Description

[0001] Liquid perfume complex for laundry, Perfume composition and associated manufacturing process

[0002] TECHNICAL FIELD

[0003] The present invention relates to the field of laundry care, more particularly to a liquid perfume complex for laundry, a liquid perfume composition for laundry and a method for manufacturing the complex and the composition. The present invention finds its use in laundry care to provide a perfume to fabrics during washing, drying or outside these phases.

[0004] STATE OF THE ART

[0005] Laundry care involves washing, drying, and maintaining laundry. It is common for these tasks to include scenting the laundry. Laundry care products include perfumes. Laundry care products include liquid formulations such as detergents such as scented laundry detergents and fabric softeners, as well as fabric refreshers or scented fabric fragrances that are used outside of the washing and drying phases.

[0006] The aim of scented laundry compositions is to provide a significantly higher dosage of fragrance than detergent products such as laundry detergents or fabric softeners.

[0007] These compositions generally include perfume contained in microcapsules. These microcapsules are typically melamine-formaldehyde particles that are considered microplastics. In addition, suspending agents must be used to homogenize and suspend the microcapsules. However, these components are mostly considered microplastics. Regulations on microplastics are evolving, particularly with a future ban on microplastics in detergents, planned for 2027 in France and 2029 in Europe.

[0008] Furthermore, consumers are increasingly demanding compositions with reduced ecological impacts.

[0009] Document W02023067041 is also known, describing perfumed compositions with perfume microcapsules. However, the compositions in this document exhibit instability over time, making these compositions unusable commercially. In addition, the implementation of these compositions requires an energy-intensive process that does not meet the requirements for reducing ecological impact.

[0010] There is therefore a need to offer a solution for a perfume composition for laundry with a reduced ecological impact while respecting stability and high-performance olfactory rendering objectives.

[0011] SUMMARY

[0012] To achieve this objective, according to one embodiment, a liquid perfume complex is provided comprising between 11.8% and 31.3% of free, non-encapsulated perfume, between 5.5% and 20% of microencapsulated perfume, between 27.8% and 46.7% of glycereth-17-cocoate as a solubilizer, between 25% and 38.5% of liquid cellulose as a suspending agent, the complex being free of free water, the percentages being by weight of the total weight of the four components above.

[0013] This liquid perfume complex reduces the ecological impact by using a solubilizer and a suspending agent that are not microplastics and are easily biodegradable (more than 60% is degraded after 28 days in accordance with OECD guidelines). The perfume composition provides excellent olfactory rendering on wet and dry laundry for several days or even weeks. The solubilizer allows solubilizing a high dosage of free perfume of at least 11.8% and advantageously up to 31.3%. The micro-encapsulated perfume will be released during the use of dry laundry by mechanical friction. In addition, the selected suspending agent does not require any dispersion, which allows for a more energy-efficient operating mode, nor any neutralization, which allows for a reduced number of components and advantageously without the addition of a pH adjuster.Furthermore, the suspending agent of the present invention allows the microencapsulated perfume to be suspended without increasing the viscosity of the complex or composition. This makes it possible to obtain a fluid product that does not risk forming deposits in the washing machine ducts, for example. Finally, since the complex according to the invention does not contain free water, its transport is easier. The manufacturer of laundry care products or even the consumer can add the water at the last moment.

[0014] In addition, the complex according to the invention complies on the one hand with future regulations concerning microplastics and on the other hand with objectives of stability and high-performance olfactory rendering.

[0015] In another aspect, the invention relates to a liquid perfume composition comprising the liquid perfume complex, as described above, and water. In another aspect, the invention relates to a method of making the liquid perfume complex as described above comprising mixing and stirring until homogenization of the unencapsulated free perfume with the glycereth-17-cocoate, then adding and stirring until homogenization of the microencapsulated perfume, then adding and stirring until homogenization of the liquid cellulose.

[0016] The process according to the invention has a simple operating mode requiring neither dispersion nor heating and therefore energy savings and a reduction in environmental impact. In addition, the process takes place in a single phase.

[0017] According to another aspect, the invention relates to a use of the perfuming composition as described above on wet or dry laundry after washing.

[0048] According to a first aspect, the invention relates to a liquid perfume complex for laundry.

[0049] The perfume complex is intended to be diluted in water and then applied to linen, also known as textiles.

[0050] The complex includes free perfume and microencapsulated perfume. The free perfume and the perfume contained in the microencapsulated perfume capsules may be the same or different.

[0051] For example, at least one of the fragrances among the free fragrance and the microencapsulated fragrance or both, comprises a mixture comprising dihydro-5-pentyl-2(3H)-furanone and 2,4-dimethyl-4-phenyltetrahydrofuran. According to one possibility, the mixture comprises 10-undecenoic acid ethyl ester and / or (3E)-4-(2,6,6-trimethylcyclohex-2-en-1-yl)but-3-en-2-one. The mixture as described in international publication WO2017 / 216478 is particularly suitable for the invention and in particular allows the masking of unpleasant odors. Advantageously, the mixture comprises, preferably it is made up of, dihydro-5-pentyl-2(3H)-furanone (gamma-nonalactone) at a percentage of between 20 and 80%, preferably between 20 and 75%, relative to the total weight of said mixture and 2,4-dimethyl-4-phenyltetrahydrofuran (rhubafuran) at a percentage of between 20 and 80%, preferably between 20 and 75%, relative to the total weight of said mixture.

