Abstract
Description
A Fragrance TabletAREA OF INVENTION
[0001] The present invention refers to the area of fragrances and discloses a fragrance tablet for application in personal care.BACKGROUND OF THE INVENTION
[0002] The 21st century is also referred to as the hedonistic age, in which both sexes attach great importance to physical appearance. This refers not only to the preferred clothing, but also to wearing the right fragrance for every occasion, in order to underline the desired impression on the other person. As different as these occasions are, so different are the fragrances that are to convey a message. In the morning, at the start of the working day, it may be a youthful, fresh fragrance, in the afternoon a sporty note, while in the evening it may also be a heavy perfume. Of course, consumers can accommodate this desire by having several fragrances at his or her disposal, depending on the occasion.
[0003] However, the fragrance palette of perfumers seems to be inexhaustible. New creations are constantly entering the market, replacing less successful products or seeking their own niche. But the vast selection makes it difficult for consumers to make a choice. Perfumes are often luxury products, of which only a small number are usually kept at home. Buying new, perhaps still unknown products, which at the end of the day are not to one's liking and are sooner or later discarded, is a costly affair and not sustainable.
[0004] The market has therefore long been interested in being able to sell the consumer several fragrances at the same time as making a single purchase decision. So far, this has been solved with ensembles of various well-known fragrances, which are bottled in miniatures of the original flacons and then sold together. This solution is naturally very complex and expensive, and has not become established in the market. Equally well known is the addition of various perfumes in inconspicuous spray containers with a few milliliters of content, which perfumeries add to their customers as "samples" when they purchase other items. However, this only serves to arouse interest.
[0005] Therefore, there is still a need in the market for new delivery forms of fragrances that have a highly individualized character and, above all, make it possible, to select the most suitable one for the specific occasion from a wide range of perfumes, without having to stock a large number of different fragrances for this purpose.
[0006] A further problem of perfumes and fragrances is their stability as well as their solubility. Thus, fragrance compositions in general contain ethanol which contributes to the solubility and thus also to the stability of fragrance raw materials. However, if ethanol is usedtoo often on human skin, it destroys the skin's own substances that keep it healthy. In addition, alcohol has an astringent effect and can dry out the skin. Thus, there is a need in the market for fragrance compositions that are free of ethanol.RELEVANT PRIOR ART
[0007] WO 1993 008255 Al (HENKEL) refers to tablets destined above all for textile washing and rinsing baths, where sorbite is used as a carrier and carbonate and acid are used as a gas evolving system. These tablets may contain large amounts of scent, are storage stable, but disintegrate very quickly in water
[0008] US 4,196,851 Al (TREASURE MASTERS) claims a porous sachet tablet prepared by compression molding or tableting a powder composed of insoluble tri-basic calcium phosphate mixed with a minor amount of soluble sodium hexametaphosphate and bonded with a small amount of food starch and internally lubricated with a fatty acid soap, preferably magnesium stearate, to aid tableting. This tablet or blank is preferably prepared by slurrying the phosphates and the binder in water, spray drying the slurry, dry-mixing in the lubricant and compression molding. The tablet is then wetted with a perfume of the desired fragrance to give the sachet tablet.
[0009] US 2005 049154 AA (BRADY) discloses a fragrance formulation that uses effervescing agents to emit a fragrance from a non-splashing cone-shaped delivery tablet.
[0010] US 2010 0166816 AA (ZOBELE) refers to a tablet for retaining a volatile substance in a liquid or solid state, such as a perfume and / or an insecticide. The tablet comprises at least a first and a second layers of volatile substance retaining material, said first and second layers being spaced apart from each other at a selected distance, and wherein it further comprises a layer of impermeable material joined to said layers and located in between said first and second layers.
[0011] US 2013 165366 Al (SLABODEN) refers to a fragrance tablet having a fragrance selected from the group consisting of synthetic fragrances, natural fragrances and essential oils; and a fragrance tablet delivery device, wherein said fragrance tablet delivery device is water soluble and related method is disclosed. The fragrance tablet dissolves in wash water and mixes with non-fragranced laundry detergent to create a desired scent.
