Description

Invention Field

[0001] This invention relates to the field of fragrances and discloses a fragrance capsule (pod) for personal care. Background of the Invention The 21st century is also known as the age of hedonism, where both men and women place great importance on appearance. This includes not only dressing appropriately but also choosing the right perfume for different occasions to highlight the desired impression. Perfumes vary depending on the occasion, conveying different messages. In the morning, at the start of the workday, a youthful and fresh fragrance might be chosen; in the afternoon, a sporty scent might be appropriate; and in the evening, a richer fragrance might be preferred. Of course, consumers can choose different perfumes to suit different occasions and meet these needs.

[0003] However, perfumers' palettes of fragrance ingredients seem endless. New products constantly flood the market, replacing underperforming items or seeking new market positioning. But the overwhelming selection can also make it difficult for consumers to choose. Perfume is often a luxury item, and people typically only keep a small amount at home. Buying a new perfume, which may still be an unknown product, only to find that you don't like it and will eventually discard it, is both expensive and unsustainable.

[0004] Therefore, the market has long desired to be able to sell multiple perfumes simultaneously when consumers make a single purchase decision. Currently, the solution is to combine several known perfumes and sell them in miniature bottles identical to the originals. This approach is naturally very complex and expensive, and has not yet become widespread. Another common practice is for perfume shops to give customers a few milliliters of various perfumes in unassuming spray bottles as "samples" when they purchase other items. However, this approach only serves to generate interest.

[0005] Therefore, the market still needs new perfume delivery methods with highly personalized features, especially the ability to select the most suitable perfume for a specific occasion from a variety of perfumes, without having to stock a large number of different perfumes for this purpose.

[0006] Another issue with perfumes and fragrances is their stability and solubility. Therefore, fragrance compositions often contain ethanol, which helps improve the solubility of perfume ingredients, thus enhancing their stability. However, if ethanol is frequently applied to human skin, it can disrupt the skin's natural mechanisms for maintaining health. Furthermore, alcohol has astringent properties, which can lead to dry skin. Therefore, there is a market demand for ethanol-free fragrance compositions.

[0007] Related existing technologies WO 2019 143809 A1 (NOHBO) relates to a hygiene product, a hygiene product bag, and a method of using the hygiene product bag, the hygiene product bag comprising a water-soluble film and a hygiene product sealed within the film. The hygiene product includes a carrier containing butanediol in an amount ranging from about 40% to about 70% by weight based on the total weight of the hygiene product; and an active agent comprising at least one surfactant.

[0008] (BASF) relates to a method for producing water-soluble containers, comprising the following steps: - An open pocket is formed by a first water-soluble film; - Fill at least a portion of the bag with the composition; - Cover the filled bag with a second water-soluble film; - Seal the filled bag with the first water-soluble film using the second water-soluble film. Wherein, at least one of the first or second water-soluble films is a multilayer film comprising at least two film layers L1 and / or L2 or a washing and cleaning active polymer film of any order, and wherein, prior to sealing step d), the second water-soluble film covering the filled bag is in contact with water, thereby obtaining a water-soluble container, the method being used to produce detergent capsules or dishwashing capsules, and the water-soluble container being used to meter detergent into a washing machine or dishwasher.

[0009] (NOHBO) relates to a hygiene product bag and a method of using the same, the hygiene product bag comprising a water-soluble sealing bag in which the hygiene product is sealed. The hygiene product comprises: about 10% to about 40% by weight of a surfactant; about 10% to about 30% by weight of a polyol; about 10% to about 50% by weight of a polyglycerol fatty acid ester (PGE); about 5% to about 40% by weight of a liquid amide; and 0% to about 20% by weight of a phospholipid, wherein the free water content of the hygiene product is about 9% by weight or less.

[0010] NOHBO discloses a storage-stable water-soluble film containing a mixture of hydrophilic polymers and a method for preparing the same. It also discloses a hygiene product bag comprising a water-soluble sealing bag and a hygiene product encapsulated therein.

[0011] (FIRMENICH) relates to a foaming body scrub cleansing device comprising a silicone and a mesh capsule containing at least one soap additive, and a method for manufacturing the device.