[0052] Advantageously, the concentration of ethyl ester of 10-undecenoic acid in the mixture is between 30 and 35% relative to the total weight of said mixture and the concentration of (3E)-4-(2,6,6-trimethylcyclohex-2-en-1-yl)but-3-en-2-one in the mixture is between 30 and 35% relative to the total weight of said mixture.

[0053] Advantageously, in a particular embodiment, the mixture comprises 35% of dihydro-5-pentyl-2(3H)-furanone relative to the total weight of said mixture, 35% of 2,4-dimethyl-4-phenyltetrahydrofuran relative to the total weight of said mixture and 30% of ethyl ester of 10-undecenoic acid relative to the total weight of said mixture.

[0054] Loose perfume is a mixture of fragrance substances that are not encapsulated, unlike micro-encapsulated perfume, which is a mixture of fragrance substances placed in the heart of a capsule.

[0055] Advantageously, the unencapsulated free perfume contributes essentially to improving the perception of perfume on wet fabrics, while the microencapsulated perfume contributes essentially to improving the perception of perfume on dry fabrics. In addition, the microencapsulated perfume can be released upon handling of the dry fabric, generally under the action of mechanical forces.

[0056] Preferably, core-shell capsules, also called heart-shell capsules, are used, in which the core comprises the encapsulated perfume and is surrounded by an impermeable and frangible envelope. Preferably, the capsules are microcapsules, preferably having a size between 10 and 50 μm. For example, the shell of the microcapsule is based on a solid polymer.

[0057] Microencapsulated perfume comprises suspended dry solid capsules and water. Microencapsulated perfume is a suspension of microcapsules in water. Microencapsulated perfume advantageously comprises 30 to 50% dry solid capsules, more particularly 35 to 45% in water.

[0058] In a preferred embodiment, the microencapsulated perfume is advantageously “readily biodegradable,” meaning biodegradability greater than 60% after 28 days in accordance with OECD 301 guidelines, with further degradation thereafter. According to the OECD (Organization for Economic Co-operation and Development), the definition of a “readily biodegradable” product is established in the context of biodegradability testing, notably through specific guidelines. In this context, a product is considered readily biodegradable if it decomposes rapidly by the action of microorganisms under natural conditions, i.e. without leaving persistent or harmful residues. The OECD defines this biodegradability in relation to the rate of degradation observed within a given time period, typically 28 days, under controlled laboratory conditions.

[0059] Concretely, a product is considered "biodegradable" or "readily biodegradable" if at least 60 to 70% of the substance decomposes within 28 days of exposure to normal conditions of biological degradation, such as humidity, heat and the presence of microorganisms.

[0060] This means that, according to OECD tests, a biodegradable product should not leave toxic residues and should degrade quickly enough not to harm the environment.

[0061] Specific biodegradability tests may include methods such as:

[0062] Biodegradability test under aerobic conditions (OECD 301)

[0063] Biodegradability test under anaerobic conditions

[0064] For the avoidance of doubt, this means that if an ingredient passes one test but fails one or more others, the "biodegradability" result takes precedence over the other results.

[0065] These tests are used in particular in perfumery to determine whether a product or substance decomposes effectively in the natural environment.

[0066] Thus, the micro-encapsulated perfume is here preferably not affected by the evolution of the regulations restricting the use of microplastics in detergent products.

[0067] As a non-limiting example, the micro-encapsulated fragrance is chosen from the PlanetCaps® series, for example PlanetCaps® S 2.0 Unicom or PlanetCaps® S Serenity or PlanetCaps® S Sparkles, supplier Givaudan.

[0068] The complex according to the invention comprises from 11.8% to 31.3% of free perfume by weight of the total weight of the four components of the complex.

[0069] The complex according to the invention comprises from 5.5% to 20% of micro-encapsulated perfume by weight of the total weight of the four components of the complex.

[0070] The complex according to the invention comprises glycereth-17-cocoate as a solubilizer. Glycereth-17-cocoate is obtained from the supplier KAO under the name Levenol C-201.

[0071] Advantageously, the complex according to the invention does not comprise PEG-40 hydrogenated castor oil, nor Polysorbate-20, nor Eumulgin® VL75 (also known under the INCI name: Lauryl Glucoside (and) Polyglyceryl-2 Dipolyhydroxystearate (and) Glycerin).

[0072] The complex according to the invention comprises from 27.8% to 46.7% of glycereth-17-cocoate by weight of the total weight of the four components of the complex. The complex according to the invention comprises liquid cellulose as a suspending agent. The liquid cellulose is advantageously obtained from the supplier CP KELCO / AZELIS under the name Cellulon® R-93.

