthan gum is the xanthan gum having CAS No. 11138-66-2.

[0029] Composition according to the invention

[0030] The present invention therefore relates to a composition in the form of a gelled cleaning solution, without added water, comprising: - at least 90% water of plant origin, by weight of the total weight of the composition, - between 1.5% and 4% of at least one preservative, by weight of the total weight of the composition, - between 0.35% and 0.45% of at least one gelling agent, by weight of the total weight of the composition.

[0031] Traditionally, cosmetic compositions, including leave-on shower gels, generally contain a significant amount of demineralized or potable water as a base. This added water acts as a carrier for the other ingredients and contributes to the texture and application of the product. However, the use of added water increases the product's environmental footprint, particularly in terms of manufacturing and transportation. For example, France sells more than 2 billion cosmetic products annually, in which potable water is the main ingredient.

[0032] The plant-based water incorporated into the composition according to the invention is thus preferably chosen from the group consisting of fruit water, vegetable water, floral water, plant water, food-grade water, and mixtures thereof. Consequently, the plant-based water is not added water such as demineralized or purified water, etc. Furthermore, this plant-based water represents at least 90% of the total weight of the composition, preferably at least 95% by weight of the total weight of the composition, which makes it possible to obtain a formulation highly concentrated in natural ingredients, reducing the water footprint and drastically decreasing the use of natural water resources, thus meeting consumer expectations.

[0033] The use of plant-based water as the main base of the composition eliminates the need for added water in the present cosmetic composition, thereby reducing its environmental footprint. Indeed, the plant-based water used in the composition according to the invention is upcycled water, meaning that the water used, derived from fruit, would have been discarded without its integration into the cosmetic formulation. This use thus provides an aqueous solution that fulfills the functions of drinking water, without depleting natural water resources.

[0034] In a preferred embodiment, the plant-based water is fruit water, more preferably apple water. Apple water advantageously provides a pleasant base for the composition according to the present invention.

[0035] However, the presence of water of plant origin, such as fruit water, can lead to undesirable effects in the context of cosmetic products, particularly body care products. Indeed, it can increase the risk of bacterial contamination and reduce product stability. It is also necessary to avoid any unpleasant sensations on the skin, such as redness, itching, or the presence of residues.

[0036] Thus, the present cosmetic composition according to the invention also includes at least one preservative and at least one gelling agent, present in specific quantities enabling the disadvantages of replacing water of vegetable origin with added water.

[0037] Thus, the composition comprises between 1.5% and 4% of at least one preservative, by weight of the total weight of the composition, and between 0.35% and 0.45% of at least one gelling agent, by weight of the total weight of the composition.

[0038] In a particularly preferred embodiment, the composition comprises a mixture of at least three specifically selected preservatives: sodium Benzoate, sodium phytate, and pentylene glycol. This specific blend effectively preserves the product's integrity despite the absence of added water, while minimizing the risk of skin irritation.

[0039] This effect is further enhanced when the proportions of these preservatives are within: - Between 1.5% and 2.5% pentylene glycol, preferably between 1.8% and 2.2%, and even more preferably 2%, by weight of the total weight of the composition, - Between 0.2% and 0.4% sodium benzoate, preferably between 0.25% and 0.35%, and even more preferably 0.3%, by weight of the total weight of the composition, - At most 0.25% sodium phytate, preferably at most 0.15%, even more preferably at most 0.1%, by weight of the total weight of the composition.

[0040] The composition according to the invention also comprises between 0.35% and 0.45% by weight of at least one gelling agent. In a particularly preferred embodiment, the gelling agent used is xanthan gum, more specifically RHODICARE® D (OUVRICARE D) xanthan gum.

[0041] The selection of xanthan gum, in particular RHODICARE® D xanthan gum (OUVRICARE D), at a concentration of 0.35-0.45%, more preferably 0.4%, gives the composition its characteristic gel texture, allowing for easy application and a pleasant feel on the skin. A pleasant feel is understood to mean, in particular, that the composition according to the invention leaves no undesirable residue after application, a fundamental property for a leave-on cosmetic body care product. Furthermore, the gel texture facilitates the application of the product without rinsing. Conversely, a form that is too liquid results in significant product loss during application and is more akin to a hydroalcoholic hand gel, unsuitable for body washing, while a form that is too thick is unpleasant to apply, leaving a sticky feeling or even considerable residue on the skin.

[0042] Thus, according to a particularly preferred embodiment, the composition comprises 0.4% of RHODICARE® D xanthan gum (OUVRICARE D), by weight of the total weight of the composition.

