Description

PROCESS AND DEVICE FOR DEODORIZING AN ENVIRONMENT

Technical Field

The invention concerns the deodorizing, refreshing and/or fragrancing of environments.

Background

The deodorising and/or fragrancing of an environment is a well-known problem in the art. A variety of processes and devices have been disclosed and/or commercialised which attempt to solve that problem. Generally, a deodorising and/or fragrancing device is placed inside the environment to be deodorised and/or fragranced. After a while, when it is no longer active in deodorising and/or fragrancing the environment, the device is being disposed of and replaced by a fresh device. However, none of these devices known to date are satisfactory. Thus, there is a need for improvement in such devices in some or all of the following areas:

- The device should be effective even after having been exposed to wet conditions.

- The device should be effective over a wide range of temperatures.

- The device should offer a continuous and linear release of the perfume.

- The device should be refillable.

- The device should offer to the consumer flexibility in the nature and intensity of the perfume it wants the device to release. Summary of the Invention

In one embodiment, the invention is a process of deodorizing and/or fragrancing an environment which is sometimes wet and sometimes dry, such as a bathroom, a shower stall, an automatic laundry or dish washing machine, a Jacuzzi or a hot tub, where a deodorising and/or fragrancing device is placed inside said environment, said device being a container (1 ) comprising a plurality of perfumed particles (2) emitting their perfume to the outside of the container, in said environment.

The invention also encompasses such device provided with usage instructions to use it in such a specific environment. The invention also encompasses perfumed particles provided with usage instructions to use them in such a device in such an environment.

In another embodiment, the invention encompasses such a device wherein said container (1) is rigid. In another embodiment, the container (1) comprises holes (3) of different sizes and which are all smaller than the smaller particle (2) contained in said container (1). In another embodiment, the perfumed particles (2) in the container (1 ) are not all of the same size. In another embodiment, the container (1 ) contains different particles (2) comprising different perfumes. In yet another embodiment, the container (1 ) comprises perfumed particles (2) which fill between 5 % and 95 % of the inner volume of said container, preferably 20% to 80%.

Description of the figures

Figure 1 is an outside perspective view of a closed container according to the present invention.

Figure 2 is an outside perspective view of the container of figure 1 , in its opened configuration.

A container (1) is made of polyethylene, and has a length of 9 cm, a width of 5 cm, and a height of 2.5 cm. Holes (3) with a diameter of 0.15 cm are drilled in the container. The container is openable and comprises to that effect a closure (4). The inside of the container is divided in two compartments (5,5') of equal divisions. Each compartment comprises a population of perfumed particles (2) (not shown in 5).

Detailed Description of the Invention

The device according to the invention is a deodorising and/or fragrancing device. By "deodorising and/or fragrancing", it is meant that the device emits a perfume which either fragrances an environment, or deodorises it by masking malodors. The device comprises a container which contains perfumed particles emitting their perfume to the outside of the container.

The Container:

The device according to and used in the present invention comprises a container. The container can be a flexible sachet, but it is preferably a substantially rigid container, made of plastic, such as polyethylene or polypropylene. Indeed, by using a substantially rigid container, it is ensured that the perfumed particles can move freely inside the container, e.g., because of the vibrations of the washing machine, or because of the water flow in a washing machine or in a shower, maximising the surface area of the particles which is available to release the perfume, thereby improving the duration and the linearity of the release of the perfume. Also, using plastic ensures that the container is useable in wet conditions, whereas traditional deodorising devices use cardboard or paper. Also, the use of plastic ensures that the device is not deteriorated when exposed to a wide range of temperatures which can be encountered in many environments where the device can be used, such as washing machines. A device using paper or cardboard would not resist such an exposure to warm temperatures.

The container must be so as to ensure that the perfume emitted by the particles can diffuse outside. The container can therefore be made of a material which is, as such, permeable to perfumes, for instance LDPE. However, in that embodiment perfume migration through the material may be slow and more difficult to control, so that in a preferred embodiment the container is made of any plastic, and the container comprises holes which are all smaller than the smaller perfume particle contained. In an advantageous embodiment, the holes of the container are not all of the same size. Indeed, holes of different sizes may have different functions: smaller holes may have a predominant role in the release of perfume, while larger holes may be required for a quick enough drying of the device after it had been wet when used in a wet environment. Allowing the inside of the device to dry faster is desirable so as to maintain the efficiency of the device in releasing its perfume.

The container is closed in that it does not allow for particles to be released, but in a particularly advantageous execution, the container is openable and recloseable so that used particles can be disposed of and replaced by fresh particles.

The Perfumed Particles:

The particles to be put inside the container are perfumed particles which emit their perfume gradually over time. Particles suitable for use herein may be made of polymers, or clay, or porous rocks or stones such as pumice, silica or silicates.

However, particularly preferred for use herein are polymeric particles such as those which have been disclosed in W09947182, GB1 , 589,201 , US 3,505,432, US 4,247,498, US 4,156,067, and Scharfft, Modern Plastics Encyclopedia, Mc Graw-Hill Publishing Company, 1982-1983, pp 274-275, all of which are incorporated herein by reference, US 4,521 ,541 , US 4,542,162, US 5,543,398, all incorporated herein by reference.