[0012] Purpose of the invention Therefore, the problem addressed by this invention is to provide a novel dosage form of fragrance composition that allows for the production of a single-use perfume. The objective is to design a dosage form in which the fragrance composition exists in capsule form, which, on the one hand, remains stable relative to the filler over a long period of time, and on the other hand, dissolves rapidly and completely in water. Another objective is to provide an ethanol-free dosage form that can be easily converted into a usable product by mixing with water, without requiring additional packaging, thereby improving product sustainability. Summary of the Invention

[0013] The first objective of this invention relates to a flavor capsule comprising or consisting of the following ingredients: (i) Sealing bags and (ii) Filler in: (a) The sealing bag contains at least 75% by weight of a water-soluble polymer, and (b) The filler composition comprises or consists of the following components: (b1) At least one spice ingredient; (b2) At least one humectant; and (b3) Water.

[0014] This invention provides dispensed fragrances, each for single use only. To do this, the fragrance capsules are placed in water, where the filler dissolves almost instantly. The resulting aqueous fragrance solution can be applied to skin and hair like perfume, and can also be used to scent textiles or hard surfaces. A key advantage is that a single sales container contains multiple disposable fragrance capsules, each containing a different fragrance, allowing for appropriate selection. Furthermore, these fragrance capsules are ethanol-free, require no additional packaging, and are environmentally friendly and sustainable.

[0015] The principle behind sachets has been reported in the detergent field (particularly in the technology of Nohbo in the US), but its adoption cannot be rushed because fragrances can easily erode, shrink, or tear the polymer film that makes up the capsule shell. Furthermore, existing fragrance compositions contain ethanol for stability reasons. However, as mentioned earlier, the use of ethanol in perfumes or cosmetics is generally controversial. For example, ethanol can damage the skin's sebum layer and is hygroscopic. This means that ethanol absorbs water, leading to dry and cracked skin. In addition, ethanol promotes the production of free radicals. These unstable molecules can damage the skin and collagen structure, which is crucial for maintaining skin firmness. In the worst case, ethanol can cause cell apoptosis. Besides dehydration, free radicals are also a major cause of wrinkles.

[0016] Surprisingly, the applicant discovered that if the fragrance composition, preferably an ethanol-free fragrance composition, contains both a humectant and water, it can be stably encapsulated in a shell (“sealable bag”) of a water-soluble polymer. Otherwise, the sealable bag dries rapidly, becomes unsightly at first, and eventually decomposes. Another advantage is that the sachet dissolves completely, leaving no waste.

[0017] polymer The sealing bag constituting the sachet and encapsulating the fragrance composition needs to be a water-soluble polymer, preferably a readily biodegradable polymer according to OECD 301F standards. The preferred film comprises a polymer containing at least 75% by weight, preferably about 85% to about 95% by weight, of polyvinyl alcohol (PVA) polymer. In a preferred embodiment of the invention, the preferred film comprises a polymer containing at least 75% by weight, preferably about 85% to about 95% by weight, of polyvinyl alcohol (PVA) polymer. Typically, the film thickness used is about 10 to about 100 micrometers, preferably about 35 to about 80 micrometers. PVA films of this quality are available, for example, from Foshan Polyva Materials Co., Ltd.

[0018] Spice ingredients Therefore, in this invention, the term "fragrance ingredient" constituting compound (b1) refers to any ingredient capable of imparting fragrance or contributing to the production of a pleasant aroma in the final combination of multiple fragrance ingredients. The term "fragrance ingredient" also includes flavorful ingredients or solvents capable of enhancing the strength of other fragrance ingredients. Particularly preferred fragrance ingredients include all ingredients used in perfume compositions capable of imparting fragrance or influencing the combination of ingredients.

[0019] However, the nature of the spice ingredients, which constitute the most important part of the sachet, is not a key factor. Basically, all types of spice ingredients are suitable for encapsulation, including spice blends that typically contain 50, 70, 100, or more discrete spice ingredients. Suitable spices and aromatic oils can be selected from the following groups: • Alcohols, Aldehydes, • Amines, amides, nitriles, • Esters, • Ethers, • Ketones, • Lactones • and its mixtures.