[0043] The composition according to the invention thus has a "gel" texture very different from existing no-rinse solutions on the market, which are often very liquid. This composition has a pleasant gel texture that leaves a non-greasy and non-sticky feeling on the skin, a particularly desirable and difficult-to-achieve characteristic for a no-rinse body care product.

[0044] Most preferably, the composition according to the invention is of the no-rinse type. The product is therefore designed to be applied to the skin and left in place without requiring removal by rinsing with water or wiping, thus meeting the expectations of consumers looking for solutions for washing anywhere, and thus overcoming the aforementioned drawbacks.

[0045] According to another object, the composition may include optional additives to improve its properties and the user experience: - at least one antioxidant agent, and / or - at least one solubilizing agent, and / or - at least one fragrance.

[0046] The addition of an antioxidant enhances the stability of the formulation and provides additional protection against oxidation. The addition of a fragrance improves the sensory experience of the product, making it more pleasant to use.

[0047] According to another aspect, the composition according to the invention can be obtained by any process known to those skilled in the art. In particular, the process for preparing the composition according to the invention may comprise the following steps: a. Preparation of the aqueous phase: i. In a clean container, pour the required quantity of plant-based water (fruit, vegetable, floral or plant water), representing at least 90% of the total weight of the composition, ii. Optionally, heat the water to a temperature between 40°C and 50°C while constantly stirring, b. Addition of the gelling agent: i. In the container, prepare a dispersion of xanthan gum in water of vegetable origin, ii. Slowly incorporate all of the xanthan gum while stirring to avoid lumps forming, iii. Continue stirring until a homogeneous, gelled texture is obtained. c. Incorporation of preservatives: i. Gradually add the pentylene glycol (between 1.5% and 2.5% of the total weight) to the aqueous phase, while maintaining agitation, ii. Next, incorporate the sodium benzoate (between 0.2% and 0.4% of the total weight), ensuring that it is completely dissolved. iii. Finally, add the sodium phytate (at most 0.25% of the total weight), continuing to stir until completely dissolved. d. Optionally, incorporate the following additives: i. Add the chosen solubilizing agent, respecting the recommended proportions. ii. Incorporate the fragrance, if applicable, ensuring an even distribution throughout the composition. e. Final homogenization: i. Continue stirring for an additional 15 to 20 minutes to ensure perfect homogeneity of the composition, f. Quality control: i. Check the pH of the composition and adjust it if necessary to ensure compatibility with skin application. ii. Control the viscosity and texture of the composition to ensure that it meets the desired specifications.

[0048] This process makes it possible to obtain the homogeneous, stable, and ready-to-use gelled composition according to the invention. It is important to note that all steps must be carried out under strict hygienic conditions to guarantee the microbiological quality of the final product.

[0049] According to another aspect, many uses of the composition according to the invention without rinsing are possible, offering a practical solution for personal hygiene in various situations.

[0050] Thus, the composition according to the invention is advantageously used: - for quick daily hygiene, for example for a quick refresh between two activities, as an alternative to a daily shower, - during sporting activities, for example for washing after a training session, for athletes traveling without access to shower facilities - during travel, for example for long journeys by plane, train or car, or in camping or hiking situations where access to water is limited - for all outdoor activities where access to water is complicated (camping, van, motorhome, bivouac) - in hospital settings, for example for the hygiene of bedridden or mobility-impaired patients, or as a quick and alternative cleaning solution for healthcare staff - during emergency situations, for example during water cuts or restrictions on water use, in disaster areas where access to running water is temporarily impossible - at outdoor events, for example at music festivals, concerts, sporting events where sanitary facilities are limited - in the event of a temporary disability, such as a broken arm or leg, making it difficult to maintain good personal hygiene - for the care of elderly or dependent people by facilitating the daily hygiene of people with reduced mobility, thus limiting the trip to a bathroom. - for intimate hygiene, as a replacement for intimate wipes, which are an environmental disaster - for occasional cleaning of children aged 3 and over - for the tourism industry facing the need to limit water consumption, such as campsites, but also guesthouses, mountain huts, youth hostels...

[0051] These numerous uses demonstrate the versatility and appeal of such a personal care product, thus generally meeting a need for personal hygiene in a context where access to water or time to access it is limited.

[0052] According to another object, the composition according to the invention has several beneficial effects, namely: - Eliminating bad odors: The formula helps neutralize unwanted body odors, and / or - Elimination or reduction of impurities: sebum, perspiration, all bodily secretions. The formula thus helps regulate sebum production, contributing to clearer skin.

[0053] The invention is now illustrated by non-limiting examples of compositions according to the invention and by results. Examples