[0012] CN115779126 A (GUANGZHOUXUELEI) provides a long-acting perfumed tablet and a preparation method thereof, comprising a substrate and a perfume liquid; wherein the spice liquid comprises the following raw materials: absolute ethyl alcohol, glycerol, a sweet- scented osmanthus extract, a turmeric extract, a murraya paniculata extract, sodium alginate, a surfactantjojoba oil, essential oil and water.OBJECT OF THE INVENTION
[0013] Therefore, it has been the problem underlying the present invention to provide fragrance compositions in a new dosage form which permits the individual production of a perfume for single use. The aim was to design the dosage form in such a way that the fragrance composition is present in encapsulated form, whereby the capsule is on the one hand stable over a long period of time in relation to the filling, but on the other hand is rapidly and completely soluble in water. Another task has been providing a dosage form that is free of ethanol, can be easily transformed into an applicable product by mixing with water and requires no additional packaging to improve sustainability of the product.BRIEF DESCRIPTION OF THE INVENTION
[0014] A first object of the present invention refers to a fragrance tablet, comprising or consisting of a fragrance tablet, comprising or consisting of(i) a carrier and(ii) a fragrance composition wherein(a) said carrier represents a water-soluble powder, and(b) said fragrance composition comprises or consists of(b1) at least one fragrance raw material;(b2) at least one solubilizer; and(b3) at least one pH-adjustor.
[0015] The present invention provides portioned fragrances, each sufficient for one application. For this purpose, the tablets are placed in water, where the fragrance composition almost instantly dissolves. The aqueous fragrance solution thus obtained can be applied to skin and hair like a perfume, or it can be used to scent textiles or hard surfaces. The special advantage is that in one sales container there are single-use tablets, which contain different fragrances per unit, so that an appropriate selection is possible. Moreover, the tablets are free of ethanol and need no additional packaging, which supports sustainability in view of the environment.
[0016] Surprisingly, applicant has found that fragrance compositions, preferably fragrance compositions without ethanol, can stably be pressed into tablets, if the fragrance compositions also contain solubilizers and pH-adjustors. Otherwise, the tablets become initially unsightly and disintegrate. Another advantage is that the tablets are completely dissolved and thus, no waste material remains.Carriers
[0017] Suitable carriers forming component (a) are solid and encompass granules, preferably water-soluble powders. Water-soluble means that at least 100 g carrier dissolves completely in 1 L water (20 dH, 20 °C) within less than 1 minute. Preferably, said carriers are selected from the group consisting of maltodextrin, sorbitol, talc hydrolyzed starch, hydroxypropyl cyclodextrin, xylitol, starch, tapioca clay, microcrystalline cellulose and mixtures thereof. It has been found advantageous using carrier in powder form, wherein said powders show an average particle size ranging from about 100 to about 500 pm, and particularly from about 150 to about 400 pm.Fragrance raw materials
[0018] The "fragrance raw material" in the sense of the present invention forming compound (b1) is therefore any raw material which brings a smell or contribute to have a good scent in the final association of many fragrance raw materials. The term „fragrance raw material" also encompasses a scented raw material or a solvent which improve the intensity of other fragrance raw materials. Particularly preferred fragrance raw materials include all raw materials used in a perfume composition which bring an odor or an impact on the combination of raw materials.
[0019] In a preferred embodiment, the fragrance raw materials are selected from the group consisting of acetals, acids, alcohols, aldehydes, amides, amines, essential oils, esters, ethers, heterocyclic compounds, hydrocarbons, ketones, lactones, nitriles, nitro compounds, oximes, phenols and mixtures thereof.
[0020] The nature of the fragrance raw materials, forming the most relevant part of the pods, is, however, not critical. Basically, all types of fragrance raw materials are suitable to be encapsulated, including perfume mixtures which typically include 50, 70, 100 or more discrete fragrance raw materials Suitable fragrances and perfume oils can be selected from the group consisting of• alcohols,• aldehydes,• amines, amides, nitriles,• esters,• ethers,• ketones,• lactones• and mixtures thereof.In the following these groups are illustrated by various examples, distinguishing between fragrances or perfume oil which are known to the expert by their tradenames or their trivial names.

