Description

    TECHNICAL FIELD
  • The present invention relates to a product comprising a package containing an adhesive perfume delivery material and a particulate composition.
  • BACKGROUND OF THE INVENTION
  • Products such as consumer products are typically designed and/or formulated to include a perfume. The perfume of the product may improve the sensory experience of the consumer for example at the point of purchase of the product, during the use, and/or after the use of the product. To provide the consumer with a satisfying sensory experience, several perfume delivery systems have been developed. WO 07/35646 discloses a long list of these perfume delivery systems. The list includes perfume delivery systems comprising an adhesive perfume delivery material.
  • However, when using an adhesive perfume delivery material, the sensory experience of the consumer, for example when opening the package of the product, may vary. Variations of the sensory experience of the consumer are typically observed when the product comprises a particulate composition and/or when an adhesive perfume delivery material is adhered to an internal wall of the package.
  • The sensory experience of the consumer may depend on the way the product has been manufactured, shipped, or stored, or may depend on the relative position of the adhesive perfume delivery material in the package of the product.
  • For example, the sensory experience of the consumer when the particulate composition is fully or partially covering the adhesive perfume delivery material may be different from the sensory experience of the consumer when the particulate composition is not covering the adhesive perfume delivery material. This may happen if the package is opened when the product is up-side down or if the particulate composition has contacted the adhesive perfume delivery material when filling the package or when stocking the product.
  • The sensory experience of the consumer may also be different at the point of purchase of the product, during the use, and/or after the use of the product. The sensory experience of the consumer when opening the package of the product for the first time may be different from the sensory experience of the consumer when opening the package of the product for the second time.
  • The sensory experiences of the consumer may vary when the particulate composition has a different porosity, relative humidity, and/or a different density. The sensory experiences of the consumer may vary when there is a change in the chemical composition of the particulate composition.
  • The sensory experience of the consumer when opening the package of the product in a way such as the adhesive perfume delivery material is substantially covered by the particulate composition may be different from the sensory experience of the consumer when opening the package of the product in a way such as the adhesive perfume delivery material is not substantially covered by the particulate composition.
  • The sensory experience of the consumer when the product has been stored with the adhesive perfume delivery material on the upper part of the product may be different from the sensory experience of the consumer when the product has been stored with the adhesive perfume delivery material on the lower part of the product.
  • The sensory experience of the consumer may also vary from product to product. In particular, the sensory experience of the consumer opening a product 1 week after the manufacturing of the product may be different from the sensory experience of the consumer opening a product 4 months after the manufacturing of the product.
  • Such variations may result in a lack of control of the sensory experience of the consumer, a non-optimal benefit delivery to the consumer, and/or a restriction of the choices to manufacture a satisfying product.
  • Thus, there is a need for a product comprising an adhesive perfume delivery material and a particulate composition, said product alleviating the problem of the lack of control of the sensory experience of the consumer.
  • Alleviating the problem of the lack of control of the sensory experience of the consumer may mean that the sensory experience of the consumer is less dependant of parameters such as: the number of times the package of the product has been opened before the sensory experience of the consumer, the moment of the sensory experience of the consumer, the way the package of the product is opened, the features of the product, and/or the way the product is manufactured, shipped, or stored.
  • Alleviating the problem of the lack of control of the sensory experience of the consumer may mean that a better control of the rate of release of the perfume, of the intensity of the perfume, and/or of the character (the smell) of the perfume, is obtained. In particular, alleviating the problem of the lack of control of the sensory experience of the consumer may mean that a better control of the intensity of the perfume is obtained.
  • SUMMARY OF THE INVENTION
  • In one embodiment of the present invention, the invention concerns a product comprising:
      • a particulate composition,
      • an adhesive perfume delivery material,
      • a package at least partially separating the product and the adhesive perfume delivery material from the external environment
        wherein the adhesive perfume delivery material is adhered onto an internal wall of the package and wherein at least 60% by weight of the particulate composition has a particle size of above 150 μm.
  • The inventors have found that products of the invention could allow a better control of the sensory experience of the consumer.
  • The inventors have found that smaller particle cover more fully and/or in a more resilient manner the adhesive perfume delivery material such that the properties of the adhesive perfume delivery material are more affected by smaller particles.
  • The present invention also concerns the process of manufacturing a product according to the invention comprising at least the two following steps in any order:
  • a—filling of the package with the particulate composition,
    b—adhering the adhesive perfume delivery material onto an internal wall of the package,
    wherein the time lapse between step a and step b is of less than 7 days, in particular of less than 1 day, for example of less than 2 hours.
  • The inventors have found that the lack of control in the sensory experience delivered by the product that could arise when filling the particulate composition and adhering the adhesive perfume delivery material over a short period of time could be reduced when manufacturing a product according to the invention.
  • Unless otherwise specified, the percentage and ratio in the claims and the present specification are by weight.
  • DETAILED DESCRIPTION OF THE INVENTION The Product
  • The product of the invention comprises a particulate composition, an adhesive perfume delivery material and a package. The product may be in the form it is intended to be sold to the consumer. It may be intended not to submit the product to subsequent commercial manufacture or modification.
  • The product may be a consumer product in the field of baby care, beauty care, fabric & home care, family care, feminine care, health care, snack and/or beverage. In particular, the product may be a fabric-care product, for example a laundry detergent composition.
  • The Particulate Composition
  • The product of the invention comprises a particulate composition. The product may comprise from 50 to 99.99%, from 70 to 99.9%, from 85 to 99% or from 95 to 98%, by weight of particulate composition.