[0073] The complex according to the invention comprises from 25% to 38.5% of liquid cellulose by weight of the total weight of the four components of the complex.

[0074] The four components of the complex are free perfume, microencapsulated perfume, glycereth-17-cocoate, and liquid cellulose. The percentages of the components of the perfume complex are calculated by weight as the sum of the weight of free perfume, plus the weight of microencapsulated perfume, plus the weight of glycereth-17-cocoate, plus the weight of liquid cellulose.

[0075] Advantageously, the perfume complex does not include free water.

[0076] Glycereth-17-cocoate surprisingly makes it possible to obtain a stable and homogeneous complex in association with liquid cellulose for these dosages of free perfume and micro-encapsulated perfume, unlike the solubilizers of the state of the art which do not allow for the correct stabilization of compositions with a high perfume dosage and which are difficult to implement due to heating which is sometimes necessary.

[0077] In addition, liquid cellulose allows for a stable microcapsule suspension. Advantageously, the minimum quantity of 25%, or even 38.5% in the complex guarantees the stability of the complex and advantageously of the perfume composition, once the complex is diluted in water.

[0078] Glycereth-17-cocoate is in liquid form and can therefore be used at room temperature (RT), for example between 18°C ​​and 25°C. It does not require preheating before use, making it easier to use and reducing the ecological impact of its use, unlike other solubilizers, for example PEG-40 hydrogenated castor oil.

[0079] Furthermore, glycereth-17-cocoate is not classified as a hazardous product. Advantageously, glycereth-17-cocoate is not classified as H318 (causes serious eye damage), neither according to EC Regulation No. 1272 / 2008 nor concerning REACH registration, nor PBT or vPvB according to current EU criteria, unlike other solubilizers, for example Eumulgin® VL75.

[0080] In one aspect, the invention provides a liquid perfume complex consisting of free perfume, microencapsulated perfume, glycereth-17-cocoate, liquid cellulose.

[0081] In one aspect, the invention relates to a liquid perfume complex consisting of 11.8% to 31.3% free perfume, 5.5% to 20% microencapsulated perfume, 27.8% to 46.7% glycereth-17-cocoate, 25% to 38.5% liquid cellulose; the percentages of the components of the perfume complex are understood to be by weight of the total weight of the four components of the complex.

[0082] As a preferred example, the complex has a viscosity of 250 to 400 mPa.s or less than 500 mPa.s.

[0083] According to another aspect, the invention relates to a perfume composition comprising the perfume complex as described above and water.

[0084] According to this aspect, the perfume composition comprises 13 to 20% of perfume complex and 80 to 87% of water, by weight of the total weight of the composition. Advantageously, the perfume composition comprises at least one preservative such as, for example, phenoxyethanol or potassium sorbate or a mixture of methylizothiazolinone and benzylizothiazolinone. The preservative is added to the water and the quantity of water is adapted to the quantity of preservative added. For example, the preservative is in an amount of 0.3%, the water then being in an amount between 79.7% and 86.7%.

[0085] Advantageously, the perfume composition includes

[0086] - between 2% and 5% of free, non-encapsulated perfume,

[0087] - between 1% and 3% micro-encapsulated perfume,

[0088] - between 5 and 7% of glycereth-17-cocoate as a solubilizer,

[0089] - 5% liquid cellulose as a suspending agent,

[0090] - water, and advantageously a preservative, in an equivalent quantity to reach 100%, the percentages being by weight of the total weight of the composition.

[0091] Preferably, the perfume composition consists of

[0092] - between 3% and 5% of free, non-encapsulated perfume,

[0093] - between 2% and 3% micro-encapsulated perfume,

[0094] - between 5 and 7% of glycereth-17-cocoate as a solubilizer,

[0095] - 5% liquid cellulose as a suspending agent,

[0096] - water, and advantageously a preservative, in an equivalent quantity to reach 100%, the percentages being by weight of the total weight of the composition.

[0097] As a preferred example, the composition has a viscosity of 1 to 50 mPa.s or less than 50 mPa.s. The composition is liquid. The texture is thus light. Advantageously, the perfumed aqueous composition is sprayable, i.e. sprayable.

[0098] Advantageously, neither the complex nor the composition requires neutralization of the suspending agent. Neither the complex nor the composition includes a pH adjuster.

[0099] Advantageously, neither the complex nor the composition includes microplastic that is not readily biodegradable.

[0100] Advantageously, all components of the complex and / or composition are readily biodegradable. For the assessment of the success criteria for "readily biodegradable", the biodegradation study can be carried out using standardized methods such as OECD Method 301A, OECD Method 301B, OECD Method 301C, OECD Method 301D, OECD Method 301E, OECD Method 301F and OECD Method 310.

[0101] Free perfume and / or microencapsulated perfume include ingredients of preferably natural origin, possibly synthetic. The choice of this perfume depends on the desired odor effect and the application in which it will be integrated.