[0037] Of particular importance to the present invention is the spontaneous and turbidity- free solubility of the tablets as soon as they are introduced into water. On the other hand, the tablets must also have sufficient stability so that they do not disintegrate in the dosage form. When selecting carriers, more emphasis is often placed on tablet stability, which makes it useful to add excipients that, conversely, promote the dissolution rate. In a first embodiment of the invention, these solubilizers may be alkanediols, preferably 1,2-alkanediols having 5 to 12 carbon atoms.
[0038] Said 1,2-alkanediols can be chosen from the group consisting of ethylene glycol, 1,2- propylene glycol, 1,3-propylene glycol, diethylene glycol, dipropylene glycol, triethylene glycol, polyethylene glycol, 1,2-butanediol, 1,2-pentanediol, 1,2-hexanediol, 1,2-heptanediol, 1,2-octanediol, 1,2-nonanediol, 1,2-decanediol, 1,2-undecanediol, 1,2-dodecanediol, 1,2- tetradecanediol or mixtures thereof. Also 1,3-pemtanediol and 1,4-pentanediol represent suitable moisturizers.
[0039] In another preferred embodiment the solubilizers can be selected from the group consisting of C5-C12 alkyl glycosides; particularly preferred are pentyl glucoside, hexyl glucoside, heptyl glucoside and octyl glucoside.
[0040] In another preferred embodiment the solubilizers can be selected from the group consisting of PEG40 hydrogenated castor oil, trideceth-9, polyglyceryl-6-caprylate, polysorbate 20, polysorbate 80, sodium cocoyl glutamate, polyglyceryl-6 oleate, sodium surfactin, polyglyceryl-4 caprate and mixtures thereof. pH-Adjustors
[0041] pH-Adjustors form the third mandatory compound (b3) of the fragrance composition and important for the stability of the tablets. They may be chosen from the group consisting of sodium chloride, citric acid, sodium benzoate, triethyl citrate, triethanolamine, potassium sorbate, amino citric acid, adipic acid and mixtures thereof.Tablet compositions
[0042] In a preferred embodiment said fragrance composition comprises at least 35 wt.-% and preferably from about 40 to about 55 wt.-percent of a water-soluble carrier.
[0043] Further preferred are tablets wherein comprising said carrier and said fragrance composition in a ratio by weight of from about 1:1 to about 1:100 and preferably from about 1:2 to about 1:20.
[0044] In another preferred embodiment the tablet according to the invention comprises or consists of:(a) from about 35 to about 55 wt.-%, preferably from about 40 to about 50 wt.-percent carrier;(b1) from about 3 to about 20 wt.-%, preferably from about 5 to about 15 wt.-percent at least one fragrance raw material;(b2) from about 5 to about 25 wt.-%, preferably from 10 to about 22 wt.-percent at least one solubilizer; and(b3) from about 15 to about 35 wt.-%, preferably about 20 to about 30 wt.-% at least one pH-adjustor on condition that the amounts add to 100 wt.-%.
[0045] The person skilled in the art knows that in the case of only components (a), (b1), (b2) and (b3) are part of the tablet composition, the amounts of the ingredients need to add to 100 wt.-percent. For the sake of good order, it is emphasized that compositions which do not add to 100 wt.-percent are not covered by the invention. As said above, a person skilled in the art, however, will be able to identify compositions in line with the technical teaching provided supra, without additional inventive step.
[0046] It should also be noted that preferred ranges and subranges of components (a), (b1), (b2) and (b3) can be combined.
[0047] In a further preferred embodiment according to the invention the fragrance composition is free of ethanol. As already stated above, this has many advantages, not only in cosmetic terms but also in terms of sustainability.
[0048] Preferably, the tablets show a complete dissolution at 20 °C in water of 16 dH ("Deutsche Harte") at a ratio by weight between tablets and water ranging from about 1:8 to about 1:3, preferably from about 1:5 to about 2:7.Manufacturing process