Simply stated, the process for making such particles involves mixing a molten plastic with the perfume, and allowing the mix to solidify in the appropriate shape.

Any perfume is suitable for use herein, and suitable perfumes for use herein have been disclosed in numerous references, for example in W09947182 and US 5,540,853, incorporated herein by reference. The fragrance material within the polymer preferably has a calculated logP in the range of from about 3 up to about 8, wherein P is the partition coefficient of the active or bioactive material between n-octanol and water.

The perfume ingredients are preferred to have a boiling point of 250°C. The logP of many perfume ingredients has been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, California contains many, along with citations to the original literature. However, the logP values are most conveniently calculated by the "CLOGP" program, also available from Daylight CIS. This program also lists experimental logP values when they are available in the Pomona92 database. The "calculated logP11 (ClogP) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Volume 4, C. Hansch, P.G. Sammens, J.B. Taylor and C.A. Ramsden, editors, page 295, Pergamon Press, 1990, incorporated by reference herein). The fragment approach is based on the chemical structure of each perfume ingredient and takes into account the numbers and types of atoms, the atom connectivity and is the chemical bonding. The ClogP values, which are the most reliable and widely used estimates for this physiochemical property, are preferably used instead of the experimental logP values in the selection of perfume ingredients which are useful in the present invention.

Non-enduring perfume ingredients, which are preferably minimized in the present invention, are those having a B.P. of less than about 250°C or having a ClogP of less than about 3.0 or having both a B.P. of less than about 250°C and a ClogP of less than about 3.0. The table below gives some non-limiting examples of non-enduring perfume ingredients. The perfume compositions used in the present invention contain less than about 30 weight percent of non- enduring perfume ingredients, preferably less than about 25 weight percent of non-enduring perfume ingredients, more preferably , less than about 20 weight percent of non-enduring perfume ingredients, and even more preferably, less than about 15 weight percent of non-enduring perfume ingredients.

Examples of perfume materials which have a calculated ClogP > 3 are as set forth in the following table: Examples of Enduring Perfume Ingredients Approximate Perfume Ingredients 1 B.P.

In the preferred embodiment herein where the particles are made of plastic, it is ensured that water, whenever present, does not permeate the particles so that the perfume components present within the particles are protected until they are released. Furthermore, the use of plastic ensures that the particles are not deteriorated when the device is exposed to warm temperatures. The device is thus useable across a wide range of temperatures.

The particles herein are preferably substantially spherical, as opposed to rods or square or rectangular blocks. Indeed, when spherical, the particles have increased mobility inside the device, so that fresh and clean surfaces of the particles are exposed over time. A contrario, with restricted mobility, the same surfaces of the particles would be exposed over time, and they would become soiled and potentially clogged. Furthermore, a spherical shape - combined with the fact that the particles are preferably made of plastic, therefore hydrophobic - ensures that water droplets, when present, run off the surface of the particles, contributing to a faster drying of the particles, hence a more efficient release of the perfume after exposure to wet conditions.

Perfume loading of the particles can vary within broad ranges, depending on the particular demands for a particular device. Indeed, in a compact device, the total amount of particles may tend to be on the low side and thus the perfume loading for each particle will tend to increase, so as to compensate for the fewer particles present. Conversely, in a large device, there may be more particles and the particles will tend to carry a lighter perfume load. Particles herein typically carry between 2%-25% by weight of perfume, and the total weight of the particles may represent from 20 grams to 75 grams.

Suitable perfumed particles for use herein are commercially available from International Flavors and Fragrances (IFF) under the trade-name Polyiff.

The population of particles in a given container can be substantially homogeneous in terms of their perfume content, but it can be attractive to have a heterogeneous population. Indeed, certain particles comprising certain perfumes can be manufactured as homogeneous populations, in batches, and then the different populations can be mixed together in an infinity of variations, offering an economically attractive flexibility in the choice of perfumes and functionality. Indeed, perfumes can be used which will additionally provide sanitisation and/or antibacterial benefits. The population of particles in a given container can be substantially homogeneous in size, and that is desirable as compared to a heterogeneous population. Indeed, a homogeneous population in size ensures, for spherical particles, that there is a minimum contact surface between the particles, and surface damage and/or abrasion is reduced. Also, the risk of particles compaction is substantially reduced which would reduce the rate of perfume release, and which would impede free rotation of the particles, which in turn would impede a prolonged and gradual release of the perfume. The container may also be divided in several compartments which will each comprise a particular population of particles. The population of particles in a given compartment will preferably differ from the population in another compartment.

Preferably, the particles inside the container should fill between 5% and 95% of the inner volume of the container or each compartment, most preferably 20% to 80%. Indeed, inside those limits a best compromise is obtained between the amount of particles, which desirably should be as large as possible to increase the perfume loading of the device, and their ability to move in the container, so as to improve the duration and linearity of the release of the perfume, which at a certain point becomes hindered if too many particles are present.
