Abstract
Description
[0001] LAUNDRY PRODUCT
[0002] Field of the Invention
[0003] The present invention relates to perfumes for laundry beads.
[0004] Background of the Invention
[0005] Laundry beads or particles have become an important category of laundry products. These are particles or beads, which allow the consumer to dose additional benefit agents into the laundry process in addition to a laundry detergent or fabric conditioner. Laundry beads commonly comprise perfume, but may also comprise additional benefit agents such as anti-bacterial ingredients or softening ingredients.
[0006] Paper based packaging such as cardboard or pulp is also growing in popularity, due in part to its easy recyclability and the desire to reduce the use of plastic packaging. Paper based packaging behaves very differently to traditional plastic packaging, in particular the transmission of materials in and out of a sealed paper pack can be very different to a plastic pack. Paper packaging provides a benefit that the consumer can smell the fragrance before opening the pack this can attract the consumers attention to the product and help them make a decision on which product to buy without removing the lid of the packaging. However since laundry beads are sensitive to water, paper based packs often require a lining of some form to protect the contents from external conditions. These linings commonly restrict the egress of perfume from the packs.
[0007] Careful selection of ingredients such as perfumes is required when designing a product to be packaged in a paper-based pack with a lining to ensure the desired consumer experience is provided.
[0008] Summary of the Invention
[0009] It has been found that laundry particles comprising a perfume composition comprising 5 to 50 wt.% perfume ingredients having a vapor pressure of 24Pa (0.18 mmHg) or greater at 25°C , provide an enhanced consumer perfume experience when packaged in packaging comprising a receptacle formed from a material comprising cellulosic fibers and a barrier layer. In particular, an improved perfume experience before opening the package. Accordingly, in a first aspect of the present invention is provided a laundry product comprising laundry particles and packaging; the laundry particles comprise a perfume composition and have a maximum dimension of 1 mm to 30 mm; the packaging comprises a receptacle formed from a material comprising cellulosic fibers and a barrier layer; wherein the perfume composition comprises 5 to 50 wt.% perfume ingredients having a vapor pressure of 24Pa (0.18 mmHg) or greater at 25°C.
[0010] In a further aspect of the present invention is provided a method proving a fragrance experience to consumers before opening the lid of a package, wherein laundry particles comprising a perfume composition and having a maximum dimension of 1 mm to 30 mm are packaged in packaging comprising a receptacle formed from a material comprising cellulosic fibers and a barrier layer, and wherein the perfume composition comprises 5 to 50 wt.% perfume ingredients having a vapor pressure of 24Pa (0.18 mmHg) or greater at 25°C.

If the receptacle is a cuboid, the corners and / or edges may be rounded. The receptacle preferably comprises a child impeding closure (CIC). A CIC may be formed using ribs and ridges, requiring specific manipulation of the container or lid to separate the two parts. Alternatively, a CIC may be formed by friction fit of the container and the lid, i.e. the friction between the two parts is sufficient to impede a child’s access to the contents of the receptacle. Alternatively, a CIC may be formed by an arrangement of tabs on the container interacting with holes in the lid, whereby the user must insert their finger into a hole in the lid to release a tab on the container and allow the lid to be released. Alternatively, a CIC may be formed wherein the lid constitutes a rotatable section, which when rotated aligns with a hole in the container and creates a hole through which the contents of the container can be poured. Alternatively, a CIC may be formed by an additional fastening means, such as a clip or pin locking the container and lid together, etc. The person skilled in the art may use these or any other mechanism to impede the ability of a child to access the contents of the container.
[0051] The receptacle may be printed on using conventional inks. The printing may occur before or after the formation of the container and lid.

More preferably the barrier material is selected from polyolefins, polyvinyl alcohols, poly acetates, waxes and mixtures thereof.
[0054] As used herein, the term "polyolefin" refers to a virgin, petroleum-based polyolefin, consumer recycled polyolefin, industrial recycled polyolefin, polyolefin derived from a renewable resource (i.e., produced by a natural process at a rate comparable to its rate of consumption, such as plants, animals, fish, bacterial, fungi, and forestry products), or a mixture thereof.
[0055] Specific examples of suitable preferred barrier materials include: ethylene vinyl alcohol copolymer (EVOHs), polyethylene (PE), polyethylene terephthalate (PET), polypropolyene, polypropylene (PP), polyester, polyamides; ethylene vinyl acetate; ethylene acrylic acid; polystyrene, polycarbonate, Polyhydroxyalkanoates (PHAs) and mixtures thereof. These polymers may be produced from virgin, recycled or renewable sources.
[0056] Preferably the barrier comprises recycled material. More preferably the barrier consists of recycled material.
[0057] It may be preferable to apply a primer to the surface of the paper board before applying the barrier layer.
[0058] Laundry particles
[0059] The present invention further related to a method proving a fragrance experience to consumers before opening the lid of a package, wherein laundry particles as described herein are packaged in packaging as described herein, and wherein the perfume composition comprises 5 to 50 wt.% perfume ingredients having a vapor pressure of 24Pa (0.18 mmHg) or greater at 25°C.
[0060] The presence of the perfume ingredients having a vapor pressure of 24Pa (0.18 mmHg) or greater at 25°C provides consumers with a fragrance experience before opening the packaging.
[0061] Examples
[0062] Preparation:
[0063] Table 1: formulations
[0064] Perfume composition1- comprising 8.55 % perfume ingredient having vapor pressure of 388Pa (2.91 mmHg) and 8.55 wt.% perfume ingredient having vapor pressure 26.4Pa (0.198 mmHg), both measured at 25°C.
[0065] The laundry particles were prepared by melting the PEG, mixing in the dextrose and adding the perfume composition as the mixture cools. The mixture was pipetted onto a smooth flat surface and left to solidify, creating laundry particles. The particles were then stored in a lined and unlined pack. The packs were the same shape and size, both formed from cellulose fibers. The lined pack comprised an internal barrier layer of less than 5 wt.% polyethylene. Once filed, both packs were placed in a sealed plastic bag to contain any perfume components leaking from the pack.
[0066] Assessment method:
[0067] The perfume benefit was analysed using VOC (volatile organic compound) headspace analysis with SPME-GC-MS. The filled lined and unlined tubes were placed in Tedlar bags, sealed and equilibrated after manual shaking. The fragrance in the headspace was sampled using SPME and run using a Shimadzu QP2010 plus GC / MS instrument, under the following conditions: SPME fibre: PDMS, sampling time 10 minutes at 21°C (room temperature) GC oven: 45°C-250°C at 35°C / minute Injection: 250°C 40:1 split
[0068] GC Column: HP5 MS 20m x 0.18mm x 0.18pm film thickness Data was collected and expressed as summed GC / MS peak areas normalised for mass.
[0069] Results: Conclusion:
[0070] Ingredients having a vapor pressure above 24Pa (0.18 mmHg) at 25°C move out of a lined pack faster than they move out of an unlined pack. Inclusion of these perfume ingredients in packages with a barrier layer ensures that consumers still experience fragrance before opening the pack.