  • A particulate composition may be a granular or powder-form composition. Preferably the particulate composition is in free-flowing particulate form. The particulate composition may be made by any particulation or granulation process. An example of such a process is spray drying (in a co-current or counter current spray drying tower). Other suitable processes include fluid bed processes, compaction processes (e.g. roll compaction), extrusion and spheronization processes, as well as any chemical process like flocculation, crystallisation, or sintering. The particulate composition may be made by different processes, for example, part of the particulate composition may have been obtained by spray drying and another part may have been dry-added.
  • At least 60% by weight of the particulate composition has a particle size of above 150 μm. In a preferred embodiment, at least 60% by weight of the particulate composition has a particle size of above 200 μm or 250 μm or 300 μm or 400 μm or 500 μm or 700 μm. In particular, at least 70% or 80% or 90% by weight of the particulate composition has a particulate size of above 150 μm.
  • At least 90 or 95% by weight of the particulate composition may have a particle size of above 100 μm.
  • At least 60%, in particular, by weight of the particulate composition may have a particle size in the range of from 150 μm to 3000 μm. At least 50%, in particular at least 60% or 70% or 80% or 90% by weight of the particulate composition may have a particle size in the range of from 200 μm to 2000 μm, or in the range of from 250 μm to 1500 μm, or in the range of from 300 μm to 1000 μm, or in the range of from 350 μm to 800 μm.
  • Without wishing to be bound by theory, the inventors believe that when the particles of the particulate composition are in contact with the adhesive perfume delivery material, particulate composition with a broad particle size distribution tends to cover the adhesive perfume delivery material in a more air-tight way. As such, the properties of the adhesive perfume delivery material could be less affected by particulate composition having a narrower particles size distribution.
  • Preferably, the % by weight of the particulate composition which has a particle size of less than x μm size is measured by sieving. For example, the following method is used.
  • A x μm sieve is fitted on a base pan.
  • 50.0 g of the particulate composition is poured onto the calibrated sieve and the sieve is closed with a lid.
  • The sieve, the lid, and the base pan are fixed into a rotap RX-29-10 (from Gilson Company Inc) equipment.
  • The rotap is calibrated for 152 taps per minutes, 285 rpm elliptical motion.
  • The rotap is switched on for 2 minutes. The measurement is done at ambient condition, for example at 20° C. and at a relative humidity of 30%.
  • The quantity of particulate composition onto the base pan is weighted and is multiplied by 2 to obtain the % by weight of the particulate composition which has a particle size of less than x μm size.
  • The weight of particulate composition remaining on the sieve is weighted and the measurement is repeated if the weight of particulate composition onto the sieve and in the base pan is not equal to 50.0 g±0.1 g.
  • Preferably, the % by weight of the particulate composition which has a particle size of more than x μm size is measured by sieving. For example, the method defined just above is used; the weight of particulate composition remaining on the sieve and multiplied by 2 corresponds to the % by weight of the particulate composition which has a particle size of more than x μm size.
  • The particulate composition may also have a specific moisture content, expressed as a relative humidity value at 1 atmosphere and 20° C. The particulate composition of the invention may have a relative humidity value below 45%, in particular between 5% and 35% or even between 10% and 25%. Particulate composition having such a relative humidity value may allow a better control of the sensory experience of the consumer. The term “relative humidity value” as used herein relates to the relative humidity of air in the package in equilibrium with the particulate composition in the package. It is an indirect measurement of the water activity in a solid. It is the ratio of the current water concentration in the air (kg water/kg air) to the maximum at a given temperature and pressure, expressed as a percentage of the value for saturated air. For a solid an equilibrium is established between the water in the solid and the atmosphere, and the measured relative humidity is a characteristic for that solid at a given temperature and pressure.
  • The particulate composition may have a bulk density of from 300 g/l to 1,500 g/l, for example from 400 g/l to 1,200 g/l or from 500 g/l to 1,000 g/l.
  • The particulate composition may comprise at least 20%, for example at least 30% or 40%, by weight of chemical compounds which do not comprise C—H (carbon-hydrogen) bonds. The particulate composition may comprise less than 40%, or less than 20%, in particular less than 15%, or even less than 10%, by weight of surfactant. The particulate composition may comprise less than 20%, or less than 15, 10, 5 or 2%, by weight of aluminosilicate builders. Particulate composition comprising a lower level of surfactant and/or a higher level of inorganic compounds or compounds that do not comprise C—H bonds and/or a lower level of aluminosilicate builders may allow a better control of the sensory experience of the consumer.
  • The particulate composition may comprise a bleaching agent. For example the composition may comprise at least 0.1%, or at least 1, 2, 5 or 10%, by weight of bleaching agent. The product of the invention may allow a better control of the sensory experience of the consumer, even when the particulate composition comprises a bleaching agent.
  • The particulate composition may comprise a perfume. The weight ratio of the perfume comprised in the particulate composition to the perfume comprised on the adhesive perfume delivery material may be from 0.01 to 20, from 0.05 to 10, or even from 0.1 to 5 or 0.2 to 2.
  • The particulate composition may be a detergent composition in particular a laundry detergent composition.
  • The particulate composition may comprise ingredients chosen among the non-limiting list of ingredient illustrated hereinafter. The precise nature of these additional adjunct components, and levels of incorporation thereof, will depend on the physical form of the composition and the nature of the operation for which the particulate composition is to be used. Suitable ingredients include, but are not limited to, surfactants, builders, flocculating aid, chelating agents, dye transfer inhibitors, enzymes and enzyme stabilizers, catalytic materials, bleach activators, hydrogen peroxide, sources of hydrogen peroxide, preformed peracids, polymeric dispersing agents, clay soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, perfumes, structure elasticizing agents, fabric softeners, carriers, hydrotropes, processing aids, solvents and/or pigments.
